Hyosung’s commitment to green management: The numbers speak for themselves Hyosung’s commitment to green management: The numbers speak for themselves The uprising trend for future-oriented business: ESG Concerns about climate change, global warming, and depleting resources have brought the idea of a new growth paradigm to the fore. Once foreign to many, the word ‘sustainable growth’ has become the uprising trend for future-oriented businesses. ESG, the acronym for Environmental, Social, and Governance, now has become a critical business milestone in their business direction. At the same time, it is also true that some businesses conveniently chose to jump on the bandwagon to claim that they have adopted ESG management just because sustainability is in fashion. Here we have a company that has advanced our life for humanity; its business mission leading in various activities designed for environmental protection and carbon neutrality. That is no other than Hyosung, a leader in technology. To minimize its corporate footprint, Hyosung has been dedicated to sustainable growth by developing products and technology designed to facilitate the hydrogen economy and develop resource recycling technology and eco-friendly materials. And we at Hyosung stand by our numbers. Our environmental research and development investments are estimated to be over KRW104.3 billion (USD75 million), and our registered patents are over 3,310. Hyosung’s mission to sustainable management, ‘Green Management Vision 2030’ The most notable eco-friendly activities pursued by Hyosung include its initiative called ‘Green Management Vision 2030.’ The initiative has four targeted goals of greenhouse gas reduction, development of eco-friendly technology and expansion of subsequent markets, building a green company culture, and enhancing stakeholder trust. Hyosung has pursued subsequent strategies alongside its company-level climate change strategy for sustainable management. 1) Greenhouse gas reduction In line with the nationally determined contribution target set forth by the ROK government in 2021, Hyosung has renewed its commitment to greenhouse gas reduction from a 20.5% cut in 2017 to a 14.5% cut in 2018 under its Green Management Vision 2030. As such, the company has established a mid-and-long term reduction plan across the whole business encompassing planning, research, and production. On top of this, the risk management process on climate change is now in place to identify risks and opportunities that climate change brings and to update risk management status annually for the sake of ESG management. 2) Development of eco-friendly technology and expansion of subsequent markets Based on the goal of developing eco-friendly technology and expanding subsequent markets under Vision 2030, Hyosung has put the utmost effort into R&D in technology and product development to secure new growth engines and accomplish sustainable growth. Let’s take a look at some of those examples. ■ A key renewable energy technology, energy storage system or ESS that enables storage of electricity for future use Energy storage system or ESS, which helps save electricity for future use, is emerging as one of the most important facilities for the energy industry and electricity of the future as renewable energy power generation is growing in share. Hyosung offers a whole life-cycle service on ESS encompassing customized consulting, system building, and post-management. Our technology has received rave reviews from electricity powerhouses in Europe. Hyosung Heavy Industries signed a contract in 2021 to supply 50-megawatt energy storage systems to U.K. energy infrastructure investment company Downing LLP. With this deal, Hyosung is providing a total ESS solution to the UK that will involve designing, supplying, and a 10-year maintenance service. It is noticeable that the ROK company’s proprietary technology has been recognized by the UK, a country that has been leading the world’s efforts in carbon neutrality and a transition to renewable energy. ■ Insulating materials such as transformer and gas insulated switchgear replaced with green products Hyosung Heavy Industries, a leading provider of electric equipment such as transformers and gas-insulated switchgear that are key to the electrical grid, has led the efforts to develop and commercialize green insulating materials. Hyosung has developed an eco-friendly transformer using ester oil as alternative insulation, reducing environmental impact, and enhancing safety against fire. Hyosung has been supplying this eco-friendly transformer to overseas markets such as Europe and the Middle East. The company also developed 170kV Gas Insulated switchgear utilizing Novec gas blending in 2021 and plans to adopt it to newly built power transmission plants and projects designed to replace outworn facilities to reduce greenhouse gas emissions in electric power systems. ■ To build a large-scale liquefied hydrogen plant to expand the hydrogen business Committed to carbon neutrality, Hyosung Chemical and Hyosung Heavy Industries have been proactively pursuing the hydrogen business. With an existing hydrogen charging system, Hyosung supplies a charging system for passenger and commercial vehicles and plans to provide dedicated charging stations for heavy machinery in line with the hydrogen fuelization efforts for excavators and forklift trucks. In addition, Hyosung is constructing the world’s largest liquefied hydrogen plant designed to improve the efficiency of hydrogen storage and transportation. Liquefied hydrogen offers much better efficiency in storage and transportation thanks to its higher density than that stored in the air. Hyosung plans to contribute to facilitating hydrogen mobility by proactively producing liquefied hydrogen. In response to the growing trend in sustainable mobility and transition to the hydrogen economy, Hyosung joined hands with the world’s leading gas name Linde Group to build a 13,000-ton liquefied hydrogen plant by 2023 with an estimated investment of KRW300 billion (USD215 million). It will be built on the site of Hyosung Chemical’s Yongyeon factory. ■ TANSOME®, lighter but stronger than steel Hyosung Advanced Materials developed TANSOME®, carbon fiber 10 times stronger than steel. It is one of the essential materials for producing fuel tanks for hydrogen vehicles. The carbon fiber-based high-pressure tanks are much lighter while promising better fuel efficiency. Hyosung sees a future where its TANSOME will be critical in green energy and the automobile industry where weight reduction is imperative. ■ Low carbon lyocell tire cords Hyosung Advanced Materials has developed lyocell tire cords derived from woods used for high-speed vehicles for its durability. Using materials with minimum pollution impacts, unlike conventional materials such as rayon and nylon tire cords which generate pollutants including carbon bisulfide and sulfureted hydrogen, lyocell tire cords offer 30 percent lower greenhouse gas emissions. ■ Eco-friendly engineering plastic material, polyketone Based on its proprietary technologies developed in 2013, Hyosung Chemical produces engineering plastic POKETONE™. Made of carbon monoxide (a leading cause of air pollution), Hyosung’s polyketone uses 0.5 tons of carbon monoxide for 1 kg of Poketone production. The material is approved by the US FDA for its non-toxic characteristics and thus has been widely used for kids’ toys, food processing conveyors, and cosmetic packaging. It is now being adopted in new sectors such as automobiles, electric and electronic gear, and drilling pipes. Especially, Polyketone is safe and durable for its impact and abrasion resistance, and ductility. It is a semi-permanent material that doesn’t require the replacement of components and thus offers higher sustainability than general or disposable plastic materials. As a leading eco-friendly plastic material, Polyketone also offers lower global warming potential (GWP) compared to other engineering plastics and is proven through LCA or life cycle assessment and other external reviews to be effective in reducing CO2 emission. Hyosung Chemical has expanded its application to broader areas such as building materials, automobiles, household items, and leisure goods. ■ Recycled polyester yarn created from post-consumer PET bottles, regen® With plastic waste emerging as a global issue, Hyosung TNC developed 100 percent recycled polyester yarn from discarded PET bottles ‘regen® polyester’ back in 2008. The textile powerhouse Hyosung TNC’s regen® polyester offers the same level of quality and performance as conventional polyester materials. It is loved by leading fashion names worldwide for its outstanding quality and stable supply thanks to Hyosung’s extensive global network. It also offers 60 percent less CO2 emissions than other polyester products. Hyosung TNC has been producing ‘regen® ocean nylon’ since 2007, a recycled nylon yarn from fishing net waste that accounts for a large percent of ocean waste. These eco-friendly yarns, regen® polyester and regen® ocean nylon, contribute to sustainability and circular economy by dramatically reducing landfill waste and CO2 emissions. As a leader in the circular economy for the textile industry, Hyosung offers global best practices in quality and stable supply. ■ Bio-based spandex The global number one spandex provider Hyosung TNC learned from the Life Cycle Assessment that materials before they are put into the manufacturing process, have the biggest environmental impact. To address this, the company has developed bio-based spandex to supply them for global leading fashion brands. It is currently working on biodegradable polyester yarn development as part of its effort to diversify its bio yarn portfolio. 3) Sustainable corporate culture In 2021, Hyosung ran an internal idea competition for energy saving and greenhouse gas reduction. Out of the 211 ideas submitted, ranging from energy consumption saving in business sites to product development, 10 passed the thorough deliberation process, and the selected ones have all been implemented to reduce greenhouse gas emissions. Assembly lines at Hyosung TNC are all in the process of transitioning to low carbon energy consumption. It uses waste supplied from incineration facilities nearby as a renewable energy source while using biogas produced from an anaerobic digestion system installed in its factories. Hyosung also ran an internal campaign last year to do away with disposable goods in the workplace. Since 2021, paper cups for water coolers in the company have been removed, and instead, it supported employees’ purchase of tumblers. In 2020 alone, it is estimated that around 190,000 paper cups were used at the headquarters of Hyosung TNC. Thus, we believe that by simply cutting down on our use of paper cups daily, we can reduce our CO2 emissions by up to 2 tons per annum. 4) Enhancing stakeholder trust Hyosung has shown an outstanding performance in the CDP (Carbon Disclosure Project) scores, the most trusted assessment of businesses’ climate change response. In the 2020 CDP Climate Change Awards, Hyosung Advanced Materials was awarded Carbon Management Honors Club, an award for the top five performers, and Carbon Management Sector Honors for the top-notch CDP scorers in respective sectors. CDP is a not-for-profit organization based in London, UK, that discloses environmental impact information such as climate change strategy, CO2 emission, and carbon management of major listed businesses in 91 countries. What we have here is just part of a much larger story regarding Hyosung’s commitment to sustainable management. We at Hyosung believe the future for a fully sustainable Hyosung is just around the corner, with all members of the Hyosung family being committed to a better life for humanity. Hyosung continues to trailblaze daily to honor its carbon reduction commitment to identify sustainable new growth engines and protect our environment. Get a closer

Hyosung’s leading action to climate change Hyosung’s leading action to climate change Hyosung Group expanded its ESG Management Committee in April 2021 and has long committed to research and development efforts and prompt sustainability decision-making. As part of this, it has also announced ‘Green Management Vision 2030’, designed to lead a better life for humanity. One might wonder what has driven Hyosung’s commitment to the issue of climate change. Last July, the oldest glacier in Switzerland, Rhone Glacier, was covered with blankets. The glacier has lost around 40 meters in ice thickness in the past decade due to climate change, and thus Swiss authorities decided to halt the ice melt by covering the glacier with white blankets. Switzerland is not the only country to suffer from climate change. It has affected every bit of the world. The US has been afflicted by heat waves, flooding, and bushfires, while Europe has witnessed the frequency of heat waves jumping 3 to 4 times over the past 42 years. The UN Secretary-General Antonio Guterres warns that humanity is facing ‘collective suicide’ without prompt action on climate change. Corporates with a global footprint should take the lead Since the Industrial Revolution, corporates have seen their production volume grow exponentially while humanity, in turn, can purchase things whenever in need. However, we have not paid enough attention to carbon dioxide emissions in the manufacturing, shipping, and development process, being indifferent. Situations have changed, governments worldwide are scrambling to strengthen environmental regulations, and consumers are more conscious of the carbon footprint of the products they purchase. Multinational companies are thus faced with this imminent challenge of shifting their technology focus from convenience to the survival of humanity and the environment. Hyosung’s response to climate change: Green Management Vision 2030 Hyosung’s Green Management Vision 2030 has four objectives: greenhouse gas cut, development of green technology and expanding the subsequent market, building green corporate culture, and enhancing stakeholder trust. The following plans for each objective are established respectively to pursue and implement climate change strategies at the corporate level. Hyosung aims to reduce its carbon emission by 14.5% compared to 2018 by 2030. To achieve this goal, the company has been transitioning to green fuels. Hyosung TNC, for example, has been implementing a low-carbon energy policy for its assembly lines. It uses heat waste from nearby incineration plants and taps into biogas from anaerobic digesters within its assembly lines. Each factory sets up its annual environment investment plan, making efforts toward saving energy. Hyosung has also been pouring efforts into building a green corporate culture. Green procurement practices and in-house chemical management systems are pursued, and air and water pollutant management system have been advanced to minimize carbon footprint. Also, working closely with its vendors and partners, Hyosung supports its energy-saving efforts, mutually benefiting through growth and development. Hyosung has been forthcoming in disclosing related information as part of its efforts to enhance stakeholder trust. In line with the Task Force on Climate-related Financial Disclosures (TCFD) created by the Financial Stability Board, Hyosung issues sustainability reports annually and has been building a green management system by obtaining green certifications across its production sites. Hyosung Advanced Materials has acquired the ISO 50001 certification for the energy management system, while Hyosung Chemical’s Yongyeon Plant has obtained ISO 14001 certification for its environmental management system. A green society built on our green portfolio As a responsible global corporate, Hyosung has been making tangible contributions to building a green environment with its products while continuing to develop related technologies to transition itself into a truly green business. Hyosung TNC offers the fiber ‘regen polyester’ made from recycled PET bottles and ‘regen ocean nylon’ on recycled fishing nets from the ocean. In the meantime, Hyosung Advanced Materials pursues green management on three pillars zero emission, zero waste, and zero impact. Its tire cord product is made with lyocell extracted from wood, emitting 30% less carbon dioxide than existing rayon and nylon-based tire cords. It also supplies ‘TANSOME®,’ the carbon fiber used for green energy sectors such as hydrogen and car light-weighting. Hyosung Heavy Industries has pursued various renewable energy businesses, including hydrogen stations, liquefied hydrogen, wind turbine, and energy storage system. It has also been very active in research and development on transitioning existing products, including transformers, into greener products. Additionally, it has adopted green construction technologies while obtaining green construction certifications and sustainable landscape design. Hyosung Chemical has continued R&D efforts to expand its green business portfolio. Based on proprietary technologies developed in 2013, it has acquired the green engineering plastic Polyketone, which is widely applied to various sectors such as automobiles and everyday goods. Hyosung continues its research efforts to use the material across our daily lives broadly. Sustainability creates business opportunities Our collective understanding of the environment has increased going through the pandemic and climate change. Multinational companies have a new homework to solve since consumer preferences have changed, ‘Greensumers’ who prefer eco-friendly products that consider the environment is increasing. With these changes, Hyosung has been agile in exploring and creating business opportunities in green markets and fulfilling its corporate responsibility. Hyosung will relentlessly make efforts to make a better planet, from its manufacturing processes to finished goods, across its entire business value chain. By advancing the green management system, developing green products, and actively communicating with stakeholders, Hyosung will continue focusing on creating a society where humanity, our business partners, nature, and the environment can harmoniously coexist and prosper altogether.

The charm of circular economy captivated the world, turning waste into treasure The charm of circular economy captivated the world, turning waste into treasure Abnormal weather conditions that hit the world last summer are a cause for concern. The United Kingdom, known for its cool summer, suffered heat waves as high as 40 degrees in Celsius, so much so that its schools had to close. Greenland lost 18 billion tons of ice in just over three days. The US suffered the most severe heat wave in 90 years, where 28 states out the 50 went around with excessive heat warnings. With these widespread abnormal weather conditions, awareness of the environment has been raised. As such, attention to a circular economy about protecting the environment against climate change has grown accordingly. The circular economy is a must for carbon neutrality The circular economy is a model adopted by Europe designed to avoid the existing linear model where raw materials are mined for production and used products are thrown away after use. In a circular economy, we reuse the used raw materials in every possible way. A successful transition into this renewable energy-based economy is the key to achieving carbon neutrality. Production and disposal of product waste are responsible for 45% of greenhouse gas emissions. In a circular economy, we should be able to cut greenhouse gas emissions significantly and thus able to achieve net zero. We have a long way to go. According to the OECD, out of the 15% of plastic waste collected for recycling, only 9% was recycled in 2019. Half of the plastic waste ended up in landfills, nearly 1/5 incinerated. We desperately need an economic model that enables upcycling. Global efforts to build a circular economy We are witnessing international efforts being placed forth for a circular economy. The EU announced the New Circular Economy Action Plan in March 2020, making all plastic packaging recyclable or reusable. The Fifth session of the United Nations Environment Assembly (UNEA-5) also agreed to develop an international agreement on plastic pollution prevention by 2024. Korea is no exception: It is pursuing legislation requiring over 30% of PET bottles to be made of recycled materials by 2030 under the K-Circular Economy Implementation Plan for Net Zero, announced in December last year. Biden administration has pledged to succeed President Obama’s renewable energy and energy efficiency policy and promoted the Green New Deal alongside implementation plans for a carbon tax and Carbon Border Adjustment Mechanism. The US is now back to the Paris Agreement as of January 20th, 2021, and is set to achieve net zero across the whole economy by 2050 with its Clean Energy and Infrastructure Plan. Multinational companies are also playing their role, and here are some of the examples of those corporates that are pursuing a circular economy as well as environmental protection. The American recycling company TerraCycle introduced LOOP in 2019, a circular platform built on recyclable packaging materials. LOOP offers normal goods such as shampoo, detergents, toothpaste, and food such as ice cream and chocolate in stainless containers and glass or aluminum bottles. Customers returned the containers after they consumed the products for recycling, similar to milk delivery services when used milk bottles were collected and returned for reuse. The platform, designed to reduce plastic container waste, is currently available in the US, Canada, and the UK. In France, known as smoker’s haven, a start-up, Cy-Clope, has launched a cigarette butt recycling service based on circular economy. A single cigarette butt can pollute 500 liters of water, taking as long as 12 years to decompose. The French start-up collects cigarette butts from the streets and recycles them, and its collecting container can hold up to 10,000 cigarette butts, eventually recycling 100%. Cigarette filters are recycled as plastic materials, while the rest are used for compost. Hyosung, a leader in circular economy with its post-consumer PET bottle-based fiber ‘regen®’ A company has been there at least a decade earlier than TerraCycle and Cy-Clope. Hyosung TNC, a chemical fiber affiliate of Hyosung Group, introduced the first Korean recycled polyester fiber regen® in 2008. The yarn is created from post-consumer PET bottles, not existing petrochemical materials. 50 plastic bottles of 500ml are used for one kilogram of regen. As it doesn’t consume petrochemical materials, it also contributes to saving up our limited resources from the earth. International fashion names are using regen® to produce eco-friendly clothing and bags. Since its inception in 1966, when its mother company Tongyang Nylon was established, Hyosung has led new material development R&D efforts in Korea over the past 60 years. Hyosung regen® has acquired Control Union’s Global Recycle Standard (GRS) certification in 2009 and Eco-Mark from the Japan Environment Association for its contribution to sustainability in the textile industry. Hyosung’s 100% recycled polyester fiber leading ocean protection With its dedication to protecting the ocean, a vital buffer against climate change's impacts, Hyosung noted that 80% of ocean waste is plastic. At the same time, 1/3 of them are generated from vessels. Marine debris is collected and disposed of via incineration, creating another layer of environmental degradation. Hyosung’s solution to this problem is ‘regen ocean polyester’ recycled from marine waste. It has acquired the Ocean Bound Plastic certification, the first of its kind for a Korean company. Ocean-bound plastic is abandoned plastic waste recovered from areas up to 50km inland from waterways or 200meters from rivers and thus often not subject to inland waste or recycling system. Hyosung’s regen ocean polyester is made from PET bottles found in the ocean and waterways, fully meeting the strict standards of the OBP. Thus, Hyosung truly fulfills the spirit of “recycling” by collecting those pollutants from the ocean and ‘recycling’ them. The company has developed a thorough process for the recycling process and specification management for quality control. Hyosung TNC takes sustainability and circular economy seriously and has made its regen products one of the key growth engines for the company’s future. World’s first recycled nylon from fishing net waste Building on its advanced nylon technology, Hyosung TNC has introduced a recycled nylon fiber from ocean waste to contribute to building a new circular economy model. Nearly out of the 8 million tons of plastic waste being dumped into the ocean, 640,000 tons are from fishing net waste. Hyosung’s regen ocean nylon, launched in 2007, is the world’s first recycled nylon fiber made from fishing net waste. Turning discarded fishing net waste into high-quality yarns is quite challenging because the marine debris, after being soaked in the salty waters, often comes with many impurities and thus making it tricky to extract caprolactam, a key material for nylon yarns. So much so that there are only two companies in the world with their proprietary technology of nylon recycling. Hyosung TNC was the first company to introduce recycled nylon worldwide based on its decades-old technology and R&D efforts. The company has signed MOUs with Korean local governments such as Busan City and South Jeolla Province in 2021 to expand its regen ocean nylon to increase the capacity to 150 tons per month. We at Hyosung spare no effort in resource sustainability and environmental protection Hyosung offers other recycled fibers such as regen® spandex, recycled spandex from reclaimed waste. regen® spandex is the only commercially available recycled spandex that can be applied for various use and is naturally in high demand. It is made with pre-consumer waste from the company’s virgin creora® spandex yarn manufacturing process. Hyosung’s unparalleled commitment to a circular economy is proven by its decades-long focus on research and technology since the 1960s when it opened its first research center. With its entire portfolio of regen polyester recycled from PET bottles, regen ocean polyester made with PET bottles found in waterways, regen ocean nylon made from fishing net waste, and regen® spandex from reclaimed textile waste, Hyosung continues its commitment to sustainability and environmental protection for the sake of a better life for hum Get a closer

Did you know the world’s first hydrogen law was introduced in Korea? Did you know the world’s first hydrogen law was introduced in Korea? Everything you need to know about hydrogen, as seen through Hyosung’s hydrogen business Did you know that the Republic of Korea was the first country to legislate a hydrogen law in the world? Yes, the Korean government promulgated the Hydrogen Economy Promotion and Hydrogen Safety Management Act or the “Hydrogen Act.” Yet Korea is not alone. The world is spotlighting hydrogen energy; an energy source recently sought after the most in the world. The U.S. Department of Energy has also announced the Hydrogen Program Plan, while U.S. President Biden promised a $9.5 billion fund to cut clean hydrogen costs and facilitate commercialization. The EU also has revealed the EU Hydrogen Strategy and launched the European Clean Hydrogen Alliance (or ECHA) as part of its efforts to transition to the hydrogen economy. China aims to meet a target of 1 million hydrogen vehicles by 2030. What is it about hydrogen that makes it so much in demand? More energy efficiency, lower greenhouse gas emission The answer lies in its eco-friendly and economic characteristics. With the growing call for doing away with fossil fuel usage to save our ailing earth from greenhouse gas, demand for electricity as an alternative to fossil fuels soared. Electricity can be generated by clean energy sources such as solar and wind power. However, they require huge installation space and are susceptible to climate conditions. That is where hydrogen comes in. Unlike underground resources, hydrogen can be artificially produced with technology. It is the most abundant element in the universe, accounting for about 75 percent of its mass. It is a clean energy source that makes water when mixed with oxygen. It has the highest energy density of all known substances, promising excellent energy efficiency. One might wonder. How come it takes so long for humanity to start utilizing it despite all the merits it offers? Re-emerging as a promising energy resource Humanity has long known about the possibility of hydrogen as an energy resource. When Apollo 11 made the first landing on the moon, it housed three hydrogen fuel cells. Hydrogen emerged as a promising energy resource in 1973 when the oil crisis hit the world. With the shale oil boom, however, hydrogen was put on the back burner. While humanity was preoccupied with the low-price and fast development of energy resources without considering environmental consequences, the earth’s ecosystem has been collapsing rapidly. It has come to the point where the development of alternative energy resources for the sake of the environment and humanity can no longer be put on the back burner. Thus, hydrogen is rapidly gaining ground. Now efforts are being put forth to find ways to use hydrogen in a more efficient and eco-friendly manner before the world transitions into a hydrogen economy. Hyosung’s hydrogen business will provide the most idealistic way of utilizing the promising energy resource that could be a definitive answer to humanity’s present and future. Hyosung is committed to hydrogen The biggest stumbling block to the commercialization of hydrogen is the lack of charging infrastructure. No matter how efficient and eco-friendly it is, not many people will be ready to opt for the energy resource. In other words, they are going through a great deal of inconvenience due to the lack of supporting infrastructure, such as charging stations. As such, Hyosung has been taking the lead in establishing a charging station network nationwide to facilitate our national paradigm shift into hydrogen. Starting from CNG and LCNG charging facility businesses in 2000, Hyosung has built its gas compression and charging technology and experiences over the past two decades. Building on this, Hyosung introduced the nation’s first hydrogen charging station in 2009; it is a leading supplier of hydrogen charging stations in Korea, with 25 operating in major cities and 16 in the pipeline. When it comes to nylon liner resins and carbon fibers, the essential materials for hydrogen storage containers, Hyosung is the main supplier. Storage of hydrogen requires high-pressure and ultra-light containers. Hyosung TNC has developed and supplied Nylon liner resin for the first time in Korea. Hyosung Advanced Material’s proprietary carbon fibers, the fourth of their kind in the world weigh a mere 1/4 of that of heavy steel and 10 times the strength, suitable for hydrogen storage containers. Carbon fibers are also used for tanks for hydrogen vessels. Hyosung is to invest KRW1 trillion by 2028 to build an annual capacity of 24,000 tons to meet the growing demand for hydrogen cars. The future of hydrogen will run alongside Hyosung’s hydrogen business As with anything in life, there is always room for improvement. Hydrogen is no exception. It is a gas. When it is in gas form, its volume is huge, and it has to be stored at high pressure for efficiency’s sake. To store the high-pressure hydrogen gas stably, specially designed containers are required. Should the volume and weight of the gas increase, transportation costs and establishing charging stations would inevitably become challenging. However, when it is cooled down to minus 253 degrees, it becomes liquid, called liquid hydrogen. Its volume is 1/800 that of gaseous hydrogen, which in turn requires less landmass for charging stations and lower costs for related facilities and transportation. It is also stored at atmospheric pressure with higher stability. On top of this, charging is more convenient and easier as it doesn’t ascertain levels of pressure during charging – the same way as you would fuel a gasoline vehicle in a gas station. As such, liquid hydrogen is the key to a rapid transition to hydrogen energy. Hyosung has partnered with a global gas leader Linde Gas to build a liquid hydrogen plant to equip it with the liquid hydrogen production and charging network enabling large-scale storage and transportation. The plant, once built, is expected to kick off its operation by May 2023 in Ulsan, Korea, with a capacity of over 13,000 tons of liquid hydrogen. Upon launching the facility, Hyosung plans to invest KRW 1 trillion over five years to expand it to a capacity of 39,000 tons per annum. Once the distribution of liquid hydrogen grows, it will naturally be followed by a rapid establishment of related infrastructure. As the cost of building charging stations gets cut, the saved-up funds can be funneled to build more stations. Hyosung is to establish a 30 liquid hydrogen charging station nationwide with the planned launch of the liquid hydrogen plant. A greener hydrogen eco-system It would be difficult to call hydrogen a true clean energy resource if its production process had entailed carbon dioxide emissions. Hyosung strives to develop the CCUS (Carbon Capture Utilization Storage) technology that captures carbon dioxide emissions at production. The company is also leading the influx of the green hydrogen supply, produced by an electrolyzer based on renewable energy. It does not emit any carbon dioxide during the production process, and thus it is called the ‘ultimate green hydrogen.’ As the first Korean company to develop a 750kw wind turbine, Hyosung is also planning to build an 8MW wind farm. When it comes to new and renewable energy, storage of produced energy is critical as it is vulnerable to surrounding environments such as climate. Hyosung is also a leading player in ESS or Energy Storage System in Korea. A new era ushered in by hydrogen The Hydrogen Council, a global initiative of leading companies, estimates up to 546 million tons of global hydrogen consumption by 2050, which will replace 13.26 billion barrels of crude oil and account for nearly 20 percent of the global energy demand. Hydrogen stands to determine the future of humanity and the environment, and Hyosung has played and will continue to play a key role in our transition to a hydrogen society. As a holistic supplier responsible for the whole value chain encompassing production, transportation, and charging, Hyosung has been trailblazing the global industry. Please stay tuned with us while we at Hyosung continue to march into a new era of hydrogen! Get a closer
