국제 공동 연구를 통한 태양에너지 활용 열화학 물분해 그린 수소 생산 연구 및 E-fuel 생산 연구 동향 보고

초록

Global sustainable energy needs and carbon neutrality goals make hydrogen a key future energy source. South Korea andJapan lead with proactive hydrogen policies, including South Korea’s Hydrogen Law and Japan’s strategy updates aiming for ahydrogen-centric society by 2050. A notable advance is the solar thermal chemical water-splitting cycle for green hydrogenproduction, spotlighted by Korea Institute of Energy Research (KIER) and Niigata University’s joint initiative. This method uses solarenergy to split water into hydrogen and oxygen, offering a carbon-neutral hydrogen production route. The study focuses oninternational collaboration in solar energy for thermochemical water-splitting and E-fuel production, highlighting breakthroughs incatalyst and reactor design to enhance solar thermal technology’s commercial viability for sustainable fuel production. Collaborations,like ARENA in Australia, target global carbon emission reduction and energy system sustainability, contributing to a cleaner,sustainable energy future.
