Role of Compound Semiconductors in Green Hydrogen Ecosystem

This white paper details the role of compound semiconductors within the green hydrogen ecosystem, focusing on their potential applications and benefits. It outlines how these semiconductors can enhance renewable energy generation, particularly in wind and solar technologies, by improving power conversion efficiency and reducing energy losses. The paper discusses the importance of power electronics in electrolysis, which is essential for producing green hydrogen, and how future compound semiconductors could improve electrolyser performance. Additionally, it highlights the applications of compound semiconductors in transportation, particularly in fuel cell electric vehicles (FCEVs), which can provide zero emissions and quick refuelling times. The paper also addresses the challenges faced in adopting these technologies, including higher production costs and the current limitations in hydrogen supply infrastructure. Overall, it presents a comprehensive view of how compound semiconductors can contribute to a more efficient green hydrogen ecosystem, supporting the UK’s Net Zero targets.
