The article discusses the significant role hydrogen, particularly green hydrogen, plays in the global energy transition towards a more sustainable future. Notably, low-carbon hydrogen, including green and blue hydrogen, is identified as vital for reducing carbon emissions. While the UK was once a leader in the global hydrogen economy, delays in policymaking have caused a setback, prompting an injection of £21 million into hydrogen projects to meet net zero targets. The importance of green hydrogen, produced through renewable sources like water electrolysis, is underlined as a crucial tool for decarbonization in various sectors. However, the Energy Networks Association and Hydrogen UK warn that the UK's delay in establishing a robust hydrogen supply chain may hinder decarbonization efforts and economic benefits. They call for immediate government action to legislate for investable hydrogen production, streamline application processes, and strategize the hydrogen supply chain. Green hydrogen is seen as a promising avenue for emission reduction in challenging sectors, despite current cost and infrastructure challenges. The article stresses the necessity of government support and a clear supply chain strategy to maximize the economic advantages of a strong domestic hydrogen industry.
