A recent University of Manchester study titled 'On Hydrogen' has shed light on the future of hydrogen as an energy source, providing in-depth analysis, evidence, and policy recommendations to address the key challenges surrounding hydrogen in the UK. Baroness Brown of Cambridge, in a foreword to the report, raises concerns about the hype surrounding hydrogen in the past decade, cautioning that the 'hydrogen bubble has burst.' However, amidst these warnings, initiatives like HyNet in the North West are demonstrating potential in advancing decarbonisation efforts and industrial growth, especially through projects focused on carbon capture and storage. The UK government's £22bn pledge for projects like carbon capture clusters on Merseyside and Teesside indicates a commitment to meeting climate goals while creating job opportunities. Baroness Brown highlights the importance of green hydrogen in tasks like decarbonizing steel production and generating sustainable fuels, presenting it as a growth opportunity for the UK. The report underlines the need for government support to establish a strategic reserve of hydrogen and capitalize on the UK's resources and expertise in driving the growth of the hydrogen industry. 'On Hydrogen' features contributions from academics on various aspects of hydrogen production, storage, decarbonization, and its role in industry and transportation, emphasizing the significance of hydrogen in the transition to a sustainable future.
