Green hydrogen is set to play a crucial role in Britain's long-term decarbonisation efforts, with significant investments and government support driving the sector forward. The UK is aiming to achieve a 5GW installed capacity by 2030, with Scotland also committing funds to boost green hydrogen development. Despite the progress, challenges remain, such as high production costs and grid limitations. While green hydrogen shows promise for grid resilience and storage, alternatives like battery storage also need to be considered. Industries like ammonia production and steel are identified as key priorities for green hydrogen adoption due to their emissions and capital intensity. However, the technology is not yet practical for domestic use, with a focus on applications in sectors like aviation and automotive. Successful trials in aviation and plans for hydrogen-powered vehicles indicate a bright future for green hydrogen, although widespread adoption may require further innovation and cost reductions.
