Hydrogen is gaining traction in the UK's transportation sector as a promising fuel source for the future. The UK currently has a limited number of hydrogen filling stations, with plans for further expansion to enhance accessibility. The market offers two hydrogen-powered vehicles - the Toyota Mirai and Hyundai Nexo, indicating a gradual increase in consumer options. The UK government is making significant investments to promote the production of green hydrogen through electrolysis, aiming to create a cleaner energy supply and boost job creation. Despite challenges, hydrogen fuel cell technology offers advantages over battery electric technology, including quicker refueling times and extended ranges. Different types of hydrogen, such as green, blue, and grey, play a role in varying energy supplies and functions. While grey hydrogen is currently prevalent, the focus is shifting towards green hydrogen due to its renewable sourcing, aligning with global efforts to reduce carbon emissions in hydrogen production.
