A 177,000-mile network of gas pipes underground in Britain could play a crucial role in the country's transition to clean energy. Energy industry experts suggest repurposing the existing gas infrastructure to transport hydrogen, supporting the UK's Net Zero plans. The director of regulation at Wales & West Utilities highlighted the importance of utilizing the 285,000 kilometers of pipes already in place to transport hydrogen. This initiative could be cost-effective, with estimates indicating it would be £28 billion cheaper to repurpose the network than to decommission it. The push for hydrogen comes as the UK witnessed a significant shift in its energy landscape in 2024, with renewable energy hitting record highs and fossil fuel power reaching record lows. The country's electricity generation became the cleanest ever, with renewables and nuclear sources contributing 58% of the power. As the UK aims to reduce carbon emissions, the focus is on reducing reliance on fossil fuels for heating and cooking. The transition to burning hydrogen, which only produces water as a by-product, is seen as a promising solution. Despite concerns about hydrogen's flammability and the need for fossil fuels in its production, the potential benefits for reducing carbon emissions are significant. The UK's progress in reducing carbon emissions is evident as the country shifts away from polluting fuels and increasingly embraces renewable sources. Wind energy is projected to surpass gas as the largest power source in 2025, marking a significant milestone in the UK's energy transition towards a cleaner and more sustainable future.
