The United Kingdom’s energy mix has undergone a historic transformation, marked by the complete phase-out of coal-fired electricity in September 2024. As of early 2026, the electricity sector is dominated by zero-carbon sources, while the broader total energy supply (which includes heating and transport) remains heavily reliant on natural gas and oil.

The UK is rapidly developing a green hydrogen economy to meet its net-zero 2050 target, aiming for 10 GW of low-carbon hydrogen production capacity by 2030, with a strong focus on electrolytic (green) hydrogen. Key projects include industrial-scale production in Tees Valley, Aberdeen, and the North West to decarbonize heavy transport, industry, and power.
