The National Energy System Operator (NESO) in the UK has released its 2025 Future Energy Scenarios, presenting pathways to decarbonize Britain's energy system by 2050 and achieve clean power by 2030. The report stresses the importance of bold and sustained action across all sectors, identifying green gases, electrification, demand-side flexibility, and infrastructure investment as crucial enablers of success. NESO's Director, Claire Dykta, highlights the four waves of action shaping the energy transition and the need for continued progress. The scenarios explore coordinated investment in renewables, low-carbon fuels, and strategic planning across electricity, gas, hydrogen, and carbon capture infrastructure. Notably, all net zero-aligned scenarios aim to eliminate unabated gas use by 2050, with a significant role assigned to low-carbon gases like hydrogen and biomethane. While some experts raise concerns about green gases for heating, NESO underlines the rapid scaling-up of biomethane and hydrogen infrastructure, stressing the importance of policy clarity. NESO's modeling showcases the potential of demand-side flexibility and smart technologies in reducing peak electricity demand and shifting investment towards low-carbon technologies. The Holistic Transition pathway stands out for meeting both the 2030 and 2035 Nationally Determined Contributions, relying on a mix of electrification, low-carbon fuels, and carbon capture technologies to achieve net zero emissions by 2050.
