Energy Shift: National Grid Requests a Second Demand Flexibility Trial
Green Technology and Hydrogen Networks Transform the UK's Energy Landscape
The UK is making significant strides in implementing green technology and hydrogen networks, with a focus on decarbonizing energy-intensive industries and heating systems.
Launch of Demand Flexibility Service
The National Grid ESO's Demand Flexibility Service, launched on November 1, is aimed at providing additional flexibility when national demand peaks. This service will play a crucial role in managing the variability from increasing renewable generation.
Hydrogen as a Key Player
The H100 Fife project, part of the Gas Goes Green initiative, is a world-first initiative demonstrating the role of hydrogen in achieving net-zero. SGN, a UK gas distributor, has invested £32 million in the project, which aims to save 2,650 tonnes of CO2 over its lifetime. The hydrogen will be produced using electricity from ORE Catapult's 7MW offshore wind turbine and stored in six tanks, enough to heat up to 300 homes.
Government Investment in Green Technology
The UK government has announced a £65 million investment into the development of green technology as part of the Industry Transition Programme. This fund aims to assist both on a corporate level and nationally and regionally, with a focus on supporting climate governance and developing monitoring, reporting, and verification practices.
Hydrogen Blending in Gas Networks
The UK government is exploring hydrogen blending into the Great Britain gas transmission network, initially considering blends of up to 2% hydrogen by volume and previously up to 20% in distribution networks. This strategy aims to leverage existing gas infrastructure to provide flexible, low-carbon energy that supports industrial decarbonization and energy security while minimizing consumer costs.
Expansion of Renewable Energy Capacity
As of April 2025, renewables constitute 41% of the UK’s energy mix, with wind power (21.7%), biomass (6.9%), and solar (5.2%) leading. The UK aims to grow wind capacity to 50GW by 2030 (currently 11GW) and solar capacity to 70GW by 2035 (currently 14GW), which will support decarbonizing energy-intensive industries through cleaner electricity sources.
Green Heating Systems and Heat Pumps
The residential sector—a major carbon emitter—is targeted for a 30% reduction in household carbon emissions by 2030 through making heat pumps more affordable and scaling up their installation capacity. Supporting efficient use of existing heating and shifting electricity demand away from peak hours also form part of this strategy to decarbonize heating systems.
Energy System Flexibility and Storage
The UK is advancing interseasonal energy storage and demand response projects to manage variability from increasing renewable generation. For example, projects like 4D heat use excess wind energy for residential heating. Carbon capture, utilization, and storage (CCUS) also remain critical for balancing grid stability in energy-intensive sectors.
Clean Technology Adoption
Small-scale clean tech installations are rapidly growing, signaling broader adoption in industry and homes that complements hydrogen and renewable strategies.
These coordinated approaches align with the UK’s commitment to decarbonizing the energy system by 2035 and achieving net zero emissions economy-wide by 2050.
