Researchers have developed a PFAS-free dual-layer sol-gel and hydrophobic silica coating that repels water, dust, and dirt while maintaining high light transmission for solar panels. The transparent, self-cleaning coating improved photovoltaic efficiency from 13.90% to 14.56%, demonstrating strong durability and potential for future commercial applications.

Updated building regulations will effectively mandate solar for domestic and commercial buildings in Wales from early 2027. The new rules come ahead of England’s Future Homes Standard, which is also expected to effectively mandate rooftop solar for new builds.

Battery energy storage system (BESS) and demand-side response assets both secure roughly 8% of capacity agreements, according to provisional results, but nuclear leads the pack in first UK capacity market auction of 2026. Results from larger T-4 auction expected later in the month, with generators and energy storage assets vying for multi-year contracts.

Researchers reviewed 110 studies on cold thermal energy storage in liquid-air energy storage, finding that cold storage performance has a far greater impact on system efficiency than previously assumed. While phase change materials offer high theoretical efficiency gains, simpler packed-bed sensible heat systems are currently the most mature and cost-effective option, with further experimental validation needed to bridge the gap to large-scale deployment.

Transport for London on track to receive 65,000 MWh of electricity per year from solar connected directly to one of Europe’s largest private power networks.

The United Kingdom is inviting AI and energy specialists to identify datasets that could make its energy system more efficient, secure and digitized.

State support for solar should result in a record year for PV deployment in the United Kingdom, with strong provisional January data putting market on a good footing. Pipeline of CfD plants due in 2026 plus ramping up of support for rooftop set the stage for accelerated capacity additions.

The UK-based manufacturer has expanded its Ecomod 290HT range with a new 65 kW monobloc air-source heat pump using R290 refrigerant, offering flow temperatures up to 70 C, a COP of 4.6, and cascade capability of up to 7 units.

French utility acquiring one of United Kingdom’s largest electricity distribution networks. Deal subject to regulatory approval with completion expected mid-2026. Engie says transaction in line with company’s broader electricity network infrastructure ambitions.

Investment and support could make small-scale space-based solar power (SBSP) viable, with potential for electricity generated in orbit to participate in UK contracts for difference (CfD) scheme according to new report. Launch costs have biggest impact on levelized cost of electricity (LCOE), according to analysis.
