Sungrow Hydrogen has started production at China’s largest dual-tech green hydrogen project combining PEM and alkaline electrolyzers, while HNO International has partnered with Zhuhai Topower to pilot its modular hydrogen platform in China.

The PV-driven redox flow battery can reportedly achieve a maximum solar-to-output electricity efficiency of 3.11% during a 36-hour period. The system incorporates a 25 cm2 heterojunction photovoltaic device and is based on a neutral pH aqueous iodine-bromine redox couple.

Four balancing PPAs will see ElectroRoute trade Low Carbon solar assets in UK electricity market. The agreements are set to run until 2028.

Integrating monocrystalline solar cells with metal standing seam roof panels, Roofit Solar sees opportunity in retrofit and new-build properties. pv magazine catches up with chief growth officer Greg Grace to discuss switching to TOPcon, adding color, energy security, and pitching rooftop solar to the Prince of Wales.

Building regulations in England support growth in demand for rooftop solar as new-build properties make up significant share of small-scale PV installations. Strong installations in first quarter of 2025 were followed by a new single-day record for UK solar generation in April.

Heat pump manufacturers will need to meet ‘smart ready’ standards under new appliance regulations, including stricter rules on cybersecurity. Utilities will be obligated to ensure battery energy storage systems, heat pumps and electric vehicle smart charge points can work across different tariffs under tariff data framework.

MCS reports a record-breaking start to 2025 for certified heat pump installations, but the pace of deployment still falls short of 2028 targets. Subsidy support continues to drive heat pump adoption among UK consumers.

The Greenlink Interconnector comprises two high-voltage direct current (HVDC) cables reaching across the Irish Sea connecting the grids of Ireland and the United Kingdom at the Great Island substation in County Wexford and Pembroke substation in Pembrokeshire, Wales.

The European Commission has cleared a €400 million ($455.2 million) Spanish aid program to scale renewable hydrogen output, backing up to 345 MW of electrolyzer capacity and targeting 221,000 tons of production via the EU Hydrogen Bank’s 2025 auction round.

UK energy regulator Ofgem has approved connection queue reforms for Great Britain’s electricity grid. The change could see 65 GW of solar projects enter the fast-track “Gate 2” connections queue. The government claims reform will accelerate renewables and energy storage deployment while unlocking GBP 40 billion ($53 billion) of investment in clean energy and infrastructure.
