Researchers in Canada designed an air-source heat pump integrated with an air-based solar collector and radiant floor heating for cold climates, showing that the proposed system configuratuon could improve the coefficient of performance from 2–4 to 2–6 and reduce significantly annual energy consumption.

ESS Tech is complementing its iron flow storage offering, which is engeeneered for the 8–24 hour long-duration segment, with sodium-ion battery products aimed at short and medium-duration applications.

The system features AI-driven energy management, 10,000-cycle battery life, and scalable expansion up to 126 kWh.

The first operational round of the EU Hydrogen Facility matched 265 supply-side opportunities with 45 demand projects, with 87% of offers receiving at least one expression of interest and half attracting multiple buyers.

The upcoming Solar Manufacturing USA 2026 conference in Austin will focus on real U.S. solar manufacturing progress, shifting attention from capacity announcements to actual production, costs, yields, and technology choices across the full value chain. It will also examine how policy changes and tariffs are driving domestic expansion in ingots, wafers, cells, and modules, while highlighting competing technologies like back contact, heterojunction and TOPCon.

Singapore’s Energy Market Authority (EMA) has made hydrogen readiness a mandatory requirement in a new request for proposals for at least 600 MW of gas-fired generation capacity, with proposals that do not meet cardinal requirements disqualified from evaluation.

While the exact specifications of the new product, such as dimensions and weight, haven’t been disclosed, available imagery suggests potential transportation challenges.

Researchers in Austria found that unusually high photovoltaic efficiency in lead-halide perovskites can be explained by internal electric fields generated at strain-induced domain walls, which separate charge carriers and enable long-range transport. Their experiments indicated that these effects arise from mesoscopic structural inhomogeneities rather than a uniform crystal structure, providing a general mechanism for charge separation in these materials.

Spain and Portugal are 53% less exposed to gas price volatility than they were three years ago, according to a new report from Positive Money.

Spanish researchers found that combining agrivoltaics with regulated deficit irrigation (RDI) can cut tomato irrigation water use by about 50%, while improving land-use efficiency through simultaneous crop and solar energy production.
