Field trial shows third-party control of residential heat pumps can provide grid flexibility
UK researchers find that smart, centrally controlled air-source heat pumps could slash peak electricity demand. The technology not only keeps homes comfortable but also boosts grid flexibility and cuts emissions.
Musk proposes PV-powered AI satellite network to fight global warming
Elon Musk says a constellation of solar-powered artificial intelligence satellites could regulate the planet’s energy balance and limit global warming.
AlphaESS launches all-in-one storage systems for C&I applications
Chinese energy storage manufacturer AlphaESS says its new Storion-H30-G3 and Storion-H50-G3 systems combine full integration, higher efficiency, and modular scalability to improve project safety and returns for commercial and industrial (C&I) users.
ZincFive unveils BC 2 AI battery system for both AI and traditional IT loads
The new nickel-zinc (NiZn) battery cabinet provides support for high-intensity AI pulses while also offering traditional IT backup within a compact footprint.
GSE Intégration debuts reversible, concrete-free solar mounting in France
GSE Intégration has introduced a new version of its ground-mounted photovoltaic structure, the GSE Ground System Evolution. It is designed for faster installation and compliance with France’s soil conservation laws.
Four-year testing finds heat pumps run efficiently even in older homes
Researchers at Fraunhofer ISE have tested various types of heat pumps in existing buildings across Germany over four years, finding that the systems achieved seasonal performance factors between 2.6 and 5.4. The team also showed that PV-driven heat pumps can boost self-consumption rates, particularly when paired with battery storage.
Florida utility on pace to reach 93 GW solar, 50 GW storage by 2045
While utilities in neighboring states are “dabbling” with solar, Florida Power & Light is combining solar and storage as a “workhorse” technology, said a nonprofit executive.
Europe faces surge in negative power prices as solar output grows
Sweden, the Netherlands, Germany, Spain, and France have each logged more than 500 hours of negative electricity prices this year, driven by excess renewable generation and volatile weather.
GoodWe debuts PV-driven heat pump water heaters
The Chinese manufacturer said their new residential heat pump water heaters deliver a coefficient of performance of up to 4.2, with a heating capacity ranging from 4.5 kW to 5 kW. The units are available with water tanks in 200 L, 300 L, and 500 L sizes.
France revises off-peak hours to match solar generation patterns
French grid operator Enedis will shift off-peak hours to daytime periods to align power demand with rising solar output and reduce evening consumption peaks.
