Unlimited low-cost energy storage
In its latest monthly for pv magazine, the International Solar Energy Society (ISES) explains how pumped-hydro energy storage combined with PV power generation could provide 24/7 power to data centers. From pv magazine Global Pumped Hydro Energy Storage (PHES) provides a vastly available, highly mature, lowest-cost, lowest-impact, longest-lifetime solution to dunkelflaute. PHES constitutes 95% of […]
Residential geothermal systems positioned to save energy for new construction projects
Dandelion Energy CEO says OBBBA provisions open new pathways to make geothermal more accessible and affordable. The One Big Beautiful Bill Act (OBBBA) is widely perceived as a setback for renewable energy, particularly in combination with executive orders from the Trump administration placing additional restrictions on solar and wind. While solar developers are looking to […]
Geothermal developer Mazama Energy aims for 5¢/kWh power
Mazama Energy says it has accessed a world-record high temperature geothermal resource, and that hotter underground rocks can enable lower-cost power. Mazama Energy has reported that its pilot enhanced geothermal project in Newberry, Oregon has reached a “bottomhole” temperature of 629° F, which it says is a world record high temperature. The higher temperature “marks […]
New York awards $7 million for co-located solar and farming
Grant funds were administered by the New York State Energy Research and Development Authority (NYSERDA) to demonstrate the efficacy of agrivoltaics. Agrivoltaics, the practice of installing solar arrays raised above crops or livestock, is gaining interest nationwide as a solution to boost clean energy generation while not compromising productive farmland. The New York State Energy Research […]

The company announced a partnership with Infineon to produce solid-state transformers designed to power AI datacenters. SolarEdge Technologies announced its Q3 2025 earnings, posting a third consecutive quarter of revenue growth and increased margins. The company’s stock price (Nasdaq: SEDG) is up over 25% in […]
Protecting the grid from extreme weather
IEC Standards help to make the grid more resilient as the impact of climate change intensifies. From pv magazine Global The electricity grid is expected to be increasingly affected by climate change and the resulting severe weather episodes, which are predicted to multiply as our world heats up. Fires, floods, hurricanes and even extreme heatwaves […]
Researchers discover photovoltaic properties in zinc-based film
Research from the University of Wisconsin-Milwaukee has found zinc-phosphate-hydrate (ZPH) films are capable of producing electricity from light. The coating’s photovoltage was amplified when anthocyanin, a natural dye found in blackberries, was added. From pv magazine Global A research team at the University of Wisconsin-Milwaukee (UWM) has discovered that zinc-phosphate-hydrate (ZPH) films coated onto metals […]
Scientists break Shockley-Queisser efficiency limit for silicon solar cell in experiment
A Chinese-US research group claims to have achieved a power conversion efficiency of over 50% in an n-type single-junction solar cell by inhibiting light conversion to heat at extremely low temperatures. The result was achieved at temperatures of 30-50 Kelvin, which are a few tens of degrees above absolute zero. From pv magazine Global Researchers […]
New control strategy for grid-forming inverters
Researchers in the United States have created a droop control strategy for grid-forming inverters that purportedly improves power system frequency stability. By using an exponential active power–frequency relationship, the novel technique optimizes the use of available headroom, reduces frequency deviations, and enhances overall grid resilience. Renewable energy resources using grid-forming inverters can actively regulate voltage […]
NREL researchers address safety implications of next-generation battery technologies
Report says new evaluation methods, including AI, will help make future batteries safer. If lithium-ion batteries were once viewed as an expensive energy storage solution with tenuous supply chains, mass production has made them both affordable and readily available for a wide variety of applications. Consumer electronics, electric vehicles and, importantly, battery-based energy storage systems […]
