Energy Storage

Italian researchers have reviewed different system configurations for photovoltaic-thermal solar-assisted heat pumps in buildings. They say that using the PV-thermal collector as the heat pump’s evaporator results in the highest heat recovery, but a dual-source system with a separate heat exchanger is the most promising solution to cover all thermal needs.

Australian scientists have developed a new way to make hydrogen directly from seawater. They have described the technology as a critical step to a truly viable green hydrogen industry.

RoyPow introduced a new residential lithium-ferro-phosphate battery this week at Intersolar North America in Long Beach, California.

Researchers in China have successfully prepared cobalt oxide-modified graphite felt as an electrode material for an iron-chromium flow battery. The electrode performance significantly improved due to the effects of cobalt, which in turn boosted the energy efficiency and overall performance of the battery.

SolarEdge’s revenue rose 58% year over year to $3.1 billion in 2022. It expects revenues for the first quarter of 2023 to be within the range of $915 million to $945 million.

The University of California, Merced, has shown that up to 13 GW of solar capacity could be installed over California’s canals, which would require approximately 3 GW of energy storage.

There is currently no widely accepted test methodology to assess the safety of second-life lithium-ion batteries (LiBs). However, a UK government study reveals two opposing views on their safety, raising concerns over whether such devices should be deployed in homes under any circumstances.

Joachim Steenstrup, head of public affairs for Denmark-based Eurowind Energy, speaks to pv magazine about hybrid solar-wind projects, why the hybridization trend makes financial sense, and how PV-wind hybrid installations are the building blocks for the “energy centers” of the future.

The European Commission has presented the final version of its new rules for green hydrogen, with looser requirements to qualify hydrogen as “green.”

Researchers in Germany have assessed direct coupling and integration between PV and batteries at the scale of a single PV module. They say their solution could be cheaper and provide superior performance than maximum power point tracking (MPPT) in optimizing PV system performance.
