Australian coal plant tests iron flow batteries
Energy Storage Industries is delivering 1 MW/10 MWh of flow battery storage to the Stanwell Power Station in the Australian state of Queensland. The flow batteries are part of a new government-run clean energy testing “hub,” featuring hydrogen and additional workforce training programs.
The Hydrogen Stream: Hydrogen buses less efficient than battery models
Italian researchers have compared the performance of hydrogen and electric buses in northern Italy, while DNV has released its guidelines to validate claims related to low-carbon renewable hydrogen and ammonia attributes.
Scientists outline innovation pathways for PV technologies
Continued innovation in PV cell technology will have major impacts as PV is deployed at “multi-terawatt scale” over the next two decades, says a global team of scientists.
Foldable solar carport extends, retracts in response to weather
Switzerland’s Dhp Technology AG says it plans to deploy new retractable PV systems at 45 motorway service areas in the Swiss cantons of Valais and Bern. The foldable arrays can be retracted and protected during extreme weather conditions or hail storms.
Global polysilicon prices drop, China polysilicon prices rise
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Multi-day energy storage increases grid capacity by factor of 10
Form Energy has released a white paper that provides further evidence that multi-day energy storage, like its iron-air technology, can substantially reduce the costs for New York to achieve its ambitious decarbonization targets.
The Hydrogen Stream: Water splitting with solar-to-hydrogen efficiency of 12%
A Japanese team is working on a solar water splitting system with a 12% solar-to-hydrogen efficiency, while UK researchers have identified the reason why graphene’s dense crystalline structure is much more permeable to protons.
German consumer group debunks residential battery misconceptions
Verbraucherzentrale NRW, a German consumer protection association, has issued a warning about five misleading assumptions about PV-linked residential battery systems.
Monolithic perovskite-PERC tandem solar cell with 23.7% efficiency
Dutch scientists have developed a perovskite-PERC tandem solar cell based on a new type of tunnel recombination junction that reportedly offers an improved device efficiency distribution. The cell uses a nickel(II) oxide layer that is intended to reduce electrical shunts in the perovskite top cell.
Re:Build Manufacturing introduces solar ingot processor
Massachusetts-based Re:Build Manufacturing has unveiled the RBM600 Solar CZ Puller, a solar ingot processor designed to manufacture high-purity polysilicon ingots for solar panels.
