US start-up unveils 3.6 kWh portable battery for independent power supply
The system can be expanded to a capacity of up to 25 kW. Its creator – U.S.-based start-up EcoFlow – has already collected almost €4 million on the Kickstarter crowdfunding platform for its portable power supply solution.
Heat pumps bankable as incentive-free solutions in many applications
Two Italian experts on heat pumps and PV systems recently spoke to pv magazine about economies of scale, the European market, and the maturity of heating tech. The Eurac researchers said currently available heat pumps can run at -20 C and efficiently provide hot water up to 65 C.
Storage, curtailment could support 130 GW of PV in Italy by 2060
A group of scientists argue that centrally managed, flexible PV fleets could be an optimal solution for Italy. And they claim that a mix of storage and curtailment could facilitate the deployment of 130 GW of PV by 2060 at a minimal cost.
Australian utility tests compressed air storage
Compressed air energy storage is not exactly a new technology, but recent months have seen it get a new lease on life, as intermittent renewable sources of energy come to the fore.
Hold your breath for a better battery
Recent research has revealed a previously underestimated role for oxygen in limiting the performance of lithium-ion batteries. Newly published research from both Japan and the United States has sought to look deeper into the chemical reactions at the heart of lithium-ion storage; and to better characterize the cumulative effects that minuscule amounts of oxygen released during these reactions can have on battery performance and safety.
German start-up offers 5.2 kWh AC battery that works without inverter
Sax Power has developed a new residential battery which it describes as a game-changer in the battery technology.
New residential lithium-ion battery from Germany
The battery system, which is aimed at increased self-consumption, can handle a maximum DC input power of 18 kW and 1000 V.
China wants to test vanadium redox flow batteries
A 125 kW/500kWh storage unit will be tested by China’s National Photovoltaic and Energy Demonstration Experimental Center. The storage system will be provided by Canadian specialist VRB Energy.
Sonnen battery still running after 28,000 full charge cycles
Sonnen has published test results indicating the longevity of its storage systems after extended use.
‘Fit for 55’ could be fit for 660 GW of solar this decade
While trade group SolarPower Europe has welcomed the EU’s emissions-reduction legislative package, it renewed calls for solar and energy storage to be mandated on buildings and urged policymakers to go even further than the stated ambition for clean power to fire 40% of European electricity by 2030.
