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.
The Hydrogen Stream: What the EU’s Fit for 55 means for hydrogen
The revision of the EU Energy Taxation Directive (ETD) and the Renewable Energy Directive (RED) will also have an impact on the nascent hydrogen economy. The European Commission is currently evaluating options to create a certification system for low-carbon fuels and it may extend the EU-wide certification for renewable fuels to include hydrogen.
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.
Australian state approves 600 MW solar+battery project
The authorities in New South Wales have approved a massive solar+storage project, paving the way for construction to start in the Australian state next year.
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.
What is needed to persuade UK households and businesses to go solar?
The government’s Department for Business, Energy and Industrial Strategy surveyed householders and small businesses and was told the prospect of firms having to pay higher taxes after installing PV prompted fury – just as the national solar trade body has been telling Whitehall for years.
