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.
New battery chemistry tweak could double EV range
Researchers at the Pacific Northwest National Laboratory have developed a revolutionary lithium-metal battery chemistry that could allow electric vehicle batteries to almost double their capacity, while also overcoming historic setbacks.
Hydrogen-fired gas turbines vs. lithium-ion storage
According to a new study from the Massachusetts Institute of Technology, hydrogen-fired gas plants will compete with lithium-ion storage for seasonal storage and their competitiveness will strictly depend on the heat rate of the gas power plants they may replace.
