Australia’s biggest battery starts commercial operations
The first stage of the biggest approved battery project in Australia is now fully operational with Origin Energy announcing the initial stage of the 700 MW / 3,160 MWh battery energy storage system being built next to its Eraring coal-fired generator in New South Wales has commenced commercial operations.
UK startup claims its electrolytes can triple flow battery energy density
A startup led by Cambridge University scientists and the former chair of Oxford PV is attempting to commercialize flow battery electrolytes with greater energy density than vanadium-based batteries. Kodiaq Technologies claims its electrolytes can be deployed as a drop-in solution for redox flow batteries.
Quilt launches 3-zone ductless heat pump for residential applications
U.S. startup Quilt has introduced a new three-zone ductless heat pump for residential use, offering independent temperature control across three areas with a single outdoor unit. The system uses R32 (difluoromethane) as the refrigerant and can reportedly achieved a coefficient of performance of 4.2 at 8 C.
New European solid-state battery business targets commercial production
Axen, Syensqo and IFPEN establish new company to produce high performance sulfide solid electrolytes for solid-state batteries in Europe. New company Argylium will develop its electrolyte portfolio at facilities in France.
Australia adds 1.2 GWh of behind-the-meter battery storage in December
More than 1.2 GWh of new behind-the-meter energy storage capacity was installed across Australia in December 2025 as households and businesses sought to take advantage of the federal government’s revised AUD 7.2 billion ($4.9 billion) Cheaper Home Batteries Program.
