Israel-based Augwind has built its first 250 kW/1 MWh compressed air storage system for the collective community of Yahel, in the southern, desert part of the country. The commercial scale facility will be connected to a PV system and will be used for behind-the-meter services.

The ability of grid-scale batteries to provide fast frequency response and synthetic inertia services to the National Energy Market will be put to the test with infrastructure service provider Lumea confirming commissioning of the 50 MW/75 MWh Wallgrove Grid Battery in Western Sydney has commenced.

Some 90,000 individual solar panels will generate enough electricity to cover around 40% of the electricity used in two buildings for Google.

A number of Australian battery material recovery projects got off the ground this week, including the completion of Western Australian outfit Neometal’s battery recycling demonstration plant, a Queensland-Japanese joint venture studying the extraction of cobalt from copper tailings as well as the funding of Sydney-based startup Novalith.

Three companies are swapping out aluminium and glass in favour of plastic to save weight and add flexibility. We look at the pros and cons.

U.K.-based Gravitricity is planning to deploy its gravity-based energy storage solution at a decommissioned coal mine in Czechia. The project is part of a plan to commence a full-scale, 4-8 MW prototype scheme in a disused mine next year.

The record efficiency was obtained thanks to an interlayer placed between the electron-transporting layer and the perovskite layer, which eliminated the need for passivation. The cell was also able to retain around 90% of its initial efficiency after 500 hours under standard illumination.

One year on from its spinoff from SunPower, cell and module maker Maxeon Solar Technologies is looking to supply both “across and through” the solar market segments in the Asia-Pacific region. Chris O’Brien, the vice president of APAC for Maxeon, says that the region is set to grow in importance among PV marketplaces, with opportunities on the home, business and free field.

Queensland government-owned utility Ergon Energy has opened the doors to a new $6 million “world-class” research and development hub designed to accelerate the integration of renewable energy technology including microgrids and standalone power systems into the state’s electricity network.

Australian clean energy investment firm Providence Asset Group will roll out hydrogen-lithium battery technology at its solar farms after partnering with the Commonwealth Bank to fund a portfolio of 10 community-based solar plants in regional Victoria as part of the group’s larger ambitions to develop up to 40 ~5 MW solar farms across the eastern states.
