Two of Australia’s most prominent energy players, Fortescue Future Industries and oil and gas giant Woodside Energy have been included on a shortlist of potential development partners for a proposed 600MW green hydrogen production and export facility planned for New Zealand’s South Island.

Renewable energy investors have again shattered the New South Wales Government’s expectations with more than 80 clean energy projects representing more than $100 billion of potential investment registering for the Hunter-Central Coast Renewable Energy Zone.

Conceived for the storage of residential and large scale renewable energy, the device has a rated power of over 150mW/cm2, an energy density exceeding 40Wh/L, and a power density of 72.5mW/cm2. The battery was built with an anode made of inexpensive viologen and its cost, according to its creators, may be lower than US$100/kWh (AU$140).

The Victorian government will be expanding its Solar Homes rebate program into the world of Virtual Power Plants (VPPs), announcing on Tuesday that households who install a battery and sign up to the pilot before July 2022 will receive a rebate of over $4000.

TOPCon solar modules will gain more market share if their average efficiency, already higher than that of PERC panels, continues to improve, according to Stefan Glunz, PV research chief at Germany’s Fraunhofer Institute for Solar Energy Systems ISE. In an upcoming pv magazine webinar on the potential of TOPCon tech, Glunz will show how to reduce costs and increase efficiency.

French start-up Rosi Solar has developed an industrial solution claimed to be capable of recovering high purity silicon, silver and copper contained in end-of-life PV modules. The company’s technology is based on a pyrolysis process that makes it possible to isolate the different metals from the cells.

U.S. company Verdagy has secured a US$25 million (AU$35 million) investment for its new electrolyser technology, which provides hydrogen fuel for heavy industrial applications. The membrane-based technology uses large active area cells, high current densities, and broad operating ranges to deliver hydrogen at scale.

The U.S. Department of Energy’s Ames Laboratory launched a new catalyst based on nitrogen and carbon to extract hydrogen from hydrogen storage materials at mild temperatures and under normal atmospheric conditions. Furthermore, South African President Cyril Ramaphosa said that the country is working on attracting new investments in electric vehicles and hydrogen and Norwegian consultancy and classification society DNV launched, together with 18 industry partners, a new Joint Industry Project (JIP) to enhance the standardisation for hydrogen production systems that use renewable energy-powered electrolysis to produce green hydrogen.

Western Australia will today introduce new curtailment rules which will allow for all new and upgraded solar PV and battery energy storage installations with an inverter capacity of 5 kW or less to be remotely turned down or switched off in emergency situations.

The proposed 1.5 GW Marinus Link transmission project, which would link Tasmania and the Australian mainland via an undersea electricity interconnector, has reached another milestone with the launch of a new engineering survey which aims to identify the most suitable corridor for the cables.
