Australian researchers have analysed different ways to improve the efficiency of PV-powered water electrolysis for hydrogen generation. They include the use of magnetic fields, light energy, ultrasonic fields, and pulsating electric fields. Energy costs remain prohibitive, but molecular movement and the redistribution of molecules in water during electrolysis could open a path to viability.

Last year the Western Australian Government called for Expression of Interest into its potentially 1.5 GW solar and wind hydrogen hub at Oakajee Strategic Industrial Area on the state’s Mid-West. This week it has been revealed that 65 companies from around the world have submitted serious interest in making it happen.

The Federal Government has added a new element to the National Electricity Market (NEM) equation by announcing it will provide up to $11 million to help progress the CopperString 2.0 transmission project in Queensland.

The Australian Capital Territory Government continues its charge towards delivering big battery storage for Canberra’s energy grid with $100 million dedicated to provide at least 250 MW of large-scale battery storage.

Chemical engineers at the University of New South Wales and the University of Sydney have made a significant technological breakthrough in the development of green ammonia. The breakthrough could not only alter the global ammonia industry, but more easily use solar to produce green ammonia for export to countries like Japan and Germany instead of straight hydrogen.

Forget the beer goggles, settle into the spectacles of a sunny disposition and thank whatever gods may be for beer, solar panels and sunshine. That’s what Melbourne’s Moon Dog Brewing has done with the installation of a near 100 kW solar system atop their brewpub. Inspired by the savings made on emissions and electricity bills, the brewers have released a limited edition solar-powered IPA.

Hydro Tasmania and buyers Macquarie Group and ERM Power have signed a ‘Virtual Storage’ deal which will see the pumped-hydro company sell the rights to its highest priced periods of ‘discharge’ and buying a fixed MW block of low-priced ‘charge’. The innovative contract is the product of the ARENA-funded Renewable Energy Hub.

As the Smart Energy Council prepares to rollout the first pilot of its green hydrogen certification scheme, CEO John Grimes and consultant Scott Hamilton detailed the international discussions informing its architecture and what’s at stake for Australia’s export future.

Western Australia has seen around almost three quarters of its midday summer electricity demands being met by solar and wind generation in five of the past seven days.

Unlike other nations with more limited land and faster growing populations, Australia has not yet understood the symbiotic benefits which accrue when solar PV and agriculture are combined. This week, the Victorian Government announced its Horticulture Solar Energy program and $5 million in funding for the Tatura SmartFarm to experiment with solar atop a pear orchard.
