Researchers in China have built a PV-powered air conditioner that can store power through ice thermal storage. The performance of the system was evaluated considering operating efficiency and stability and the scientists found that a device relying on a variable-speed compressor and an MPPT controller showed very good ice-making capability.

Spanish renewable energy company Acciona is testing four second-life batteries with a combined capacity of 130 kWh at its 1.2 MW experimental solar park in Tudela, in the Spanish region of Navarra.

The contentious two-way pricing reform proposed by the AEMC, dubbed the ‘sun tax’, is based on the understanding that solar is a plaything of the rich. In fact, the inverse may be true, according to a new paper published by the Victoria Energy Policy Centre. But Vinnies’ research manager Gavin Dufty, an instigator of the rule change, told pv magazine Australia such analysis misses the point, branding it ‘myopic’.

Rice University engineers produced “near-perfect” 2D perovskite crystals for photovoltaic applications, grown from seeds.

A French start-up has developed a concrete flywheel to store solar energy in an innovative way. Currently being tested in France, the storage solution will be initially offered in France’s overseas territories and Africa.

The Gladstone Energy and Ammonia Project plans to efficiently use available resources and technology to produce low-cost, relatively low-emissions blue hydrogen from coal, and provide a conduit to commercialising true green hydrogen. A federal emissions policy driving toward a net-zero commitment could properly value GEAP’s place in Australia’s energy and export ecosystem.

The first new ISS Roll-Out Solar Array (iROSA) has been installed on the International Space Station.

Western Australia utility Horizon Power has achieved a major milestone with the coastal town of Onslow powered 100% by solar PV and battery during a successful trial of what is one of Australia’s largest distributed energy resource microgrids.

Wood MacKenzie’s energy transition modelling is predicting a primacy in the future low-carbon hydrogen economy for Australia. Thanks to the country’s solar irradiance and renewable energy expertise, as well as its relative proximity to major off-taker markets, Australia could be looking at export revenues of up to US$90 billion by 2050.

The Australian Energy Market Operator’s latest analysis of the Western Australian Wholesale Energy Market has found that investment in renewable generation and distributed solar is accelerating at a rapid pace, and importantly, that that acceleration is within the control of the state’s energy transition strategies.
