The global battery energy storage market will grow to US$10.84 billion (AU$14.54 billion) in 2026, with around two-thirds of the demand concentrated in the Asia Pacific region.

Solar data company Solargis has released 10-year solar performance maps showing Australia’s massive variations in irradiance and the impacts of extreme weather patterns and events.

A group of international scientists has investigated the potential use of radiative cooling in PV systems, in a newly published review focusing on challenges and opportunities for the passive cooling technology.

In other news, GM and Honda are jointly developing affordable EVs, the Biden administration holds an EV industry meeting, and Mercedes-Benz Energy agrees to supply EV batteries to BatteryLoop for its scalable, circular energy storage products.

US scientists have developed a battery that can retain 92% of its initial capacity over periods of 12 weeks, with a theoretical energy density of 260W/hour per kg. It was built with an aluminium anode and a nickel cathode, immersed in molten-salt electrolyte.

UK-based analyst Exawatt and Germany’s Nexwafe published a white paper this week that takes a close look at the current state of PV manufacturing worldwide, and how Nexwafe’s innovative wafer production tech might fit into it. They said that if the potential of its Epiwafer can be realised, the PV industry may yet see “another revolution in wafer manufacturing.”

Hertz, one of Australia and indeed the world’s biggest car rental companies, has announced it will be adding up to 65,000 new electric vehicles (EVs) to its fleet. While the percentage of those bound for Australia is still being negotiated, it adds to the rapid growth of our EV market – albeit from a low baseline.

Photovoltaics can wipe out 4.25 billion tonnes of carbon emissions every year this decade, according to the UN Intergovernmental Panel on Climate Change. Even so, the actions announced so far remain way short of what is needed, with capital flows to fossil fuels still greater than the cash directed toward combating climate change.

The result was confirmed by the National Institute of Metrology of China. It was achieved with a cell size of 210x210mm.

The Berlin Energy Transition Dialogue 2022 event has shown the centrality of renewables and green hydrogen in the world’s future energy landscape. pv magazine spoke with the General Director of the International Renewable Energy Agency, Francesco La Camera, about the difficulties of creating a hydrogen economy in the absence of demand. According to him, public support and policies will be crucial to overcoming this challenge.
