The Australian government’s green bank intends to move beyond solar and wind investment over the coming year and put its capital to work in the nascent green hydrogen industry and grid projects.

New Zealand researchers have proposed a way to assess the technical and economic feasibility of PV-powered parking machines. Solar might be an ideal solution, but the siting of the machines is critical and should be planned in advance, in line with available solar radiation and potential shading.

The Australian Energy Market Commission (AEMC) is calling for submissions on proposed rule changes that would address the integration of distributed energy resources, including enabling export charges as a pricing tool.

The Schools Virtual Power Plant pilot project, part of the WA Government’s $66.3 million investment in solar and batteries in its WA Recovery Plan from the impacts of Covid-19, will see ten schools transformed into VPPs. The two year trial is expected to bring reduced electricity bills to schools, improved grid stability, and increased solar uptake in the local community.

With the disruption of Covid-19 highlighting the climatic impact of the aviation industry, a recent report from the CSIRO funded by Boeing shows that hydrogen fuel’s technological momentum could see clean hydrogen used in airports by as early as 2025, and a full transition from conventional jet fuel by 2050.

COVID-19 has enhanced the conviction that Australia will benefit from advanced manufacturing and sovereign supply. Homegrown battery manufacturer Energy Renaissance is poised to drive home that advantage.

Neoen’s Hornsdale Power Reserve has gone to work in the first half of 2020, virtually tripling the French renewables developer’s storage revenue on comparative 2019 levels. However, this growth was largely caused by a one-off event, and a slower Q2 highlights the need for FCAS policy renewal. Neoen’s Australian solar revenues could also achieve little more than consistency thanks to poor conditions.

If it was designed with a focus on reliability, security and the lowest cost for consumers, Australia’s main electricity grid would see periods in which nearly 90% of demand is met by renewable generation. A diverse portfolio of distributed energy resources and large-scale solar and wind generation supported mainly by pumped hydro and batteries would ensure the least-cost transition as the nation’s coal plants retire. Adequate investment in transmission infrastructure will be instrumental in making this a reality.

Scientists in India have taken a close look at the potential impact of growing volumes of PV waste, and have conducted surveys that suggest a lot more work is needed from manufacturers and policymakers to develop management systems for end-of-life PV products.

A team of international researchers featuring ANU’s Prof Frank Jotzo has published a study on the ‘just transition’ from coal to renewable sources of energy. The paper looks at comparative examples of transitioning economies, taking account of political realities, and ultimately shows that a ‘just transition’ is just about the only transition worth having.
