For every dollar invested in fossil fuels, 1.7 dollars are invested in clean technologies. Five years ago, it was a one-to-one ratio, said the International Energy Agency.

Despite their promise, adoption rates of Virtual Power Plants (VPPs) in Australia have been underwhelming. Head of Renewable Energy Finance at Plenti, Louis Edwards, says the issue stems from VPP operator’s overlooking their point of sale. “It’s too much risk the installer takes and they don’t do it,” he tells pv magazine Australia.

About 70 Katahdin breed sheep were dropped off at the Oberlin College campus in Ohio last week. They will graze through mid-June, stomping grass and weeding the solar field in a move aimed at reducing operations and maintenance costs.

An international research team in China has used Czochralski n-type c-Si wafers from China-based Sichuan Yongxiang to build textured wafers with a thickness ranging from 65 μm to 55 μm. They have used the wafers in heterojunction solar cells ton hit efficiencies close to those of devices cells based on conventional wafers.

Queensland has opened its first Queensland SuperGrid Training Centre and Transmission Hub in Gladstone. The facility is expected to train 500 energy workers annually in a range of areas, including high voltage technical training.

GemLife, which describes itself as “luxury resort living for the over-50s,” has set up its own Virtual Power Plant (VPP), and is set to invest $75 million in coming years to rollout the VPPs across more than 10,000 homes in its property portfolio on Australia’s east coast.

Queensland flow battery company, Redflow, has commissioned a 30 kWh zinc-bromine flow battery for the Brisbane City Council.

A new study by the University of Hohenheim shows that shading from PV systems can improve agricultural yields, especially in dry periods, but additional research is needed.

Australia’s national science agency will seek to the address some of the challenges associated with storing and transporting hydrogen by developing an off-grid, portable hydrogen generator designed to recover the zero-emissions fuel from a liquid carrier at the point of consumption.

The Victorian government has signed off on a preferred development plan for the contentious VNI West transmission project that will connect the Victorian and New South Wales electricity grids and promises to unlock upwards of 3.4 GW of new renewable generation capacity.
