Over the last two years, corporate renewable power purchase agreements have become a major force in Australia’s large-scale renewable energy market. In hard figures, 70 leading Australian organizations have made the switch to renewable energy and procured nearly 2.3 GW of mostly solar and wind electricity and supported 5.2 GW of projects, finds the Business Renewables Centre of Australia.

Researchers from the University of Wollongong have manufactured a nanomaterial that acts as a superior cathode for room-temperature sodium-sulfur batteries, making them a more attractive proposition for large-scale energy storage.

From an energy-hungry importer to a frontrunner in the decarbonization race, South Australia has set the bar high for how to efficiently transition to a low-emissions grid dominated by renewables. With wind and solar already supplying more than a half of its electricity, the state’s energy transition shows no sign of letting up. In fact, South Australia is gearing up to accelerate the pace of its clean energy transition and expand its big PV fleet as it moves toward its 2030 target of “net” 100% renewables.

Swiss investment firm SUSI Partners is investing up to $50 million in a residential solar-plus-battery project enabling participants from communities across Western Australia to generate and consume their own clean power for up to 90% of their needs. The project, which began a year ago, and involves residents leasing solar PV and battery systems from a not-for-profit organisation.

Australia made its first moves to open up its energy industry in the 1990s, when the National Electricity Market (NEM) was first created, and many of the rules and regulations from back then are still in place today. But the rise of renewables in the 21st century, argues Clean Energy Investor Group Chair Rob Grant, necessitates a rethink of this market structure.

The Australian Energy Market Commission’s proposed transmission access model has come under fierce criticism from the clean energy industry for being unnecessarily complex and likely to increase the cost of capital for future generation and storage investment.

The New Zealand Rural Connectivity Group will use Redflow zinc-bromine flow batteries to store energy in off-grid telecommunication sites.

Utility-scale solar is booming in Australia. Quality assurance, especially solar panel testing, helps achieve better performance and lower costs. Best-practice testing is key, writes Michelle McCann, managing partner at PV Lab Australia, but must be planned and fully integrated into a project from an early stage. This integration ensures flow-through from panel manufacturers to commercial buyers and large project owners.

Fossil fuel giant Shell is set to make its foray into Australia’s electricity market after shareholders in electricity retailer ERM Power voted in favour of a $617 million takeover bid.

A result of a collaboration between global accounting and financial services firm KPMG, Canadian gas giant ATCO, Australia’s national science agency CSIRO and Australian Renewable Energy Agency (ARENA), H2City can be used to assess the costs and benefits of regional town or municipality switching to hydrogen.
