Closed-loop pumped-hydro storage offers more chances to minimise environmental effects on water sources and overcomes the problem of finding suitable sites.

Rose Amal arrived in Australia from Indonesia 38 years ago to study at UNSW. Now her leadership and research are contributing to a new sustainable economy for Australia and clean fuels for energy-hungry industries.

PV’s contribution to a cleaner future can go well beyond generating emissions-free energy, but maximising the opportunity is not always straightforward. Ragna Schmidt-Haupt, partner at Everoze and a board member at Skyray, argues that investors and lenders have to start making decisions today to fulfil the required disclosure regulations and make sure their fleet has a positive impact on biodiversity. The key challenge is to weigh the techno-economic-ecological risks, opportunities, costs and revenues.

Australia’s clean energy transition is predicted to accelerate in the coming years with a new report suggesting most Australian homes and businesses will have switched to solar PV modules paired with batteries by 2030 while the nation will have the highest penetration of renewable energy per capita in the world.
