Scientists have used the US National Renewable Energy Laboratory’s (NREL) HOMER software to calculate the degradation of solar panels deployed in two rooftop PV systems operating in Germany since 2003. Their calculations focused on the energy productivity of the systems.

Lift Energy Storage Technology is a proposed long-term storage solution that relies on elevators to bring solid masses to the tops of buildings in charging mode. It then lowers the same mass to produce electricity in discharge mode.

Belgian materials company Umicore has signed a contract with Australia headquartered Vulcan Energy Resources to purchase up to 42,000 tons of lithium hydroxide over a five year period beginning in 2025. The material will be used in Umicore’s production of cathode materials for lithium-ion cell manufacturers.

Green Investment Group, owned by Macquarie, has launched Cero Generation, which will operate on a European scale and carry out both ground-mounted and commercial scale power generation projects. It will also provide integrated energy storage solutions.

Looking back over years of research into the topic of hybrid systems based on different combinations of solar, wind, hydro and other renewables, an international group of scientists found strong potential for strategies to exploit complementarity between the different sources integrate more intermittent renewables onto regional and national grids. The scientists present a series of conclusions and recommendations that aim to push research in hybrid renewables forward.
