Storing renewables with high-rise elevators

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.

New water-draining device for rooftop PV systems

Portuguese startup Solarud has developed a way to eliminate soiling around the frames of PV panels with low inclination slopes. The device drains water that would otherwise stay stagnant on the surface of modules.

Energy Vault signs deal with India for gravity-based energy storage

Switzerland’s Energy Vault will support Indian state-run power producer NTPC by deploying its gravity-based energy storage technology and software solutions.

Long-duration storage solution based on saltwater

Developed by Dutch start-up AquaBattery, the storage technology is claimed to independently amend power and energy capacity. The battery system utilises three storage tanks, one with fresh water, one with concentrated salt water and one with diluted salt water, and also relies on membrane stacks.

European Commission could call in Australian investor Macquarie’s bid for French developer

Australia’s Macquarie is leading a consortium that has reportedly tabled a €2.5 billion ($3.65 billion) bid for a clean energy business formed by French private equity houses InfraVia and Eurazeo.

Molecular thermal energy system can store solar energy for 18 years

Developed by a Chinese-Swedish research group, the device is an ultra-thin chip that could be integrated into electronics such as headphones, smartwatches and telephones. It combines a Molecular Solar Thermal Energy Storage System (MOST) with a micro-fabricated system that includes a thermoelectric generator (TEG) with a low-dimensional material-based microelectromechanical system (MEMS).

Reinhart-backed WA company to supply Germany with geothermal heat before turning to lithium extraction

West Australian company Vulcan Energy Resources, backed by mining magnate Gina Rinehart, has signed a geothermal heat energy offtake agreement with a major German energy supplier, MVV Energie. Vulcan is planning to eventually secure a lithium supply from the same deep brine source in the Upper Rhine Valley, Germany.

CO2 battery long-duration energy storage technology wins BNEF Pioneers 2022 competition

Energy Dome’s emission-free energy storage method uses carbon dioxide in a closed loop charge/discharge cycle that can store and dispatch renewable energy onto the grid over periods from four to 24 hours.

UK government warns of global warming risks related to hydrogen leaks

The UK Department for Business, Energy and Industrial Strategy has published new research showing that hydrogen leaks could have an indirect climate-warming impact, partly offsetting efforts to reduce carbon dioxide emissions.
