Energy Storage

A Chinese-Finnish research group has proposed the use of seasonal, soil-based thermal energy storage in combination with photovoltaics in residential districts. They have found that the hybrid concept could cover up to 58% of total heating demand.

The operator of the 150 MW/193 MWh Hornsdale Power Reserve in South Australia has been fined AUD 900,000 ($620,470) for failing to provide essential services to maintain the stability of the grid.

The California Public Utilities Commission has introduced a new rule to streamline the interconnection process for distributed energy resources.

Enerwhere has designed a solar-plus-storage mobile unit for offgrid locations such as oil and gas fields and construction sites. It can be adapted to different needs and is scalable up to megawatt-scale projects.

The Netherlands is planning a €1.5 billion ($1.6 billion) green hydrogen network that will consist of 85% recycled natural gas pipes. It is expected to go online in 2027.

Dutch researchers have developed a heat pump that can be used in combination with rooftop solar generation, due to its modulating capabilities and temperature flexibility. It measures 55 cm x 55 cm x 55 cm and has an output of 6 kW.

Renewable hardware that lasts longer and uses fewer materials could bolster recycling efforts and help to build an effective circular economy for solar and battery technologies, says the US National Renewable Energy Laboratory (NREL).

Researchers from the Indian Institute of Science, Bangalore, have found that nanoscopic refractory metal layers like tungsten could improve dendrite growth tolerance in electrolytes of solid-state Li-ion batteries. The team collaborated with researchers from Carnegie Mellon University.

A new report recommends a differential pricing mechanism for pumped-hydro energy storage (PHES) projects in pumping (off-peak operation) and generating mode (peak operation).

FAW Jiefang has completed a large fuel cell vehicle order in China, while chemical producer Linde has opened one of the world’s largest hydrogen refueling stations for trains. The European Investment Bank, meanwhile, has announced new funding for green hydrogen research in Italy.
