Storing solar power via borehole thermal 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.
Tesla big battery operator fined for breaching Australian power rules
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.
Netherlands to build 10 GW national network for green hydrogen
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.
Indian researchers develop tech to stop dendrites in solid-state lithium batteries
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.
New pricing mechanism for pumped-hydro storage in India
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).
Lithium-ion fire fears spark recall of 433,000 solar LED umbrellas in US, Canada
The US Consumer Product Safety Commission and Health Canada have issued a joint recall of patio umbrellas due to fires caused by the overheating of lithium-ion batteries.
Decentralized plant to convert ammonia into hydrogen
Spain’s Tecnalia is developing a facility that will provide provide clean fuel for a hydrogen bus fleet in Birmingham, England.
Four-mode hydrogen plant to accommodate renewables
Bio-FlexGen, an EU research project, seeks to develop a combined heat and power plant (CHP) system with hourly, daily and seasonal flexibility via hydrogen production from biomass.
Photon-enhanched rechargeable batteries for solar storage
Japanese scientists have analyzed storage systems that combine PV and high-energy-density metal batteries. The rechargeable batteries have advantages such as low-charge voltage and high energy density, but stability and safety must be addressed before they reach commercial maturity.
Sun Cable project secures support of Infrastructure Australia
Sun Cable’s massive AUD 30 billion ($20.7 billion) Australia-Asia PowerLink project has passed another major milestone by obtaining approval from Infrastructure Australia.
