Global atlas for pumped hydro at mining sites
The researchers that created the atlas considered mining pits, pit lakes and tailings ponds within mining sites and located nearby reservoirs. The selected sites have a potential storage capacity of 30 TWh.
Energy Vault starts building green hydrogen storage project
Energy Vault has begun construction on a 293 MWh green hydrogen and battery storage facility within utility Pacific Gas & Electric’s service territory in northern California.
PVT-assisted heat pump for residential water heating
A group of scientists in China has designed a residential heat pump system with a potential cofficient of performance of 4.271 at -5 C. The system is reportedly able to adjust the required pressures based on solar irradiance intensity and ambient temperature
Australian state awards permit for 1.3 GW pumped hydro station
Former Australian Prime Minister Malcolm Turnbull has secured a contract to develop two large-scale pumped hydro projects on water reservoirs owned by the New South Wales government.
The Hydrogen Stream: Luxury regions invest in marine hydrogen services
SBM Offshore has installed a floating facility in Monaco to produce green hydrogen from renewables, while Axpo and its partners have revealed plans to use hydrogen to power a passenger vessel in Switzerland.
Australian researchers develop magnesium-ion water battery
Australian scientists claim that the process of manufacturing magnesium-ion water batteries indicates that mass production is feasible, given that materials such as magnesium and zinc are abundant in nature.
Swedish virtual power plant software developer secures funding
Swedish virtual power plant software platform developer Fever Energy is expanding into Europe enabled by a $10.81 million round of venture capital.
UK researchers identify optimal heat pump design minimizing system transition costs
Researchers led by the Imperial College London have analyzed the effects different kinds of air-to-water heat pumps will have on the UK energy system, based on their coefficient of performance and price. They also identified a point of diminishing returns, after which it is more cost-effective to invest in centralized energy generation and storage.
Rheem presents residential heat pump
The heat pump uses R-410a as a refrigerant and has a size ranging from 2 tons to 5 tons or 7.0 kW to 17.6 kW. It also has a cooling capacity spanning from 6.7 kW to 15.5 kW.
