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.
The Hydrogen Stream: EU auction attracts 132 bids for 8.5 GW electrolyzer capacity
The European Hydrogen Bank’s pilot auction has drawn 132 bids, exceeding the available budget, while Australia has finalized an agreement to build a hydrogen hub.
Panasonic presents air-to-water reversible heat pumps
The Japanese electronics manufacturer said its new heat pumps are suitable for commercial, industrial, and multi-dwelling residential applications. The new products feature a rated power ranging from 50 kW to 80 kW and a coefficient of performance spanning from 3.2 to 3.4.
Sharp unveils vehicle-to-home EV charger for PV-powered homes
Sharp has developed vehicle-to-home (V2H) electric-vehicle chargers for PV-powered homes, featuring 6 kW of charging/discharging rated power and an input DC voltage of 340 V. The wall-mounted devices are suitable for indoor and outdoor environments.
Simulation model to determine coefficient of performance of air-source heat pumps
A Dutch research team has outlined a new method to assess the coefficient of performance of air-to-water heat pumps by considering ambient temperature and relative humidity. The model is based on the equalization of the so-called logarithmic mean temperature difference (LMTD), which determines the temperature driving force for heat transfer in flow systems such as heat exchangers.
