Dutch startup stabilizes Netherlands’ grid with 9 MWh battery-flywheel storage facility
S4 Energy and ABB recently installed a hybrid battery-flywheel storage facility in the Netherlands. The project features a 10 MW battery system and a 3 MW flywheel system and can reportedly offer a levelized cost of storage ranging between €0.020 ($0.020)/kWh and €0.12/kWh.
H2X launches Warrego hydrogen-powered pickup truck
Australian startup H2X is finally launching its hydrogen-powered Warrego pickup truck, following the announcement of the fuel cell electric vehicle (FCEV) last year. It is now undergoing final validation and verification and will likely hit the market within nine months, according to the company.
How long do residential solar inverters last?
Multiple factors can affect the productive lifespan of a residential solar inverter. We take a look at solar inverters in the second part of our ongoing series.
New study shows impact of shading on PV cells
Scientists in China have studied the impact of shading on single solar cells and on simple arrangements of two cells connected in series or in parallel.
Hithium unveils 300 Ah battery for rooftop PV applications
Hithium’s new battery has an energy efficiency of 95% and an energy density of 170 Wh/kg. It can purportedly operate for more than 12,000 cycles.
Opto-electro-thermal model to predict solar cell temperature, output
French scientists have developed a fully coupled opto-electro-thermal model that reportedly predicts solar cell behavior under real operating conditions in a standalone framework. They said the model can detect the impact of cell doping on the operating temperature and the temperature coefficient.
Spanish gas supplier sets up hydrogen production for heating, residential hot water
Madrileña Red de Gas and Pryconsa are developing a green hydrogen project that will meet the energy needs of 100 homes in Madrid.
Super-fast, long-life aqueous rechargeable zinc battery
An international group of researchers has demonstrated an aqueous zinc battery with excellent performance in terms of capacity, rate capability, specific energy, and output voltage. The supercapacitor-battery hybrid device has also shown unprecedented cycling stability 99.2% capacity retention after 17,000 cycles at 100% depth of discharge.
Real barriers to virtual power plants
The technology is available for virtual power plants to be rolled out across the United States, argues Jigar Shah, the director of the Department of Energy’s Loan Programs Office. Their implementation could result in a cascade of benefits, including lower electricity costs and wider adoption of distributed energy resources like rooftop PV.
Short-term scarcity, long-term uncertainty weighing on green hydrogen
Historic analogues suggest that emergency-like policy measures could foster high growth rates, expediting a breakthrough and increasing the likelihood of future hydrogen availability. However, EU targets require unprecedented growth rates, according to a group of German and US researchers.
