The prospects for solar in a 1.5C world
We will need 10.7 TW of clean energy generation capacity this decade to stay on track with the most ambitious of the climate change paths agreed in Paris, which would include plenty of solar investment and jobs, according to the International Renewable Energy Agency.
Storage solution takes batteries back to basics
Urban Electric Power has been accepted into EPRI’s Incubatenergy Labs program to prove the value of its new battery tech to some of the top utilities in the United States.
New cathode design promises battery sustainability
Scientists in the U.S. developed a new cathode design for lithium-ion batteries that they say could open up a range of different materials for further research. The group has high hopes that the discovery can quickly be brought to scale, easing some of the growing concerns around supply chains for battery materials.
Sulphur-based redox flow battery with 15 consecutive hours of runtime
Researchers from Hong Kong have applied a novel charge-reinforced, ion-selective (CRIS) membrane to a polysulfide-iodide redox flow battery they had built in 2016. The redox flow battery showed a capacity decay rate of just 0.005% per day for 1,200 cycles, and a lifetime with over 2,000 hours’ cycling, which the academics said corresponds to approximately three months.
Arevon opens 100 MW/400 MWh storage facility in California
Arevon’s new project in California uses 142 Megapacks, which is Tesla’s utility-scale battery storage product.
Solar+storage kits for construction sites, one-off events
France’s Revolt Energy Green has developed a flexible solar+storage solution for one-off events, construction sites, and different kinds of off-grid applications. It has also developed a mobile hydrogen solution.
Kehua unveils high-voltage battery for residential applications
The device has a maximum power output of 6 kW and a storage capacity of 8.2 kWh. The product comes with IP65 protection and its operation is guaranteed for 10,000 cycles.
India’s NTPC launches tender for 1 GWh of grid scale storage
State-run power producer NTPC has more than 65 GW of installed capacity, including gas, coal, hydro, and renewables-based power stations.
Storing solar power with recycled batteries from Nissan
Acciona is testing four second-life batteries with a combined capacity of 130 kWh at its 1.2 MW experimental solar park in Tudela, in the Spanish region of Navarra.
New microinverter from the US
Yotta Energy’s new micro-inverter is claimed to be an ideal solution for commercial rooftop PV systems linked to between 500 kWh and 1 MWh of storage. The device has a peak efficiency of 96.5% and a nominal maximum power point tracking (MPPT) efficiency of 99.5%.
