Aluminum-sulfur battery for small-scale storage at $8.99/kWh
Massachusetts Institute of Technology researchers have developed a battery with two electrodes made of aluminum and sulfur, and a molten salt electrolyte placed between them. They said the sulfur electrodes with a high loading of 12.0 mg cm2 can sustain a high capacity of 520 mAh g–1 over 100 cycles at 5 C.
GAF Energy breaks ground on US solar roofing factory
GAF Energy said its new production facility in Georgetown, Texas, will create hundreds of renewable energy jobs.
Predicting solar power output with limited data sizes
Researchers in Greece have developed three different transfer-learning strategies for solar power forecasting. The techniques are based on a stacked long short-term memory model, which is a kind of recurrent neural network that can learn order dependence in sequence prediction problems.
Sri Lanka launches tender for 100 MW solar park
The Sri Lankan authorities are seeking a developer to build a 100 MW solar project on a build-own-operate basis, in addition to a new 132 kV transmission line. The facility will sell power to the Ceylon Electricity Board under a 20-year power purchase agreement.
