FREYR plans the Giga America lithium-ion battery manufacturing facility in Georgia
Leveraging SemiSolid battery technology from 24M Technologies, FREYR initially intends to produce 34 GWh with an investment of $1.7 billion.
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.
Sunrise brief: Florida Governor’s veto of net metering bill a win for clean energy in the Sunshine State
Also on the rise: Missouri town declares solar farm a nuisance. PG&E seeks 176 MW of front-of-the-meter local solar. Group using NREL’s free ReEDs model validates 100% renewables by 2035 for 24 states. Caesars bets on solar, breaks ground on three projects in Atlantic City. MIT, NREL researchers develop 40%-efficient thermophotovoltaic cell for grid-scale thermal batteries. SEIA cuts solar deployment forecast 46% in light of anti-circumvention investigation. LG Energy Solution Q1 net income cut in half by materials costs and supply chain challenges, with sights set on strong EV market.
MIT, NREL researchers develop 40%-efficient thermophotovoltaic cell for grid-scale thermal batteries
The device is described as a heat engine with no moving parts that is able to produce power from a heat source of between 1,900 to 2,400 C. This concept is known as thermal energy grid storage (TEGS) and consists of a low-cost, grid-scale storage technology that uses thermophotovoltaic cells to convert heat to electricity above 2,000 C.
Speeding perovskite solar cell development with machine learning
MIT and Stanford researchers are employing artificial intelligence to test perovskites in pursuit of a commercially viable PV cell manufacturing process.
MIT backed start-up develops polymer-based batteries for stationary storage
The device is based on a standard, two-electrode electrochemical cell containing conductive polymers, a carbon-graphene hybrid, and a non-flammable liquid electrolyte. The battery cells were tested to perform for 12,000 cycles at 100% depth of discharge.
MIT scientists develop PV cleaning system based on electrostatic repulsion
Scientists from the Massachusetts Institute of Technology have developed a system that can be operated at a voltage of around 12V, with a 95% recovery rate for lost power after cleaning. The waterless system can be operated automatically via an electric motor.
MIT and Google develop solar cell simulator
The differential physics-based software simulates how the change in a given input can change the cell’s power output, potentially paving the way for faster improvements in PV efficiency.
Recovering waste heat from solar cells using a thermoelectric generator
The device recovers waste heat from the PV unit and produces additional power.
Solar beach umbrella design cools you… and your gelato
An origami-inspired umbrella that can power a refrigerator was designed by an MIT-spawned innovation firm along with architects and an Italian frozen-desserts brand.
