The new material is not commercially available yet, but in trials the materials allegedly proved its technical and economical superiority over NMC 622, NMC 811 and NCA batteries.
The facility’s size and operational pattern could be optimized using a mixed-integer linear programming-based model. By selling hydrogen, supplying grid ancillary services and selling by-product oxygen, power-to-gas economics could be dramatically improved.
Researchers have matched the tinting of semi-transparent PV modules with the bandwidth of light that plants absorb for photosynthesis. A promising trial with basil and spinach has opened up economic opportunities for farmers.
Researchers have set out to study the kinetics of lithium deposition during cycling in a battery. By changing different parameters, they’ve found that it’s fairly easy to put lithium into amorphous form, which is superior on an electromechanical level.
Koen Peters has been the executive director of global offgrid solar association GOGLA since 2014. He has more than 20 years of international work experience, with more than 12 years in relation to energy access. He has gathered insights from many different perspectives and organizations, including government, consulting, startup businesses, and international finance organizations.
Inverter manufacturer Fimer provided its PVS980-58 central inverter solution for the project, which will derive 35% of its energy from solar PV.
In a little over ten years, Northvolt aims to pour 150 GWh of batteries onto the European market, annually. The company is also working to source end-of-life batteries for half its raw materials.
Scientists from the Institute of Electrical and Electronics Engineers have presented research suggesting a new topology for residential solar+storage inverters.
Canadian non-profit Plug’n Drive has looked at Ontario’s time-of-use electricity rates and found electric vehicle owners could generate substantial income by charging at night and selling to businesses during the daytime. Doing so could mean EVs have a lower net cost than conventional vehicles.
Kaco New Energy, STS Transformatoren Stockach, and Fraunhofer ISE have developed a new topology, management software, and transistors for hybrid inverters. Existing devices often suffer efficiency losses when power demand is low, as circuits and transistors are made to operate close to design specifications. The researchers claim their new tech could enable more battery use, based on simulation results.
