Norway based renewables investor Magnora has increased its stake in startup equipment supplier Evolar, which is aiming to bring a production line for perovskite solar cells to market. Magnora will now hold a 40.7% stake in the company as part of a long-term deal between the two, with options to further increase the stake available down the line.

A prototype of a cement-based battery has been developed in Sweden for potential applications in buildings. Its creators claim it could become a solution to store electricity from rooftop PV and they do not exclude that it could also be used for the storage of large-scale renewables.

The Swedish company secured $38 million to build a manufacturing facility it has planned with the support of Swiss conglomerate ABB. The factory will be located in Stockholm and produce the company’s Powerfoyle products.

Developed by Swedish scientists, the proposed algorithm is said to calculate a project’s ideal design by combining climatological data with figures on expected solar power generation, shading distribution, water for irrigation, and agricultural yield. Its creators spoke with pv magazine about the key parameters that the model seeks to determine, one of which is the optimal distance between the solar module rows depending on the kind of crop.

The new budget will be devoted to private individuals only. The Swedish Energy Agency has so far devoted around $570 million to the solar rebate program, for the 2009-21 period.

Vattenfall, SSAB and LKAB are building a rock cavern storage facility in a coastal city in northern Sweden. The 100-cubic-meter facility will be built 30 meters below ground and will begin storing green hydrogen next year.

The Scandinavian country saw the installation of more than 400 MW of PV systems last year. The Swedish solar market keeps being driven by rooftop PV.

A new type of carbon fiber and electrolyte matrix stunned scientists when they tested its properties. Their ‘structural’ battery could be used in electric vehicles and could even address the weight problems that bedevil devices planned for electric-powered flight.

The technology developed by a business spun out of Stanford five years ago could deliver an electrolyte with energy density of more than 1 kWh/l.

Lithium-ion batteries can not only improve self-consumption in commercial PV systems but are also able to efficiently perform peak shaving and price arbitrage, according to an international research group which has proposed a new strategy to calculate the best system configuration in terms of costs and revenue. The scientists specified, however, that the novel strategy may become effective only if storage system prices will drop under $250/kWh.
