UK-based researchers have developed a novel method to estimate the amount of defrost cycles a heat pump will experience in the winter and how much energy it would require to implement the cycles. The results of their simulation showed a strong relationship between the number of defrost cycles and the ambient temperature.

Swedish battery maker Northvolt has developed its first sodium-ion battery in partnership with Uppsala University spinoff Altris. The cell has been validated for an energy density of more than 160 Wh/kg and is designed primarily for energy storage applications.

Statkraft used actual production data from wind and solar farms in Spain to study the feasibility and bankability of hydrogen projects. For a 1 MW electrolyzer to achieve a 40% utilization rate, five times more solar capacity would be needed, it said.

Epishine, an organic PV module manufacturer, has completed a new factory in Linköping, Sweden. The facility uses roll-to-roll equipment to produce new products for low-power battery replacement and the self-powered electronics market.

Andries Wantenaar, a solar analyst at Rethink Energy, explains why he sees a bright future for perovskite PV cells, with technological advancements and major R&D investment paving the way for revolutionary change.

A group of scientists across the world have created a list of recommendations that can help create solar neighborhoods. In a recently published study they highlight the importance of legislative frameworks and advanced computing.

Neoen and Alight have started building the 100 MW Hultsfred solar farm in Sweden, which will purportedly be the country’s largest solar installation upon completion.

Sweden-based Epishine has launched a developer kit based on its 6-cell 50 mm x 50 mm organic PV module for prototyping and testing its use in battery-free indoor sensing and monitoring devices.

The US Department of Energy has allocated $7 billion for seven Regional Clean Hydrogen Hubs (H2Hubs) to deploy commercial-scale clean hydrogen, while the Mission Possible Partnership, RMI, Systemiq, Power2X, and industry leaders have set up the Transatlantic Clean Hydrogen Trade Coalition (H2TC) to ship US clean hydrogen to Europe by 2026.

Northvolt says it will use a circular economy approach to achieve 60 GW/h of annual cell production in Quebec, Canada, with a focus on assembling batteries for the US automotive market.
