Swedish researchers have analyzed the impact of electric aviation and electric vehicle (EV) charging on the power system at Visby Airport. They have discovered that on-site solar panels and battery storage could significantly reduce grid stress, and have proposed a novel approach to battery operation.

Italian researchers studied sodium-seawater batteries (SWBs) for short- and long-term energy storage on Sardinia and found that SWBs with wave energy smoothed out power fluctuations, while enabling a fully decarbonized power generation system over the long run.

For those who combine solar, batteries, and electric vehicles (EVs) at home, driving on sunshine is a realistic goal. However, there are many factors to consider when analyzing the economic payoffs, as well as the technical possibilities and limitations of such systems.

Gotion High-Tech has started making battery packs at its 20 GWh automated plant in Göttingen, Germany. It expects deliveries to clients in Europe to commence in October.

New research shows high potential for solar-powered vehicles across the world, providing between 11 km/day/kWp to 29 km/day/kWp of extended range in open areas, enabling significant levels of self-sufficiency.

US-based Sage Geosystems has presented field results showing that its Earthstore underground storage system can provide 18 hours or more of storage capacity, in addition to short-duration power. The solution is said to be cost-competitive with lithium-ion batteries and natural gas peaker plants.

Lithium-ion batteries are generally safe and unlikely to fail, but they can catch fire if damaged, stored, or operated incorrectly. With calls mounting for development of engineering good practice, US-based Firetrace International suggests three steps that battery manufacturers, developers and operators should take into account.

Australian researchers are proposing a novel, learning-based H∞ control method to enhance the performance of vanadium redox flow batteries in DC microgrids.

US researchers have developed a new high-voltage, membrane-free, nonaqueous lithium-based organic redox flow battery. They say that the elimination of the membrane decreases the upfront costs of the battery by as much as 30%.

University of New South Wales (UNSW) researchers have looked at energy losses in South Australia and have identified average curtailment of 1.5% for distributed PV sites and 0.2% for distributed PV coupled with batteries, but some locations experience generation losses of up to 25%.
