Distributed Storage

Industry body Recharge says it would be absurd if the makers of small batteries were required by law to collect and recycle products the size of shipping containers, and claim a requirement individual battery cells be replaceable will pose a safety risk.

A Swedish research group has developed a device combining CIGS thin-film solar modules and an alkaline electrolyzer based on a trimetallic cathodic catalyst made of nickel, molybdenum, and vanadium (NiMoV) and an anode made of nickel oxide (NiO). The electrolyzer achieved an average solar-to-hydrogen (STH) efficiency of 8.5% for stable operations during 100 hours.

Called GC PowerNest, the battery has a storage capacity of 5kWh and a voltage of 51.2V. It is scalable in an eight-stack configuration, thus reaching a capacity of up to 40kWh.

UL and the US National Renewable Energy Laboratory have released a report on cybersecurity certification recommendations and are actively developing new requirements to create cybersecurity certification standards.

The country’s cumulative PV capacity reached 22.56GW at the end of December.

The government of the state of Victoria will fund a floating PV array and an initiative to locally manufacture solar batteries and install a portable renewable energy system for community services during emergencies, as part of its Latrobe Valley program.

A Spanish consortium is equipping one of Madrid’s largest metro and bus stations with a hybrid system that combines PV, geothermal pumps, and vanadium redox flow batteries to provide cooling and heating.

Researchers from Australia’s Monash University have created a new generation of lithium-sulfur batteries to provide a cheaper, cleaner and faster-charging energy storage solution that outlasts lithium-ion alternatives and is rechargeable hundreds of times without failing.

Developed by Swedish manufacturer Polestar, the hard-top convertible incorporates a drone that can be launched from its dock behind the rear seats whilst driving to capture footage of the journey. In other news, Sony and Honda tie-up to make electric vehicles, Ford splits gas-powered and EV businesses, Stellantis unveils a strategic plan to reach net-zero by 2038, and Tesla offers free supercharging near Ukraine. Panasonic has also unveiled plans for two new production facilities for its large-format cylindrical battery cells.

A group of researchers in the United Kingdom is developing a modular, multi-vector energy system that can be installed into new homes and retrofitted into existing buildings to provide seasonal heat storage. In the proposed system configuration, a rooftop solar array would be used to power a heat pump or another electrical heating element, which in turn produces the heat to be stored by thermal devices.
