Storage

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.

Australia-based mining giant Fortescue has started the development of an electric train that recharges itself using gravity, after settling its recent purchase of UK-based Williams Advanced Engineering.

A UK consortium is developing an organic flow battery technology that could be used in ports to supply power to visiting vessels and in-port assets such as cranes and port vehicles. The electro-chemistry for the batteries is being supplied by German battery manufacturer CMBlu, which developed a flow battery relying on high-performance energy storage molecules that are entirely organic.

The US Department of Energy’s Pacific Northwest National Laboratory has made a third semi-exclusive commercial license for vanadium redox flow battery technologies, in order to help bring the technology to market.

Built by Korean oil provider SK Energy and the Seoul Metropolitan Government, the “Energy Super Station” is equipped with 20kW of solar panels and 300kW of fuel cell stacks. It can refuel conventional combustion vehicles as well as electric vehicles and fuel cell cars.

Swedish researchers have developed a novel way to manufacture micro supercapacitors, also known as system-on-a-chip, so they are compatible with other components in system circuits and can be easily tailored for different uses.

The realization of biodegradable batteries is a step closer thanks to research from South Australia’s Flinders University, which has developed a 2.8V organic polymer battery. While this battery was made from synthetic polymers, research lead Zhongfan Jia told pv magazine Australia the team’s future iterations will source “materials directly from nature” saying this promises to reduce waste and reliance on mined materials and could have novel applications in fields like biotech.

Michigan’s Our Next Energy (ONE) said it will use the funding led by BMW to accelerate R&D and build a US manufacturing facility.

Fortescue Future Industries says the first electrolyzers to be manufactured at the facility, early next year, are earmarked for use in Queensland at FFI’s planned green-hydrogen-to-ammonia project on Gibson Island.

Developed by Germany-based hydrogen specialist Enapter, the EL 4.0 electrolyzer is based on a patented anion exchange membrane (AEM) technology. Commercial production is currently being prepared at the company’s Italian plant and the first shipments should be made in the summer.
