Storage

Alsym will produce its new batteries – made of readily available materials, without lithium or cobalt – for electric vehicles, stationary storage, and marine applications.

A Chinese-US research group has designed a proton exchange membrane fuel cell with a hybrid electrocatalyst. The scientists said the device shows remarkable stability and low performance losses.

Grid-scale and residential storage installations have set new records in the United States, despite supply chain concerns and pricing issues.

The government of the Australian state of Queensland has committed AUD 48 million ($33 million) to develop two pumped hydro projects.

Lake Onslow, New Zealand, could become home to one of the world’s largest pumped-hydro storage facilities. A local consortium is now conducting a feasibility study and is investigating possible system designs and precise locations.

US-based H2 Industries plans to produce hydrogen from organic waste and non-recyclable plastic. pv magazine recently spoke with its executive president, Michael Stusch, about the main technologies behind the project.

UK scientists have compared the performance of lithium-ion storage systems and vanadium redox flow batteries for a modeled 636 kW commercial PV system in southern California. They have found that both technologies, coupled with an oversized PV array, could achieve a levelized cost of electricity of less than $0.22/kWh, while offering a self-sufficiency ratio of 0.95.

Japan’s Arth has designed an autonomous habitation module that produces water in places without energy and water infrastructure. The company said the residential unit could also be used as an emergency evacuation site.

Scientists in Norway have managed to run a micro gas turbine plant on pure hydrogen. They claim their experiment paves the way for the use of existing infrastructure to generate heat and power with the green fuel.

Mitsubishi and Japanese utility Kyushu Electric Power are teaming up to use more grid-scale storage, in order to reduce financial losses caused by curtailment.
