Researchers at the University of Cambridge have examined one of the fastest-charging anode materials by using a low-cost, lab-based optical microscopy technique. Their findings showed that particle fracture, which can reduce the storage capacity of a battery, is more common with higher rates of delithiation and in longer particles.

UK researchers have revealed that gaseous hydrogen could cause problems in natural gas pipelines, while electrolyser manufacturer Nel has announced plans to build a second production line in Norway.

A team of researchers from the United Kingdom have found that crack percentages of up to 11% have a very limited impact on solar cell performance. They also ascertained that hotspots are likely to arise when the crack percentage is in the range of 11 to 34%.

An international research team has developed a new way to evaluate the economic value of energy storage technologies. They went beyond pure cost assumptions to consider the benefits that such technologies could bring to energy systems.

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 levelised cost of electricity of less than US$0.22/kWh (AU$0.32/kWh), while offering a self-sufficiency ratio of 0.95.

The UK Department for Business, Energy and Industrial Strategy has published new research showing that hydrogen leaks could have an indirect climate-warming impact, partly offsetting efforts to reduce carbon dioxide emissions.

UK-based analyst Exawatt and Germany’s Nexwafe published a white paper this week that takes a close look at the current state of PV manufacturing worldwide, and how Nexwafe’s innovative wafer production tech might fit into it. They said that if the potential of its Epiwafer can be realised, the PV industry may yet see “another revolution in wafer manufacturing.”

Australian-based mining giant Fortescue has commenced the development of an electric train that recharges itself using gravity after the resources company this week settled its $310 million purchase of UK-based technology and engineering services business Williams Advanced Engineering.

British start-up Gravitricity secured funds from the UK Department of Business Energy & Industrial Strategy (BEIS) to build its second gravity-based storage project. The feasibility study is expected to be finalised by the end of this year.

Australian technology company Lavo’s innovative energy storage system – based on storing green hydrogen in a patented metal hydride – has attracted the attention of the UK government which has provided financial backing to allow for a demonstration facility to be installed in England’s northwest.
