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.

Fortescue Future Industries has acquired Williams Advanced Engineering for $310 million as it looks to capitalise on its critical battery technology to cut emissions from its mining vehicles. An offshoot of the Williams Formula 1 Team, Williams Advanced Engineering has already helped to develop an electric mining haul truck for Fortescue in 2021.

Reliance Industries said its solar unit will buy UK-based sodium-ion battery technology provider Faradion for GBP100 million (AUD$187 million) including debt, as the Indian conglomerate pushes forward with its ambitious plan to move into the renewable energy industry.

With Scottish company Smarter Grid Solutions having already seen its software deployed in the U.K., a pilot project in New York State has been a resounding success for a grid solution the NREL has predicted could unlock swathes of network capacity without the need for new power lines.

Scientists have developed a new model based on fault tree analysis to evaluate the frequency of fires caused by rooftop PV systems and assess system safety and reliability. They claim that the new tool has the potential to identify fault linkages in systems, highlight failure patterns before they arise, and compare multiple designs for safety.
