Lithium-ion vs. vanadium redox flow storage

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.

UK government warns of global warming risks related to hydrogen leaks

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.

New technologies, new opportunities

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.”

Fortescue accelerates plans for gravity-charged electric powertrain

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.

Australian hydrogen battery technology to be tested in UK

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 acquires Williams Advanced Engineering in drive to win race to net zero

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.

Grid software solution could more than double network capacity for renewables with no new infrastructure

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.

New tool to understand component failure rate in PV-related fires

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.
