The International Energy Agency has acknowledged dramatic falls in energy investment caused by the Covid-19 crisis but said renewables, including PV, offered an attractive proposition to investors as the dust settled, given their enticing economics and short turnaround times.
German electric boating company Torqueedo’s 100,000th sale highlights a shift in leisure and small commuter boating towards the electric.
The British university will use Redflow zinc-bromine flow batteries at its Active Building demonstrator – an award-winning classroom that generates, stores and releases solar energy at the point of use.
An international group of scientists has developed a comprehensive method to track the microscopic processes at work in lithium batteries. Employing a ‘virtual unrolling’ model developed for ancient manuscripts too sensitive to be opened, the group peeked inside the layers of a commercial battery to gain a better understanding of the processes at work and the degradation mechanisms affecting them. Their findings, the group says, could provide a benchmark for battery characterization.
UK researchers claim to have proved the viability wearable photovoltaic devices as an integral part of regular clothing. A solar-powered fabric textile was created by embedding micro crystalline silicon solar cells within the fibers of a textile through very thin copper wires. The scientists claim that the novel device can maintain its performance even after 15 domestic machine wash cycles, 25 hand wash cycles, and 6000 abrasion cycles.
The global transition to a low-carbon energy future hinges upon the sustainable supply of green-tech minerals and metals, says researchers. Australia’s reserves and export capabilities in nickel, cobalt, lithium and other rare earths mean our next mining boom could be of global existential importance.
Researchers have made a finding they say could vastly simplify and reduce the production cost of perovskite solar cells. Working with mixed halide perovskites, the group found a disordered chemical composition can improve device efficiency.
