Western Australian peer-to-peer (P2P) energy trading pioneer Power Ledger has revealed the world’s biggest ‘choose your own energy source’ project in France.

France’s Sunbooster has developed a technology to cool down solar modules when their ambient temperature exceeds 25 C. The solution features a set of pipes that spread a thin film of water onto the glass surface of the panels in rooftop PV systems and ground-mounted plants. The cooling systems collect the water from rainwater tanks and then recycle, filter and store it again. The company claims the technology can facilitate an annual increase in power generation of between 8% and 12%.

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.

Volkswagen Commercial Vehicles has unveiled the e-Bulli, a concept blend of the classic 1966 Bulli Kombi with 2020 electric vehicle driving.

The ‘best conversion performance in the world in a dark room’ is how the developers of a new organic PV device have described it. Such cells could be used as a wireless source of energy for internet of things applications or in gadgets such as temperature-humidity and motion sensors.

A report by Norwegian energy consultant DNV GL has considered the opportunity for long-term energy storage to play a role in balancing annual supply and demand fluctuations in a renewables-led grid. Using 58 years of Dutch weather and energy consumption data, the study found long-term solutions such as green hydrogen could make a valuable contribution – but perhaps not as much as some analysts believe.

Researchers led by Belgian institute imec claim to have achieved the result with a 1cm² flexible thin-film cell intended for building-integrated PV application. The result tops the 24.6% efficiency the consortium announced in September 2018. The cell’s developers are now aiming for 30%.

Norwegian giant Equinor is the latest oil and gas company to abandon controversial plans to drill in the Great Australian Bight, following in the backtracks of BP, Chevron and Karoon Energy.

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.

West Australian peer-to-peer (P2P) energy trading pioneer Power Ledger has won a lucrative contract with Alperia SpA, one of Italy’s largest renewable electricity utilities.
