Energy Storage

The scramble for new battery solutions is accelerating as researchers from Singapore tout an electrolyte which which they say produces highly stable lithium-sulfur batteries that maintain performance metrics – a task which has proven tricky thus far.

The African Development Bank has agreed to invest $200 million to improve electricity access in Nigeria by building minigrids throughout the country.

Rebates are being offered to homeowners and businesses willing to couple small solar systems with energy storage.

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.

The move has been welcomed as a step in the right direction by lobby group SolarPower Europe nevertheless, particularly as it envisages bringing together EU low-carbon businesses. The outline ambition will now be considered by the European Parliament.

Dubai-based PV developer Enerwhere has come up with a new business model for solar projects at construction sites. Its approach, which is based on short-duration PPAs, involves moving mobile PV installations from one building site to another.

The UK Solar Trade Association has laid out its wish list ahead of new chancellor Rishi Sunak’s first budget speech tomorrow, with an exemption of solar from onerous tax valuations top of the agenda. COVID-19 measures, though, are likely to cast everything else into the shade.

Getting the most out of a bifacial module requires a rethink at almost every level of system design and the industry is hungry for field data generated by such systems to better inform energy yield modeling and define the best approaches to maximizing yield at minimal cost. In May, the U.S. National Renewable Energy Laboratory began a three-year study into bifacial performance which is beginning to yield results.

Although decried for lacking ambition and as an abdication of responsibility in some quarters, the climate law proposed by the European Commission may be more ambitious than it first appears, as Felicia Jackson, from the center for sustainable finance of the School of Oriental and African Studies at the University of London – considers here.

Toshiba has finalized construction of a 10 MW hydrogen plant in Fukushima prefecture which draws power from 20 MW of solar generation capacity as well as the grid.
