Giant transformers for grid debottlenecking

Dutch power company Liander has installed two large transformers at a distribution station in Ulft, in the province of Gelderland. The devices should provide more room for renewables on the network from next year.

Covid-19 daily bulletin

pv magazine rounds up the latest Covid-19-related stories likely to affect the world of solar and energy storage.

Jordan switches off unsubsidized solar projects

The Middle Eastern kingdom has ordered the shutdown of solar wheeling facilities which use the grid to connect to energy offtakers. The move has come in response to tumbling electricity demand after the nation halted all non-essential industries as it tries to limit the spread of Covid-19.

New fractal solar panels combine efficiency and aesthetics

Researchers from the United States have proposed a new electrode design for fractal solar panels that combines the typical aesthetic advantages of the technology with the efficiency of busbar design. The proposed pattern is based on the fractal tree structure known as H tree, or T-branching, which is a geometric shape consisting of a repeating pattern that resembles the letter H. The hybrid H-tree/busbar pattern showed power losses that are close to those of standard busbars.

Sector coupling in Europe could see solar and wind demand double

Market intelligence firm BloombergNEF has published a report with power company Statkraft and clean energy distributor Eaton highlighting the importance of sector coupling for Europe’s decarbonization plans. Analysts examined the power markets of Germany and the U.K. and concluded effective sector coupling including the use of green hydrogen could lead to greenhouse gas emission reductions of 83% by 2050.

Cheaper flow batteries with new membrane

US scientists claim to have discovered a membrane which could lead to cheaper large scale flow batteries. The material is an ion-selective, aqueous-compatible polymer with intrinsic microporosity known as AquaPIM and is said to have tunable thickness and high conductivity in aqueous electrolytes.
