A Swedish-Iranian research team modeled 14 photovoltaic blind configurations in checkerboard arrays 1m above a greenhouse roof emulated with EnergyPlus building energy simulation software. The group found a PV installation would reduce natural gas consumption, electricity demand and carbon emissions.

A novel anion exchange membrane has been developed by German chemical company Evonik. Its creators claim it can make hydrogen generation cheaper, as the cells used for electrolysis featuring the device would not require precious metals.

Analyst IHS Markit has predicted storage will rebound this year following its first year-on-year decline in 2019. The technology is being rolled out at pace despite Covid-19 with state-level policies set to keep the US the global capital for the next five years.

Swedish start-up Azelio says it will have a pilot project up and running in Masdar City by the end of next month. The technology sees electricity used to super heat aluminum with energy released on demand via a heat transfer fluid to drive a Stirling engine.

The call is part of a government action plan for achieving net zero emissions by 2050.

The Japanese electronics giant has deployed a 3.5 kW hydrogen fuel cell system for at its Michinoeki-Namie site in the Fukushima prefecture. The fuel will be provided by the company’s 10 MW Fukushima Hydrogen Energy Research Field nearby.

The government has finally issued guidelines on how solar-powered irrigation system owners can be paid for exporting power back to the grid. However, for those who expect to have to use grid power to augment solar from time to time, there could be a sting in the tail.

German utility RWE will sell solar electricity to the German conglomerate under a 16-year power purchase agreement. The electricity will be generated by a 50 MW solar plant in southern Germany. Bosch has also sealed power supply deals with Statkraft and Vattenfall.

The British energy company has pledged to raise investment in low-carbon energy – including biomass and natural gas-fired hydrogen – tenfold by 2030 and said it would reduce its upstream oil and gas activity 40% over the same period.

Federal network agency the Bundesnetzagentur has announced it will retire 4 GW of coal-fired generation capacity through the exercise, which will see plant operators compete to secure one-off payments in return for shuttering, or converting operations.
