While the climate summit held at Sharm El Sheikh last month prompted pledges of raised funding for solar lanterns and single-panel systems, the money allocated to date is woefully short of what has been estimated would be required to provide universal access to electricity this decade. Drew Corbyn of Netherlands-based global off-grid solar body GOGLA, outlines three urgent courses of action to accelerate access to electricity.

Germany has announced plans to sign long-term green ammonia purchase agreements, in addition to strengthening its ties with Australia. Repsol and Fusion Fuel, meanwhile, are advancing their hydrogen projects on the Iberian Peninsula.

The International Energy Agency says that it expects the use of renewables to support global hydrogen production to surge over the next five years. The Netherlands and Denmark, meanwhile, have revealed plans to expand electrolysis capacity.

Acciona Energia is setting up its first V2G network in Spain, ADS-TEC has unveiled a battery-based, all-in-one system with up to 300 kW of charging power, and Volkswagen is looking for a location for its first battery cell factory in North America.

Japanese researchers claim that tin sulfide solar cells could achieve higher open-circuit voltages by preventing “Fermi level pinning” from occurring, due to the addition of a tin sulfide interface with large band bending.

While solar modules and inverters can greatly influence the output of a planned solar project, it is important not to overlook how to select and design cabling systems for your solar plant – for safety as well as generation considerations. Ye Qilin, a senior system engineer at Huawei’s FusionSolar smart PV and energy storage business, runs us through some dos and don’ts.

Th International Energy Agency (IEA) says unsubsidized heat pumps are already competitive with gas boilers in mature markets like the United States, Canada, Japan, Italy, and China. It says global sales will soar to record levels by 2030.

Japan’s Itochu has announced a new tie-up with France’s Rosi Solar, which develops tech to recover and recycle high-purity silver, copper and silicon from solar modules.

Ibis Power has developed a rooftop system that combines solar with wind turbines designed for medium-sized structures and high-rise buildings. It claims its PowerNEST system can produce six to 10 times more energy than standalone rooftop solar. The company has already installed five projects in the Netherlands.

Mitsubishi has released a cascaded air source heat pump that can produce between 7.8 kW and 640 kW of heat. It is reportedly able to generate hot water at a temperature of up to 70 C without boost heaters.
