Shenzhen LiTime Technology’s new lithium iron phosphate battery system has a nominal voltage of 12.8 V and a capacity of 100 Ah. It comes with a five-year warranty and can purportedly operate for more than 4,000 cycles.

New life-cycle assessment (LCA) data for PV systems confirms that greenhouse gas emissions from 1 kWh of solar electricity are far lower than emissions from fossil-fuel power plants. The difference has been fairly constant since 2018, but has improved substantially since when IEA PVPS started reporting on this measure in 1996.

South African researchers have developed a new cleaning system for solar panels that uses a color-sensing light-to-frequency converter to detect dirt. It can reportedly remove around 95% of the dust from a PV panel in less than a minute, at a lower cost than other systems.

Princeton University researchers have published a study on how the transition to hydrogen-based energy systems would affect the tropospheric burdens of methane and hydrogen, while Provaris Energy said it is moving forward with its compressed H2 carrier.

GoodWe has released a new solar-powered smart EV charger for residential use, Envision AESC has broken ground on a 12 GWh battery plant in the United Kingdom. and PG&E has invited customers to pre-enroll in its three upcoming vehicle-to-everything (V2X) pilot programs.

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.
