Leapton Energy launches 20.48 kWh residential battery

Japan’s Leapton Energy has developed EH-A05, a 20.48 kWh residential battery featuring storage capacities starting at 5.12 kWh, with lithium iron phosphate (LFP) batteries.

Atess Power releases new series of BESS containers

Atess Power has developed a new series of battery energy storage system (BESS) containers. The Chinese manufacturer is offering 20 HC and 40 HC containers, as well as battery-only containers with storage capacities up to 3,440 kWh.

Cadmium-doped perovskite solar cell achieves 22.7% efficiency

A Chinese-Canadian research group has utilized for the first time a cadmium iodide doping technique to stabilize the blade coating process in the manufacturing of solar cells based on formamidinium lead iodide (FAPbI3) perovskite. The academics built a cell showing a considerable increase in efficiency compared to an identical device without cadmium doping.

3D printed clamps for front-surface PV mounting on wood racking

A Chinese-Canadian research team proposed a new PV mounting solution relying on two types of spacers and two types of clamps that can be printed with common printing materials. The cost of the different solutions presented varies from CAD1.50 ($1.10) to CAD3.83.

DAH Solar launches 380 W BIPV module

The Chinese manufacturer said the new product has an efficiency of up to 19.46% and a temperature coefficient of -0.30% per C. It is available in bright red, light gray, brown, green, blue-green, orange, and ocean blue.

Techno-economic feasibility of hydrogen storage in hydro-dominated countries

Scientists have investigated different techno-economic scenarios for using hydrogen storage in combination with hydropower and pumped hydro storage in Switzerland. They have found that hydrogen storage plays no major role under most conditions.

Off-grid solar-wind power plant design for green hydrogen generation

Scientists in Czechia have conducted a techno-economic analysis of a green hydrogen production system powered exclusively by photovoltaic and wind energy. The system uses surplus energy for water treatment and, according to its creator, can achieve a levelized cost of hydrogen of $3.12/kg.

The warming effect of PV on land surface temperature

Researchers in Japan have analyzed the warming effect of photovoltaic system on land surface temperature around the Kushida River Basin for ten years and have found this value increased by an average of 2.85 C.

The impact of seasonal, meteorological factors on PV plant performance

Scientists in Japan have investigated the impact of seasonal, metereological factors on solar plant performance and have found the average power generation inefficiency reached significant levels. The findings suggest that optimal site for power plants requires careful consideration of meteorological and geographical data.

Low platinum fuel cells for hydrogen vehicles

New research from Sweden suggests that low platinum fuel cells for hydrogen vehicles, when scaled up for the same number of cells, may achieve similar or higher efficiencies compared to commercial fuel cells. Their modeling is expected to act as a bridge between material science research and vehicle implementation.
