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.
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.
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.
New metallization tech for HJT solar cells minimizes silver use, increases efficiency
German research institute Fraunhofer ISE has unveiled a new metallization process for heterojunction solar cells that reportedly increases power conversion efficiencies by over 0.1% while reducing silver consumption. A device built with the new technique achieved an efficiency of 23.2%.
New model shows how to power homes exclusively with hydrogen, solar, batteries
Researchers in Spain has found that combining PV power generation with fuel cells and battery storage may help homes considerably reduce their levelized cost of energy. Their simulation reportedly demonstrated homes may also become completely self-sufficient.
Schneider Electric launches new storage systems for microgrids
The France-based group said its has released two new BESSs with enclosures of 7ft and 20ft. Their power ranges from 60 kW to 500 kW.
Photovoltaic water pumping based on open-ended winding induction
Indian scientists have designed a water-pump drive system that is powered exclusively by photovoltaics. The proposed system configuration reportedly ensures effective use of both the solar modules and the motor.
Solar module cooling tech based on waste neem oil
An international research team has placed a neem oil tank on the back of solar modules for cooling purposes. The proposed solution reportedly improves PV panel performance by up to 17.8%.
Growatt launches new balcony storage solution
The new product combines the NEO 800TL-X Microinverter and the NOAH 2000 Battery. Up to four batteries can be stacked, for up to 8,192 Wh of storage capacity.
Israel hits 51% renewable production for first time
The Israeli government said that earlier this month, for several minutes, renewable energy accounted for most of the nation’s energy production. In particular, solar covered 45% of total generation.
