High-voltage sodium-ion batteries with up to 15% higher energy density
Researchers in Russia have developed a new sodium-vanadium phosphate fluoride powder. It has a particular crystal structure that provides superior energy storage capacity in the battery cathode.
Straight to storage via solar integrated batteries
Scientists in China evaluated the prospects for various approaches to integrating both solar generation and energy storage in a single device. Their work outlines several ways this could increase the efficiency of solar energy storage, and recommends that future research on this area should focus on integration of materials with the highest specific capacity for energy storage, alongside the dual function of solar energy harvesting.
Hysata brings capillary-fed eletrolyzer tech closer to commercial production
Australian startup Hysata is seeking to commercialize a breakthrough made at the University of Wollongong which CEO Paul Barrett describes as a “brand new category of electrolyzer” with 95% system efficiency.
The role of seasonal demand in an all-electric scenario
Peak solar production does not coincide with peak heating demand, and a team of researchers determined that meeting this demand with renewables alone will require massive deployment of renewables on top of existing fossil generation.
Toshiba energizes PV-powered hydrogen refueling station in Japan
The system is reportedly able to refill about eight hydrogen fuel cell vehicles, each in three minutes. It is also able to supply electric power by using hydrogen produced with renewable energy within the station.
New residential lithium-ion battery from China
Chinese manufacturer Bslbatt has unveiled an upgraded version of its residential battery. The device has a storage capacity ranging from 5.12 to 12.8 kWh and is reportedly able to provide steady operation for up to 6,000 charge cycles.
JinkoSolar unveils battery system for Australian residential market
Having established a strong foothold in the Australian market with its solar PV panels, Chinese manufacturer JinkoSolar is now seeking to expand its influence in the energy storage space with the launch of its modular Suntank home battery storage system.
NGK Insulators links 200 kW/1,200 kWh NAS battery to 2.6 MW rooftop solar array at Japanese factory
Both the battery and the PV system are due to begin commercial operations in 2024.
UPDATED – New tech to produce hydrogen from tap water
A Spanish scientist has developed a system that reportedly produces hydrogen on-site without expensive electrolysis. The prototype utilizes a water tank that is initially filled with water, ferrosilicon, and sodium hydroxide.
Electriq Power residential batteries beat the heat with backup power, smart time of use
A home battery paired with rooftop solar can provide backup power during rolling blackouts, shift power usage schedules to avoid peak demand charges, among other benefits.
