Air-source heat pump for harsh, cold climates
Carrier will soon begin field tests for a prototype air-source heat pump for cold climates. It is designed to provide high-efficiency heating performance in harsh climates with temperatures equal or below negative 29 degrees Celsius, while being grid-interactive. The US-based heating tech specialist expects to commercialize the solution by 2024.
Novel redox flow battery paves way for low-cost storage
US researchers have facilitated the decoupling of power from energy design by incorporating a conducting carbon slurry in the negative electrolyte of an all-iron flow battery. In a new study, they describe the design considerations for slurry iron redox flow battery scalability.
The mobility rEVolution: PG&E obtains first V2G export rate for commercial EVs in US
PG&E has secured approval to set up a vehicle-to-grid (V2G) export compensation mechanism for commercial EV charging customers in California. Sono Motors is debuting its Sion solar electric vehicles in the US market, while Toyota and Jera are installing innovative second-life battery systems in Japan.
Mango Power unveils home and portable battery system
US-based Mango Power has developed a 3.5 kWh battery system that can be expanded up to 14 kWh. The product features LFP battery cells from CATL and can be charged through AC wall outlets, with solar panels, or via electric-vehicle chargers.
It’s time to combat utility opposition to solar
As part of Aurora Solar’s Empower 2022 online solar summit, Bernadette Del Chiaro, from the California Solar & Storage Association, will moderate a talk about electric utilities and how they have abused their monopoly position to discriminate against solar in the US. Here, she gives pv magazine a taste of the presentation.
Semi-solid flow battery tech promises to lower production costs by up to 40%
While still using conventional lithium-ion raw materials, 24M’s technology is said to reduce the number of steps required to manufacture battery cells and thereby the cost by up to 40%. The US company’s SemiSolid design is also said to deliver improved energy density, safety and recyclability.
Indian startup launches solar-linkable UPS system for residential, commercial applications
Su-vastika introduced a three-phase uninterruptible power supply (UPS) system with power ratings of 10 kVA to 500 kVA. The backup time provided by the system can be extended by using solar power in conjunction with the battery bank.
Polypropylene absorber to simplify brine heat pumps’ adoption
German company Mefa Befestigungs- und Montagetechnik has developed absorbers made of polypropylene that are intended to simplify the use of brine heat pumps. The novel technology should make it possible to combine multiple heat sources, including water, earth, air and also ice storage all within a single system.
Non-flammable, graphene-based lithium-ion batteries approaching stationary storage market
US-based Nanotech Energy’s graphene battery uses proprietary electrodes with a thermally stable separator, and non-flammable electrolyte that is said to be inexpensive to manufacture. The technology is said to be superior in terms of safety and competitive in terms of cell performance.
