New study identifies 1,800 sites for pumped hydro storage in Alaska
Researchers at Argonne National Laboratory and the US National Renewable Energy Lab (NREL) have found that renewable energy can reduce the cost and emissions of electricity in remote parts of Alaska.
Australian manufacturer unveils 5.12 kWh battery for residential applications
Vaulta, an Australian battery tech company, has developed its first dedicated residential battery. The small-scale energy storage system can purportedly operate for 4,000 cycles, with an 80% depth of discharge.
The Hydrogen Stream: Gasunie reports strong interest in salt cavern H2 storage
Dutch gas supplier Gasunie says several market participants have reserved capacity in the first salt cavern for large-scale hydrogen storage near the Dutch city of Groningen. According to current planning, the first cavern will be operational by 2028.
Building to last in the Global South
PV initiatives should be designed to last, as several well-meaning off-grid solar projects for the developing world have floundered over the years.
Phase-change thermoacoustic heat pump for residential, industrial applications
The novel heat pump, developed by a research group in Israel, consists of a loudspeaker, a resonator, and a thermoacoustic core placed inside the resonator. The core includes a cold heat exchanger, a stack, and an ambient heat exchanger.
PV-driven controlled farming tech for non-electrified areas
Scientists from India conceived a new system for crop growth in remote areas with no connection to the power grid. It consists of a PV panel, add-on module hardware (AOMH), a battery, step-down DC-DC converters, system power devices, automation, and sensor elements. For climate control, it also comprises a water pump, a ventilation fan for CO2 assimilation, sprinkler foggers, and drop irrigation solenoids.
Austrian utility starts building 300 MWh organic flow battery project
Burgerland Energie has deployed a redox flow storage battery from German battery manufacturer CMBlu in the immediate vicinity of a PV-wind power hybrid power plant.
Australian grid operator testing community battery tech
A grid-connected community battery has gone live in Sydney, Australia, with New South Wales electricity distributor Endeavour Energy testing the tech to maximize the benefits of rooftop solar.
Japanese real estate firm starts residential solar hydrogen project
Sekisui House-W is testing a pilot project consisting of a residential PV system, a small-sized electrolyzer, hydrogen-absorbing alloy tanks, and a fuel cell. The company said the hydrogen storage alloys used in the project have higher energy density than battery storage.
UK coal-fired power plant site to host 1,040 MW/ 2,080 MWh battery
Independent energy infrastructure developer Carlton Power has secured planning consent for a 1,040 MW/ 2,080 MWh battery energy storage system (BESS). The project is expected to strengthen the resilience of the energy system in northwestern England.
