Subsea pumped storage tech secures funding from US, German governments
A cross-Atlantic subsea pumped storage collaboration will seek to overcome the land-based challenges plaguing traditional pumped hydro storage technology.
Battery storage drives revenue for solar arrays in high-demand areas
One to four hours of battery storage for a solar power facility can significantly increase site revenue in areas with high population density or abundant solar energy. However, the added value diminishes with storage capacities exceeding four hours.
Solid-state batteries enter pilot production, costs expected to drastically drop
The latest findings from Taipei-based intelligence provider TrendForce show that all-solid-state battery production volumes could have GWh levels by 2027. The rapid expansion will lead to cell price declines, reaching CNY 0.6-0.7/Wh ($0,084-$0,098) level by 2035.
Test bench for aboveground compressed air energy storage systems
Researchers in Canada have created an experimental workbench for aboveground compressed air energy storage. Experimental data calibration reportedly ensured model accuracy with a mean absolute percentage error below 4.0%.
Australia has 7.8 GW of utility-scale batteries under construction
The volume of large-scale battery energy storage projects under construction in Australia passed that of solar and wind projects combined in 2023 and the trend has intensified this year, with batteries attracting federal support. As coal-fired power plants are shuttered, developers and suppliers are enjoying a battery bonanza.
Niger seeking consultants for 60 MW solar-plus-storage project
Niger Electricity Co. has asked consultants to submit expressions of interest for feasibility, environmental, and social impact studies for a 60 MW solar-plus-storage project in western Niger. The deadline is Dec. 2.
China’s GNE develops lithium-sulfur battery with energy density of 700Wh/kg
The energy density of the newly developed lithium-sulfur prototype far exceeds the one of common lithium -ion batteries.
Climate data-based methodology for residential air-source heat pump sizing
A European research team proposed a new air-source heat pump sizing approach that utilizes long-term climate data and adjusts system operation based on actual local climate conditions. The sizing algorithm incorporates peak heat demand, unitary final energy demand, and seasonal heat demand across different house sizes.
Hithium plans manufacturing capacity in Saudi Arabia, unveils desert-tailored battery storage solution
China’s Hithium has joined hands with a local partner to establish a 5 GWh production facility in Saudi Arabia. It has also unveiled its specialized energy storage solutions tailored for desert applications.
Powering restaurants with rooftop PV, reversible fuel cells
Researchers have simulated the operation of bifacial PV and proton exchange membrane reversible fuel cells across restaurants in five different US states. Taking into account varying rates of bifacial PV’s rearside gains, they found that LCOE was as low as $0.029 per kWh.
