Thermoelectric subcooling may improve coefficient of performance of propane heat pumps by 12%
An international research team has investigated how thermoelectric subcooling may be integrated into propane heat pumps to reduce power consumption in the vapor compression system. Their work showed this combination can not only reduce electricity consumption but also significantly improve heat pump performance.
Brazil to launch large-scale energy storage auction in 2025
The Brazilian authorities say they plan to hold a large-scale energy storage auction in 2025, potentially creating a market for large-scale storage facilities in the country.
Demand for large capacity battery storage cells goes strong as prices continue to slide
The analysis from Taipei-based intelligence provider TrendForce finds that the average price for lithium iron phosphate (LFP) energy storage system cells continued to slide in August, reaching CNY 0.35/Wh ($0.049/Wh). Meanwhile, demand for large capacity cells continued to grow at a steady pace.
European researchers unveil solid-state battery with 1,070 Wh/L energy density
A European research consortium has produced a prototype solid-state battery using a new manufacturing process that reportedly achieves high energy densities and can be implemented on modern lithium-ion battery production lines.
Australia launches multimillion-dollar green hydrogen auction with Germany
Investment confidence in Australia’s green hydrogen industry has received a $660 million boost following a joint declaration with Germany to negotiate supply chains that guarantee European buyers for Australian products.
Amea Power to build 1 GW of solar, 900 MWh of storage in Egypt
Dubai-based developer Amea Power has agreed to build a 1 GW solar plant with a 600 MWh battery energy storage system (BESS) and an additional 300 MWh BESS. This follows the signing of two power purchase agreements (PPAs) with Egyptian Electricity Transmission Co.
India launches 2 GW/8 GWh renewables-plus-storage tender
Solar Energy Corp. of India (SECI) has started accepting bids to set up 2 GW of renewable energy projects backed with energy storage systems for assured peak supply of 8 GWh. Bidding closes on Oct. 14.
Using surplus PV power for seasonal underground thermal storage
Scientists have proposed a new system that uses surplus PV energy in the spring and the autumn to charge up underground thermal energy storage for later use in the summer and winter. They have simulated it on a school facility in Seoul, with a few optional configurations for thermal storage. Power savings were up to 39%.
Works begin on 1.4 GWh Inner Mongolia project combining lithium-ion, redox flow storage technologies
The Dengkou Renewable Energy Storage Project is billed as the largest single-capacity energy storage station under construction in China.
Egypt set for giant solar-plus-battery storage project
Norwegian developer Scatec ASA has signed a 25-year power purchase agreement (PPA) for a 1 GW solar array and 100 MW/200 MWh battery storage project in Egypt. CEO Terje Pilskog says it is Egypt’s first hybrid solar-plus-battery project.
