UK researchers identify optimal heat pump design minimizing system transition costs
Researchers led by the Imperial College London have analyzed the effects different kinds of air-to-water heat pumps will have on the UK energy system, based on their coefficient of performance and price. They also identified a point of diminishing returns, after which it is more cost-effective to invest in centralized energy generation and storage.
Trina Storage releases 4.07 MWh energy storage system
Trina Storage has developed a 4.07 MWh energy storage system featuring its in-house 306 Ah lithium iron phosphate battery cells, configured with 10 racks of four battery packs.
Greece awards 300 MW in storage tender
The Greek authorities have awarded 300 MW of new battery storage capacity in the nation’s second energy storage tender, split among 11 projects. The tender is part of the country’s 1 GW energy storage auction program.
Simulation model to determine coefficient of performance of air-source heat pumps
A Dutch research team has outlined a new method to assess the coefficient of performance of air-to-water heat pumps by considering ambient temperature and relative humidity. The model is based on the equalization of the so-called logarithmic mean temperature difference (LMTD), which determines the temperature driving force for heat transfer in flow systems such as heat exchangers.
Survey highlights fire-detection, suppression issues in battery storage systems
A new Clean Energy Associates (CEA) survey shows that 26% of battery storage systems have fire-detection and fire-suppression issues, while about 18% face challenges with thermal management systems.
Green hydrogen, power generation tech based on compressed air storage, solid-oxide electrolysis cells
Scientists in Korea have developed a compressed air storage system that can be used as a combined cooling, heat, and power system and provide heat and power to solid-oxide electrolysis cells for hydrogen generation. It showed an overall roundtrip efficiency of 121.2% and over-unity efficiencies in the range of 100% to 120%.
Australian off-grid project upgrade shows power of modern PV
An off-grid residential system on a secluded island in Australia has received a new tech upgrade. The additional capacity highlights the new era of off-grid living available to remote households in the country.
