Rheem presents residential heat pump
The heat pump uses R-410a as a refrigerant and has a size ranging from 2 tons to 5 tons or 7.0 kW to 17.6 kW. It also has a cooling capacity spanning from 6.7 kW to 15.5 kW.
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.
Panasonic presents air-to-water reversible heat pumps
The Japanese electronics manufacturer said its new heat pumps are suitable for commercial, industrial, and multi-dwelling residential applications. The new products feature a rated power ranging from 50 kW to 80 kW and a coefficient of performance spanning from 3.2 to 3.4.
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.
US utility-scale solar capacity additions hit 36.4 GW in 2023
The US Energy Information Administration (EIA) says it expects developers to install nearly 63 GW of utility-scale electricity capacity in the United States in 2024 – mostly a mix of solar and batteries. It notes that the nation added roughly 36.4 GW of solar in 2023.
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%.
MW Storage, Fluence partner on Germany’s largest storage project
Storage specialist Fluence says its new battery-based energy storage project in Germany will be one of the largest in continental Europe, with a capacity of 100 MW/200 MWh.
Puerto Rico distributed solar rises to 680 MW, residential storage to 1.6 GWh
While distributed solar and storage are advancing quickly in Puerto Rico, utility-scale solar and storage procurements ordered by regulators in 2020 have made little progress.
