Challenges of integrating heat pumps into existing multifamily houses
New research from Germany shows that most of the heat pumps deployed in existing multifamily buildings may have to operate close to their water temperature operating limit (WTOL), thus being unable to provide elevated temperatures above 60 C. The researchers warned, however, that proper installation proceedings and new types of heat pumps may help solve this issue.
Australian coal plant tests iron flow batteries
Energy Storage Industries is delivering 1 MW/10 MWh of flow battery storage to the Stanwell Power Station in the Australian state of Queensland. The flow batteries are part of a new government-run clean energy testing “hub,” featuring hydrogen and additional workforce training programs.
Jaguar building large-scale storage system with second-life EV batteries
Jaguar Land Rover and Wykes Engineering are building a 2.5 MWh storage system with electric-vehicle batteries taken from Jaguar I-PACE cars. The large-scale system will store wind and solar at an undisclosed location in the United Kingdom.
Redesigned zinc-air batteries ‘better’ than lithium, say Australian researchers
Researchers at Edith Cowan University in Australia have redesigned zinc-air batteries and have found the technology to be preferable to lithium-ion batteries – even for electric vehicles.
Energy management system to combine residential PV with gravity storage
Researchers in Morocco have created a new energy management system that allows the combination of rooftop PV with gravity storage. The proposed system is reportedly able to perform smart energy distribution within a household while also lowering electricity costs.
