Storage

Swiss researchers conducted a survey among 1,582 single-family house owners located in Switzerland, Germany, and France to know more about their preference for leasing or buying a heat pump. They found that lease payments and lease contracts are crucial factors in decision-making, and that homeowners tend to prefer all-inclusive leasing products with lower monthly payments.

A tender for 600 MW/2.4 GWh of energy storage in Victoria and South Australia has been announced as part of Australia’s new national Capacity Investment Scheme, a project underwriting program coordinated by the federal government.

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.

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.

An international research group has applied for the first time integral backstepping control (IBC) as a control strategy for PV systems connected to microgrids. Through a series of simulations, the scientists found the new approach can provide better results than classic backstepping control (BC) and other techniques.

Lochinvar has developed a heat pump with a hot water supply of up to 70 C, with a coefficient of performance (COP) of 5.5. The system is entirely cascadable, offering outputs ranging from 88 kW to 880 kW. It also includes 455 liters of hot water storage capacity and uses propane (R290) as a refrigerant.

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.

Developed by scientists in Malaysia, the new PVT system is based on a nanoparticle-enhanced phase change material (Nano-PCM) and twisted absorber tubes. The system consists of a 30 W photovoltaic module, absorber tubes attached to the back of the panel via enhanced silicone glue bond, and a PCM container surrounding the tubes.

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.

Australian’s Incat Tasmania is building the world’s largest all-electric ship at its shipyards in Hobart. The 130-metre-long vessel is to be fitted with a 40 MWh battery energy storage system that will power a series of electric propulsion system and waterjets.
