Energy Storage

The new batteries reportedly provide steady operation for up to 16,000 charge cycles. It has a storage capacity of 5.4 kWh and a depth of discharge of 90%.

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 research group in China has proposed to solve the typical high working pressure issues of solar-powered sprinklers by using compressed air energy storage (CAES). According to their findings, combined PV-CAES sprinklers can easily achieve high pressure and low intensity high-quality water spraying.

Solegreen plans to deploy 210 MW/470 MWh of solar-plus-storage in Israel, through a project selected by the Israeli authorities in a 2020 tender. The facilities will sell power at ILS 0.1715 ($0.0459)/kWh.

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.

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.

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.

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.
