Energy Storage

Scientists in Spain have proposed to combine anaerobic digestion plants with photovoltaic-thermal panels and have found that this combination may achieve an LCOE of $0.045/kWh across several locations in Europe and North America.

The South African Government’s Department of Mineral Resources and Energy announced French utility Électricité de France (EDF) will develop 257 MW of battery energy-storage systems across three projects, while South African renewable energy company Scatec Africa will develop one 103 MW project.

Toshiba has developed a 1.5 Ah lithium-ion battery prototype with a voltage of more than 3 V. The device retains its initial efficiency for over 6,000 charge/discharge cycles and enables rapid charging to 80% of capacity within just five minutes.

A research group in South Africa has developed a novel method for PV output forecasting in commercial buildings. The proposed approach is purportedly able to accurately forecast the output power of a PV plant using real-time weather data.

Daikin has released a line of residential air-to-air heat pumps, using difluoromethane (R32) as the refrigerant, with outdoor unit dimensions of 662 mm x 442 mm x 1022 mm. The output ranges from 2.5 kW to 3.5 kW, and the seasonal coefficient of performance (SCOP) is between 4.85 and 5.17.

Australian energy giant AGL will install a nickel-hydrogen battery at its Torrens Island power station site in South Australia as it explores the potential opportunities that the technology could provide for stationary energy storage applications

Developed by researchers in China, the novel calculator uses current and voltage sensors, a Raspberry Pi, and an algorithm for fuzzy logic to determine variations in frequency and demand. The tool sends Email notifications with the tariff values to the PV system owners.

For the seventh year in the row, China-based Contemporary Amperex Technology Co. (CATL) looks set to claim the title of the world’s biggest battery maker. There are a number of reasons why it continues to maintain its lead in the electric vehicle (EV) and battery energy storage system (BESS) markets..

Madrileña Red de Gas is testing a heating system prototype developed by Germany company Vaillant that uses exclusively green hydrogen. The 25 kW system is equivalent in shape and size to a current natural gas heating system.

Danish investment group Copenhagen Infrastructure Partners has tapped Canadian PV and battery manufacturing heavyweight Canadian Solar to provide energy storage solutions for the first of several large-scale battery projects it has planned for Australia.
