Energy Storage

Two projects have been deployed by Canopy Power on private islands in Indonesia. The two 52.5 kW/77 kWh mini-grids were the only alternative to diesel generators due to the lack of a connection with the grid on the island of Batam. The projects – which rely on REC Solar modules, SMA inverters and a storage system from Tesvolt – provide around half of the energy required on their respective islands.

The German storage system provider intends to use its ‘Sonnen-Flat’ payment package to help customers benefit from the proceeds of its virtual power plant.

Austrian researchers have proposed gravitational energy storage for locations with low demand. The scientists claim the system they are suggesting can be combined with other forms of storage as well as renewables, costs $50-100 per megawatt-hour of stored energy and $1-2 million per megawatt of installed capacity to develop.

PV industry veteran Karl-Heinz Remmers recalls the trajectory of solar power this decade and predicts stronger than expected development for the ten years ahead.

The energy transition is becoming ever more apparent among power companies, as was evident at the European Utility Week event last week in Paris, which showcased the hopes and fears of energy companies. Rebranding next year to ‘Enlit’, the organizers aim to reach the whole energy industry.

A cooperation agreement was signed by the French corporations to launch the HyGreen Provence project, which is expected to produce annually 1300 GWh of solar electricity and 10,440 tons of green hydrogen by 2027.

Australian startup Power Ledger wants to scale up its offerings for much larger communities, as it has already verified its technologies in projects around the world. The Australian Energy Market Commission last week proposed a similar agenda.

The Salt River Project has announced a 250 MW, 1,000 MWh battery project in Little Rainbow Valley, Arizona. The installation will be the largest in the state and among the largest in the United States.

Scientists led by Moscow’s Skolkovo Institute of Technology have drawn upon several of their recent battery material innovations to create a potassium-ion device. The institute says its development will pave the way for ultrafast and durable, high capacity metal-ion batteries, to supply rising demand for energy storage innovations.

Britain’s renewable energy trade body has published a report examining the state of flexibility market readiness in nine European markets. The result makes for sobering reading for Germany, France and the U.K.
