This week’s “Top 5” includes two storage projects in the Arctic and in Germany, an acquisition by Lockheed Martin, an update on Ambri and a new HVDC cable that could facilitate renewable energy transport.
1. Glencore is installing a 3 MW Enercone wind turbine on a nickel/copper Raglan mine in Arctic. The wind turbine could cut down the diesel consumption of the mine, the only current energy source, by 5%. Three storage technologies will be tested: batteries, a flywheel and an electrolyzer/fuel cells hydrogen storage. The hydrogen might also power vehicles.
This is a pilot project, which if successful, will spread into 9 to 12 MW wind plant with more of the most successful storage technology.
2. Flow battery developer Sun Catalytix was acquired by Lockheed Marteen for an undisclosed amount and will become Lockheed Martin Advanced Energy Storage.
3. German Article – Siemens AG is carrying on the final testing before starting the operation of a 1,2MW / 720kWh lithium-ion battery energy storage system that was installed last year at the steel industry of ArcelorMittal in Eisenhüttenstadt, Germany. Vulkan Energiewirtschaft Oderbrücke GmbH, a local utility, installed the system to procure a black-start capacity to start a 40MW gas turbine in case of blackouts.
4. An update on Ambri. The company has a working laboratory prototype and will send four prototypes to be tested on the field in the USA this year.
5. French article – ABB has developed a new 525 kV HVDC cable that will allow to transmit a power of 2.6 GW over 1500 km compared to 1 GW over 1000 km today. The cable is based on Cross-linked polyethylene. According to ABB, this new type of cable will be a great help to the transport of underwater and underground power coming from renewables.
