Tectonic Metals gets funding for gold exploration in Alaska
The company's Flat gold project is located 40 km north of the giant Donlin gold project.
Solar use is growing at exponential rates, and countries like the U.K., France, and India are planning to ban gas-powered vehicles in the coming years. Even the world’s largest auto market in China is under duress from mounting pollution, and the country has ambitious plans to build up world-class renewable capacity while ditching gas-powered vehicles.
As the world shifts to renewables, one question remains up in the air: how will we store all this energy?
Today’s infographic comes to us from VanadiumCorp and it highlights vanadium redox flow batteries (VRFBs) – which are a breakthrough that some experts say may be the future of grid-scale energy storage.
As a result, VRFBs can be used in a variety of energy storage applications such as peak-shaving, load leveling, microgrids, wind and solar, off-grid power supplies, and uninterruptible power supplies.
VRFBs are getting more attention from utilities companies, and large battery projects have already been announced.
The most notable vanadium-flow battery is probably a 200 MW system being built on the Dalian peninsula in China, which will serve 7 million residents. Costing $500 million, it’ll be used to peak-shave approximately 8% of Dalian’s expected load by 2020. This battery system will be the world’s largest, and it will single-handedly triple China’s grid-connected battery storage capacity.
According to Chinese firm Azure International, the market projection for VRFB demand (by MW) in the top 10 countries is growing at an 80% CAGR from 2013 to 2020, ultimately culminating in more than 7,000 MW of vanadium-flow capacity needed in 2020.
This demand could be even more substantial than that if the price of vanadium electrolyte could be reduced – it makes up about 30-50% of the cost of each battery alone.
