RE:Storage systemYou are right I thought those didn't have graphite their loading cycle are too slow for electric propulsion but perfect to store energy from solar panels or wind farm. Can you imagine at a end life of a dam now they might have a way to store all the energy when they will empty the reservoir! Put those on ships and could can sell electricity everywhere! Tons of graphite will be needed to empty one Dam alone ...
Hydro-Qubec’s move towards energy storage using LFP batteries
On December 9, 2020, it was reported that Hydro-Qubec announced the launching of a new subsidiary that specializes in energy storage systems in a bid to help speed up development of renewable power and commercialize technology it has developed over four decades.
A Reuters report quotes: “Hydro-Qubec, Canada’s largest electricity producer, on Wednesday entered the fast-growing market for storing renewable energy, where it could face competition from the likes of Tesla……Hydro-Qubec aims to capture 10% of a niche market expected to reach $3 billion in the next 10 years.”
Hydro-Quebec’s new EVLO subsidiary will design, sell and operate storage systems aimed at other utilities, commercial and industrial markets for medium-and-large-scale storage. They intend to initially focus on North America and Europe.
Hydro-Qubec is using lithium iron phosphate batteries (LFP). LFP battery is a type of lithium-ion battery using LiFePO as the cathode material, and a graphite based anode. It means there is no use of nickel or cobalt, but still uses lithium and graphite.
