Excess energy production can be stored in various ways technically. However, none of existing solutions are efficient enough to be broadly adapted. What Blockchain backed by proof-of-work allows is a new way to store energy - directly as various digital assets with Bitcoin as the most known representative. Huge Bitcoin mining farms require vast amounts of energy at competitive prices. Additionally they can be shut down or up and running in minutes. This gives unique property which allows it to be a part of DSR (Demand Side Response) system and help reduce risk of potential black-outs. InStar Energy Lab provides solutions for this kind of energy management.
