On the Industrial Fire Protection blog, we write about battery storage often. You can find some of those blogs here:
While battery storage makes renewable energy more plausible by storing energy made during peak times for later use, the cost of those battery storage facilities is pricey. For example, 100 MW of renewable energy would cost about $65.6 million in massive batteries to store, according to Tech Crunch.
Tech Crunch spoke with Energy Vault to to talk alternative battery storage solutions.

Because solar and wind power are now cheaper to produce than energy from fossil fuels, the only obstacle that remains to the mass adoption of renewable power is the amount of money utilities need to spend to store the energy those systems produce.
Right now, storing 100 megawatts of renewable energy (enough to power roughly 600,000 homes) means spending roughly $65.6 million on massive batteries like the kind made by Tesla, or relying on huge pumped hydro-electric storage projects that essentially create man-made dams where the release of water spins turbines to generate energy (those projects are typically far larger than 100 megawatts).
A new company called Energy Vault, launched from Bill Gross’ Idealab incubator in Pasadena, Calif., has developed a technology, based on the principles of pumped hydro storage, that it claims can slash the cost of energy storage to a fraction of the current price and make renewable energy cost-effective all day, every day.
As climate change worries mount, finding a solution that can make renewables even more compelling and cost-effective isn’t just a good business — it’s a global priority.
