Their California-based startup Terrajoule is applying an older technology, namely steam engines, to build a storage system that could lower the cost to under $100 per kWh, which is less than 20 percent of what it costs for current battery storage systems. This new system will also last longer (it has a 25 year lifecycle), thereby eliminating use of the toxic and rare materials contained in batteries.
