Every once and awhile the US Government surprises with outstanding output that is scientifically sound, interesting and necessary – meeting that age-old measure of ‘necessary AND sufficient’.
Here’s a snapshot from the site, which is dynamic for different scenarios or tests
Here is the site’s introduction, quote:
The U.S. Department of Energy’s (DOE) Energy Storage Grand Challenge is a comprehensive program that seeks to accelerate the development, commercialization, and utilization of next-generation energy storage technologies. In support of this challenge, PNNL is applying its rich history of battery research and development to provide DOE and industry with a guide to current energy storage costs and performance metrics for various technologies. Cost and performance metrics for individual technologies track the following to provide an overall cost of ownership for each technology:
- cost to procure, install, and connect an energy storage system;
- associated operational and maintenance costs; and
- end-of life costs.
These metrics are intended to support DOE and industry stakeholders in making sound decisions about future R&D directions and priorities that move the U.S. closer to its goal of energy independence. The technologies currently being evaluated are:
- lithium-ion (lithium iron phosphate and nickel manganese cobalt chemistries)
- vanadium redox flow
- lead acid
- pumped storage hydropower
- compressed air energy storage
