Compressor - demonstration of a new principle for efficient energy storage
A new effective principle for compressing air has been invented by Daniel Ehrnberg. The principle is published as a Swedish patent application No. SE1451403 A1. The principle uses water as pistons and creates an ideal environment to efficiently compress and expand air through many steps and at small temperature variations. This creates favorable conditions for a highly efficient energy storage. A prototype has been tested at Chalmers dept. physics with very good results. The technology could mean that we can provide Sweden's electricity system with 100% renewable energy and still maintain reliable deliveries. This in a carbon neutral, resource-efficient and cost-effective way.
