New research shows that the bottom of the sea porous rock can be used for energy storage

University of Edinburgh, according to a study released on 21 British north sea sea floor of porous rock is expected to be used for long-term storage of renewable energy power generation of electricity, so as to solve the storage problem such as offshore wind.

use of renewable energy sources such as wind power and solar energy power generation tend to rely on the weather conditions, so want to use it as a stable power supply mode, it is necessary to find a reliable and cheap energy storage technology. At the university of Edinburgh and the university of strathclyde researchers used mathematical model to evaluate a technique called & other; Compressed air energy storage & throughout; The potential of technology, and the technology is combined with British geological structure data of the north sea in the UK energy storage capacity.

, researchers say, is in the north sea in the porous rock drill in deep well, the use of renewable energy power generation of electricity to make the compressed air, and then the compressed air under the condition of high pressure storage in the hole of the rock seam; When the power shortage, the compressed air can be extracted, to drive a turbine to generate electricity.

the related research results published in the latest issue of British 'nature & middot; Energy journal. One of the authors of the report, the university of Edinburgh, Julian & middot; Jose - Castillo said the technology could store renewable energy power generation in the summer, for winter peak use. However, jose - Castillo admits, although this method has the feasibility, but the cost could be relatively high, & other; The future more research was needed to improve the technology, in order to cut down the cost & throughout; 。

the volatility of renewable energy generation to a certain extent, can be managed by grid, but in order to make renewable energy more competitive, and in the future to make the electricity grid to admit more renewable energy, you need to find a new intelligent energy storage solutions, to provide stable power. And through Batwind project, can know how to do this in the form of intelligence and create value.
