The basic idea is that specially designed hydraulic wind turbines are used to compress nitrogen into existing gas or oil pipeline infrastructure, some of it unused throughout North America. Several hundred, even thousand, kilometres of pipeline could be filled with nitrogen and kept under pressure, in effect becoming a kind of massive nitrogen battery for wind. When electricity needs to be generated anywhere along the pipeline, the nitrogen gas is released and expands to turn a turbine that generates electricity. Wind, under this setup, suddenly becomes dispatchable and has baseload characteristics. Also, the pipeline eliminates the need for transmission lines.
