A New High Energy Storage Concept for Solar PV

If you cannot beat them, then join them

 Hydrogenics Corp. announced that it has entered into an agreement with Enbridge Inc. to jointly develop utility scale energy storage in North America. The collaboration will bring together Hydrogenics’ expertise in water electrolysis with Enbridge’s expertise in the ownership and operation of natural gas pipeline networks and renewable energy generation. . With ’Power-to-Gas’, the hydrogen produced during periods of excess renewable generation will be injected into the existing natural gas pipeline network, proportionally increasing the renewable energy content in natural gas pipelines for essentially the operating cost of the electrolyzer. Small quantities of hydrogen can be manageable in existing natural gas pipeline networks. With the significant scale of the natural gas pipeline network, these same quantities of hydrogen have a very meaningful impact on electricity energy storage potential. The natural gas pipeline network represents a vast energy storage system which already exists. The utility scale energy storage leverages existing natural gas pipeline and storage assets to enable improved operability for the electrical system. Furthermore, the economics are further improved by leveraging existing gas generators to bring this renewable energy back to the electrical grid where, and when, it is needed most.
