Abstract:

As the world turns towards a renewable energy dominated energy landscape, the storage of intermittent energy becomes ever more important. Balancing supply and demand is crucial with many intermittent sources not correlating with user requirements. Additionally the energy landscape is changing from a traditional, one to many approach where one power station delivers energy to a multitude of houses and businesses, to more distributive many to many approach where the network is highly complex with multiple sources big and small feeding into the system and many consumers all needing to be balanced. This talk will look at how hydrogen holds a potential solution to decoupling of supply and demand and the reconfiguration of the network. All renewable energy sources that are not immediately consumed can be converted into hydrogen which acts as a universal energy vector storing and distributing the energy where needed. We will show how new water splitting technology can achieve low cost, high efficiency energy transition and how a green hydrogen smart grid has been operated in Swansea. We will also look at potential projects around the world that could benefit from installations. Recent Publications 1.
