Smart grid operation while integrating photovoltaic through green hydrogen technology.

Abstract

Environmental pressures coupled with high fossil fuel prices have led to the rapid penetration of electricity generation from Renewable Energy Sources (RES). Because of the rapid RES penetration, the stability of grid energy infrastructures are now being heavily compromised and new solutions must be devised. A critical grid stability aspect when using RES is managing the mismatch of demand versus generation: 1) When there is low load demand for energy, RES could be at their peak generation 2) When there is high load demand, RES could be at their lowest generation. Any of the above scenarios can lead to a grid collapse, causing black outs. Increasing RES penetration, while maintaining stability, can be achieved by utilising Green hydrogen (H2) technologies within a 'smart grid' infrastructure. In a smart grid H2 set up, any excess in RES generation can be absorbed and stored as hydrogen gas through the use of electrolysis. This stored H2 can then be utilised in Fuel Cells (FC), gas turbines or internal combustion engines to generate power when RES generation is low or not available. Therefore, H2 can be considered as one of the most important enablers for RES in the world. The greatest challenges facing the uptake of H2 technology as a grid stabiliser solution are the cost reduction and the development of high value use for the hydrogen gas while improving its production efficiency.
