Abstract:
ETI modelling, using its Energy System Modelling Environment (ESME), shows that flexible power generation systems comprising hydrogen generation with CCS, intermediate hydrogen storage (particularly using salt caverns) and flexible turbines are attractive components in a future UK energy system. In such a system, hydrogen is supplied from coal and biomass fired gasifiers and steam methane reformers, with CO2 captured for storage - see Figure 1 below for hypothetical layouts. This permits the use at high load of capital intensive and relatively inflexible conversion and CCS equipment, filling hydrogen storage when power is not needed, and releasing hydrogen at short notice through turbines when power is at a premium. Superficially there are no barriers to using salt caverns as stores, as such stores are in use in the USA. However these are for high value added applications andnot for use in power where loss of efficiency is a more serious drawback. The ETI currently lacks sufficient data and knowledge to build a good representation of costs or efficiency (particularly relating to hydrogen storage) in ESME.
The purpose and focus of the proposed project is:
