The purpose and focus of the Hydrogen Turbines project is to improve the ETI’s understanding of the economics of flexible power generation systems comprising hydrogen production (with CCS), intermediate hydrogen storage (e.g. in salt caverns) and flexible turbines, and to provide data on the potential economics and technical requirements of such technology to refine overall energy system modelling inputs. The final deliverable (D2) comprises eight separate components. This document is D2 WP1 Report – providing results of a techno-economic assessment of options for hydrogen power production from coal, coal/biomass and gas. It covers:
Options for hydrogen production
Techno-economic definition of the selected hydrogen production options
Characterisation of basic design requirements for a cost effective hydrogen store

The final deliverable (D2) comprises eight separate components. This document is D2 WP3 Report – providing a series of supporting studies:
Identification of potential salt cavern locationswithin UK and first 25 miles of UK Continental Shelf;
Salt cavern cost structure;
HSE challenges of cavern construction and operation;

The ETI’s energy system modelling shows that flexible power generation systems comprising hydrogen generation with CCS, intermediate storage (particularly using salt caverns) and flexible turbines are attractive options for the UK. In the model described here, hydrogen is supplied from coal and biomass fired gasifiers and steam methane reformers, with CO2 captured for storage. 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

This executive summary covers the objectives and main findings of the five work packages, and suggests the next steps.
