f HyNTS Compression, Alpha Technical Report

The HyNTS Compression project investigates the key challenges associated with compression of hydrogen, and hydrogen blends, through NTS assets. The project will determine the most cost-effective, technically feasible solution for hydrogen compression on the NTS and develop the strategy for hydrogen compression. The alpha phase of the project has focussed on the following, before progression to the beta phase of the project:
• Business case and Requirements for hydrogen compression
• Gas Turbine System
• Compression System
• Ancillary Equipment
• Demonstration Facility Development
The conceptual design development has concluded that it is possible to repurpose existing compression assets to demonstrate their capability of operating with 100% hydrogen. This will obtain the evidence necessary to update the Safety Case to enable deployment across the NTS. This phase of work further reinforces the importance of carrying out a demonstration to gather evidence of how repurposed compression assets would operate and the impact this would have on their performance. If repurposing NTS compression assets for hydrogen service can be proven, there is potential for huge savings when realised across the entire NTS compression fleet.
This report was submitted to HSE for their assessment of the safety evidence for 100% hydrogen heating, which can be found at Hydrogen heating: HSE assessment of the safety evidence - GOV.UK.
