Gas Distribution Networks
The study will consider three scenarios which will be used for design purposes for an alternative low carbon hydrogen production system utilising ATR/Ammonia and CCS and the associated impacts on the UK gas networks system for large scale roll out.
Scenario 1: 1 x Leeds approximately 1 GW hydrogen (average annual production 678MW) and 1.5 million tonnes of CO2 per year developed in 2025.
Scenario 2: 10 x Leeds approximately 10 GW hydrogen and 15 million tonnes of CO2 per year developed between 2025-2035 @ 1 GW additional hydrogen production generation per annum and 1.5 million tonnes additional CO2 sequestration requirements per year.
Scenario 3: 50 x Leeds approximately 50 GW hydrogen and 75 million tonnes CO2 per year developed between 2025-2045 @ 2.5 GW additional hydrogen production generation per annum and 3.75 million tonnes of additional CO2 sequestration per year.
The study will also be used to support the H21 – Strategic modelling – Major Urban Areas NIA which is due to be registered in April 2017.
In considering the success of the project we would consider the following success criteria as a minimum output from the project;
- Provide an assessment of the technical and economic opportunities for hydrogen production utilising Auto Thermal Reformation, ammonia storage and CCS deployment rates to allow an assessment of the relative merits of ATR vs. SMR hydrogen production in the context of the three identified scenarios
- Provide an assessment of the technical and economic opportunities for hydrogen in ammonia transport and storage, to allow an assessment of the relative merits of hydrogen in ammonia vs. salt cavity storage in the context of the three identified scenarios
- Provide a technical assessment of the feasibility and costs of converting existing CCGT power generation to hydrogen.
- Provide a feasibility report, including a high level economic assessment for CO2 storage options against the three identified scenarios utilising existing Statoil pipelines and storage infrastructure.
- Understand the technical impact of this system on the UK gas network including transmission and distribution networks
- Provide critical rates of conversion data for 1, 10 and 50 ‘Leeds equivalents’ to inform the H21 – Strategic modelling – Major Urban Areas NIA which is due to be registered in April 2017.
