Carbon Emission Reduction Technologies and Environmental
The UK government has committed to reducing greenhouse gas emissions by 80% of 1990 levels by 2050. The government’s plans identify the need for low or no carbon heat as being essential for meet this target. 

SGN are involved in a variety of Environmental and low carbon projects. The findings from this project will provide beneficial information to ongoing SGN projects such as H100, as well as providing a greater understanding of the impact of hydrogen blending on the NTS and GDN’s.

The outcomes from this project will be a number of reports that can be used to demonstrate the feasibility of injecting hydrogen into the transmission system.
The objectives of this project are to:
  • Outline the possibility of using advanced SMR hydrogen production at St Fergus. And to discuss the technology and safety requirements for the transportation and storage of CO2 from SMR.
  • Identify the planning consents and environmental permits that would be required. This will also outline the health and safety related aspects of plant development as well as identification of relevant key HSE regulations.
  • Describe the introduction of hydrogen into the NTS and the implications for the wider gas network, including interconnectors, storage, Liquified Natural Gas (LNG) etc.
  • Highlight the impact on the network, including materials, instrumentation, hazardous areas etc. It will also assess the end user impacts such as appliances, in particularly safety apparatus including oxygen depletion systems (ODS) and various other sensors.
  • Development of an emission performance chart for hydrogen production.
