BIOMETHANE UPDATE
![Page 7: Bio-CNG from Crewe - 25th June 2014](https://reader035.vdocuments.net/reader035/viewer/2022062412/579090c71a28ab7b278dfdb6/html5/thumbnails/7.jpg)
Annual Biomethane to Grid and RHI for 2012-2015
2 TWh of gas = 68 million therms = 136 million kgEquivalent to around 180 million litres of diesel
![Page 8: Bio-CNG from Crewe - 25th June 2014](https://reader035.vdocuments.net/reader035/viewer/2022062412/579090c71a28ab7b278dfdb6/html5/thumbnails/8.jpg)
Benefits - CO2 Impact
• Forecast 1.8 TWh injected into gas grid in 2015
• 130,000 tonnes of gas
• 130 x (44/16) = 360,000 tonnes of CO2 saved at the burner tip
• Marginal gas to UK is Qatar LNG
• The 130,000 tonnes of biomethane displaces 130,000 tonnes of LNG– 15% higher CO2 than UKCS gas on a “Well to Tank” basis
– 7-9% CO2 vented in Qatar
– So around 50,000 tonnes on top
• So, around 400,000 tonnes/annum benefit
• Material contribution towards 2020 renewable energy targets

Benefits – Using the Gas Grid
• UK has great gas grid– 85% of domestic market connected to
grid
– 95% of industry
– Power generation back up to wind
• To build gas grid and central heating etc would cost around £100 billion
• Vital UK asset
• All our Grid Owners are very supportive and have created an attractive regime to allow projects to go ahead at lower cost/quicker

CO2
![Page 25: Bio-CNG from Crewe - 25th June 2014](https://reader035.vdocuments.net/reader035/viewer/2022062412/579090c71a28ab7b278dfdb6/html5/thumbnails/25.jpg)
CO2 Summary
• Dual fuel diesel-CNG offers around 10% ‘tank to wheel’ CO2 saving over diesel
• Dedicated CNG should be 20% saving– Theoretical 28% saving, less inefficiency of around 8% of spark ignition
engine
• Using biomethane instead of natural gas in a dual fuel truck gives saving of around 60% saving in ‘Well to Wheels’ compared to diesel (“Bio-CNG”)
Move to CNG aimed at Heavy and Medium Goods Vehicles with high mileage and emissions
