2 What is Bio-substitute natural gas? Definition Biomethane produced by gasification or pyrolysis of biomass. Biomethane is a mixture of gases meeting grid entry requirements. Gasification is substoichiometric oxidation or steam reformation of a substance. Pyrolysis is thermal degradation in absence of external oxidising agent.

12 Large Scale Commercial Plant APP and partners now beginning to develop large scale plant 15 x larger than demonstration 320GWh of BioSNG production per annum. Development RTFC offer good levels of support for BioSNG used in transport. Currently identifying sites and development partners. Seeking transport partners interested in long term CNG/LNG off-take.

13 How Could an Entire City Convert to Low Carbon Gas? What feedstocks wastes and residues can be used to make the gas? How many gas generation facilities are required? Where would the gas be injected into the network? How reliable are green gas plants? How will the gas network adapt to ensure green gas is delivered to customers reliably? How will a constant supply of gas be matched to a highly variable demand? How will networks be managed when gas supplies are variable? What is the cost to consumers?

14 BioSNG Cities Project Coventry and Edinburgh selected for detailed analysis. Current gas demand will be analysed to determine number and scale of green gas facilities. Review city plans to determine possible locations for green gas plants. Carry out detailed modelling of supply of green gas to homes and businesses to identify modifications required to ensure reliable gas supply. Estimate storage requirements to handle diurnal and seasonal variations in demand and analyse options for storing gas. Calculates costs of decarbonising each city and analyse options for socialising these costs.

15 Expected Results A plan to decarbonise Coventry and Edinburgh s gas networks. An outline of changes to current network designs required to support distributed gas production. New procedures to manage gas networks with multiple points for gas injection. A plan for storing gas to smooth diurnal and seasonal variations in demand. An estimate of the capital and operating costs of a green gas network and the cost to consumers. The recommended mechanisms for socialising the costs such as feed in tariffs, an obligation on gas suppliers or grid regulation.
