Study reveals new solution in battle against emissions - IBTimes

A study published by the National Grid in the UK is suggesting that Bio-SNG (Synthetic Natural Gas) could achieve carbon dioxide (CO2) savings of up to 90 per cent compared with fossil fuel alternatives.


The report, prepared by Progressive Energy and CNG Services, shows that unlike biomethane produced by anaerobic digestion Bio-SNG is formed by the conversion of thermally derived syngas into methane. Feedstocks can also include more durable materials such as woody biomass and wastes that are not broken down in traditional anaerobic digester plants.

It states that biomethane retains all the attributes of natural gas with the advantage that the fuel is renewable, which means there are substantial carbon dioxide savings. However, in order to achieve a step change in production capacity alternative approaches such as thermal routes are necessary.

Among the conclusions of the report are that implementation of Bio-SNG will only occur with the appropriate tax, incentive and legislative environment; and that it is likely the development of Bio-SNG facilities would require the developer to go upstream into the supply chain for both grown and waste derived fuels.

A process and technology review found that the major process operations required to produce Bio-SNG can be identified and assembled from existing technology suppliers; while a full lifecycle analysis of Bio-SNG production found that for many types of feedstock the savings of Bio-SNG compared with fossil fuel alternatives are as high as 90 per cent.
