A joint venture (JV) between the governments of Sweden and Delhi will convert biogas from Keshopur sewage treatment plants to compressed natural gas (CNG), purportedly the first such project undertaken in India, reports Indian Express. The biogas will be generated at sewage treatment plants and utilised to run buses owned by Delhi Transport Corporation (DTC). Delhi is said to have the largest fleet of CNG-run buses in the world. Approved in-principle, the project is set to begin by September 2011.
The project is being spearheaded by the Efficiency and Renewable Energy Management Centre, managed by state-designated company Delhi Transco Ltd. Costs will be shared 50:50 between the Delhi government and the Swedish International Development Cooperation Agency (SIDA).
The Delhi government began talks with the Swedish government last December, following which Swedish experts conducted a three-month study of four sewage treatment plants in Delhi — Dwarka, Keshopur, Coronation Park and Okhla. Successful implementation may see many of the city’s 17 sewage treatment plants receiving renewable biogas facilities, subject in part to distance to nearest infrastructure to enable integration of supply.
Biogas will also be reportedly be generated from vegetable waste from the local Keshopur markets.
Sweden is a pioneer in the waste-to-energy sector. The project is part of the MoU signed between the Swedish government and India in 2009 for work on this sector.
