Indian Railways is working on technologies that will enable 40% substitution of diesel by compressed natural gas (CNG) in locomotives and nine-zoned solar panels on diesel electric multiple units (DEMUs). The move will help railways achieve its ‘Mission 41K’ target and reduce carbon footprint. The development comes close on the heels of railways flagging off a solar-powered DEMU, a six-coach rake, which is expected to save 21,000 litre of diesel annually, translating to savings of Rs 12 lakh, and also cut carbon emission by 9 tonne per year. Such initiatives are expected to help it save Rs 41,000 crore in the next 10 years called ‘Mission 41K’ as envisaged by railway minister Suresh Prabhu earlier this year.
Railways recently floated a tender inviting applicants to work on its diesel locomotives and develop systems that will ensure that 40% of diesel is substituted by CNG in a standard duty cycle of a DEMU, as specified by the Research Designs and Standards Organisation, a wing of railways.
“The tender specifies the engine to be worked upon in which the applicant will use the CNG substitution system. We have given the emission standard, the duty cycles are mentioned and we need 40% substitution,” said an official of the railway ministry. Read More…
