One up in CNG? Delhi prepares to mix hydrogen in 50 buses

NEW DELHI: Nearly two decades ago, the public, cars and taxis in Delhi had to switch to a cleaner fuel, from diesel to, following a Supreme Court order. Again, it is a direction of the apex cut that will introduce a better fuel, the CNG enriched with hydrogen (HCNG), into the.



As of November of this year, 50 buses under the cluster scheme will begin to use HCNG as part of a pilot project. On Thursday, Indian Oil Corporation Limited (IOCL), which has developed the technology to produce HCNG, and Indraprastha Gas Limited (IGL) laid the foundation stone of a four-ton reformer-based compact production plant per day in Rajghat -1 station of the Delhi Transport Corporation (DTC).

Following the directive of the apex court last July, IOCL and IGL have collaborated to install this first semi-commercial plant to carry out a study on the use of HCNG in 50 buses that run on CNG from Anthony Road Transport Ltd, a concession group. The plant, which will be ready in October, will be launched in November.

Compared to the physical combination of CNG, the usual reform process around the world, the compact reform process is 30% more profitable, said an IOCL spokesman. The current buses that run on CNG can easily run on HCNG with just a little adjustment, he added.

S S V Ramakumar, director (R u0026 D) of IOCL, said the work had lasted almost a year. Mixing hydrogen with CNG physically is a logistical nightmare. The compact reform process reforms the CNG and there is no need to mix, he said. The efficiency and emissions of the 50 buses will be registered for six months and will be presented to the Supreme Court.

Sunita Narain, a member of the Environmental Pollution Prevention (Control and Prevention) Authority (EPCA) said at the event that when the EPCA had suggested the introduction of CNG in public transport vehicles in the late 1990s, Many interested parties opposed it. By 2020, he stressed, the CNG will look like the fuel of the past and the HCNG is more conducive to conditions in India and will help generate a hydrogen economy.

There was a misinformation campaign at the time and it was said that vehicles that use CNG would explode and that each vehicle would become a bomb, Narain said. He pointed out that instead of going directly to pure hydrogen, which is much more expensive, it is better to switch to HCNG, which will maximize the use of the infrastructure already available for CNG.

E S Ranganathan, managing director of IGL, said that while four tons of HCNG would be produced at the plant every day, any excess fuel would be used to run a generator to produce electricity.

On the price side, Ramakumar said it might cost a few paise more than the CNG initially, but once production increases for more buses, the cost will go down.
