50 city buses to run on HCNG on trial, HCNG likely to achieve a significant reduction in vehicular emission

Shri Dharmendra Pradhan, Union Minister of Petroleum & Natural Gas and Steel, inaugurated IndianOil's compact reformer plant and launched the much-awaited trial run of Delhi's buses on Hydrogen-blended CNG (HCNG) here  today at the Rajghat Bus Depot-I of DTC. In India's quest to promote Hydrogen as a clean fuel for the mobility sector, Hydrogen-blended HCNG is emerging as an excellent interim technology for achieving emissions reduction and import substitution. Refueling of H-CNG blends in vehicles can be performed with minimum modifications in the infrastructure that is currently under use for dispensing CNG. Shri KailashGahlot, Minister of Transport, Government of Delhi, was also present on occasion.

Speaking on the occasion, Shri Pradhan said that providing clean and reliable energy supplies to 130 crore plus Indians is the top most priority of the Government.  He said that India will emerge as a winner in developing the solutions, the world would admire for the decades ahead. The Minister mentioned that Prime Minister Shri NarendraModi is committed to usher in clean energy future that has minimal impact on the environment. Complimenting the initiatives of IndianOil, the Minister said, "I am happy to note that the scientists of IndianOil R&D have risen to the occasion and have developed an innovative compact reforming technology for production of Hydrogen-mixed CNG." Elaborating on the importance of Hydrogen in facilitating India's energy transformation, Mr.Pradhan mentioned, "Hydrogen is the ultimate fuel, which, while giving energy, produces clean water in the emissions. Apart from this, it has many other virtues as the capacity to get the rural sector involved with the energy sector through biomass". The Minister said that this pilot project will be unique. It will help the county and the world as a whole.

Transport Minister of Delhi Shri KailashGahlot appreciated IndianOil’s efforts to develop such a path breaking technology not only for the first time in India but in the entire world. He said  that this project has been executed in cohesive environment involving IndianOil, IGL, DIMTIS, DTC and Delhi Transport Department. He assured of Delhi Government’s full cooperation for the successful completion of the trial, so that this fuel can be commercially adopted soon on pan  Delhi and India basis.Shri Gahlotcomplimented the team work of all stakeholders. He spoke about its usage not only for DTC buses but also for private buses, once its trial is over.

The Secretary, MoPNG, Shri TarunKapoorsaid that HCNG is the fuel of the future. He said that HCNG is produced in much way all over the world but its commercial viability is the main challenge. Shri Kapoor mentioned that production of HCNG in India would be very cheaper and this will reduce the burden over Gas imports.

Speaking on occasion, Shri S M Vaidya-Chairman-IndianOil, said that the latest technological development would augur well with the nation's vision & commitment to transit towards the hydrogen economy. Talking about IndianOil's pioneering work in hydrogen research, Mr.Vaidya said, "IndianOil took early steps in promoting Hydrogen initiatives. We also launched a research program on HCNG alongside the Society of Indian Automobile Manufacturers (SIAM) and MNRE. IndianOil has set-up two Hydrogen and HCNG dispensing stations: one at our R&D campus in Faridabad and another at our retail station at Dwarka, Delhi". He expressed hope that more partnerships will be formed.

An audio video film was also shown on the occasion. The message of Shri BhureLal, Chairman Environment Pollution (Prevention & Control) Authority for the National Capital Region (NCR) was also played on the occasion.

A brief on IndianOil's patented H-CNG Production Technology

Globally, Hydrogen required for blending in CNG (Compressed Natural Gas) is produced through electrolysis of water, followed by high-pressure blending with CNG. This process's high cost offsets the savings achieved from fuel economy gains compared to baseline CNG.

In India’s continuous quest to use hydrogen as a fuel for the mobility sector, hydrogen blended CNG (commonly called H-CNG) has emerged as an excellent interim fule for achieving emission reductions and import substitution. The existing IC engine without any significant modification can be run on H-CNG and with minimal infrastructural upgrade, the existing CNG dispensing refueling infrastructure can be used to deliver H-CNG blends as well.

• H-CNG blends can be produced directly from CNG, bypassing the energy-intensive electrolysis process and high-pressure blending costs.
• The flexible and robust process allows the production of H-CNG on-site, in less severe conditions, and under low pressure
• It provides a higher yield H-CNG mixture by up to 4% to 5% compared to CNG's input quantity.
• The cost of H-CNG production by the above process is about 22% cheaper than conventional physical blending.
