Trial run of Delhi’s buses on Hydrogen-blended CNG (HCNG) launched

The trial run of Delhi’s buses on Hydrogen-blended CNG (HCNG) was recently launched.
Under the Ministry of Petroleum & Natural Gas.
HCNG is a hydrogen-enriched compressed natural gas (CNG).
In Delhi, instead of physically blending hydrogen with CNG, hydrogen spiked CNG will be produced using compact reforming process patented by Indian Oil Corporation.
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.
Mixing hydrogen with CNG physically is a difficult proposition and that is why IOCL came up with the compact reforming process, which reforms CNG and there is no need for mixing.
