One of the major problems that the modern society faces is the energy source deficiency or simple fuel deficiency. The reduction and shortage of fossil fuels forced the world to think about the alternative solutions like non fossil fuels. The fuel consumption and usage along with the concept of sustainable development forced the world to think about the non polluting fossil fuels. The most popular and widely used fuels like petrol and gasoline have imparted a great pollution rate to the environment. The government has initiated their move to shift the use of petrol and gasoline to CNG. CNG vehicles and CNG filling stations have been introduced as a part of it to reduce the increased emission rate. Now considering the aggravated position of pollution in Indian society the Indian ministry of road and transport has initiated the switching of CNG to HCNG which has a lesser emission rate compared to the CNG. For this move the Ministry has issued a release for welcoming the HCNG use in vehicles as fuels. For this practical implementation the ministry is ready to amend the Central Motor Vehicle Rules 1979 to incorporate the facility in legal terms. In this scenario let us look into the feature difference and impact of the Compressed Natural Gas (CNG) and Hydrogen enriched compressed natural gas (HCNG) in detail.
Comparison and Overview of CNG V/S HCNG
| CNG | HCNG |
| It is the abbreviated form of compressed natural gas | It is the abbreviated form of Hydrogen enriched compressed natural gas |
| CNG is made by compressing natural gas mainly composed of methane | Is a mixture of compressed natural gas and 30% of hydrogen by energy |
| Lower emission rate carbon monoxide and other compounds | The emission rate will be 70% less than that of CNG |
| Compressed natural gas (CNG) refers to natural gas compressed to about 200 to 250 bar. | It requires only a small hydrogen storage and a column for the mixing of hydrogen with natural gas at existing CNG stations. |
| Dielsel and Gasoline vehicles need to be converted to CNG compatible vehicles
|
Safety components are similar to the CNG. HCNG is easier and safe to use than hydrogen as it contains very low energy content from hydrogen i.e., up to 30% by volume. |
| Environment Friendly and safer | HCNG reduces the engine’s unburned hydrocarbon emissions and speeds up the process of combustion. |
| Low cost. It has lower cost compared to the petrol and diesel and thus it can in effect reduce the overall cost of everything of our country | The engine’s fuel efficiency is improved by blending the CNG from hydrogen which lowers the fuel consumption of the vehicle. |
| Easily Maintainable | The thermal efficiency and fuel economy is also increased by HCNG. |
| There are many CNG stations and it is easy to set up a CNG station but requires a decent amount of investment. | HCNG storage and supply infrastructure is a big challenge |

Indian Development on HCNG
1: Who was the first woman President of India?
HCNG is a future fuel. India hopes to have full implementation of HCNG fuel equipped machineries and vehicles in near future. At present only few countries in the world have this technology. In Indian scenario the background of development on HCNG lies from the period of 2016. Confederation of Indian industry in partnership with Niti ayog has launched the clean air better life initiative in November 2016. As part of the initiative they formulated four task forces namely task force on clean fuel, task force on clean transport, task force on clean industries and biomass management. Among them, the task force on clean fuel has formulated an action plan for clean fuel and submitted a report. In this report they have suggested the demonstration of the HCNG project at one DTC depot. Subsequently the Indian Oil Corporation Limited (IOCL) has acquired the patent for the production and HCNG has been developed. The ministry of road and transport has amended its rules 1979 for accommodating the HCNG equipped vehicles for transport. And thus Delhi is witnessing its first HCNG equipped bus voyage on 20 October 2020. Hope that many excavations and developments may happen in near future in regard to HCNG.
