KEY POINTS

·         The transport sector in India contributes one-third of the total greenhouse gas (GHG) emissions, within which the lion’s share is that of road transport.

·         The new H-CNG technology requires only minor tweaks in the current design of CNG buses. Although the current pilot phase of H-CNG buses is a step in the right direction, it should perhaps be considered as a stop-gap arrangement, at least until a cost-effective variant of green hydrogen blended fuel is discovered, which would address emission mitigation and will also be more economical.

·         In the case of green hydrogen, electricity generated from renewable energy is used to split water into hydrogen and oxygen. This is by far the cleanest and perhaps the most expensive method of producing hydrogen at the moment. Majority of the hydrogen production in India takes place via fossil fuels and is used primarily in the chemical and petrochemical sectors.

·         It is equally important to take cognisance of the fact that not all aspects of hydrogen as a transportation fuel paint a pretty picture. For instance, the cost of lithium ion-based battery-operated vehicles has been reducing while hydrogen fuel cell technology is still in its nascent stages and is relatively quite expensive.

·         To put things in perspective, this implies that a hydrogen-run vehicle achieves an energy efficiency rate of 25-35%, which may vary based on the model. This analysis has been conducted with regard to passenger cars, and the results may differ in the case of heavy-duty vehicles.

·         In their quest for becoming carbon neutral by 2035, Reliance Industries plan to replace transportation fuels with hydrogen and clean electricity. Similarly, the National Thermal Power Corporation (NTPC) is considering setting up a green hydrogen production facility in Andhra Pradesh.

 

·         As per a policy brief issued by TERI, demand for hydrogen in India is expected to increase 3-10 fold by 2050. Against this backdrop, the future of hydrogen, particularly green hydrogen, looks promising in India.
