Extensive commercialisation of hydrogen vehicles is very much possible by the mid-21st century.
Hydrogen as an energy source is widely touted to be the future transportation fuel.
Access to hydrogen fuel stations is limited to a population of 250million worldwide, with only 6,500 such cars globally. HCNG fuel (with 18-23% H2 blended with compressed natural gas) can beused in existing CNG vehicles with minor modi?cations. Nationwide awareness programmes and vehicledemonstrations in collaboration with vehicle manufacturers and research institutes could allay people’s concerns to some extent. Developing safety regulations and codes for hydrogen storage, transportation and fuelling is another area that requires considerable
attention. Extensive commercialisation of hydrogen vehicles is very much possible by the mid-21st century.
