A couple of points :
(1) Hydrogen flame has no colour , but for burning it needs oxygen. if there is no Air/ oxygen , obviously combustion can not take place
(2) Grey Hydrogen usage is age old practice in various Industries…and now these industries are turning to Green hydrogen with targeted time lines for decarbonisation. This is rapidly taking place.
(3) Green hydrogen to Electricity conversion for feeding to grid initially faced challenges due to inadequate electrolyser -Fuel cell manufacturing capacity- now it is overcome with alternate energy storage solutions such as BESS, pumped hydro storage etc.
(4) Automobiles-though Fuel cell technology is sound and proven…adoption is slower due to few reasons :
(a) Hydrogen infra – handling storage and filling stations. China takes the leadership with 250 Hydrogen filling stations , Japan no 2 with 160., though Japan Toyota Honda pioneered Fuel cell.
(b) Cost of Green hydrogen currently high , but expected to come down with scale.
(c) Fuel cell is expensive due to rare earth elements like platinum…But again newer Technology development can identify cheaper material.
(d) Though Hydrogen technology is few decades old, but it did not receive much attention that it deserved. Now that the theme is climate change and the entire globe is in to it…it should move
(5) The other more practicable solution alternate to Fuel cell is hydrogen IC engine vehicle for a country like India.
The century old petrol diesel IC engine platform remains as it is with some changes in material composition. the same set of existing Auto ancillaries can cater to OEM’s
Hydrogen when used as IC engine fuel can give off H20 only in exhaust with Zero carbon… The only issue is NOx – nitrogen from air in the combustion process. But this can be handled very well as we do in petrol diesel engine.
Cost of hydrogen IC could be lower than fuel cell…so almost all auto OEM currently working on Hydrogen IC apart from Fuel cell.
Apart from all our Auto OEM in India , other MNC’s those who have developed hydrogen IC are MAN, Komatsu, BMW, Honda, JCB, Toyota, Hyundai, Volvo, Volkswagen and Renault Group.
