Battery operated EV’s may be the immediate need of the hour, but can not be the final solution for Zero carbon emission for reasons mentioned in my previous posts.
World over now the emphasis is on Green Hydrogen to be used
as an Automobile Fue as the final combustion product is steam. (Green Hydrogen is derived from electrolysis of water - Electricity power used should be from renewable sources wind, solar)
Currently two major industries namely Fertiliser plants and Refineries are the major consumers of hydrogen produced in India / World.
These are not green Hydrogen…these are all produced from hydrocarbon fuel or coal resulting in to carbon emissions.
So the immediate mandate for all Refineries and Fertiliser Plants who consume Hydrogen is to produce Green Hydrogen- at least to counter carbon emissions at their plant locations- it appears from different announcements by Oil PSU and Others - so actions/ efforts/ commitments are definitely there.
Now let us come to Automobiles, Green hydrogen can be used in automobiles in 2 ways:
(1) Internal combustion engines- code named as H2- ICEV.
It would burn Hydrogen fuel in stead of petrol and diesel. While there is no carbon emissions from tail pipe, but since air is used to burn Hydrogen and air contains 77 % Nitrogen , so nitric oxide will be an emission which is a pollutant. And there will be some lubricating oil getting burnt in combustion chamber, so to that extent some carbon emissions would be there. Therefore green Hydrogen used as a ICE fuel is not zero emission vehicle .
(2) Fuel Cell vehicles code named as H2- FCEV is the ultimate the world is looking for !
In a fuel cell vehicle , the hydrogen is not burnt…Hydrogen is used along with oxygen from air to produce electricity in an electrolyte medium with a cathode and an anode…
This electricity so produced would drive an electric motor which in stead would drive the vehicle. (This is just the opposite of electrolysis of water by using electricity to produce hydrogen)
There are no huge batteries required (one small battery may be required for only starting )…Recharging with hydrogen needs to be done…just like fuel topping.
This is Zero emission vehicle and this is the ultimate vehicle perhaps the world is aiming at.
Yes available in both versions and sold commercially.
So what is not available is the Hydrogen infrastructure.
Attaching the following articles which would give you a lot of insights on Hydrogen as Auto fuel and would be helpful for your investment journey.
(1) 5 Reasons why you would prefer a Hydrogen Vehicle ultimately and 5- reasons why you would prefer an Electric vehicle now.
(2) H2- ICEV
(3) H2- FCEV
(4) India’s Hydrogen journey 2006-2021 and where are we now and will we expedite our plan in to action ?
Discl: it is not an investment advice…it is purely for information and education purpose
@1957 If this thread is about hydrogen, why don’t you give a more meaningful heading like “Hydrogen - the ultimate Green Fuel” or something similar so that anyone searching for information on hydrogen as a fuel will find it more easily?
Thanks for your good suggestion! Already done !
Actions being taken in Hindsight!
Delhi , being the capital city of India, it draws media attention very fast…But in reality there are many cities in our country are facing severe air pollution.
While this is a 4 month old article , but some of you would have missed this…
This is to say that Hydrogen Fuel cell vehicle is the new reality whether it is a car or a Bus…No need for a Lithium battery and No need of Recharging ! The only charge required is Hydrogen Gas which needs to be topped up just like petrol or diesel vehicle !
The hydrogen reacts with oxygen from air to generate electricity on board which drives the Motor which inturn drives the vehicle
Since there is no combustion … so No CO2, No Nox, No HC , No PM, No RSPM…
While this is only a pilot lot for trial purpose and Tata motors is yet to supply these buses…I don’t think there would be much contribution from Hydrogen Cell vehicles for next 2-3 years from business point of view…until hydrogen infrastructure is ready.
Discl: not an investment advice…only for education and information purpose
Belgian Researchers develop Solar Panels that produces Hydrogen. The photovoltaic cells in the very special Solar panel produce electricity which in turn takes water vapour from moisture in air to split it in to hydrogen and oxygen…
How wonderful discovery…Hope it will help commercial production…
And in another Development -
Roof top solar is now a Passe ! Solar power is getting cheaper day by day. Storage of electricity so produced is expensive ! If you want to sell solar power so produced, it would no longer be commercially viable.
Now look at Roof Top Hydrogen. You fill a chamber of “the roof top hydrogen device” with water. The next day, your cylinder or tank is full of Green Hydrogen — a Green fuel for your car or the cook stove.
So it is not to say that Solar power will no longer be produced…but very soon , Roof top Hydrogen would also become very popular !
At several places, research is on to see how soon this can be produced commercially.
John Cockerill is also listed in India
The main challenge is to reduce costs, Reliance has taken the 1-1-1 challenge, where it will reduce costs to US$1/kg in 1 decade. Apart from this, storage and transportation infrastructure requires right government policies and massive investments,
Source:An idea whose time has come...
I think, we in India are moving very fast with regards to Green Hydrogen and so we may be able to reach the target much faster than other countries…
To produce Green Hydrogen, we need more and more Renewable sources such as Solar/Wind/Hydro…and we are firing all these three cylinders …currently…
I can see there are clearly 5- strategies evolving !
(1) All Fertiliser companies and oil refineries including Oil PSU’s have been instructed not to use Grey / Blue Hydrogen for their Hydrogen requirement …so these companies have already started work on Green Hydrogen for which they need to commission Solar / wind power to produce electricity which in turn will be used to split water to green hydrogen …
(2) Need of the hour is clean Air in our cities … and so EV is evolving…
(a) The batteries are being charged by electricity produced by Fossil fuels … such as Coal (currently 72% of total electricity in India) Which emits a lot of carbon emissions in to our atmosphere …So until we reach our renewable power target , EV is not solving our carbon emission / air pollution issue.
(b) Lithium Ion batteries are costly …there are only very few countries such as Chile, Australia, Argentina where lithium mines are available and cobalt required for Li ion batteries are sourced from only one country - Congo.
(3) Automobiles: Future plan is to.use Green hydrogen fuel to be used in automobile fuel in ICEV / Fuel cells- technology is available …vehicles are being produced in both modes…so here again Renewable sources of energy is required…to produce green Hydrogen and of course the Hydrogen infrastructure has to go a long way … however, when there is a will…there is a way…Look at the growth of CNG/ PNG infrastructure during last 7-8 years.
(4) For domestic electricity, we may have all kinds of options …roof top solar, roof top wind, solar /wind hybrids, roof top hydrogen etc …
(5)Li Ion Storage Battery:
With implementation of Green Hydrogen for Automobiles, we can do away with Li ion Batteries…However, Storage Battery will still be required for Domestic use and at solar and wind mill plants…
At the same time, Lithium and Cobalt are rare commodity …and we have to depend upon other countries …currently China is taking advantage of our need and supplying Li Ion batteries. All of a sudden , If China would increase the price of all raw material, then we would be hit …( it happened in case of pharma and speciality Chemicals recently when China increased cost of KRM all of a sudden). The same thing is happening with semiconductor issue across the world…and we are yet to come out of this …so the lesson is don’t depend upon Rare commodity, and rare elements for our technology need.Keep it simple and try to use the resources which are available in plenty.
No wonder , we are trying to buy out lithium mines outside India …
But China is ahead of us in their strategy … .they have the first movers advantage in EV technology and they do have very small capacity lithium mines …though not sufficient for their requirement … and cobalt they have to buy from Congo…
China wants to be self reliant in storage battery …so they are trying to do away with lithium ion Batteries. …
They have already produced Sodium Ion Batteries … Sodium and Lithium being neighbours in periodic table in Chemistry…they have similar properties…Sodium is plenty on earth … can be produced from soda ash…from sea salt water…
under PLI scheme , a lot of well known players have applied …though all are are for lithium ion batteries …but we can always do our own research for sodium ion batteries …and we don’t need cobalt for sodium ion batteries …what we need is Iron and manganese…available plenty in our country.
If you want to know more on the subject , I am giving you some links which would be quite educative and informative …
