Green Hydrogen- The ultimate Green Fuel- Indian companies that are leading the Green revolution in India!

Anything newly developed may involve safety issues , but then it is a part of new technolgy evolving process.
When CNG buses were introduced in 2000, several CNG Buses caught fire at initial stages . But the design thereafter was made robust. The CNG pipe line joints were made leakage proof. It is no longer considered a safety issue.

But Hydrogen fuel vehicles design is almost 20 years old. It is new. Only thing is it was not mass produced in large numbers due to cost reason. If we are targeting Green Hydrogen to cost 1 USD a Kg, then both Hydrogen fuel cell and Hydrogen IC engine could be a reality as mass production

Adani in pact with Ballard for Hydrogen fuel Cells

Hydrogen fuel cell would be used for producing electricity which would drive Automobiles. No need of any battery.

Hydrogen fuel cell can also be used to produce electricity from Green hydrogen at renewable sites of Solar, wind hydro

Only two companies namely Reliance and Adani are two pvt sector companies who have declared for betting on the entire renewable value chain of Renewables - solar / wind, Green hydrogen , Hydrogen Fuel cell. Reliance is also in to Sod ion batteries.
Tata Power is another player who is in to Solar/wind, Yet to announce for Green hydrogen and fuel cell

An interesting take on some ratios demonstrating hydropower has best ratio if we are looking at green or environmental friendly. According to this article hydrogen is negative or not eco friendly.

Green Hydrogen (GH2) - The Next Frontier of Energy?

Hydrogen is slowly emerging as a key source of fuel for the future. Green hydrogen (or GH2) has attracted a great deal of interest from AA (Ambani-Adani). Mukesh Ambani started off with an announcement of $10bn into green energy which was upped by Gautam Adani at $20bn. Ambani then announced a $75bn investment in the entire ecosystem of electrolyser manufacturing to solar panels.

ACME just announced a 52K cr investment in India. GAIL is getting into manufacturing electrolysers, Oil India is looking to build a GH2 plant in Assam, and NTPC is looking to set up H2 fuel stations across India.

This is an effort to understand at a very high level and in simple terms what the whole GH2 is all about.

The Green Hydrogen Opportunity

India plans to manufacture around five million tonnes of green hydrogen per annum by 2030 according to the power ministry.

Solar and other forms of renewable energies are now available at cheaper rates in India, making producing green energy a cheaper and climate-sensitive decision.

Green hydrogen energy models are substituting coal in the steel industry. With shortages of coal across the country the demand for green hydrogen might increase.

Green Hydrogen is expected to capture the fertiliser production to substitute natural gas.

Customers of green hydrogen arise from various industries. Steel, Fertilisers, Transport, retail consumption etc. India has the highest growth in demand for energy resources and green hydrogen has the potential to meet the market needs.

Industrial Gas (IG) companies have core competencies in managing networks, distribution, providing storage, liquefaction technology, and the ability to sell oxygen that will be generated along with hydrogen and backup supply.

Hydrogen Fuel

  • Hydrogen fuel is a clean fuel alternative whose by-product is only water and not CO2
  • It can act as a carrier to deliver energy from other sources
  • Can be produced from Natural gas, Biomass, Nuclear power and renewable energy like sun and water.
  • Can be categorised into grey, blue and green hydrogen based on the carbon emission incurred
  1. Grey Hydrogen: production results in emissions of large volumes of Carbon dioxide. Produced from natural gases and are widely used as of now.
  2. Blue Hydrogen: A cleaner version whose carbon emissions can be stored or reused,
  3. Green Hydrogen: Pure fuel which emits no carbon and is energy efficient. However, it is expensive to produce and store due to its highly inflammable nature.

Green Hydrogen Production Process\ 650xauto
Green Hydrogen Production Process

Production Methods:

Electrolysis

  • Creation of hydrogen from water by passing a current through an electrolyser.
  • Expensive process

Thermal Processes

  • Steam reforming where steam reacts with hydrocarbon fuel to produce hydrogen
  • Hydrocarbon fuels which can be reformed include natural gas, diesel, renewable liquid fuels, gasified coal or gasified biomass
  • 95% of hydrogen is produced by reforming Natural gas.

Biological processes

  • Uses microbes such as bacteria and green algae to produce hydrogen
  • Microbes surviving and feeding off of wastewater produce hydrogen as a by-product.
  • In photobiological processes, the microbes use sunlight as the energy source.
  • Expensive and limited resources available

Solar processes

  • Using light to produce hydrogen
  • Photobiological as explained above
  • Photoelectrochemical processes use specialised semiconductors to separate water into hydrogen and oxygen
  • Solar thermochemical hydrogen production uses concentrated solar power to drive water splitting reactions often along with other species such as metal oxides.
  • Present technology doesn’t facilitate large-scale production using this method.

Pros and Cons of Hydrogen Fuel

Pros of using hydrogen fuel

  • Renewable
  • Readily available
  • Zero carbon byproduct meaning it doesn’t harm the environment
  • More powerful and efficient compared to traditional fossil fuels
  • No noise, visual pollution

Cons of using hydrogen fuel

  • Infrastructure to transport highly flammable hydrogen
  • Extraction of hydrogen
  • Costs involved
  • Regulatory issues
  • Storage

Use of Hydrogen Powered Vehicles

Hydrogen cars require a generator within the chassis to bring the rotational movement whereas in the case of EV the battery provides the charge required to move directly. The reason why hydrogen cars are less popular is because of the same reason. In future, hydrogen can be used to produce the electricity used in EVs

Commercial Uses

Commercial uses of hydrogen can be seen in

  • Health Care, Food and beverages - hydrogen is required in medicines and pharmaceuticals. Example hydrogen peroxide and the creation of margarine and similar foods, where unsaturated fatty acids are hydrogenated from oils to form a solid product.
  • Metallurgy - in production processes of steel, and aluminium.
  • Space operations require higher power which is provided by hydrogen
  • Power Generation.

Summary

Green hydrogen is the fuel of the future. It only produces water as a by-product. It is renewable but requires fossil fuels and coal for the separation of hydrogen.

Research is now being done to eliminate the requirement for fossil fuels in producing hydrogen fuel.

Not able to see RIL or Adani here, maybe their plan would be added later. Surprised to see a huge number by Hero Future energy. Did some basic checks and found that this Munjal group company was founded in 2012 and has interests in renewable energies like Solar & Wind so far. Battery & Storage is also an interest area.

I am not sure if this is a subsidiary of Hero parent group or comes under listed Hero Motocorp as I am unable to find confirming evidence on any. Would be great if you or anyone else can share insights on this subsidiary, its parent and if listed company holds it. Thanks

RIL & Adani both are definitely there in the entire cycle of Green hydrogen manufacturing, though the PSU’s are very fast in adopting as there is Govt mandate to meet carbon foot print and especially the Oil and Gas PSU’s are the ones who are currently consuming a huge amount of Grey/ Blue Hydrogen being produced for the refinary needs and fertiliser plants.

Regarding Hero future energy - it is a pvt limited company , a part of Global Hero energy group , nothing to do with Hero motors.

Bahadur Chand Investments Pvt Ltd (BCIPL) and Brij Mohan Lall Om Prakash (BMOP)- These two companies indirectly hold the entire Hero group’s stake in Hero Future energy Pvt Ltd.
As and when the company gets listed , it would be another listed renewable energy pvt players like Reliance, Adani & Tata…Not to forget about L&T , who is silently working on renewable energy and Green Hydrogen.

Fuel Cell EVs seems much more of a tough nut to crack and maybe it’s hard to replace BEVs but only co-exist with it. Quite a number of things go against Green Hydrogen be it manufacturing, liquifying it, transporting, less efficiency, highly flammable . Also setting up the fuelling stations cost much more than an an EV charging station. This seems much more of an logistical and for the foreseeable future economical nightmare too. Green Ammonia industry is still in nascent stages to be called the carrier for hydrogen.
Till the time technological and infrastructural developments happen in (GH2) we may see next gen BEVs stepping up their game which they are already doing with technological improvements

Reading a few research reports , it seemed as if a good alternative for heavy vehicles which can’t be electrified because to have a fuel cell system you need a certain minimum amount of components, and the size is generally the same. But this article throws some light on that as well.
Though agree with the part of coal being the source of electricity in BEVs, perhaps now hydrogen seemingly has too many limitations to replace it . The twin challenge remains not only to ramp up GH2 supply by subsidizing, giving PLI to producers, investing in a whole grid but also creating a feasible demand for the end consumers. The costs are enormous. Starting today ,the infra required for distributing and making hydrogen on this scale would take 2-3 decades. Quite confused over the hype of hydrogen on road transport.(especially light vehicles)

Some more nuances:

Hydrogen fuel Cell vehicles and Hydrogen for IC Engines Vehicles may be a small part of the entire Green hydrogen game plan, which to begin with may go side by side along with EV for quite sometime due to complexities involved. But the science comes out with solutions - if Green hydrogen is the ultimate goal.

However, there are many othe carbon producing industries such as power plants, fertilisers, Petroleum refining and many others where Green hydrogen theme is playing out very fast- it is not at all a hype.

It is because if we look at the big picture on climate change, Global warming , Ozone layer depletion , the entire Globe is looking towards the Carbon foot print- there is no denying and all the nations are coming together to unanimously agree only one Goal , one vision to move towards Green hydrogen / Renewables as the ultimate source of energy to reduce carbon foot print.

14 Hydrogen trains introduced in Germany with a plan to replace 3000 diesel locomotives with Hydrogen Train.

The technology adopted is something similar to a Fuel cell Car.
The trains mix hydrogen on board with oxygen present in the ambient air, with a fuel cell installed in the roof. This produces the electricity needed to pull the train.
