Reindustrialisation - A Generational Project


Loss of manufacturing in a country is not only shutting down of factories. Its repercussions are far deeper and wider. Factories are run over by nature, machines and assembly lines jam up, corrode, rust and crumble and can never be revived. Industrial towns are abandoned; one only has to look at the fate that befell once celebrated industrial cities of USA – Detroit, St. Louis, Pittsburgh, Cleveland and many more, where populations have declined to half or a third of their peak. People move out to seek other avenues of earning. Shops and restaurants, schools and colleges, town halls and parks, hospitals and offices, car dealerships and cab companies, all shut down. The loss of jobs is several times larger than just those of shop floor workers. All this is only because some unknown city across the ocean can sell cars and steel, televisions and toys a few percent cheaper.

What is worse is that the very backbone of the affected industry is broken. Skilled workers, who could make the finest cars and implements, toys and gadgets scatter, never to come back together under one roof to recreate the magic. The entire supply-chains, which typically come from the Medium and Small Industries (MSMEs), dry up since the bulk buyer has downed its shutters. MSMEs are the major job creators in any country and economy. Shutting down of these smaller units is devastating though not as spectacular as that of a car company. The latter’s loss of business is a subject of headlines and debates but not of the feeder small industries even though the impact on jobs and livelihood of workers of these MSMEs is far bigger. Entire capital is wiped out and bankruptcies are more common among MSMEs. Their employees often have lower levels of social security and entire families are driven to penury.

What Happens When a Car Factory Shuts Down?

Let’s take the example of a large car factory with US$10 billion in sales and the cascade of job losses and misery that follows when it shuts down. Such a car plant would typically be manufacturing 5,00,000 cars per annum.

The factory sources its parts and sub-assemblies as follows (only material cost taken here):

    In-house production:              10-15%

    Tier 1 (large) Suppliers:          50-60%

    Tier 2&3 (MSME) Suppliers:  25-30%      

When the factory shuts down:

  • Main Plant: 7500 direct employees of the company are laid off
  • Tier 1: 30,000 workers are laid off (These suppliers typically employ 3-5 workers per every worker in the main plant). Tier 1 companies typically manufacture engines, transmissions, brake systems, and electronics.
  • Tier 2: 75,000 workers lose their jobs. (Tier 2 suppliers typically employ 2-3 workers for every one worker in Tier 1). They manufacture sub-components such as wiring, seats, rubber-parts, and smaller assemblies.
  • Tier 3: 1,12,500 employees are rendered jobless. (Tier 3 suppliers typically employ 1-1.5 workers for every one worker in Tier 2). They typically produce basic components, such as metals, plastics, rubber and small parts.
  • Indirect Job Losses: 5,60,000 work hands lose their livelihood. As a multiplier effect for every manufacturing job lost 2-3 additional jobs are lost. They are typically in activities such as logistics, sales, dealerships, maintenance, catering, janitorial, services, security, transportation, schools, city-workers and all other local businesses that rely on factories and factory workers as customers.

Let’s summarise these job losses:

    Total manufacturing jobs:   2,25,000

    Indirect jobs:                        5,60,000

    Total Estimated Layoffs:     7,85,000

A disclaimer: Not all job-losses will be in the same country, state, or neighborhood. The ripples of a major factory shutting down will be felt across the world given the way supply-chains are established. One should look at ghost cities of China as a result of supply-chain dislocation let alone major factories closing down.    

Knee Jerk Reaction

Loss of factories, large and small, their equipment, skilled manpower, market-lines of their products, the service and after-sales business, all happen slowly, over years, decades or sometimes over the span of an entire generation.

Governments, policymakers, captains of industry and occasionally the affected population suddenly wake up one day and begin to talk in fuzzy terms like reshoring, onshoring, tariffs, China+1 etc. Little do they realise that in a deindustrialised country, bringing back factories must take the same long route in reverse. You can’t simply bring back blast furnaces and rolling mills to Pittsburgh, or cotton mills to Mumbai. Re-industrialisation is a generational project, not to be achieved in a few years of a government’s rule span. Remember these industrial centres were built by the blood and sweat of generations of entrepreneurs and workers.

What Needs to be Done?

Some of the unavoidable and quick action plans may include:

  • Policy changes that facilitate easy creation of industrial units, large and small
  • Easing of regulatory control
  • Easy access to banking and capital
  • Infrastructure Development – Highways, ports, power plants and power grids
  • Easy availability of land and permits
  • Low energy cost
  • Healthcare and social security
  • Education – Engineering and Research Oriented. Universities to take a relook at their programmes.
  • Training – Entrepreneurship, Vocational and business practices
  • Above all, nurture a culture of innovation.

Unless these and many more necessary steps are taken by the governments of those countries that have seen deindustrialization no significant job and wealth creation is possible slogans and statements of intent notwithstanding.

Even after that it will be a long haul.

Addendum:

Americans (USA) bought 16 million cars, SUVs and light trucks in 2024. Out of this 8 million were imports. Even in the cars made in USA only 40-50% was local content. Hence, local content in US car market is only 25%.

The US’ share in global R&D in automotive sector is a mere 18%.

Rolling Stock Exports – Indian Business that Needs to Grow

 


Figure: Export of Passenger Rail Vehicles from ICF, Perambur, Chennai

Hon’ble Railway Minister’s statement in the Parliament on the 17th of March may come as a surprise to many that India is emerging as an exporter of Rolling Stock. The Production Units of Indian Railways have been active players in the competitive world market of Rolling Stock, i.e. Passenger Coaches, Diesel Locomotives and Diesel Electric Multiple Units (DEMUs). This is not a new or recent phenomenon. IR has been exporting rolling stock for over five decades. A summary is given hereunder:

Diesel Locomotives

The Diesel Locomotive Works (DLW), now BLW, regularly exports locomotives to other countries such as Nepal, Mali, Senegal, Tanzania, Angola, Mozambique, and Vietnam, and Sri Lanka. The first diesel locomotive was exported to Tanzania as early as in the year 1976. IR has also exported remanufactured locomotives to many countries in addition to new stock. The DLW has also been a supplier of choice for non-railway diesel loco users, such as ports, power-plants, steel plants, and coal companies. Over 175 locomotives have been exported and nearly 650 to non-railway users in India. DLW/BLW has also supplied DG Sets for critical power backup to the Nuclear Power Corporation.

Passenger Coach Exports

Likewise, the Integral Coach Factory also exports railway coaches to other countries. and the factory has since exported 875 bogies and coaches to over 13 Afro-Asian countries, Angola, Bangladesh, Mozambique, Myanmar, Nepal, Nigeria, Philippines, Sri Lanka, , Taiwan, Tanzania, Uganda, Vietnam, and Zambia. The first export was of 47 coaches to Thailand as early as in1967. ICF has also supplied special coaches for movement of troops to the Army and other classified purposes. Of late the newer units, viz. RCF and MCF have also found ready international buyers for their produce.

As can be seen, Indian Railway’s Production Units have been exporting rolling stock since 1967. They are also maintained and serviced by Indian Railway personnel till the local engineers and artisans become adept at it.

Private Sector Export

Private Sector has been a recent entrant in the export of India-made rolling stock in the world market primarily in the Metro Rail Sector. Bombardier-ALSTOM have been exporting for many years. Titagarh is a new player. That they have exported to discerning European and Australian markets is particularly commendable. Indian Railways, as a Ministry, has had no role in their ventures. Their success has come after years and decades of patience, high-quality design and world class manufacturing setups.

Recent efforts by the Marhowra Diesel Loco Factory towards export of India-made diesel locomotives is another success story of the Indian private sector. The Marhowra factory was setup by GE, now Wabtec, with a minority share of Indian Railways and the contract had enabled GE to export after meeting local needs.

What Gives Confidence to Foreign Buyers?

Trains and Locomotives have long working life – twenty to thirty years. This is far longer than the lifespan of an automobile or a consumer durable. Besides, trains are pubic transport and safety is of paramount importance. It is therefore expected that the buyer looks for a reliable, safe, easy-to-maintain, and low lifecycle cost designs. Demonstration of these attributes is often achieved by long term use of the rolling stock in the home country that manufactures them or some relatable variant of the design on offer. This is also the case in rolling stock exports from India. Whether it is locomotives, mainline passenger coaches, DEMUs, or metro coaches, the strength to export them from India was built up after years and decades of local use. A robust supply-chain to help maintain these stocks long-term is also an essential factor.

Are the Indian Industry and the Government Doing Enough?

The current level of exports from India doesn’t even scratch the surface of the worldwide railway business of US$51 billion. A lot needs to be done by way of government policy and private enterprise to capture a significant slice of the pie.

1.    Special Economic Zones – Railway vehicles, by the nature of their size and manufacturing process, require large areas to setup factories. Tax relief on import and manufacture of subassemblies, design and exports to be offered.

2.   Import of technology and R&D Centres for indigenous technology development to be encouraged.

3.     A workable industry-academia interface needs to be developed.

4.  Indian Railways’ own Production Units need to be synergised into a conglomerate on the lines of the CRRC of China, which has over forty companies under one umbrella.

5.   Diesel Loco technology in India, which is heading towards oblivion, must be revived. There is a vast market for Indian diesel locos waiting to be tapped what with our ultra low prices. The potential spin-off gains to the industry at large is huge.

6.    A Test Track for extensive testing and design prove out – Test tracks can test rail vehicles of various gauges, applications at different speeds and track conditions. Fortunately, the long overdue Indian test track is being built in Rajasthan and is nearing completion. This should be opened to private builders of rolling stock in much the same way Army’s armament test ranges have been opened to private players.

Conclusion

It is essential that we recognise the good work that has been done by Indian Railways’ manufacturing units and encourage them to develop new designs and build. This is a highly competitive business, and these units need to be free from the fear of Railway Vigilance and enquiries by authorities, who don’t understand complex manufacturing. There is also a need to empower the management of these units to at least the levels of those of Maha Ratna PSUs. This is easily within sight and can be done tomorrow.

Of High Perch and the Hard Ground

 

Picture Courtesy: freepik.com

It is necessary to know your men (and women) if you want to deliver magic and go beyond the incremental. The difference between a leader and a manager is stark even though books have been written to explain it as if it was a fine and indistinguishable gap.

A manger sits on a high perch and expects the men to deliver on the ground. So, they do deliver, but just the way they have been doing and maybe a bit better. A leader is out there with his team roughing it out on the ground and makes them climb heights neither they nor he himself ever thought was possible. For a leader the sum is always more than the parts; in fact, it is not a sum, but a new number altogether. A leader doesn’t do two plus two to make four; he makes them march together and makes a twenty-two. Being out there in the field doesn’t necessarily mean working on that nut and bolt. It means being able to wield the spanner and show them how it is done if the occasion arises, and in good faith.

As one grows in the organisation the size of the team assigned to him grows and a time comes, when knowing all your men becomes impossible. While it is true that the team directly reporting to a senior manager (I prefer the term leader) is still small and it is possible to know them intimately, the satisfaction of knowing all the men out there diminishes. What does a people’s man, the leader, do under such circumstances?

What does a leader do, when there are a thousand men working in the organisation or ten thousand? This is a question that have been frustrating me for years. Even as one wishes one could put one’s hand on the fellow worker’s shoulder and ask about his welfare, health and family, it is not possible as a regular behaviour. You simply can’t know all of them personally.

But the reverse is still possible. Nothing prevents your people from knowing you intimately. It is the next best thing if your men look at you and see in you “their man”. If you walk among them, each one of them should bond with you even if you can’t do the same, to the same degree, in return. The biggest proof of being owned by your men is that one of them, anyone of them, can walk up to you without fear and hesitation, look into your eyes, and speak with you. Believe me, the feeling is electrifying. 

If your men break into a smile upon seeing you, if they think they can come to you with a problem and go back with a solution, if they meet you with sadness and go back with hope and reassurance, they will deliver magic for you.

This is not to say that a leader should shirk from taking tough decisions or being unpleasant when the occasion demands. But when one does that, people understand.

(Please pardon my use of the word “men” repeatedly. There is no gender bias, just the need to let the language flow easily)

Hydrogen as Fuel: A Technical Critique


Image Courtesy: greatgameindia.com
 

Hydrogen is often touted as a “fuel of the future,” but a technical examination reveals that it functions primarily as an energy carrier rather than a primary fuel. Recent introduction of hydrogen-powered trains by the Indian Railways has brought the discussion on hydrogen to public mind-space in India and must trigger a reasoned debate.

By definition, a fuel provides more energy than is required for its extraction or production. Examples include fossil fuels (coal, petroleum, natural gas) and nuclear fuels (enriched uranium or plutonium). Hydrogen, however, requires substantial energy input for production, storage, and distribution, making it analogous to a battery in its role as an energy storage medium, only less efficiently.

Thermodynamic Analysis

1.  Electrolysis Efficiency:

State-of-the-art electrolysers operate at a maximum efficiency of approximately 65%, constrained by thermodynamic limits. For every unit of energy input, only 65% is converted into usable hydrogen energy. This process will not see dramatic improvements due to the inherent energy losses governed by the second law of thermodynamics.

2.  Fuel Cell Efficiency:

Hydrogen is typically used in fuel cells to convert chemical energy back into electricity. The most advanced proton exchange membrane (PEM) fuel cells achieve an efficiency of around 65%, with a theoretical maximum close to 70%.

3.  Roundtrip Efficiency:

Combining electrolysis and fuel-cell efficiencies, the roundtrip efficiency of hydrogen energy systems is further adversely affected by:

Additional energy losses occur in hydrogen compression (to 800 bar), liquefaction (-253°C), and transportation, which consume another 7–10% of the energy. This reduces the effective efficiency to approximately 35%, or lower.

4.  Comparison with Batteries:

In contrast, lithium-ion batteries have a charging efficiency of about 90% and a discharging efficiency of roughly the same. The practical roundtrip efficiency for batteries is 80+%.

Batteries thus offer more than twice the efficiency of hydrogen systems for energy storage and retrieval.

Hydrogen in Internal Combustion Engines (ICEs)

When used in ICEs, hydrogen’s efficiency drops dramatically. ICEs have a peak thermodynamic efficiency of around 35%. Combining this with electrolysis efficiency of 65%, and after accounting for compression, storage, and transportation losses, the effective efficiency falls to a mere 16%. This makes hydrogen a poor choice for ICE applications.

Infrastructure Challenges

1.  Storage and Transportation:

Hydrogen has a very low volumetric energy density, requiring compression to 800 bar or liquefaction at -253°C. Both processes are energy-intensive, with compression consuming 10–15% of the energy content and liquefaction consuming up to 30%. Hydrogen is also prone to leakage due to its small molecular size, which causes embrittlement in storage and transport materials, a serious technical challenge.

2.  Electrolyser and Fuel Cell Costs:

The capital costs of electrolyser systems and fuel cells remain high, with significant maintenance and replacement costs over time. Furthermore, large-scale hydrogen storage infrastructure (pipelines, cryogenic tanks) is underdeveloped, requiring significant investment.

3.  Energy Source Dependency:

Hydrogen’s environmental benefits depend heavily on the energy source used for electrolysis.

      Green Hydrogen: Produced from renewable electricity, it is sustainable but expensive. Even considering that renewal energy is available in plenty and in surplus amounts, use of battery to store and deliver that energy beats the hydrogen cycle again.

     Grey/Blue Hydrogen: Derived from methane or coal, it undermines the environmental benefits due to CO emissions and methane leakage.

 Potential Niche Applications

While hydrogen struggles as a general-purpose energy carrier, it holds promise in specific high-value applications, such as:

1.  Industrial Feedstock:

   Green Steelmaking: Hydrogen can replace coke as a reducing agent in iron ore processing. Since hydrogen is consumed chemically, only the electrolysis efficiency (65–70%) matters. Tata Steel and other major players are investing heavily in green steel production. Besides, high pressure or cryogenic storage may be dispensed with.

  Ammonia Production: Hydrogen is essential for synthesizing ammonia, a critical component of fertilizers.

2.  Hard-to-Decarbonize Sectors:

 Hydrogen may possibly be viable for:

    Long-haul aviation, where batteries are impractical due to weight constraints though hydrogen tanks pose a challenge here too.

       Maritime shipping, using hydrogen-derived fuels like ammonia or methanol.

      Seasonal energy storage for grid balancing in regions with high renewable penetration.

 Hydrogen vs. Batteries: The Practical Reality

Hydrogen systems currently lag behind batteries in terms of efficiency, cost, and infrastructure readiness. Batteries dominate in applications where high roundtrip efficiency and scalability are crucial, such as electric vehicles and grid-scale energy storage.

The enthusiasm for hydrogen often appears to be driven by economic interests rather than scientific principles. Equipment manufacturers and infrastructure developers stand to benefit from hydrogen’s adoption, regardless of its inefficiency. This recalls the gold rush era, where the blacksmiths profited more than the miners themselves.

Policy Recommendations

Policymakers must approach hydrogen with a nuanced understanding:

  • Prioritize hydrogen development for niche applications where it offers unique advantages (e.g., green steelmaking, aviation).
  • Avoid over-subsidizing hydrogen for areas where batteries or other technologies are more efficient.
  • Invest in renewable energy expansion to ensure hydrogen production (via electrolysis) is sustainable.
  • Support research into reducing the costs of electrolysers, fuel cells, and hydrogen storage systems.

Conclusion

Hydrogen’s role in the energy transition should be realistic and targeted. While it has potential in industrial processes and hard-to-decarbonize sectors, its inefficiency and infrastructure challenges preclude it from becoming a universal energy solution. Discussions around hydrogen must be grounded in thermodynamic principles, economic feasibility, and practical considerations, rather than being swayed by hype or vested interests.

By focusing on where hydrogen truly adds value, we can avoid misallocating resources and accelerate the transition to a sustainable energy future. If the launch of hydrogen-trains by Indian Railways leads to intelligent and techno-commercial debate in the country, such a venture would have served a far bigger purpose than simply being a technology demonstrator or people-carrier.
