Introduction (Context)

Indian Railways has recently tested its first hydrogen-powered coach, marking a significant step towards the deployment of Hydrogen Fuel Cell (HFC) technology in India’s vast railway network. 

Hydrogen-powered trains, or hydrail, are emerging as a promising zero-emission alternative to diesel-electric locomotives. 

What are Hydrogen Trains?

• Hydrogen trains are electric trains with an onboard power source, unlike conventional electric trains that are powered via overhead wires. 
• They use HFC (Hydrogen Fuel Cell) technology, which generates energy through the electrochemical reaction of compressed hydrogen with atmospheric oxygen, emitting water vapour as the sole byproduct making it a zero-emission mechanism. 
• The electricity produced by the fuel cell is stored in batteries, which provide additional power during acceleration and climbing inclines. 
• Hydrogen trains also employ regenerative braking technology, which captures the kinetic energy (motion energy) generated during braking and converts it into electricity to recharge onboard batteries. 

Hydrogen Fuel Cell vs Electric Trains

• Hydrogen trains work by first using electricity to produce hydrogen (through electrolysis), and then converting that hydrogen back into electricity inside the train to run it. Because of this double conversion process, some energy is lost along the way.
• Electric trains, on the other hand, draw electricity directly from overhead wires. This makes them more energy-efficient, especially when the power comes from renewable sources like solar or wind.
• This means that, over their full life cycle, electric trains are generally more efficient than hydrogen trains.

Green Hydrogen vs Grey Hydrogen

• Green Hydrogen: Made using renewable energy (like solar or wind) to split water into hydrogen and oxygen. This process does not release harmful gases, so the trains powered by it can truly be called zero-emission.
• Grey Hydrogen: Produced from fossil fuels (like coal or natural gas). This process releases carbon dioxide (CO₂), which reduces the environmental benefits of hydrogen trains.
• For hydrogen trains to actually fight climate change, India needs to shift from grey hydrogen to green hydrogen at a large scale. Only then can hydrail become a genuinely clean and climate-friendly option.

Advantages of Hydrail

• Eliminates smoke emissions from fuel combustion, reducing noise and air pollution.
• Operates on both electrified and non-electrified routes, ensuring greater flexibility.
• Particularly useful for routes where overhead electrification is unfeasible or prone to disruption.
• Can be refuelled in 20–25 minutes, faster than battery-electric train recharging.
• Supports India’s net-zero target by 2070; Indian Railways already reduced fuel use by 136 crore litres (2018–19 to 2023–24).
• Though initial investments are high, cost-effective on non-electrified routes by avoiding overhead electrification costs.
• Reduces dependence on imported diesel, strengthening energy security and improving balance of payments.

Challenges

• Hydrail has a substantially high initial cost of production compared to both electric and diesel trains. 
• It requires the development of an extensive system for hydrogen production, storage and distribution – an infrastructure that is largely absent in India today.
• The massive refueling stations and machinery needed to support the substantial fleet of hydrogen trains present another logistical and financial challenge. 
• The highly flammable nature of hydrogen requires adherence to strict safety standards from production to storage and refuelling, necessitating further investment in safety infrastructure and training for railway personnel. 
• Currently, most hydrogen in India is derived from fossil fuels → undermines decarbonisation goals.

Way forward

• Leverage India’s growing renewable energy capacity to scale up green hydrogen production and reduce costs.
• Develop a decentralised hydrogen infrastructure focusing on storage and refuelling, inspired by the Hydrogen Highways model under NGHM.
• Invest heavily in research and development to improve hydrogen fuel cell efficiency, safety standards, and cost competitiveness.
• Ensure long-term policy support with clear roadmaps, incentives, and public–private partnerships to sustain momentum.
• Strategically deploy hydrogen trains on non-electrified, remote, and hilly routes where they have maximum advantage.

Conclusion

Hydrogen trains mark a significant milestone in India’s pursuit of a sustainable and decarbonised transport system. With the right mix of renewable energy integration, infrastructure development, and supportive policies, India can position itself as a global leader in green hydrogen innovation.

Introduction (Context)

The judiciary is often seen as the guardian of constitutional morality, demanding accountability and transparency from the legislature and executive. However, recent revelations about Justice B.V. Nagarathna’s dissent in the Collegium’s recommendation to elevate Justice Vipul M. Pancholi highlight the opaque nature of judicial appointments. This raises serious concerns about transparency, accountability, and democratic legitimacy within the judiciary itself.

Constitutional Provisions Related to the Appointment of Judges

1. Article 124(2) – Supreme Court Judges

• Judges are appointed by the President through a warrant.
• Appointment requires consultation with Chief Justice of India (mandatory for all judges except CJI) and other SC and High Court judges (discretionary for the President)

1. Article 217(1) – High Court Judges

• Judges appointed by the President after consultation with: Chief Justice of India, Governor of the State and Chief Justice of the High Court (mandatory for all except Chief Justice)
• Tenure: up to 62 years (except additional/acting judges under Article 224).
• Here, consultation is mandatory, unlike Article 124(2) which allows some discretion.

About Collegium system

• The Collegium System is the way judges of the Supreme Court and High Courts are appointed in India.
• It is not written in the Constitution or in any law. Instead, it was created by the Supreme Court itself through judgments.
• In this system, a group (called the Collegium) of the 5 senior-most judges of the Supreme Court, including the Chief Justice of India (CJI), decide:

• Who will be appointed as a judge in the SC and High Courts.
• Who will be promoted (from High Court to SC).
• Transfers of judges from one High Court to another.

It aims to keep the judiciary independent from political influence.

Key Supreme Court Judgments on Judicial Appointments

• First Judges Case (S.P. Gupta v. Union of India, 1981) – Introduced the idea of consultation between the President and CJI for appointments, but gave more power to the executive.
• Second Judges Case (Supreme Court Advocates-on-Record Association v. Union of India, 1993) – Held that the Chief Justice of India and senior judges have primacy in appointments, reducing executive control.
• Third Judges Case (1998) – Clarified the Collegium system, giving a five-member panel of senior SC judges, headed by the CJI, the authority to select and recommend judges for the Supreme Court and High Courts.

Issues with the collegium system

• The Collegium operates in closed-door meetings without publicly disclosing deliberations. Even dissent by senior judges (e.g., Justice B.V. Nagarathna’s objection) is hidden from the public.
• Judicial appointments are made by a self-selecting group of judges with no role for the legislature or public scrutiny. This creates a “judges appointing judges” model, which lacks democratic accountability.
• Collegium decisions are rarely explained; reasoning behind appointments, rejections, or transfers remains unknown.
• As there is no transparency, appointment on the basis of preferences are also patronized, over deserving candidates and qualifications.
• Separation of judiciary is the keystone of Indian democracy, and this idea has been emphasized by the constitution makers by including the Article 50 (directive principles of state policy) mentioning that the State shall take steps to separate the judiciary from the executive in the public services of the State. But the opaque collegium system is used by the politicians to fulfill their self-interest.

For a short period in 2018, the Court uploaded fuller reasons for the Collegium’s choices and rejections. However, the experiment was short lived, with the explanation that disclosure might damage reputations.

Importance of transparency in appointments

• • Transparency in judicial appointments helps build trust and legitimacy in the system.

• Countries like Britain and South Africa show that making criteria and assessments public improves accountability.

• Judges make decisions on civil liberties, executive power, and federal authority, so citizens have a right to know why judges are appointed.
• Publicly sharing reasoning ensures the judiciary follows the same accountability it expects from other branches of government.
• Even though judges are unelected, they are entrusted with protecting rights against majoritarian excesses and maintaining constitutional balance. Transparency does not weaken their independence; instead, it reinforces trust and strengthens democracy.

Way Forward

• The Collegium must embrace reform to ensure judicial appointments are transparent and accountable.
• The process should meet the highest standards of justification, moving away from a culture of secrecy.
• Opportunities for change should be actively implemented and sustained, rather than rolled back, to strengthen transparency and integrity.
• Structured reforms could include public disclosure of dissenting opinions, clear reasoning for appointments, and mechanisms to maintain independence while enhancing openness.

Conclusion

A judiciary that follows the same standards of openness and accountability it expects from other branches will not lose autonomy. On the contrary, transparency will strengthen public trust, reinforce legitimacy, and anchor the judiciary’s independence firmly in democratic values.

Reforming the Collegium is essential to preserve both judicial authority and the credibility of India’s democracy.
