India wants to be the world’s green hydrogen factory. In January 2023, the government approved the National Green Hydrogen Mission, targeting the production of 5 million metric tonnes (MMT) of green hydrogen per year by 2030. This is expected to attract ₹8 lakh crore of investment and create around 6 lakh jobs. This is a huge bet on a fuel that didn’t even exist as a major product a few years ago.
The problem with green hydrogen is that these projects are expensive and slow to make profits, and on top of that, there is a lot of uncertainty with the technology at scale. Traditional banks will not view these projects as sound investments. This is why green bonds have become important to fund these projects. The government issues sovereign green bonds to help fund its portion of the mission. Corporate entities can issue green bonds as well.
The markets for green bonds are quickly growing to help fund the Mission’s need for electrolyzers, renewable energy capacity, and hydrogen infrastructure. But how much of this financing is actually flowing toward hydrogen specifically, and how reliable is it? This article walks through the numbers, the mechanics, and the gaps, so you get a realistic picture, not just the headline ambition.

What Is the National Green Hydrogen Mission, in Financial Terms
The Mission has an initial allocation of ₹19,744 crore [1]. The major component, ₹17,490 crore, is under the SIGHT (Strategic Interventions for Green Hydrogen Transition) programme. Here, ₹4,440 crore will be used to implement incentives for the manufacturing of domestic electrolysers, and ₹13,050 crore will provide incentives for the production of green hydrogen. The remaining funds will be directed towards funding pilot projects, research and development, and the creation of hydrogen hubs.
While government funding is an important part of this initiative, the Mission envisions that more than ₹8 lakh crore of required capital will be funded by the private sector and capital markets. The government’s goal is to use its funding to reduce the risk associated with the sector and attract private capital, including funding from the bond markets, to do the majority of the heavy lifting.
There has been a gap between the targets set and progress made on the ground. By early 2026, around 8,000 tonnes per annum of green hydrogen production capacity [2] had been commissioned, compared with the National Green Hydrogen Mission’s target of 5 million tonnes of annual production capacity by 2030. That gap between ambition and execution is precisely why the financing conversation matters: without deeper, cheaper capital pools, the Mission’s 2030 targets look increasingly stretched.

How Sovereign Green Bonds Fit Into the Picture
On January 25, 2023, the Reserve Bank of India (RBI) auctioned ₹8,000 crore [3] of sovereign green bonds, marking India’s entry into the sovereign green bond market. Since the first issuance, the government has raised ₹72,697 crore through sovereign green bonds till FY2025–26, with ₹15,000 crore [4] of issuance planned for the first half of FY2026–27, as part of its ₹8.20 lakh crore H1 borrowing programme.
The proceeds of green bonds are directed towards a fund for ‘green’ expenditures like renewable energy, means of clean transportation, energy efficiency, and sustainable management of resources. Green hydrogen falls under renewable energy expenditures, as well as funding for electric locomotives and other expenditures for metro rail projects.
A few things are worth knowing if you’re evaluating this as a financing channel:
- Sovereign green bonds don’t fund specific projects directly. Green bond proceeds are pooled and later matched to funds allocated by the government for green spending, so you can’t point to a specific hydrogen plant and say “this bond paid for it.”
- The “greenium,” an expected pricing premium on green bonds, has been volatile. Early on, investors were expected to accept slightly lower yields (a pricing premium called a greenium) in exchange for the ESG label. However, since 2024, the RBI has reduced the size of, and even cancelled, several planned sovereign green bond auctions, indicating that investors have come to expect green bonds to be issued at the same yield as regular government securities, or higher.
- Renewable energy, including the Green Hydrogen Mission, gets only a small allocation. Based on previous budgets, nearly 50% of the proceeds from sovereign green bonds have been allocated to fund energy-efficient electric locomotives for the Indian Railways, rather than hydrogen-related infrastructure.

Corporate Green Bonds: A More Direct Route to Hydrogen Financing
Sovereign bonds allow a government to fund its spending, but corporate green bonds can fund specific renewable energy and hydrogen-related projects. Companies and financial institutions in India are using this opportunity to fund the manufacturing of electrolysers, renewable energy capacity that feeds hydrogen production, and similar infrastructure.
Imagine a company that manufactures electrolysers or produces renewable-energy-supported hydrogen wants to raise debt specifically to support a green project. A green bond allows them to do that, unlike a traditional corporate bond, along with independent checks to ensure the proceeds are used for the intended purpose. This reason, among others, draws large global investors, like sovereign wealth funds and ESG-mandated funds, to corporate green bonds over sovereign bonds for hydrogen exposure.
SEBI’s 2017 green bond guidelines, since aligned with the ICMA Green Bond Principles, require disclosure of the use of proceeds and the engagement of a third-party verifier, forming the basis of most corporate green bond listings in India today.
Challenges Facing India’s Green Bond Market for Hydrogen Financing
A few structural issues keep coming up in how India’s green bond market interacts with green hydrogen specifically:
- Tenor mismatch: Hydrogen-based projects need long-term capital (15-25 years), which matches the offtake agreements, in contrast to the short-maturity bonds the green bond market in India mostly offers.
- Weak secondary market liquidity: Green bonds are usually held till maturity. This discourages price discovery and new investors from entering.
- Greenium erosion: The Absence of a consistent price benefit for “green” labeling erodes the incentive for market participants to issue green bonds as opposed to conventional debt. This defeats the original pitch that green bonds would be priced cheaper than regular debt.
- Sector-specific tracking gap: There is no clear reporting line on how much money from sovereign green bonds has been dedicated to hydrogen compared to other renewables; it’s often bundled under “renewable energy,” which also includes the National Green Hydrogen Mission allocation.
To provide some perspective, certain studies show that India’s overall green financing may reach $170 billion by 2030. Compared to the current annual green bond issuance, this number shows just how large the green bond financing gap is and how much more work must be done through banks, green banks, blended finance, and multilateral funding and not through bonds alone.
What This Means for Investors and Market Watchers
The key implication is that while sovereign green bonds are more of a signaling mechanism and reference point than a dedicated hydrogen funding vehicle, corporate green bonds, especially when issued by renewable energy developers, electrolyzer manufacturers, and industrial firms with hydrogen offtake commitments, offer more direct, traceable exposure. Retail investors interested in participating can access sovereign green bonds via the RBI’s Retail Direct platform or stock exchanges, while corporate green bonds are typically accessed through bond platforms or institutional channels.
National Green Hydrogen Mission Frequently Asked Questions
The National Green Hydrogen Mission aims to make India a global hub for the production, use, and export of green hydrogen and its derivatives while reducing fossil fuel dependence and supporting decarbonization.
A green bond is a debt instrument whose proceeds are earmarked for eligible projects or assets that deliver environmental benefits. In India, green debt securities can finance areas including renewable energy and clean technologies.
It’s the yield discount investors accept for a bond labeled “green” in exchange for its ESG credentials. In India, this premium has been inconsistent, sometimes disappearing entirely, which has affected sovereign green bond demand.
Not directly. Proceeds are pooled and allocated against a broader basket of government green spending, of which renewable energy (including the Green Hydrogen Mission) is one category.
