After understanding the power of hydrogen the scientist have started deep research on hydrogen and its utilization for different purpose. Green hydrogen is one of the revolutionizing renewal energy storage comes with multiple benefits.
It is an energy storage that offer to store access energy from different renewable energy sources like solar, wind and grid stability.
In this post you will find the benefits of green hydrogen, and how it help to store renewable energy source and how government from different country encouraging different companies to for the RND of green hydrogen.
In a country like India, blessed with abundant renewable resources and vast industrial capacities, green hydrogen offers a unique chance to lead the clean energy movement. Imagine an energy system that not only fuels growth but also safeguards our environment this vision is becoming reality thanks to green hydrogen.
Photocatalytic materials, photoelectrocatalytic materials, and photoelectrocatalytic panels play a key role in producing green hydrogen. These technologies tap into renewable energy especially sunlight to generate hydrogen in an eco-friendly way.
State-of-the-Art Green Hydrogen Technologies
Green hydrogen is produced by splitting water into hydrogen and oxygen using electricity from renewable sources. In recent years, this field has seen rapid improvements boosting efficiency, cutting costs, and making systems more durable. These advances have cemented green hydrogen’s place as a leading option for clean energy generation.
- Alkaline Water Electrolysis: This is the most established method for producing green hydrogen and has been used commercially for decades. Although reliable, alkaline electrolysis tends to be less energy-efficient compared to newer techniques.
- Proton Exchange Membrane (PEM) Electrolysis: PEM systems have gained popularity for their high efficiency and compact design. They do come with higher upfront costs, but their performance advantages often justify the investment, especially in areas where space is limited or rapid response times are needed.
- Solid Oxide Electrolysis (SOE): SOE technology is still maturing but shows promise for achieving top-level efficiency and lower long-term costs. Operating at high temperatures makes these systems more complex and initially more expensive, but they could become the most cost-effective option as the technology advances.
Advances in Photoelectrocatalysts
Research into photoelectrocatalysts for hydrogen production began in the early 2000s and has grown steadily ever since. Early experiments used materials like titanium dioxide (TiO₂), various semiconductors, and nanomaterials. While these initial designs demonstrated the concept, efficiency and stability remained limited.
Scientists responded by exploring new materials and refining existing ones. Metal chalcogenides, perovskite materials, and composite structures were investigated to improve how these systems absorb light, separate charges, and catalyze reactions.
A breakthrough came with tandem photoelectrochemical cells, which stack multiple light-absorbing layers to capture a broader range of the solar spectrum dramatically increasing overall energy conversion rates compared to single-layer designs.
Benefits of Green Hydrogen
Economic Benefits: Powering National Prosperity
Green hydrogen offers a path to energy independence. By tapping into domestic renewable resources, countries can cut down on costly fuel imports. India’s National Green Hydrogen Mission aims to produce 5 million metric tonnes of green hydrogen every year by 2030.
This initiative could save around ₹1 trillion (about $12 billion) in fossil fuel imports annually. Beyond savings, it is expected to create thousands of new jobs, attract significant investments, and reduce reliance on foreign energy sources.
Energy Storage and Grid Stability
One of green hydrogen’s most important roles is storing excess renewable energy. When wind and solar systems generate more power than needed, that surplus electricity can split water, creating hydrogen.
This stored hydrogen can later be converted back to electricity or used directly, ensuring the grid remains stable even when the sun isn’t shining or the wind isn’t blowing. By bridging the gap between energy supply and demand, green hydrogen maximizes the use of renewable resources and strengthens energy reliability.
Localized Energy Ecosystems
Imagine “hydrogen valleys” self-contained regions where renewable energy is produced, stored, and used locally. These hydrogen hubs could transform both city and countryside, connecting homes, industries, and transport with clean, reliable power.
By integrating production and consumption in one area, these ecosystems reduce transmission losses, support local economies, and pave the way for a truly decentralized energy future.
Green Hydrogen as Fuel
Fuel cell technology has unlocked new possibilities for clean transportation. In fuel cell electric vehicles (FCEVs), hydrogen stored in a tank reacts in a fuel cell to produce electricity that powers the motor. FCEVs emit only water vapor, making them a zero-emission alternative to conventional vehicles.
Although FCEVs currently account for just 0.5% of new low-emission vehicle sales, the market is growing.
Hyundai plans to produce 500,000 hydrogen vehicles by 2030. Paris is building a fleet of hydrogen-powered taxis, and in many European cities, waste collection trucks run on hydrogen. This trend shows the clear advantage of green hydrogen in reducing transportation emissions.
Green Hydrogen vs. Other Types of Hydrogen
- Grey Hydrogen: Produced from natural gas or coal, grey hydrogen generates large amounts of CO₂ emissions. It still makes up about 95% of global hydrogen production.
- Blue Hydrogen: Similar to grey hydrogen, but includes carbon capture and storage (CCS) to trap CO₂ before it reaches the atmosphere. While it reduces emissions compared to grey hydrogen, it doesn’t eliminate them entirely.
- Green Hydrogen: Generated by electrolyzing water using electricity from renewable sources no CO₂ emissions are involved. This is the cleanest form of hydrogen production.
The Future of Hydrogen in India
India’s Renewable Energy Capacity
India is already a global leader in renewables, aiming for half of its energy to come from non-fossil fuel sources by 2030. This strong renewable base makes the country an ideal place to scale up green hydrogen production.
Existing and Planned Production Facilities
India’s first green hydrogen plant in Bikaner, Rajasthan, runs entirely on solar power. Other states like Gujarat, Tamil Nadu, and Karnataka are fast becoming green hydrogen hotspots. Over 25 production plants are planned across the nation, signaling a robust future for this clean fuel.

Frequently Asked Questions
Due to its high capability of storing renewable energy sources like solar and wind, people have many doubts and raised several queries on the Internet and below are some of the mostly asked question and their answer:-
What is the green hydrogen revolution?
The green hydrogen revolution refers to producing hydrogen using renewable electricity such as wind or solar power so that no CO₂ emissions are generated. This approach not only cuts greenhouse gases but also provides a flexible energy store and can be used across many sectors.
How safe is hydrogen storage?
Storing hydrogen brings a few risks: it ignites easily, high-pressure and very low-temperature conditions can be dangerous, and hydrogen molecules can seep through small gaps. Proper container design, safety protocols, and monitoring systems are essential to keep hydrogen storage secure.
What is PM Modi’s stance on green hydrogen?
Prime Minister Narendra Modi has set ambitious goals: achieving 500 GW of renewable energy capacity and producing 5 million tonnes of green hydrogen by 2030. He emphasizes how green hydrogen will strengthen India’s commitment to a sustainable energy future and enhance its role in global energy markets.
Is hydrogen hot or cold?
At normal temperature and pressure, hydrogen is a colorless, odorless gas. When cooled to −252.8°C (−423°F), it becomes a liquid. So, whether hydrogen is “hot” or “cold” depends on its physical state in storage or use.
