Researchers at Nanjing University have created a new way to make clean hydrogen directly from seawater using sunlight.

They built a special material (cobalt phosphide on carbon nitride) that can sit in seawater. When sunlight hits it, it splits water into hydrogen and oxygen—no electricity, no filters, and no extra equipment needed.

Even better, the natural salt in seawater actually improves performance by about 15%, so there’s no need to remove salt first.

The system ran successfully for 1,000 hours outdoors. Scientists estimate that a 1 km² setup could produce about 4,500 tonnes of green hydrogen per year.

In short: it’s a simpler, cheaper way to make clean fuel directly from the ocean using sunlight.

Green Revolution in India: Focus on Green Hydrogen

1. What is Green Hydrogen?

Green hydrogen is hydrogen fuel produced through the process of electrolysis, where water (H₂O) is split into hydrogen (H₂) and oxygen (O₂) using electricity generated from renewable energy sources such as wind, solar, or hydropower. This process ensures that the hydrogen produced is free from carbon emissions, making it a clean and sustainable energy carrier.

2. What is the Role of an Electrolyser?

An electrolyser is a crucial device in the production of green hydrogen. It uses electrical energy to drive the chemical reaction that splits water into hydrogen and oxygen. There are different types of electrolysers, including alkaline electrolysers, proton exchange membrane (PEM) electrolysers, and solid oxide electrolysers. Each type has specific advantages and is selected based on the application and scale of hydrogen production.

3. Why is India Moving Towards Green Hydrogen?

India is moving towards green hydrogen for several reasons:

a) Energy Security: Reducing dependency on imported fossil fuels and enhancing energy self-reliance.

b) Environmental Impact: Mitigating carbon emissions and addressing climate change commitments.

c) Economic Opportunities: Creating new industries and job opportunities in the green hydrogen sector.

d) Technological Leadership: Positioning India as a leader in renewable energy and clean technologies.

4. End User Applications for Green Hydrogen

Green hydrogen has diverse applications across various sectors:

a) Industrial Use: As a feedstock in refineries, ammonia production, and steel manufacturing.

b) Transportation: Fuel for hydrogen fuel cell vehicles, buses, trucks, and even trains.

c) Power Generation: As a backup power source and in fuel cells for stationary power generation.

d) Residential and Commercial Use: Heating and electricity supply through hydrogen fuel cells.

5. Indian Government Policy on Green Hydrogen

The Indian government has introduced several policies to promote the adoption of green hydrogen:

a) National Hydrogen Mission: Launched to encourage the production and utilization of hydrogen as a clean energy source.

b) Incentives and Subsidies: Financial support for research, development, and deployment of hydrogen technologies.

c) Regulatory Framework: Developing standards and safety protocols for hydrogen production, storage, and distribution.

d) Public-Private Partnerships: Encouraging collaborations between government bodies and private enterprises to accelerate the hydrogen economy.

6. How to Transport Green Hydrogen?

Transporting green hydrogen can be challenging due to its low density and high reactivity. Common methods include:

a) Compressed Hydrogen: Transported in high-pressure tanks.

b) Liquid Hydrogen: Cooled to cryogenic temperatures and transported in insulated tanks.

c) Ammonia: Converted to ammonia for easier transportation and later reconverted to hydrogen.

d) Hydrogen Pipelines: Dedicated pipelines for direct hydrogen transportation.

7. Why is Green Hydrogen Still Costly?

Green hydrogen remains costly due to several factors:

a) High Production Costs: Electrolysis is energy-intensive and expensive.

b) Infrastructure Costs: Developing hydrogen production, storage, and distribution infrastructure is capital-intensive.

c) Scale and Efficiency: Current technologies are not yet optimized for large-scale, cost-effective production.

d) Market Development: The market for green hydrogen is still nascent, leading to higher costs due to lower economies of scale.

8. Tenders Across Value Chain of Green Hydrogen in India shows potential for Companies working in this sector.

I am placing the following here as it is related to green hydrogen, but it is not about trains.

Absolutely. The train story was something that jumped out at me when I hadn't thought about this for a while.

Hydrogen tech is as old as the first internal combustion engine, but, there has never been any serious industrial research on it until now.

It's only a question of how do you get the power to electrolyze water. Most electricity is, of course, filthy. What if you just ran some electrodes from an exercise bike and made it yourself?

Could you pedal for a couple of hours and be able to drive your car all week?

I would say that everything here is among the best developments for humanity. No one has said it's free energy and the green-ness of it is a matter of degree, but I think it is the right thing to be taken seriously, and, of course, I am mainly going to see it in those places who are technology-licensing with China, although we could just as easily have built such a workshop right here instead of the junk they are cranking out.

For example, there is an uber-green colony where I used to live, and I went through their site to confirm for myself, yes, this is an improved way of making a modern human neighborhood. But two things. It's only for the well-to-do. And, it has its own second-of-a-kind water treatment plant, copied from New Mexico or somewhere like that, and so at the very end of these lovely designs about houses and playgrounds and woods, "...and this would be ideal to cool an AI center."

And, I just...I just can't escape the irony in that.

It's not what I want. Or I simply don't care and am leery of the consequences. No hydro fuel development facility for me. So I appreciate that others are running with the idea.

Another debut:

India’s new hydrogen train is a different beast

Rail cars powered by new fuel cell technology will run in a 89-km stretch carrying up to 2,600 travelers at 75 kph


India has rolled out a hydrogen train service as a pilot project using fuel-cell technology, joining an elite four-nation group that operates these trains.

The pilot project is envisaged to test hydrogen technology, as the world’s most populous country embraces clean technologies for the travel needs of its 1.4 billion citizens. Only Germany, Japan, the US, and China have hydrogen-powered rail services.

The hydrogen train will run on an 89-km stretch in the northern state of Haryana between Jind and Sonipat. It will have a maximum operational speed of 75 kph and can go up to 110 kph.

The train, which can carry up to 2,600 passengers, has ten cars – two hydrogen-powered driving cars and eight passenger coaches – making it the largest train in the hydrogen category.

Prime Minister Narendra Modi, who attended the inaugural ceremony on Friday morning, called it “a major leap towards green mobility” for the country in an X post.

Hydrogen fuel-cells convert hydrogen to electricity using an electrochemical process to run the train. The byproducts are water vapor and heat, making it an attractive alternative to diesel, which emits carbon dioxide, soot, and other exhaust gases.

However, it is less energy efficient than direct-electric trains which draw power from an overhead wire or third rail.

Refueling is quicker compared to recharging large batteries. The pilot project includes hydrogen storage and refueling facilities.

Hydrogen trains can easily fill the gaps in India’s 115,000 km railway network – among the largest in the world – where lines have not been electrified, or where electrification is not viable.

The overall carbon benefit is greatest when the hydrogen is produced using renewable energy, as India is doing.
Embed:

Germany tested the first hydrogen-powered passenger train – Alstom’s Coradia iLint – in March 2017 and rolled out regular commercial passenger service in 2018.

The two-passenger car train logged a 1,175 km journey without refueling in 2022.

Green lol. The movement named it after what plants look like, but it is about taking plant food from the air. They talk futures, and it’s all about the money and the control. Probably not in that order.

Looking up the ladder of power
in this world’s scale of rounders* running our destinies,
a little birdie told me
that it gets worse
where we can’t see.


* rounders was explained to me by a then girlfriend as “a dude who shouldn’t have money, but does”.


OK 🧐
The hydrogen fuel cell tech: steezie jinx. No argument there.

I think the main difficulty would be, as you mentioned, the hydrogen. Containment, including that hydrogen passe$ into metal$ and make$ them brittle. Hindenburg too, but those h+o flames go away upward, better compared to liquid fuel fires.


Herald from here. Been wet, expecting more mosquito buddies. I have a generous tolerance of them, plus I love rain. Cheers.
