Hydrogen at €3 per kilo: has China really cracked the code?

Hydrogen for three euros per kilogram. It sounds like a pipe dream — but Chinese researchers say it is already within reach. Over the past months, a wave of scientific breakthroughs from China has promised to finally make green hydrogen affordable. But how solid are these claims, and what do they mean for hydrogen mobility?

The pump price: expensive, but more nuanced than it looks

At the pump, drivers in the Netherlands and Belgium currently pay between €15 and €25 per kilogram of hydrogen. On the face of it, a daunting number. But the comparison with petrol and diesel is more complex than that single price per kilo suggests.

A hydrogen car uses less energy per kilometre than a petrol car. Vehicle tax also matters: hydrogen vehicles in the Netherlands are exempt or pay a reduced rate. Once those factors are taken into account, hydrogen is already competitive with expensive petrol or diesel in many situations. The fuel cost calculator on H2 Rijders (h2drivers.com/nl/waterstof-of-benzine) works this out based on your car, driving habits and province. The default calculation shows that a hydrogen driver can already be nearly €450 per year better off than a comparable petrol driver — even at today's pump prices.

That does not mean hydrogen is cheap. Compared to a modern electric car or an efficient diesel, hydrogen at the pump is still more expensive today. But the message is clear: the price does not need to fall to zero — it needs to reach a level that competes fairly with the realistic alternative.

What China is claiming

Several Chinese research teams have published promising results in leading scientific journals over the past months.

A team from the National Center for Nanoscience and Technology developed new electrodes based on metal-organic frameworks (MOFs) — extremely porous materials engineered at the molecular level. Energy consumption was just 4.11 kWh per cubic metre of hydrogen, and the electrodes remained stable for over 5,000 hours. The calculated production cost: $2.71 per kilogram (Nature Chemical Engineering).

A second team, from China Agricultural University and Nanyang Technological University, replaced the energy-intensive oxygen evolution reaction with the oxidation of glucose from agricultural waste. The process yields formate as a valuable by-product, and including that revenue the researchers calculated a net production cost of just $1.54 per kilogram (eScience).

Researchers at Tianjin University tackled yet another bottleneck: the requirement for ultrapure water. Their adapted PEM electrolyser reportedly performs just as well on ordinary tap water, without loss of efficiency or increased wear — simplifying installations and reducing costs (Nature Energy).

China's industrial push

Beyond the lab, China is investing at industrial scale. Chinese manufacturers produce electrolysers for around $343 per kilowatt, compared to roughly $1,200 in the West — a gap of over 70 percent. Bloomberg analysts estimated that cheap Chinese electrolysers could reduce global green hydrogen production costs by 30 percent. By 2025, China was already producing over 220,000 tonnes of green hydrogen per year — more than the rest of the world combined.

From lab to reality: a big step, and big questions

These breakthroughs deserve nuance. All results were achieved in laboratory conditions, at small scale and under controlled circumstances. The real test is whether the technologies hold up at megawatt scale, with variable energy inputs, over years of real-world operation. Methods relying on glucose or agricultural residues also face a logistical challenge: sourcing those feedstocks at industrial scale is far from straightforward. And the price of green electricity — the single biggest cost factor in electrolysis — varies enormously by region. In the Netherlands, grid tariffs are so high that even optimistic scenarios result in €5 to €6 per kilo in production costs.

What does this mean for hydrogen drivers?

Pump prices will remain high for years to come. Laboratory production costs are not the prices drivers pay: distribution, compression, fuelling infrastructure and taxes all add to the bill. But the direction is clear: the technology race to make hydrogen cheaper is accelerating, and China is leading the way.

In the meantime, want to know whether hydrogen already makes financial sense for you? The H2 Rijders fuel cost calculator at h2drivers.com/nl/waterstof-of-benzine works it out based on your car, annual mileage and province — and shows immediately whether driving on hydrogen already saves you money compared to petrol.
