Unbelievable: China Turns Seawater Into Clean Fuel For Just Rs 24, Stuns Saudi, UAE, US | World News
Beijing: A breakthrough in China has created excitement in the global energy and water industry. A newly launched plant in Shandong’s Rizhao city has demonstrated that seawater at just Rs 24 per cubic meter can be converted into both drinking water and clean fuel in a single process. While scientists describe this as a turning point, economists call it one of the most disruptive innovations of the decade.
The project attracted worldwide attention because it produced two valuable resources, ultrapure drinking water and green hydrogen, with a single machine. Both are produced using nothing more than seawater and waste heat released from nearby steel and petrochemical plants.
For countries struggling with water scarcity and rising fuel costs, this development is seen as an example of what the future could look like.

According to a report in the South China Morning Post, this is the first facility of its kind anywhere in the world. It runs entirely on sea water and the excess heat released into the air by factories. Rather than allowing this energy to be lost, the facility’s engineers direct it into a system that turns the ocean into a source of fresh water and clean fuel. The design works on the principle of one input and three outputs.
One Input, Three Outputs
The only input is seawater combined with waste heat. From this, the system provides three different outputs.
First, it produces water suitable for drinking water. Every year, 800 tons of seawater is processed to produce 450 cubic meters of ultrapure water that can be used in homes, laboratories or industries.
The latter produces around 1,92,000 cubic meters of green hydrogen every year. It is considered one of the cleanest fuels in the world and can power everything from buses to industrial facilities.
Third, the process leaves behind 350 tons of mineral-rich brine, which is used in the production of various marine chemicals. Nothing is wasted and every step creates something useful.
Cheaper than Saudi Arabia and the USA
What surprises experts around the world is the cost. China produces fresh water from seawater for just Rs 24 per cubic metre. In countries like Saudi Arabia and the United Arab Emirates (UAE), known for the cheapest desalinated water in the world, the cost is still around Rs 42.
At California’s largest facility, the cost rises to around Rs 186 crore.
An interesting comparison also emerged in China. Tap water in Beijing costs 5 yuan, but sea-derived water at this resort costs only 2 yuan. Engineers say this difference shows how significantly the new process reduces costs.
Is It A Cheaper Fuel Than Oil?
Hydrogen has long been seen as the fuel of the future because it does not create pollution. The challenge so far has been that producing it requires enormous amounts of electricity and very pure water. Salt water damages machines, equipment clogs and electrodes wear out.
China’s new installation has overcome these obstacles by producing hydrogen directly from seawater without using any fresh water.
The amount produced at the facility is sufficient for 100 buses that will travel approximately 3,800 kilometers every year. Senior engineer Qin Jiangguang from Laoshan Laboratory explained the extent of the discovery: “This is not just about filling hydrogen cylinders. It is a new way to extract energy from the sea.”
Corrosion Problem Finally Solved
One of the biggest technical obstacles to hydrogen production from seawater is corrosion. Minerals such as magnesium, calcium and chloride ions damage equipment or settle on electrodes. However, the Rizhao plant has been running continuously for three weeks without a single outage, proving that the team has found a workable solution.
This breakthrough offers a ray of hope for coastal countries facing water scarcity and limited energy resources. Countries with long coastlines but limited fresh water may eventually be able to use the ocean not only as a source of water but also as a source of clean fuel.
