There are other - much faster - methods, but they are also costlier, involving ion exchange resins or molecular sieves. This is based on the assumption that the water would be purified using the cheapest method available. That means that the cost of water purification for the production of a ton of hydrogen would be $2,432 (2,065 euro). However, electrolysis needs as much as 18 tons of water - not accounting for losses during the process - to produce one ton of hydrogen. Looks To Delay The WorldвЂ™s Most Controversial Pipeline Once Again For a ton of water, that would be $135.14 (114.72 euro). At a power consumption rate of 0.717 kWh, the distillation of a liter of water, then, would cost $0.14 (0.1147 euro).

The cost of electricity for non-household users in Germany was an average of $0.19 (0.16 euro) per kWh as of last year. Germany is the country with the most ambitious plans for green hydrogen. This doesnвЂ™t look like much at first glance, but letвЂ™s see how things look on a larger scale. Regarding the electricity cost, distilling a liter of water requires 2.58 megajoules of energy, which translates into 0.717 kWh, on average. This method is cheap because it only needs electricity, but it is not fast. Speaking of water purification, organic chemists explain that the simplest way to do this is by distilling it. Accounting for losses, the ratio is closer to 20 tons of water for every 1 ton of hydrogen. In other words, one ton of hydrogen actually needs not nine but 18 tons of water. According to the same source, water treatment systems typically require some two tons of impure water to produce one ton of purified water. The process of water purification, for its part, is rather wasteful. The water that the electrolyzer breaks down into constituent elements needs to be purified

But to get these nine tons of water, it would not be enough to just divert a nearby river. One industry source told Oilprice that the production of one ton of hydrogen through electrolysis required an average of nine tons of water. But electrolysis, besides electricity, needs water. When hydrogen advocates talk about the bright future of the technology, they focus on the costs associated with the electricity needed for the electrolysis. The process is performed in an installation called an electrolyzer. Electrolysis is the process of breaking down water into its constituent elements - hydrogen and oxygen - using an electric current. What nobody seems to want to talk about is water. There is much talk about the falling costs of solar and wind and how they will make green hydrogen viable very soon. According to proponents of the technology, green hydrogen - the kind produced through electrolysis powered by solar, wind, and other renewable energy sources - is the best way to decarbonize heavy polluter industries. Gigawatt upon gigawatt of green hydrogen capacity is being planned across Europe, Asia, and Australia.
