An Extraordinary and Inexpensive Way to Extract Hydrogen from the Sea Found

Hydrogen energy is seen as a huge potential for global energy needs. However, obtaining it cleanly is essential for a clean future.

Green hydrogen production can only be qualified as “green” as it is renewable energy and not negative waste. A new study by RMIT University is not only producing green hydrogen from the sea, but also doing it very cheaply, without producing waste.

Hydrogen Production Is Not As Clean As It Seems

Research into green hydrogen production is currently advancing at a rapid pace as countries around the world seek to gain ground in what is expected to become a huge global market for clean fuels. Countries with easy and abundant access to the sea, such as Turkey, have a strong potential in hydrogen energy. On the other hand, the only solution for hydrogen production for countries like Turkey, which has little fresh water resources, is again sea water.

But it is more difficult to obtain hydrogen from seawater than from freshwater sources. Because there are purity, corrosion and microorganisms to be overcome. Even if these problems are solved, when hydrogen is obtained from sea water, toxic chloride is released. However, the benefit portion is much greater if these problems are overcome. When you use seawater, not only is your water supply free, it can also be used to nourish the soil. That’s why there are many teams working on electrolysis techniques that produce green hydrogen from seawater.

New Method Enables Clean and Cheap Hydrogen Production

Scientists at RMIT, Australia have announced a new approach with great potential for producing highly efficient, low-cost green hydrogen directly from seawater without producing chlorine.

Dr Nasir Mahmood, lead researcher of the project, said, “The biggest obstacle to using seawater is the chlorine that can be produced as a by-product. If we were to meet the world’s hydrogen needs using seawater without solving this problem, we would produce 240 million tons of chlorine per year, which is three times the world’s chlorine needs. “There’s no point in replacing hydrogen produced from fossil fuels with hydrogen production that could otherwise harm our environment.”

According to Dr Nasir, the new method developed not only bypasses carbon dioxide, but also produces no chlorine. In experiments, it was found that the new catalyst developed exhibits extraordinary efficiency and completely suppresses the formation of chlorine. However, the cost ($1.40/kg) was also greatly reduced. At the end of the day, the research team wants to scale up. If the efficiency level can be achieved on a large scale, it can be possible to collect hydrogen from the sea without producing waste.
