British scientists use cheap and simple ammonia for hydrogen storage

A recent study by a team of the British Science and Technology Facilities Committee (STFC) found that hydrogen is produced by decomposing ammonia, which is not only cost-effective, but also simple and efficient, and it is a storage and cost-saving aspect of on-demand hydrogen production in the field. The challenge provides a reliable solution.

Many people regard hydrogen as the best alternative fuel in the transportation sector, but its safety and how to reliably store it have always been a problem, and the cost of building a hydrogen station has remained high, greatly limiting the great prospect of hydrogen as a green fuel. Researchers say that new discoveries may solve these problems.

When ammonia is decomposed by cracking technology, nitrogen and hydrogen are obtained. At present, there are many catalysts that can effectively crack ammonia to release hydrogen, but the best catalyst is a very expensive metal. According to a report recently organized by the Physicist Organization Network, the new method does not use a catalyst, but is completed by two simultaneous chemical processes. The final hydrogen is as much as the catalyst, but the cost is much lower.

Moreover, the researchers said that the cost of ammonia production is very low; ammonia can also be stored at low pressure in a suitable plastic tank and then placed on the car; in addition, the construction of an ammonia station is as simple as the construction of a liquefied petroleum gas (LPG) station. Convenience, therefore, the latest research is expected to vigorously accelerate the pace of hydrogen as a green fuel for transportation.

The leader of the study, Bill David, said: “The new method is as efficient as the best catalysts available today, but the cost of using the active material sodium amide is extremely low. We can use ammonia to produce hydrogen on-demand and cheaply.” Professor Martin Jones, another inventor of the method, stated that they are currently developing the first low-power static demonstration system.

2015 will be a big step forward in the development and manufacturing of automobiles. Although people are enthusiastic about Nissan’s “Leaf” and Tesla’s “Model S” all-electric vehicles, many automakers will compete to develop next-generation fuel cell electric vehicles next year. For these cars, the battery is crucial, and the fuel cell is based on hydrogen. David Willis, British University and Science Minister, said: “This is undoubtedly the innovative technology we need. We are committed to reducing greenhouse gas emissions by 80% by 2050. The latest research may be able to greatly promote this goal. ."

David McKay, Chief Scientific Adviser, Department of Energy and Climate Change, UK, said: “We believe that there is no single solution for reducing the carbon emissions from fuels. However, the latest research shows that amino technologies deserve our further exploration. Moreover, The future is expected to have a major impact." (Liu Xia)
