New technology! Breakthrough in hydrogen AG10 battery technology

Recently, the Australian Commonwealth Science and Technology Research Organization (CSIRO) announced that it has developed a set of "hydrogen-ammonia" conversion technology based on metal films, which can effectively solve the existing problems of hydrogen AG10 batterys and improve the practicality of products. Moreover, this technology has been put into practical use. It is reported that the first batch of hydrogen AG10 battery vehicles based on this technology have been used in Toyota Mirai and Hyundai Nexo, and have been successfully tested on the road. This technology may be promoted in the future, but the time period may be very long. After all, any new technology is a long process from development to testing to commercialization, and it is not completed overnight.

This technology converts hydrogen fuel into NH3, increases the storage capacity and stability of the product, and extracts hydrogen with the help of "membrane reactor" technology when it is used, solving the problem of low temperature or high pressure storage of pure hydrogen fuel and safety issues.

The new system uses metal films to separate hydrogen and oxygen.

It should be pointed out that since hydrogen will make ordinary natural gas stainless steel pipelines embrittled (and require high pressure), the hydrogen energy industry needs a new set of pipeline infrastructure. In addition, hydrogen is a medium with low energy density, so it also requires a very special storage system to save energy.

This usually means storing hydrogen at high pressures of 350-700 bar (5,000-10,000 psi), and liquid hydrogen at a temperature of -252.8°C (-423°F), where it ‘absorbs’ metals as impurities such as hydrides, causing embrittlement.

Many of these problems are solved by combining hydrogen-nitrogen into ammonia (NH3).

The CSIRO system can chemically store hydrogen energy in the form of ammonia, so that it can be transported over longer distances and easily converted to high-purity hydrogen that can power AG10 battery vehicles when it arrives at its destination.

Ammonia can be stored at room temperature and has been widely transported for many years. Since Australia intends to become a major exporter of hydrogen energy, easily converting hydrogen energy with the help of catalysts is undoubtedly a brilliant solution.

The last thing to consider is how to recover hydrogen with sufficient purity.

The CSIRO solution is to use "membrane reactor" technology to incorporate it into a modular device that can be installed and used at the time of delivery (such as a AG10 battery vehicle hydrogen refueling station).
