Australia Tests Ammonia-Hydrogen Fuel Batteries for Cars

The Commonwealth Scientific and Industrial Research Organization of Australia has tested a new fuel cell technology in which hydrogen is not stored but generated as it is consumed. The main working substance here is ammonia, which is much safer than hydrogen in terms of fire and in addition contains twice as much energy as liquefied hydrogen. It is possible that it will become the fuel of the future.

The ammonia-hydrogen battery consists of an ammonia tank, a special membrane and a controller. It is the membrane design that Australian engineers are most proud of - it allows you to extract the purest hydrogen from ammonia, filtering out impurities. The required gas is burned in the combustion chamber of the machine, the excess enters the atmosphere. This is mostly normal nitrogen, so there is no talk of harm to the environment.

And it is also cheap, since the synthesis of ammonia from the same hydrogen and atmospheric nitrogen was invented a century ago and is used on an industrial scale all over the world. The substance is easy to store and transport; to refuel the fuel cells, you do not have to build complex complexes, plus it is a potentially renewable form of energy - all components are taken simply from the planet's atmosphere and processed products go there. The first vehicles with new powertrains, Toyota Mirai and Hyundai Nexo, have been successfully tested.

And now the same Toyota and Hyundai are racing to invest in this new industry, despite the fact that there are still very few hydrogen cars in Australia. There will not be so many of them in the next couple of years, but the constructed plants for the preparation of ammonia fuel will be able to supply the giant Asian market. There, especially in cities choking on exhaust from cars, similar technologies await with open arms.
