Electric vehicles currently dominate the transition to clean mobility, but there are other options, such as hydrogen, that are becoming more popular, especially outside of public transport.One of the main advantages of this New technology Water is the only by-product of combustion, so there are zero greenhouse gas emissions. It can also refuel as quickly as a conventional internal combustion engine. However, in addition to the complexity of setting up the network, hydrogen stationOne of the main problems with this technology is that hydrogen is expensive to produce and often pollutes. Fossil fuels such as natural gas can be used to produce hydrogen. This is done by a method known as the Kvaerne process, or using water, one of the most abundant elements on earth. This is done by electrolysis, which splits water into oxygen and hydrogen. It used to require fresh water. And when choosing between drinking water and energy, the balance tilted towards the former. desalination It is a very power consuming process. But at Stanford University, they believe they have found a solution.
the key is New metal coating for electrodes It achieves decomposition of hydrogen. The coating consists of a layer of iron nickel on the nickel sulfide surface.the main obstacle seawater electrolysis That is, electrodes tend to attract chlorides, which corrode the material. Not only does the new coating prevent corrosion, it can also use 10x more power to speed up the process. The design is also energy efficient and can run on renewable power. In experiments, this was a PV solar cell. In the past, other companies and organizations have attempted to produce hydrogen from seawater. However, tests conducted by Alphabet or the Moonshot Factory, founded by the US Navy, proved to be unsuccessful.this technology project Although still in its early stages, scientists have already shown it to be a viable solution and believe it could usher in a new era of hydrogen fuel cells.
Which vehicles use hydrogen?
We already mentioned that hydrogen-based vehicles still have low market penetration, but that’s not the only area ripe for transformation. I have described recent developments in hydrogen powered train In the UK there are several initiatives around the world aiming to leverage this technologyFrom a hydrogen-powered plane developed by a company in Singapore to a hydrogen-powered ferry launching this year in San Francisco, USA.
One of the most advanced proposals is container to obtain hydrogen This allows it to replace the highly polluting fuels currently in use. And it is a diving equipment that can generate oxygen for divers.
