As we have seen in previous articles<\/a>, hydrogen is an element that can come from different sources. If we take advantage of renewable energies to generate it, we get green hydrogen, which is totally clean and sustainable.<\/strong><\/p>\n

Regardless of its origin, hydrogen presents some challenges when it comes to storing and transporting it. This is because hydrogen is the lightest and least dense element of all<\/strong>, so a small amount takes up a very large amount of space. It is therefore necessary to densify it, to compress it, so that its storage and transport is cost-effective and efficient. Once compressed, it allows us to store and transport it in specialized containers, such as tube trailers, for later use.<\/p>\n

When compressing hydrogen, it must be taken into account that it has some characteristics different from other gases, such as, for example, that unlike other gases that heat up only when compressed, hydrogen also heats up when decompressed<\/strong>. In addition to the fact that it is a gas with a high explosive power and high flammability, it is necessary to take a series of precautions when compressing it. To solve this problem, Hiperbaric has developed a refrigeration system<\/strong> that effectively cools hydrogen in the compression process of its Plug & Play compressors<\/a>.<\/p>\n

Hydrogen is a very interesting element as an energy carrier because it has the highest energy per mass unit of all fuels<\/strong>. Compared to gasoline, for example, hydrogen has a calorific value of 120 MJ\/kg compared to 44.3 MJ\/kg for gasoline. The problem it presents is its low density, approximately 13 times lower than air, and this is where its compression comes in.<\/p>\n
