Hydrogen, as an energy source in transport and indus-try, is nothing new. Its applications have been known and used for decades. But it is the ambitious climate policy, and climate goals as well, that have spotlight-ed hydrogen in recent years. The EU Hydrogen Strate-gy, published on June 8th, tries to tackle the future challenges and boost the hydrogen market in Europe. But the question to be asked is how big the market could be not only European, but also global perspec-tive.

The current global hydrogen market is still in an em-bryo. It is estimated that around 74 mtpa of hydrogen are produced globally. The U.S. produces around 10 mtpa of hydrogen, slightly more than the EU. Also Poland with its 1 mtpa production has its place on the global map of hydrogen producers. But regarding current market situation there are two aspects to be mentioned. Hydrogen is mostly used as a resource in chemical and refinery processes and its application as transportation fuel is still marginal. Secondly, around 95% of hydrogen is as for now produced by transformation of fossil fuels. These are so called black, grey, blue or turquoise hydrogen. Some of them are produced with CCS or CCSU technology, which makes the fuel low carbon.
