There apparently are millions of armchair experts who badmouth about all the dangers and impossibilities of making, storing and transporting hydrogen. They all say that H2 leaks like water through a sieve and that hydrogen causes containers to become brittle, as fragile as a clay pot. They are being ignored by the engineers who have made, stored and transported hydrogen for more than 80 years. Hydrogen is used to make the fertilizer that grows the food you eat, to increase the octane of gasoline and in many industrial processes. It has been stored and transported safely for many decades.
The natural gas that is used in huge quantities for industrial processes such as making cement and for residential heating must stop putting CO2 into the atmosphere. Green Hydrogen is a possible substitute.
Hydrogen, made from fossil fuels, mainly natural gas but also coal, must be made without adding CO2 or methane to the atmosphere, so there are many plans to develop green hydrogen electrolysis plants as replacements.
This article from the International Monetary Fund talks about the plans to develop green hydrogen plants.

Quote (scroll 4 paragraphs past “New Focus on Renewables”) “”Enthusiasm around green hydrogen is raging. Projects costing billions of dollars are under consideration in Mauritania, Algeria, Egypt, and other countries. A German developer and Mauritania signed a memorandum of understanding with a consortium for a $34 billion project with annual capacity of 8 million tons of green hydrogen and related products.
Hydrogen projects could help keep energy flowing from the Southern Rim to the Northern Rim. The infrastructure to transport hydrogen is already under development, although projects so far focus on the intra-European market. A large chunk of the prospective hydrogen investments may end up in Europe, with Italy and Spain gearing up to become big producers. Portugal, Spain, France, and Germany signed an agreement to build a Mediterranean pipeline that would supply 10 percent of the EU’s hydrogen by 2030. The energy ministries of Italy, Germany, and Austria signed a letter of support for the development of a hydrogen-ready pipeline between North Africa and Europe involving Italy’s gas grid operator.””
Those armchair experts are being treated like doormats: the engineers and developers are wiping their feet on the armchair experts as they walk all over them.
