”\u00a0Yes my friends. I believe that one day water will be used as fuel, and the hydrogen and oxygen that make it up, when used alone or simultaneously, will provide an inexhaustible source of heat and light at a density that coal cannot see.<\/em>\u00a0\u201d Jules Verne in his work \u201cThe Mysterious Island\u201d in 1875.<\/p>\n

Hydrogen comes from 95% fossil fuels<\/strong>\u00a0income . The goal of many countries is not fossil energies, which emit large amounts of greenhouse gases, but\u00a0from renewable energies<\/strong>\u00a0or to develop green hydrogen from decarbonised (including nuclear) sources .<\/p>\n<\/div>\n

What is hydrogen?<\/h2>\n
\n

6 things to know about hydrogen<\/strong><\/p>\n

    \n
  1. Dihydrogen<\/strong>\u00a0Hydrogen (its real name is systematically composed of two hydrogen atoms, its chemical symbol is H2), is produced by hydrocarbons (or fossil fuels such as coal, gas or oil) and water.<\/li>\n
  2. Contrary to what we think, hydrogen\u00a0is not an energy, but an energy carrier created from a primary source and produced by a chemical reaction. That's why it's always combined with other atoms.<\/li>\n
  3. There are three techniques for producing low-carbon hydrogen: gasification, water electrolysis, and steam-to-natural gas conversion.<\/li>\n
  4. Approximately 92% of the atoms in the universe are hydrogen atoms. It is the main element of stars and gaseous planets such as Jupiter, Saturn, Uranus and Neptune.<\/li>\n
  5. Today, hydrogen is used in refining, in the production of ammonia\u00a0(NH3)\u00a0for nitrogenous fertilizers and explosives, in the production of methanol in plastic manufacturing, and in the steel industry for iron and steel.<\/li>\n
  6. \u201cGreen\u201d hydrogen represents a future lever in the transition to carbon neutrality. However, it currently represents only 1% of the world's hydrogen.<\/li>\n<\/ol>\n<\/div>\n

    Green hydrogen, assets and constraints<\/h2>\n

    Production methods<\/h3>\n
    \n

    Dihydrogen<\/strong>\u00a0Since it is usually associated with another molecule, it must be removed to isolate the atom. Also, since dihydrogen consists of two hydrogen atoms, it must be split equally so that the molecule has only one hydrogen atom. Different methods of producing hydrogen:<\/p>\n

    Methane pyrolysis<\/strong>
    \nThis green hydrogen production system consists of the combustion of a mixture of CO (carbon monoxide) and H2 (hydrogen) in contact with coal or other biomass. Methane is used because it is the main component of natural gas and its atoms are simple in composition (CH4), so hydrogen is more easily extracted. In fact, the reaction of this process rejects CO2 in solid form. Therefore, it becomes easier to remove H2.<\/p>\n

    electrolysis of water<\/strong>
    \nThe task of water electrolysis is to split the water molecule (H2O) to extract hydrogen and oxygen atoms. This solution is undoubtedly the most used because there is no CO2 emissions. The reaction rejects oxygen only in the form of water.<\/p>\n<\/div>\n

    Electrolysis works by using electricity, which is very heavy. Also, making an electrolysis is very cute. Since this method is rentable, it requires the use of a small amount of carbon-containing electricity, which will be provided by nuclear, nuclear-fueled or a renewable energy intermediate such as solar panels. The loss of these renewable energies is a failure to build large numbers of electrolyzers that do not produce green hydrogen.<\/p>\n<\/div>\n<\/div>\n

    \n

    Conversion of natural gas to steam
    \n<\/strong>Steam reforming of natural gas is the chemical reaction of methane with water to produce a mixture containing CO2. Through this process, carbon dioxide can produce decarbonized hydrogen.<\/p>\n<\/div>\n

    Benefits<\/h3>\n
    \n

    We can use hydrogen to decarbonise some industrial sectors, store electricity or power transportation.
    \nHydrogen has great potential to contribute to reducing greenhouse gas (GHG) emissions.
    \nHydrogen, which is completely clean, does not emit CO2 and is very light. If mass produced, it participates in reducing global warming and is therefore an important player in the energy conversion.<\/p>\n<\/div>\n

    Limitations<\/h3>\n
    \n

    The storage of hydrogen poses a real obstacle to its use. It has a high mass energy density, but because it is very light, its volume is low.
    \nOne plan is to make it liquid by compressing it at a low temperature of -253\u00b0C (4l H2 = 1l oil).<\/p>\n

    Mass production of low-carbon hydrogen is necessary to create real positive changes to the climate. On the contrary, the production of small amounts of green hydrogen causes global warming.<\/p>\n

    Green hydrogen is very costly because it depends on electricity, which is very high today. It is also necessary to reduce the costs of renewable energies, electrolyzers and fuel cells, which are the mainstay of green hydrogen production.
    \nThe distribution of this green energy also requires huge infrastructures that must have production capacity powered by renewable energies, a transportation network to distribute them, and various storage areas.<\/p>\n<\/div>\n

    What are the uses of green hydrogen?<\/h2>\n

    Public transport<\/h3>\n

    hydrogen engine<\/strong>\u00a0The most suitable system for\u00a0fuel cell<\/strong>\u00a0is the use of . It's lighter and more efficient than batteries, and it's also great for the environment. Indeed, the cells work by combining the hydrogen contained in the engine with the oxygen in the air. This reaction produces electricity to power the vehicle's engine. The only waste product is clean water.<\/p>\n

    Fuel cells have been used to provide electricity in rockets since 1839. It is still used today to power rockets, as the first ones were used in the Gemini and Apollo space missions. Therefore, fuel cells are more easily selected to provide \u201cgreen\u201d engines for heavy vehicles. Indeed, to get enough power to run a truck, it would take a lot of electric batteries, making the engine very heavy.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    \n

    cars and trucks<\/strong><\/p>\n

    In France, transport is the leading sector emitting greenhouse gases, 30% of all GHGs. A renewable electrolysis powered\u00a0hydrogen vehicle<\/strong>\u00a0It will emit only 15 tonnes of CO2 compared to 45 tonnes for a diesel vehicle. This solution will reduce the carbon impact by 74% compared to a thermal engine vehicle.<\/p>\n<\/div>\n

    If hydrogen is converted into methane, it has the ability to store large amounts of electricity. Therefore, it can be used in the event of failure of replacements such as wind turbines or solar panels that are subject to intermittency. These are effectively climate dependent, so they may be subject to interruptions in electricity production.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    \n

    The biggest difference between electric and hydrogen vehicles is autonomy. While a hydrogen vehicle can travel up to 600 km and charge quickly, an electric vehicle charges more slowly.<\/p>\n

    trains<\/strong><\/p>\n

    55% of the railway lines in France run on electricity, the rest on diesel. That's why SNCF and other French companies are more\u00a0CO2\u00a0free fleet<\/strong>\u00a0Trying to distribute it.
    \nFor example, Alstom put its first passenger-carrying hydrogen train into service in Germany in August 2022. One\u00a0with hydrogen fuel cell<\/strong>\u00a0it works .<\/p>\n

    airplanes<\/strong><\/p>\n

    Airbus wants to participate in this new energy distribution and plans to launch it by 2035.\u00a0hydrogen planes<\/strong>\u00a0determined to produce. To do this, the company needs to produce certain products, lightweight fuel cells and acquire powerful electric motors.<\/p>\n<\/div>\n

    \n
    \n

    burning hydrogen<\/strong>\u00a0automatically generates heat, so we can consider replacing coal with hydrogen.
    \nFor example, producing iron and steel with coal emits large amounts of greenhouse gas emissions. A factory in Sweden uses hydrogen to produce iron. While the production of one ton of iron causes 25 kg of CO2 emissions, the use of coal causes 1850 kg of CO2 emissions for 1 ton of iron.<\/p>\n

    Steel production, which is done today by reducing iron ore through coal, could be produced tomorrow through decarbonized hydrogen.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    More and more companies are getting into the business of producing green hydrogen to help with the energy transition and reducing global warming. Because hydrogen is a dangerous gas, these companies must secure their facilities and protect their employees. That is why we are receiving more and more requests for hydrogen detection devices such as the\u00a0OLCT100\u00a0fixed\u00a0gas detector, the\u00a0X-am 2500 4 gas detector, the\u00a0GasBadge Pro\u00a0single gas detector or the\u00a0Spyglass IR3-H2 hydrogen or methanol flame detector<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    \u00a0Decarbonizing industries<\/h3>\n

    Worldwide development projects<\/h2>\n
    \n

    NortH2\u00a0project,<\/strong>\u00a0It is Europe's largest hydrogen production project, producing green hydrogen using renewable electricity obtained from offshore wind power off the coast of the Netherlands.<\/p>\n

    German\u00a0company H2Fly,<\/strong>\u00a0has been specializing in hydrogen fuel cells for aviation for several years. The first aircraft was successfully launched in 2016.<\/p>\n

    german company\u00a0Home Power Solution<\/strong>\u00a0is a pioneer in the production of domestic solar hydrogen power plants (picea). It forces individuals to consume their energy to stop carbon dioxide emissions.<\/p>\n

    Swiss company H2 Energy,<\/strong>\u00a0It has made it its mission to stop global warming by turning hydrogen obtained from renewable energies into an energy column.<\/p>\n
