2 Purification units Air | Hand Gas PRODUCTION Hydrogen is produced by the separation of chemical elements of which the H atom is a component and by the mobilization of an energy source. Today, a major part of the hydrogen production is from natural gas and more generally, approximately 95 % of hydrogen production still comes from fossil fuels (natural gas, oil, coal). The production of hydrogen thanks to a renew able or nuclear energy source (or by steam reforming of natural gas if the process is associated with a CO2 capture, storage and recovery unit) is called “low-carbon hydrogen” and quickly became an environmental and political priority, especially around Electrolysis. CHARACTERISTICS The dihydrogen H2 molecule, made up of two hydrogen atoms, is commonly called “hydrogen” and was discovered in 1766 by the British physicist Cavendish. Under normal conditions of temperature and pressure, hydrogen is a colorless and odorless gas but also the lightest element of the periodic table. It is soluble in water up to 1.6 mg/L at 21 °C. It is the simplest member of the family of chemical elements and the most abundant one in the universe (main element of the Sun and stars). However, it is rarely found alone on and in the Earth, and is very often an integral part of various organic materials and, more importantly, water (H20). Depending on its temperature and pressure, it can be found in different states: gaseous, liquid, solid, metallic and triatomic. Here, we will only concentrate on hydrogen in its gaseous state. The different ways of producing hydrogen are classified by colors: Natural state Electrolysis with electricity coming from Renewable Energy Sources (RES) Thermal splitting of methane pyrolysis (CO2 produced is solid and not gaseous) Hydrogen produced from different processes including natural gas, with Carbon Capture Utilization and Storage (CCUS) techniques involved The earliest known important chemical property of hydrogen is that it burns with oxygen to form water (H2O), it was therefore made famous for its usage in the process of nuclear fusion. But it is now even more famous for its extremely low density, allowing it to be an energy vector to answer the problematic of electricity storage. Therefore Hydrogen is today widely considered as one of the key features that will play a major role in the world’s energy transition. Electrolysis with electricity from nuclear power plant High temperature catalytic splitting of water using nuclear heat Chemo-thermal electrolysis through direct nuclear power and heat Hydrogen can be used for a variety of Industrial, Residential and Mobility applications: - Chemical industry | Production of ammonia and other fertilizers (50 % of global consumption) - Petrochemical industry | Sulfur removal | Creation of gasoline and diesel (hydrocracking) | Methanol production (synthesis of amines and alkanes by hydrogenation) - Food industry | Production of margarine and butter (fat hydrogenation) - Welding | Atomic Hydrogen Welding (also called Plasma) - Glass production | As antioxidant or shielding gas when coupled with nitrogen - Electronics manufacturing | Production of semiconductors, LEDs, displays, etc - Aerospace | Rocket’s engines (liquid form) - Housing | Lighting, Heating - Hydrogen Refueling Stations (HRS) for ‘’Green Mobility’’ | Fuel Cells Electric Vehicles, FCEVs Production from fossil fuels in general (often Steam Methane Reforming - SMR) OMEGA AIR d.o.o.
