Gas represents 21.5% of EU’s primary energy consumption. It is the dominant source of energy for households (32.1%).
Around 40% of households are connected to the gas network. On average, they spend EUR 700 on gas, 2.5% of their average income (EUR 27,911). However, this conceals considerable differences among Member States.

Catalysts play a crucial role in the production of hydrogen (H2). There are various methods for producing hydrogen, and different catalysts are used depending on the method. Some common methods for producing hydrogen include:
Steam Methane Reforming (SMR): This is the most widely used method for producing hydrogen and involves the reaction of methane (natural gas) with steam in the presence of a catalyst, usually nickel. The reaction produces carbon monoxide (CO) and hydrogen (H2).
Electrolysis of Water: In this process, an electrical current is used to split water into hydrogen and oxygen in the presence of a catalyst, typically platinum or iridium.
Photobiological Production: This method uses microorganisms such as algae to produce hydrogen through the process of photosynthesis. Catalysts are not typically used in this method, but researchers are investigating the use of catalysts to increase the efficiency of the process.
Catalysts are used in these methods to increase the rate of the hydrogen-producing reaction, and to promote the desired product distribution. They can also improve the efficiency of the process, reduce costs, and improve the overall quality of the hydrogen produced.
Hydrogen is often categorized based on the method used for its production and the source of energy used. Some common types of hydrogen are:
Green Hydrogen: This is hydrogen produced using renewable energy sources such as wind, solar, or hydropower. It is considered to be the most environmentally friendly type of hydrogen as it does not emit greenhouse gases during production.
Blue Hydrogen: This is hydrogen produced from natural gas using steam methane reforming (SMR) in combination with carbon capture and storage (CCS) technology. The idea behind blue hydrogen is to reduce the carbon emissions associated with hydrogen production from natural gas by capturing the carbon dioxide (CO2) produced during the reaction and storing it instead of releasing it into the atmosphere.
Grey Hydrogen: This is hydrogen produced from natural gas using steam methane reforming (SMR) without the use of carbon capture and storage technology. It is considered to be the least environmentally friendly type of hydrogen as it releases large amounts of CO2 into the atmosphere during production.
Turquoise Hydrogen: This is hydrogen produced from the electrolysis of water using electricity generated from renewable energy sources. It is considered to be a more sustainable type of hydrogen compared to blue hydrogen, as it eliminates the need for carbon capture and storage technology.
In summary, green hydrogen is considered to be the most environmentally friendly type of hydrogen, while grey hydrogen is considered to be the least environmentally friendly. The use of hydrogen as a clean energy source is expected to increase in the future, particularly as the focus on reducing greenhouse gas emissions and transitioning to a low-carbon economy becomes more important.
