Gaseous fuels are traditional energy carriers and sources, in the form of natural gas, biogas, compressed natural gas (CNG), and liquefied natural gas (LNG). They play a crucial role in ensuring energy supply security, climate protection, and economic realizability. Gaseous fuels also serve as a key component in the mobility and transportation sector, and can be utilized as hydrogen derived from electrolysis using electrical energy from wind turbines (power-to-gas). Gas-based solutions make significant contributions to achieving sustainability goals, reducing greenhouse gas emissions, and promoting the transition towards a cleaner energy system.

Gas serves as the umbrella term for all gaseous energy carriers. This includes natural gas, gases derived from renewable sources such as biogas from fermentation and pyrolysis, as well as the wide range of hydrogen options. Each of these gases, sourced from different origins, possesses distinct properties and characteristics that need to be considered and potentially modified for different applications. Transport requirements also need to be taken into account, whether it be through transmission and distribution networks, as compressed natural gas (CNG) or liquefied natural gas (LNG), or bio-CNG / LNG via waterways, roads, and railways. This equally applies to natural gas with its source-dependent specific compositions. Among traditional fossil energy sources, natural gas has the lowest specific CO2 emissions. GWI has been working for years on sustainable solutions involving biogases and hydrogen for the future, always with an emphasis on optimized application.
