Transportkütusena

Transportkütusena is a term used to describe fuels intended to power transport systems, including road vehicles, ships, aircraft and trains. It encompasses a broad range of energy carriers, from conventional petroleum fuels to renewable and low-emission options. The choice of transport fuel depends on factors such as energy density, fueling infrastructure, safety and cost, as well as environmental and regulatory considerations.

Common categories include fossil liquids such as petrol (gasoline) and diesel, which remain widespread due to established engines and networks. Biofuels, including biodiesel and bioethanol, are produced from biomass and can be blended with conventional fuels. Gaseous fuels such as compressed natural gas (CNG), liquefied natural gas (LNG) and liquefied petroleum gas (LPG) offer different storage and emission profiles. Electricity serves as a transport fuel in battery electric vehicles, while hydrogen can be used in fuel cells or, in some cases, combustion engines. Synthetic fuels or e-fuels produced from renewable energy and captured carbon are developed to reduce lifecycle emissions while using existing engines and infrastructure.

Key considerations for transportkütusena include energy density, storage requirements, refueling or charging infrastructure, safety, and the overall environmental impact from well to wheel. The suitability of a fuel varies by application: passenger cars, heavy road transport, aviation, shipping and rail each have different technical and economic needs. Policy frameworks, market incentives and investment in infrastructure strongly influence fuel choices and transitions, with ongoing efforts to reduce greenhouse gas emissions while maintaining reliability and affordability. The term thus reflects both technical possibilities and regulatory discussions aimed at decarbonizing transport.
