Eldsneyti

Eldsneyti refers to fuels used to power engines and heating systems. It includes liquids and gases that release energy when burned, derived from petroleum, biomass, or other feedstocks. In everyday language, eldsneyti covers gasoline (petrol), diesel, jet fuel, kerosene, liquefied petroleum gas (LPG), natural gas, and their blends or substitutes. Fuels are selected based on energy content, combustion characteristics, engine compatibility, and emission constraints. They are transported, stored, and distributed through global and local supply chains.

Common forms and applications include gasoline and diesel powering road vehicles; jet fuel powering aviation; kerosene and fuel oil used in heating and industry; LPG used in heating and cooking; natural gas for some heating and vehicles; biofuels such as biodiesel and ethanol as renewable alternatives; and synthetic fuels under development or pilot use. The choice of fuel affects efficiency, performance, and environmental impact, as well as infrastructure needs such as fueling stations and storage facilities.

Storage and safety are important considerations. Eldsneyti are highly flammable and can produce hazardous vapors. They require approved storage tanks, proper containment, and measures to prevent leaks and spills. Handling involves safety equipment, correct labeling, and procedures to minimize ignition sources. Transportation follows regulatory standards to reduce the risk of accidents and environmental harm.

Environmental and regulatory aspects: Combustion of eldsneyti releases CO2, along with pollutants such as nitrogen oxides and particulates. Emission standards and fuel quality specifications govern performance and environmental impact. Policies increasingly promote cleaner fuels, higher efficiency, and lower lifecycle emissions, including biofuels and gradual transitions to low-carbon technologies.

In Iceland, electricity and heating are largely supplied by renewable resources, reducing domestic use of liquid fuels for heating, though eldsneyti remains essential for aviation, heavy transport, and remote applications.
