maakaasun

Maakaasun is a fossil fuel consisting primarily of methane (CH4), with smaller amounts of other hydrocarbons and inert gases. It is used for heating, cooking, electricity generation, and as a chemical feedstock. Maakaasun is found in underground reservoirs and is often stored or transported in gaseous form through a network of pipelines, or converted to liquid form for international transport.

Formation and extraction

Maakaasun forms from ancient organic matter subjected to heat and pressure over millions of years. It can occur in reservoirs on its own (non-associated gas) or together with crude oil (associated gas). Before it can be used, it is extracted by drilling and then processed to remove water, hydrogen sulfide, carbon dioxide, mercury, and other impurities, ensuring it meets pipeline and end-user standards.

Processing, transport and storage

After processing, maakaasun is delivered via pipelines to households and industries. For long-distance or international transport, it is often processed into liquefied natural gas (LNG), which is cooled to very low temperatures, or compressed natural gas (CNG). LNG is shipped in specialized tankers and regasified at import terminals. Storage is achieved in underground facilities or LNG tanks to balance supply and demand.

Uses and chemical role

In addition to burning for heat and power, maakaasun serves as a feedstock for chemicals such as ammonia, methanol, and other petrochemicals. It acts as a flexible energy source that can complement renewables, though its combustion emits carbon dioxide and other pollutants.

Environmental and safety considerations

Methane leaks contribute to greenhouse gas emissions, making efficient systems and leak detection important. Odorization helps leak detection for safety, and regulatory frameworks govern exploration, production, transport, and storage to mitigate risks to communities and ecosystems.

Global context

Major producers include the United States, Russia, Iran, Qatar, Canada, and China, while large consumers are Europe, Asia, and North America. Markets are shaped by pipeline networks, LNG trade, and energy-security considerations.
