Kaasupohjaisia

Kaasupohjaisia is Finnish adjective meaning gas-based or gas-derived, used to describe things whose basis or primary input is a gas. The form kaasupohjaisia is the partitive plural of kaasupohjainen, which combines the noun kaas u (gas) with the suffix -pohjainen to indicate foundation or basis. The expression is common in technical and scientific Finnish, especially in energy, chemistry and process engineering contexts.

In energy technology, kaasupohjaisia solutions refer to systems that rely on natural gas, biogas or synthetic gas as the primary energy carrier. In chemical engineering, gas-phase or gas-based processes (kaasupohjaisia reaktioita) describe reactions and separations that occur in the gas phase. In materials science or industrial design, the term can describe methods or products where gases constitute a fundamental input or medium.

Linguistically, kaasupohjaisia is used to modify plural or mass nouns in the partitive; the singular form is kaasupohjainen. The term is often found in policies, technical reports and academic texts when contrasting gas-based approaches with other pathways, such as sähköpohjaisia (electric-based) or biopohjaisia (bio-based) alternatives.
