WHY GASIFICATION? – Artec Energy

Gasification converts organic materials into hydrogen and carbon monoxide, i.e. syngas, which can subsequently be converted into energy. Until recently, the cost of a gasification unit did little to justify its need, as fossil fuels and land capacity remained relatively cheap and abundant.
