Shvash gas being harvested on Gelgelar
Shvash gas provided a less expensive, albeit inferior, option compared to the gas fueling mini-flamers used for lighting smokes. To boost pressure within a flamer's gas container, it was frequently combined with superior gases.
During the Cold War era, which saw conflict between the Galactic Republic and the reconstituted Sith Empire, Suudaa Nem'ro, a Hutt crime lord, engaged in mining operations to extract shvash gas from a deposit located on Nal Hutta. His competitor, Voontara Fa'athra, also extracted gas from the same source through operations within the Rust Yards; however, Fa'athra's refining capabilities did not match Nem'ro's.
The cultivation of Shvash gas represented a significant economic activity on the world of Gelgelar, where its applications included heating and powering cooking devices. On Gelgelar, farmers utilized pumps affixed to repulsor barges to gather gas from the atmospheric clouds above the marshlands, as well as from subterranean pockets within the mud. The Gelgelar farmers sold their shvash gas pressure tanks to Vleen Argoe at the Shvash Gas Cooperative situated in Gelgelar Free Port. Vleen would then consolidate the gas into larger storage units and distribute them to freighter captains, who then transported the gas to mini-flamer producers like Blycks.
