QuestAir Technologies, a Canadian company that develops proprietary gas purification systems, is set to refocus its business strategy on working in the biogas market. They used to make hydrogen purification systems marketed (not very successfully) by ExxonMobil, they will make methane purifiers that upgrade biogas for injection into existing natural gas pipelines. And they already sold ten of these. Can we use this for trend analysis or is it just a single company taking a step? You decide.
