Companies: QAR ��

Experts at oil giant ExxonMobil have recommended funding for a prototype hydrogen purifier developed by gas purification specialist QuestAir Technologies.

AIM-quoted QuestAir develops and supplies proprietary gas purification systems for oil refining, biogas production, natural gas processing and fuel cell plants. The company has a joint development agreement with ExxonMobil, which has carried out an internal review of QuestAir's Pressure Swing Adsorption (PSA) system.

This review has now recommended funding the construction and testing of a PSA prototype at one of ExxonMobil's refineries. No money has yet been paid or authorised, but Canada-based QuestAir, which also has development agreements with Shell Hydrogen and FuelCell Energy, is treating the review's recommendation as an important milestone.

Last month, Growth Company Investor said QuestAir's shares, then a depressed 50.5p, would do well if ExxonMobil decided to do a deal. They are now 89p, up 4p today, and it remains true.

Growth Company Investor’s recommendations consistently perform, with average percentage rises across all tips up over 30% in the last 3 years. Subscribe today with a free 30-day no obligation trial.
