TRLUP – Selective PSRV for Methane Emission Reduction from Uncontrolled Storage Tanks

Uncontrolled atmospheric, fixed-roof tanks often “breathe” straight to air through relief valves and hatches, releasing methane. Many small or remote sites can’t justify flares or VRUs, so we’re developing a Selective PSRV, a membrane-based vent that lets nitrogen and oxygen out while holding back methane and heavier hydrocarbons. In our Lab2Market Validate work we spoke with lots of stakeholders who confirmed the need and pointed out key gaps: limited real-world data on vent-gas composition, an unclear path for safety and standards approval on the tank roof, and uncertain treatment of these emissions in Alberta, alongside practical issues like very low pressure, cyclic breathing, cold weather, and condensables.

This four-month TRL project turns those findings into action. We will fabricate small membrane coupons and modules, conduct bench tests under simulated tank-vent conditions, and develop a simple measurement and verification plan to demonstrate reductions credibly. We will also map the compliance pathway and evidence needed for approval, as well as develop a clear cost and payback picture. We will capture what’s unique in an IP snapshot and line up pilot venues and roles, with University of Calgary resources and Tourmaline’s West Wolf Lake facility as strong candidates. By the end, we aim to deliver a concise commercialization package and move the concept from early validation to pilot-ready, advancing from roughly TRL 2–3 toward TRL 3–4.
