About Company:
TAKEnergy is a Calgary-based clean tech company developing small-scale radial vane expanders that convert the energy lost in natural gas pressure letdown stations into clean, carbon-free electricity. Their innovative TERVEX™ system operates at 1–50kW scale and uses fewer moving parts than traditional turboexpanders, enabling simple, low-maintenance installations that produce reliable base-load power without combustion. TAKEnergy’s solution offers utilities and municipalities a cost-effective and scalable way to recover energy while improving grid resilience and reducing emissions.

Project Title:
TERVEX Pilot Deployment at a Pressure Letdown Station

Challenge Area:
Grid Decongestion at the System Level

Focus Areas:

  • Waste energy recovery from gas infrastructure

  • Small-scale microgeneration

  • Grid reliability and congestion relief

  • Distributed power generation

  • Clean energy innovation for municipal systems

Project Objectives

  • Deploy and operate a 25kW TERVEX system (1 x 25kW unit) at a natural gas receipt or regulation station in Medicine Hat

  • Demonstrate electricity generation from natural gas pressure letdown without gas consumption

  • Evaluate grid congestion relief and emissions intensity at the distribution level

  • Showcase modular scalability of the technology for wider municipal applications

  • Provide cost-effective, low-maintenance distributed energy that operates as a firm resource

Project Summary

TAKEnergy’s pilot project introduces its proprietary TERVEX™ radial vane expander system to Medicine Hat’s gas infrastructure. The system captures the pressure drop from natural gas regulation stations and converts it into clean mechanical shaft power that drives a generator—without combusting or consuming any gas.

The proposed deployment consists of one 25kW unit, enabling scalable output based on gas flow. This modular design allows the system to operate efficiently during low or high flow periods, producing anywhere from 1kW to 25kW as needed. The electricity generated meets grid specifications while using a slipstream connection to avoid disrupting the main pressure reduction system.

The project will test the system’s performance under real-world conditions and assess its potential to offset significant infrastructure upgrades.

Expected Impact

  • Grid Resilience – Provides local and firm power in congested areas, supporting stability and redundancy

  • Economic Benefit – Validation of a projected LCOE of $0.07/kWh at 60% utilization, dropping to $0.03/kWh at 95%

  • Scalability – Modular design allows flexible deployment across gas pressure differential infrastructure

  • Emissions Reduction – Validation of 59 tCO₂/year avoidance from a single 25kW installation

  • Grid Congestion Relief – Validation of on-site generation and grid-decongestion potential
