Cancarb Limited initiated its annual maintenance outage efforts on April 1, 2022. While the outage on the carbon black plant has been safely and successfully completed, the power plant will continue to be offline for an extended period. Due to the unexpected extent and magnitude of repairs that were determined to be required, power operations are now expected to resume in mid-July.

While the power plant is offline, waste heat from the thermal carbon black process will be released through the bypass stack until the power plant resumes operations. This will be performed in compliance with the Company’s approved operating conditions.

The waste heat power plant is an integral part of the thermal carbon black process and allows Cancarb to reliably deliver clean electricity to the City of Medicine Hat. Since commencing operations in 2000, the power plant has delivered over 3,500,000 Mwh of waste heat-fueled electricity, offsetting the carbon footprint of other forms of electric generation.

Progress updates on this outage will be provided at

Hydrogen Fuel Cells

Elastomer Sealing Performace in Hydrogen Fuel Cells using Thermax 990. Partnership with RD Abbott, Cancarb, & Arlanxeo.


Thermax® application Refractories Thermax® carbon black can improve performance of monolithic, castable, carbon brick and basic carbon brick refractories. It can enhance resistance to thermal shock, heat, chemicals and active slag, increase refractory density, and improve in-situ carbide formation. Castables containing Thermax® require less water to reach normal casting flow, resulting in higher density and […]
