The world spends about $12 trillion a year on energy — and roughly 50% of it is lost through chimneys and exhaust stacks. Sidel CREN captures that waste and gives it back as clean power, water, and food.
There's a lot of energy-saving tech out there. What makes this different is the scale of what full deployment can achieve — at the power plant, at the cooling tower, in the data centre, and in the atmosphere.
One integrated retrofit built from proven technologies. The story is simple — every step below has its own page if you want the engineering.
Hot flue gas leaves the combustion process — full of particulates and paid-for heat.
Removes ~90% of particulates and recovers heat. Patented, self-cleaning, one moving part.
Recovers the remaining low-grade heat — and clean condensed water. Proven since 1978.
Novacab TESS thermal batteries bank the recovered heat in phase-change material.
Stored heat is converted to clean, dispatchable electricity — on demand.
Cleaned CO₂ and water vapor grow food year-round. What's left exits the stack clean.
Community-scale power plants (15–50 MW) built for efficiency, resilience, and pride — with exhaust repurposed into year-round greenhouse food production instead of dumped into the sky.
Sidel Systems' flue gas condenser has been recovering waste heat for industry for over four decades.
