Canaan has unveiled a proof-of-concept project that combines Bitcoin mining with agriculture by using recovered heat to power a commercial greenhouse in Manitoba, Canada.
The 3-megawatt pilot deploys liquid-cooled mining equipment housed in containerized modules at a tomato-producing greenhouse operated by Bitforest Investment.
Instead of releasing excess heat into the air, the system captures it through a closed-loop heat exchanger and uses it to preheat water for the greenhouse’s electric boilers.
Canaan estimates that around 90% of the electricity consumed by the mining servers can be transferred to the heating system, though final performance will be confirmed once the project is fully operational.
Beyond energy efficiency, the initiative allows Canaan to evaluate system stability, maintenance intensity, and cost reductions compared with conventional data centers.
The design could help reduce reliance on fossil-fuel heating while lowering both capital and operating costs in cold regions with carbon pricing pressures.
