The three megawatt pilot program, introduced on January 6, 2026, companions Canaan with Bitforest Investment, a Canadian agency targeted on sustainable infrastructure.
The venture deploys 360 liquid-cooled Avalon computing servers at Bitforest’s tomato greenhouse facility. In response to Canaan, the system captures roughly 90% of the electrical energy consumed by the servers as warmth, producing water temperatures exceeding 75°C. This sizzling water preheats the consumption for the greenhouse’s electrical boilers by means of a closed-loop warmth change system.
Making Mining Work for Farmers
Conventional greenhouse operations in chilly climates face substantial heating prices. Massive services usually depend on fossil-fuel boilers to keep up optimum rising situations year-round. In Canada, a number of areas have adopted carbon pricing insurance policies to encourage lower-emission heating alternate options.
Canaan’s system integrates immediately into the greenhouse’s current heating infrastructure. The warmth captured from mining tools reduces the extra power wanted to achieve goal temperatures. This strategy eliminates the necessity for industrial cooling towers that standard liquid-cooled information facilities require.
“This program will enable us to measure, mannequin, and scale warmth restoration for agriculture in colder climates,” stated Nangeng Zhang, Canaan’s chairman and chief govt officer. “Liquid cooling permits us to output high-temperature sizzling water above 75°C, making compute warmth immediately usable for greenhouses.”

The 24-month pilot targets 95% uptime for the mining tools. Canaan estimates the all-in energy value at $0.035 per kilowatt-hour, which incorporates electrical energy, operations, troubleshooting, and upkeep. The corporate states the mixed system will flow into as much as a million tonnes of sizzling water yearly.
Following Historic Precedent
The idea of utilizing Bitcoin mining warmth for agriculture isn’t completely new. In 2018, Kamil Brejcha, co-founder of Czech cryptocurrency change NakamotoX, efficiently grew tomatoes in a five-acre greenhouse heated completely by mining tools. The venture produced what turned often called “cryptomatoes,” which had been even served as bruschetta at a Bitcoin Amsterdam occasion.
Extra lately, corporations like Heatbit have shipped dual-purpose units that mine Bitcoin whereas heating properties. A number of third-party corporations have tailored current mining {hardware} for area heating functions. Nevertheless, Canaan’s Manitoba venture represents a major scale-up to industrial agricultural operations.
Bitcoin Mining’s Inexperienced Transformation
The broader Bitcoin mining trade has undergone substantial adjustments in its power profile. In response to a Cambridge study launched in April 2025, sustainable power sources now energy 52.4% of Bitcoin mining operations. This contains 9.8% nuclear energy and 42.6% renewables comparable to hydropower, wind, and photo voltaic.
This marks a dramatic shift from 2022, when solely 37.6% of mining used sustainable power. Pure gasoline has changed coal as the one largest power supply at 38.2%, whereas coal utilization plummeted from 36.6% to only 8.9% over the identical interval.
The examine estimates Bitcoin’s annual electrical energy consumption at 138 terawatt-hours, representing roughly 0.5% of worldwide electrical energy use. The community’s estimated annual emissions stand at 39.Eight megatonnes of carbon dioxide equal.
Institutional Demand Drives Change
Distinguished investor Kevin O’Leary has repeatedly emphasised that institutional adoption of Bitcoin relies on mining sustainability. The “Shark Tank” star notes that lower than 1% of establishments globally presently maintain cryptocurrency as an asset class, largely resulting from environmental, social, and governance considerations.
“Some establishments desire, or demand, that the Bitcoin they purchase be mined sustainably,” O’Leary defined in an interview with Cryptonews. He predicts important institutional capital will circulation into Bitcoin as soon as sustainability requirements are constantly met.
Many giant firms keep ethics and sustainability committees that display investments earlier than allocation. These committees typically filter out property that don’t meet particular ESG standards, making a barrier for Bitcoin adoption no matter value efficiency.
Financial Pressures Form Innovation
The Bitcoin mining trade faces important financial challenges that make effectivity improvements essential. The April 2024 halving occasion lower block rewards from 6.25 to three.125 Bitcoin, immediately slashing miners’ main income supply. In the meantime, mining difficulty continues reaching file highs as extra computing energy comes on-line.
These pressures have pushed tools payback intervals to exceed 1,200 days—the longest in Bitcoin’s historical past. With transaction charges contributing lower than 1% of miner income, operators should discover artistic methods to enhance profitability and scale back operational prices.
Warmth restoration tasks like Canaan’s Manitoba facility deal with each financial and environmental considerations. By offering supplemental heating to agricultural operations, the mining tools creates further worth past Bitcoin manufacturing. The greenhouse operator reduces direct heating prices whereas the mining operation doubtlessly qualifies for carbon credit or different incentives.
Some mining corporations have pivoted toward synthetic intelligence and high-performance computing providers to diversify income streams. AI information facilities can generate roughly $25 per kilowatt-hour in comparison with Bitcoin’s $1 per kilowatt-hour, making such conversions financially enticing regardless of excessive infrastructure prices.
Actual-World Testing and Scalability
Past power reuse, Canaan plans to guage key efficiency indicators beneath precise working situations. The venture will measure warmth restoration effectivity, system stability, and working and upkeep necessities. This information will assist decide whether or not the mannequin might be replicated throughout Canada’s agricultural sector and related cold-climate areas.
Bitforest’s concentrate on year-round tomato cultivation makes constant warmth provide essential, particularly throughout harsh Manitoba winters. The venture will take a look at whether or not high-density computing infrastructure can virtually function a supplemental warmth supply moderately than merely venting extra power into the ambiance.
Canaan, based in 2013, shipped the world’s first ASIC Bitcoin mining machines and is acknowledged because the world’s second-largest Bitcoin mining {hardware} producer. The corporate accomplished its preliminary public providing on the Nasdaq International Market in 2019 and continues increasing its power effectivity initiatives.
The Sustainable Mining Path Ahead
Canaan’s Manitoba greenhouse venture demonstrates how Bitcoin mining can combine with conventional industries to create mutually useful outcomes. The 24-month pilot will present essential information on whether or not industrial-scale warmth restoration represents a viable path for making cryptocurrency mining extra sustainable and economically resilient.
As institutional buyers more and more demand sustainable mining practices and financial pressures pressure innovation, tasks that seize and reuse mining warmth could grow to be normal moderately than experimental. The success or failure of this initiative may affect how the trade addresses each profitability challenges and environmental considerations within the years forward.
