How a Startup Is Supplying a Whole City With Heat From Bitcoin Mining

North Vancouver will be the world’s first city to be heated by bitcoin mining.

MintGreen, a Canadian cleantech cryptocurrency miner, is working with Lonsdale Energy Corp. to supply heat to the city of North Vancouver in British Columbia from bitcoin mining.

The heat source will be introduced in 2022 and will prevent 20,000 metric tons of greenhouse gas per megawatt from entering the atmosphere compared with natural gas, according to a statement shared with Reacon.

MintGreen’s proprietary “Digital Boilers” recover 96% of the electricity used for bitcoin mining as heat that is then used to supply communities and service industrial processes.

The company uses an “immersion” technology that captures the heat generated in mining and goes to hot water utilities known as “District Energy,” which is then distributed to the customers, MintGreen’s CEO, Colin Sullivan explained to Reacon in an interview.

The utility has about a hundred buildings for the heat and MintGreen will sell it the heat in a contractual long-term agreement, Sullivan added.

On March 16, digital asset manager CoinShares said it participated in MintGreen’s seed investment round, noting that the miner’s “immersion” system captures and transfers the heat generated by crypto mining servers to industrial scale hot water utilities.

Using heat from bitcoin mining is not new, rather, it has been happening around the world on a smaller scale. MintGreen’s aims to have the system up and running by winter of next year in what would be the first deployment of the company’s technology on a large scale, according to Sullivan.
