This page will be expanded with Darren’s full mining history, practical experience and equipment testing methods.
A Norwegian site report describes Kryptovault directing warm air into containers of firewood for producer Varma. The report identifies a practical drying partnership beside the mining operation.
GDA reports a heat-repurposing collaboration with Muttern Fastigheter that supplies hot air to local buildings using electricity described as hydroelectric.
Sazmining describes a 2.5 MW site serving a former hospital converted into a business centre. Separate water loops transfer heat to the building, with backup heating retained.
Hashlabs describes capturing heat from its Finland mining project and supplying it to a local district heating network.
MARA describes 1 MW of mining heat at 50–60°C, supplemented by heat pumps for a network whose peak winter requirement reaches 95°C.
MARA reports supplying heat at 55–78°C into an existing district heating network. At milder times, those temperatures allow direct integration without heat pumps.
SAIHEAT’s annual report describes a Bitcoin-mining operation in Marietta and greenhouse and fish-pond facilities heated with recovered hot water. Earlier filings also describe an Ohio demonstration facility.
Canaan announced a 24-month proof of concept with Bitforest. Heat from liquid cooled Avalon equipment would preheat greenhouse boiler intake water through a separate heat-exchange loop.
Genesis Mining and Swedish research and municipal partners developed a demonstration linking a mining container with a greenhouse. The project explored local food production using recovered heat.
Bitcoin Brabant describes moving industrial miners into a hydrangea greenhouse where heat was useful. Its retrospective explicitly says the family-run greenhouse operation ceased in 2023.
Irish Farmers Journal visited Tom Campbell’s anaerobic-digestion site and its Scilling Digital Mining installation. The project uses stranded electricity beside a farm biogas plant.
Lent Hill Ag-Grid Digital uses electricity from manure and food-waste digestion to supply a flexible mining container. The operator reports a 300 kW grid-export limit alongside a 1 MW mining unit.
