Terahash describes Kläger Group’s Hartha energy park with a 1.6 MWp solar array, a 350 kWh battery and a mining container able to absorb up to 500 kW. The container is intended to buy surplus left by industrial production, with storage and grid export also available.
Terahash describes a commissioned system at Nebona’s spice factory: a Heatcore HS20 with two Whatsminer M63 units uses surplus rooftop solar power and supplies hot water to a buffer tank. The existing heating system remains available.
SunBit reports fitting a Bitcoin Boiler alongside the oil boiler in a 200 m² Kotka home. An outdoor unit rejects unwanted summer heat and allows additional use of solar surplus.
SunBit describes a 2024 installation in a 3,000 m² industrial hall. Mining heat works alongside an air-to-water heat pump, reducing reliance on oil. The site also has a 30 kW solar array.
In November 2024, Deutsche Telekom announced a pilot with Bankhaus Metzler at RIVA Engineering in Backnang. Metis Solutions hosts the container and Telekom MMS operates the miners. RIVA has on site photovoltaic generation. The purpose is to collect field evidence for flexible use of surplus electricity.
Terahash documents a car wash using a 150 kWp PV canopy and up to 20 kW of water cooled mining. Heat serves wash water and winter floor heating. A 2,000-litre hot-water tank and a secondary heat pump help manage demand.
Ponderay Industries reported that Merkle Standard began operating a mining data centre at its paper-mill campus in 2022. The mill had entered bankruptcy in 2020 and was acquired in 2021. This is a reuse of industrial land and power infrastructure, rather than evidence of paper waste being converted into mining fuel.
Green Bitcoin Farm describes a developing finca concept linking solar and wind electricity, Bitcoin mining, and drying of moringa, herbs, fruit or spirulina with recovered heat.
Druk Holding and Investments describes using digital assets, including Bitcoin, to derive value from surplus hydropower while diversifying Bhutan’s energy system.
Blockstream documented construction of a Bitcoin-mining project with Block using Tesla solar and battery infrastructure, intended to demonstrate renewable-powered mining with public operating data.
