QHeat concept provides a sustainable and nearly emission-free solution for our most urgent problem – the use of fossil fuels and other non-ecological energy sources. QHeat produces renewable geothermal energy with innovative technology. This allows utilisation of geothermal energy for heating and also the return of energy to the bedrock when it is commercially feasible. The technology is well suited for building dense city areas as one medium-deep heat well can be used to heat and cool a whole city block.
Not only as an answer for preventing climate change QHeat’s technology provides a concrete answer to the challenges of the changing energy market. Along with heating and cooling, approx. 2000 meter deep heat wells can also be used as seasonal energy storages. QHeat’s technology allows 95 % reduction in CO2-emissions and provides an opportunity towards a more flexible energy market.
QHeat concept is more than traditional ground heat. Most importantly QHeat concept’s geothermal heat wells are much deeper – they reach the depths of 2000-3000 meters. Temperatures at this depth are significantly higher and thus much more energy can be produced.
Also, the heat well technology is more advanced allowing efficient heating, cooling and seasonal energy storage. QHeat concept as its energy production mode is local and distributed i.e. we can construct local low-temperature energy networks. This also allows lower temperature utilisation in individual buildings as well as energy exchange between the buildings in the energy networks.
During the heating phase using medium-deep geothermal wells the bedrock cools gradually. On the other hand, during cooling phase energy is brought down to the bottom of the heat well where this energy recharges the energy gap generated during the heating phase. This energy can be used again during the next heating phase. This energy charging deep into the bedrock can be done whenever energy is cost effectively available e.g. during summer when solar and wind power are excessively available. Similarly, several waste energy sources can be combined and stored into the heat well. This enables efficient circular energy economy.
