Investment in QHeat that specialises in geothermal heat generation We advised the Finnish Climate Fund in investment in Quantitative Heat Oy (QHeat). The funding will be principally allocated to the purchase of new, more efficient drill equipment for drilling medium-deep heat wells. Geothermal heating is part of the solution for transitioning away from the use of fossil fuels for heating as heat wells generate heat energy-efficiently and without combustion. Medium-deep heat wells can also be used for cooling real estates, in which case they can store energy to even out seasonal variations. Geothermal heat production has a great deal of potential for climate action in applications such as low-emissions heating solutions.
