According to independent research organisation TNO, the Netherlands could cover nearly 50% of its heating demand with geothermal district heating paired with heat storage.
In a recent article, TNO (Nederlandse Organisatie voor Toegepast Natuurwetenschappelijk Onderzoek) – a Netherlands-based independent research organisation – makes an argument that “geothermal energy coupled with heat storage in the soil can in time provide for a large part of Dutch heat demand.” In the same article, TNO makes the point that ‘a kind of IKEA package’ is needed to reduce the heat demand in homes.
TNO wants to pump more hot water from the deep underground and temporarily store it in shallow reservoirs. These could also act as a battery for solar heat and industrial residual heat. “In theory, we can connect two-thirds of the Dutch households to a heating network and feed half of them from geothermal energy”, says specialist Maurice Hanegraaf of TNO. Whether such a scale is realistic is uncertain, but the knowledge institution is serious about the large-scale use of the CO2-neutral, infinite heat source.
