Geo-energy research
Energy transition requires a combination of energy sources, technologies and applications. An important role is reserved for geothermal energy. At present, this is mainly used in horticulture to heat greenhouses, but it is also becoming an increasingly attractive alternative to disconnect homes from natural gas. TNO also focuses on the storage of energy and CO2.

Martin Bloemendal
Functie:Lead scientist Underground Thermal Energy Storage and Associate Professor TU DelftI am a specialist in Underground Thermal Energy Storage (UTES) and work on various studies on utilization of sustainable heat by means of seasonal storage in the subsurface. In these endeavours I always consider the system as a whole, which means not only the subsurface system, but also consumers and the required facilities to utilize the available heat.
That is why I also have extensive knowledge of related and complementary techniques (ranging from well/borehole drilling and completion technology to heat pump, building facilities and control). My focus is not on the technical aspects only; I also work on organizational and policy-based issues concerning sustainable heating and cooling, as these are key for optimal and sustainable utilization of subsurface resources in practice.
