Topic

Large scale seasonal thermal energy storage, often forgotten but cannot be ignored 

Speaker

Dr. Martin Bloemendal | TNO

Organized by
Ass. Prof. Silvia Gaastra-Nedea

Introduction

Sustainable energy has received substantial attention over the last years/decades. Heat is the largest part of the worldwide energy requirement (space heating/cooling, industry, etc.). As with many other renewable or sustainable energy sources, also with heat, the biggest challenge is dealing with the variability in the availability and demand. Heat storage is one of the major solutions to match heat availability to demand. Aquifer Thermal Energy Storage (ATES) and Borehole heat exchangers are, therefore, among the important geothermal energy technologies needed to utilize sustainable heating and cooling systems of buildings – and in particular, provides cheap and large scale storage. Both, high quality research and education as well as large scale adoption of UTES technology are needed during the coming decades at national and international level.

About the speaker

Martin Bloemendal is a specialist in Underground Thermal Energy Storage (UTES) and works on various studies on utilization of sustainable heat by means of seasonal storage in the subsurface. In these endeavors he always considers 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 he also has extensive knowledge of related and complementary techniques (ranging from well/borehole drilling and completion technology to heat pump, building facilities and control). His focus is not on the technical aspects only; he also works 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. At TU Delft he works on various projects to further develop UTES and teach courses at various levels and faculties.

Next to his appointment at Delft University of Technology he has a leading position on UTES at TNO, the Dutch Geological Survey. The combination TNO-TU Delft allows him to develop proof of concept of new ideas at the university and subsequently implement these in pilot projects with industry in TNO projects (bridging science to practice).
