Subsurface utilisation for the
energy and heating transition

Our mission

CJM Consultancy is a start-up that aims to contribute to a more sustainable future society. We share our expertise about utilisation of the subsurface in the energy and heating transition and educate and consult in a holistic and straightforward way, so it is understandable to everyone. We believe that better and more efficient utilisation and integration of resources and technology that are already there is key to a sustainable future.

We identify subsurface use cases, their potential role in local and regional renewable heating and cooling solutions. Based on this, we provide strategic and tactical advise on the technical potential on different levels: from a pre-feasibility study to parcel-level. By identifying potential integrations with other systems and analyse potential risks associated with the use cases, among which also the economic and societal risks, we take a holistic perspective.

Our work

An example of our previous research was focused on determining the technical potential of shallow geothermal heating for residential housing for the entire German state of Baden-Württemberg, while taking thermal interference (efficiency reducing property of geothermal energy) between boreholes into account to gain realistic insights. The study can be read here.

Other examples of areas of our expertise are:

  • Identifying subsurface energy potentials (heating/cooling, storage) and linking them to energy demand.
  • Scenario development regarding (potentially positive) impact on the electricity grid & financial impact compared to other renewable solutions (e.g., air-source heat-pumps, biomass).
  • Share our knowledge and provide insight to both technical and non-technical stakeholders (policy-makers, authorities, students et cetera) about the potential uses of the subsurface.
