While we are focused on geothermal and heat pumps at the core of our approach, we have been emphatically learning that these carbonization challenges require a systems approach. We consider the energy work that really needs done, the most efficient way to do it, and then and only then how geothermal heat pumps fit into the picture.
A large hospital complex engaged us to assess the potential for replacing 8 MWth of heat demand with geothermal heat pumps. We proposed an open loop system in the proven shallow hydrothermal aquifer and recommended a deeper test borehole to investigate a new thermal aquifer resource. Funding is being sought for the appraisal borehole.
A multi-national beverage company had us assess the potential of unexpectedly (well, to everyone except our Chief Geologist!) hot shallow aquifers. We designed a concept in which geothermal takes care of the demand, both hot and cold loads. A deeper test borehole is being procured.
A water utility engaged us to assess the opportunity to have a low/zero carbon heating and cooling geothermal system for a new building. The concept will be included in the initial planning application for the new build and there is the ambition to convert from gas for the whole site.
The DDCGE project funded through CASE is ongoing in Ulster University. Causeway has made in-kind contributions including analysis of the geothermal resources and modeling of Underground Thermal Energy Storage.
An aging oversized gas boiler needs replacing, and the client has grasped the opportunity to assess and design for a geothermal heat pump replacement. This will be a First Of A Kind (FOAK) and we are very excitedly working our way through the assessment. It promises to be a design one, build may application.
