A geothermal project sounds complex. The principle is not. We drill into hot rock, circulate a working fluid in a closed loop, and convert that heat at surface - into electricity, building cooling, industrial heat, or all three at once.
Modern geothermal is a closed-loop heat-mining process. We do not consume the rock. We do not consume the water. We extract heat - and return the cooled fluid to the same reservoir to be reheated. The same volume cycles for decades.
A geothermal well does not give up its heat in one shot. As the working fluid cools, each temperature band has a useful job. RT designs every project as a cascade - so a single hot-spring system pays back as electricity, then cooling, then drying, then tourism.
Each block in our process is mature and bankable. RT's role is integrating them into a Thai-context geothermal cascade - and de-risking the subsurface side with the drilling and reservoir DNA we already have in-house.
Organic Rankine Cycle turbines convert moderate-temperature geothermal heat (120–200°C) into electricity using a low-boiling-point working fluid. Ideal for Thai resources.
Heat-driven chillers (LiBr or NH₃) replace conventional electric chillers. Geothermal feed delivers chilled water for HVAC, building cooling, and data center loops - at a fraction of the grid load.
Decades of Thai oil & gas drilling experience translate directly. Slimhole rigs lower exploration risk and cost; directional drilling lets us hit the reservoir from a small, community-friendly surface pad.
Geological mapping, geophysical surveys, and 3D reservoir simulation define where to drill, how much fluid to circulate, and how the field will perform across decades - before any rig moves.
Cooled fluid is returned to the reservoir through the injection well. Pressure is maintained, the resource is preserved, and there is no net consumption of groundwater - geothermal stays sustainable across project life.
Each MWh and each ton of CO₂ avoided is logged with Digital MRV - making outputs auditable for green PPA, carbon credits, and ESG reporting from day one.
Geothermal is unfamiliar to many decision-makers in Thailand. These are the questions we answer most often - directly, without jargon.
Whether you operate a data center, an industrial estate, a hospital, or a hotel cluster - RTG's team can model the geothermal cascade that fits your load profile.
