Sustainable Geo Energy

Sustainable Geo Energy facilitates the energy transition by developing and sharing knowledge with our partners and customers worldwide. As we closely work together with operators, energy suppliers, energy intensive industries, SME and governments, we are able to take a creative and divers view. We focus on feasibility studies, risk assessment and monitoring. Our core expertise is in the field of applied geology and geo-engineering.

CO2 capture, utilization and storage

CO2 capture, utilization and storage is part of the energy transition. Sustainable Geo Energy has a CCUS track record of more than 20 years (i.e. EU FP7 CO2Remove; CATO-2, the Dutch R&D program for CO2 Capture and Storage). Within TNO the full CCUS chain is covered. Our expertise is based on the craft and creativity of our people in combination with experience from

  • Feasibility studies of potential CCS sites
  • Monitoring programs and risk assessment studies
  • Research programs on full scale demonstration sites, small scale in situ pilots and desk studies on CCUS boundary conditions, such as regulation criteria and volume estimates

Geothermal energy

Heat and electricity from geothermal energy is a sustainable source that is far from being fully exploited yet. It may help to meet 5-10% of energy demand in energy intensive regions. Theoretically, 40% of world energy consumption could be produced on a sustainable basis from the natural heat flow from the earth. Our focus is on geothermal aquifers in mature oil and gas basins and enhanced geothermal systems. You may draw from our expertise on the Earth's temperatures as well as from TNO's knowledge on petroleum exploration and production and CCUS translated to geothermal applications gained by:

  • Research programs on operational problems and pushing the limits for EGS
  • Mapping, resource assessment and full feasibility studies for geothermal energy
  • Monitoring programs and risk assessment studies
  • Technical support of government and industry including SME in promising regions, specifically in large scale urban (re)development and developing countries
  • Integration of locally produced heat or electricity in smart grids

Clean coal refers to a set of alternatives to use the world's large coal reserves in a more sustainable and environmentally friendly way. Some alternatives are already being applied, some still require major technological developments and innovations.

(Enhanced) Coal bed methane (E)CBM

Coal bed methane produces methane, captured in non-minable coals through wells drilled into the seam. The gas recovery can be increased by the injection of CO2, which is adsorbed by the coal enhancing methane release.
TNO research activities focus on:

  • Seismic data interpretation
  • Reservoir geology
  • Coal characterization
  • CO2 storage performance assessment

Underground coal gasification (UCG)

UCG converts non-mineable coal seams in-situ into a product gas. An oxidant is injected and then ignited. The generated gas is extracted through a production well. TNO research activities focus on:

  • Process control
  • Coupled modeling
  • Monitoring
  • Techno-economic calculations on the sustainable use of UCG syngas
