From high costs to environmental impactCost is by far the leading challenge for geothermal development. Like their oil and gas counterparts, geothermal projects are extremely capital-intensive, with a longer payback and lower profitability than oil and gas projects. Drilling can easily represent half of the total cost of a geothermal project, especially in areas with complex geology and hydrogeology , and/or in remote areas with expensive logistics.
The right solution for every challengeOperators are principally interested in ensuring that their geothermal wells remain productive, robust and safe throughout their life, while maintaining operating costs at a minimum level. This requires identifying the right products that are capable of resisting the most extreme geothermal conditions while remaining cost-effective.
Innovation for geothermal energyThe geothermal industry is seeing a new wave of development, which presents fresh technical and economic challenges such as ultra-deep geothermal reservoirs (up to 5km depth) and closed-loop geothermal technologies
Ready to support geothermal growthInnovative technologies like these will help lessen the overall cost of geothermal projects. Geothermal energy may only play a modest role in today’s global renewable energy mix, but that is likely to change in the years to come as it becomes accessible worldwide.
