Geothermal Isn't Expensive: The Reservoir Always Has the Final Say Somewhere beneath a volcanic ridge, a drill bit is turning through rock that has not moved in two million years. It costs money every second it turns. And nobody on the surface — not the engineer, not the financier, not the minister who announced the megawatts — knows yet whether that well will produce steam or silence. That single moment explains almost everything people get wrong about geothermal energy. Geothermal is routinely described as expensive, slow, capital-hungry and haunted by drilling risk. Investors are reminded that tens of millions can disappear underground before a single megawatt reaches a grid. All of that is true. But it is not the whole truth. The uncomfortable question the industry keeps avoiding is this: is geothermal expensive, or is the way we develop geothermal making it expensive? Those are two completely different problems. One is geology. The other is us. Why Geothermal Refuses to Be...
China's Largest Geothermal Heating Project Cluster in Jing-Jin-Ji Takes a Leap Forward

On July 29, 2024, a significant milestone was reached in China's quest for clean energy. The China National Petroleum Corporation (CNPC) announced the approval of two pilot geothermal heating projects in Xianghe County and Dachang Hui Autonomous County. These projects, part of the largest geothermal heating cluster in the Jing-Jin-Ji (Beijing-Tianjin-Hebei) region, mark a significant step forward in China's clean energy transition.
Geothermal energy, with its abundant reserves, stable output, high utilization efficiency, and economic feasibility, stands out as a key player in China’s renewable energy strategy. Unlike fossil fuels, geothermal energy does not emit greenhouse gases, making it an ideal candidate for the country’s ambitious carbon reduction goals under the "Dual Carbon" strategy.
Recognizing the potential of geothermal energy, local governments in Xianghe and Dachang have been proactive in accelerating its development. Earlier this year, in January and March, CNPC's Dagang Oilfield inked agreements with these counties to collaborate on geothermal heating projects. The goal is clear: replace traditional coal and gas heating with clean, sustainable geothermal energy.
The scale of these projects is impressive. Together, they will provide heating for a staggering 2.4 million square meters of space. Following the agreement, CNPC swiftly mobilized its resources. Leading the charge was the Dagang Oilfield Exploration and Development Research Institute, which partnered with the Oilfield Production Technology Research Institute and the Oriental Geophysical Company. This powerhouse team delved deep into the geothermal geology of the two counties, tackling complex challenges such as the region's intricate structural features, rapid thermal reservoir changes, and unclear resource scales.
Their efforts have laid a solid foundation for the projects. Through meticulous research and analysis, they have pinpointed favorable geothermal well targets and refined the pilot project plans. This meticulous groundwork will pave the way for the next stages of feasibility studies and construction.
These geothermal projects are not just another step in Dagang Oilfield's geothermal industrialization journey—they are a landmark achievement. As these pilot projects progress, Dagang Oilfield is committed to ensuring they meet high-quality standards, are feasible, and ultimately, profitable. The aim is to create a demonstrative clean heating project that will set a precedent for the entire North China region.
With this development, China is once again proving its commitment to a sustainable future, showcasing the potential of geothermal energy as a cornerstone in the global fight against climate change. The success of these projects could very well serve as a model for other regions, both within China and beyond, looking to harness the power of the Earth for a cleaner tomorrow.

This is not the first time we have witnessed oil and gas companies venture into Geothermal bersek till they are coming up with one of the best techniques one can ever vouch for with Sage Geosystems being an example.
We are certain this could be strategic way of repurposing oil and gas fields into Geothermal and we at Alphaxioms we are very much keen on making stay ahead of the future of Geothermal.
