Kaishan, Halliburton Team Up on Advanced Geothermal, Green Fuel Projects
Kaishan Group and Halliburton have deepened their cooperation with a strategic memorandum of understanding centered on advanced geothermal development, especially enhanced geothermal systems (EGS), along with green hydrogen and green ammonia opportunities. The deal builds on earlier Indonesia drilling work and signals a broader push to combine Halliburton’s high-end well-construction capabilities with Kaishan’s geothermal equipment and project-development platform.
Partnership Background
The relationship did not begin with the July 2026 memorandum. In February 2026, Halliburton said it had won a multiyear contract from KS Orka Renewables, part of Kaishan’s wider corporate group, to support geothermal well construction at the PT Sorik Marapi Geothermal Power and PT Sokoria Geothermal Indonesia projects in Indonesia. That work covered directional drilling, cementing, drilling fluids, and drill bits across several development phases.
This matters because it shows the partnership was already operational before the new strategic agreement. Halliburton’s public description also framed the work as part of its low-carbon solutions portfolio and emphasized efficiency gains and cost reduction in geothermal drilling.
July MoU Scope
The July 22, 2026 announcement said Kaishan and Halliburton signed a Strategic Cooperation Memorandum to explore high-efficiency, low-cost EGS drilling and power generation solutions. The companies also said they would look for opportunities in geothermal development and other low-carbon and renewable energy fields, including green hydrogen and green ammonia.
The scope is notable because it goes beyond conventional geothermal power plants. EGS is the centerpiece, meaning the companies want to pair Halliburton’s drilling and reservoir stimulation skills with Kaishan’s modular geothermal generation equipment and broader project execution capacity.
Why EGS Matters
EGS is one of the most commercially important frontiers in geothermal because it aims to unlock heat resources in rock formations that are not naturally permeable enough for standard production. That makes drilling quality, hydraulic fracturing, and subsurface optimization critical, which is exactly where Halliburton’s technical strengths fit the partnership.
Kaishan’s role is equally important because the company brings modular geothermal power systems and experience across the geothermal value chain, from resource acquisition and exploration to manufacturing and operations. The public statements suggest Kaishan wants to use this combination to independently develop EGS resources and potentially position itself as a leading EGS developer.
Strategic Fit
The cooperation makes business sense on both sides. Halliburton gets a stronger foothold in geothermal, a segment that benefits from oilfield-style drilling expertise but is increasingly tied to the low-carbon transition, while Kaishan gains access to top-tier complex well-construction know-how.
The alignment also extends into emerging fuels. Both companies have linked geothermal power to green hydrogen and green ammonia, which suggests they see geothermal as a baseload energy source that can support electrolysis and downstream fuel production.
May Visit Signals
The July MoU appears to have been advanced by an earlier senior-level meeting in May 2026, when a Halliburton delegation led by Duane Sherritt, vice president of low carbon solutions, visited Kaishan’s headquarters. Reports from that visit say the team met Chairman Cao Kejian and General Manager Dr. Yan Tang and toured the Lingang manufacturing facility in Shanghai.
That visit is significant because it suggests the relationship was not a one-off commercial transaction. The plant tour reportedly included modular geothermal power systems and compressor equipment for hydrogen and CO₂ applications, which fits the later MoU’s emphasis on integrated low-carbon energy development.
Indonesia To Global
Indonesia is the clearest proof point for the partnership’s practical side. The Halliburton contract for SMGP and SGI shows the companies already have a live geothermal execution model involving drilling services and well construction.
The July memorandum widens that relationship from project delivery into strategic co-development. In other words, the collaboration is moving from “Halliburton supports Kaishan projects” to “both companies evaluate a wider portfolio of geothermal and low-carbon opportunities together.”
Green Fuel Angle
Kaishan’s green ammonia work in Kenya gives the Halliburton partnership an important commercial context. The company has already linked geothermal power to electrolysis-based hydrogen production and fertilizer manufacturing, which is why green ammonia appears alongside geothermal in the new cooperation language.
That broader framing matters because it suggests Kaishan is trying to monetize geothermal not only as electricity generation, but also as a platform for industrial decarbonization. In practical terms, geothermal can help supply the steady power needed for energy-intensive hydrogen and ammonia production.
Market Implications
If the cooperation advances beyond the memorandum stage, it could have implications for geothermal project economics. Halliburton’s drilling and stimulation expertise may help reduce well costs and improve subsurface performance, while Kaishan’s modular plant approach could shorten project timelines and lower capital intensity.
The main caveat is that the July announcement is still a memorandum, not a full binding project contract. Public reporting says the specific projects, commercial terms, and execution mechanisms still require further negotiation and confirmation in later agreements such as a strategic agreement or master service agreement.
Outlook
For now, the partnership looks like a credible step toward more industrialized geothermal development. The combination of advanced drilling, EGS ambition, and green fuel applications gives Kaishan and Halliburton a differentiated story in the global low-carbon energy market.
The most important thing to watch next is whether the memorandum converts into project-level contracts, especially in EGS and geothermal-linked hydrogen or ammonia applications. If that happens, the collaboration could become a useful template for scaling geothermal beyond traditional power generation.
