GreenFire Energy Inc. deploys closed-loop technology to unlock continuous geothermal energy. The company developed GreenLoop, a technology that exploits typically inaccessible geothermal resources.

GreenLoop was designed to be a versatile technology that enables power generation (extracting heat from underground) and also a number of additional high-value applications including mineral extraction, hydrogen production, and energy storage.

GreenLoop technology is composed of GreenLoop Modeling and GreenLoop Designs.

GREENLOOP

GreenLoop Modeling

A system for assessing the potential of a given geothermal resource and modeling the performance of alternative closed-loop geothermal designs to determine the optimal configuration.

GreenLoop Designs

Are the physical attributes of a closed-loop system including the depth of the well, the architecture of the pipe system (e.g., coaxial, multilateral, U-Loop), the sizes and specifications of materials, the type of working fluid to be employed, Downbore Heat Exchanger (DBHX) to transport the heat and, in some cases, a Surface Heat (SHX) is also available.

PROJECTS

GreenFire Energy successfully demonstrated GreenLoop technology at Coso, California, USA, in 2019. This project was funded in part by the California Energy Commission, Shell Oil, the Electric Power Research Institute, and J-POWER of Japan with in-kind contributions from the Coso Operating Company and other industry partners. During the project, the technology was tested with different working fluids (water can supercritical carbon dioxide) and field scale applications.

February, 2024 | Philippines

GreenFire Energy appointed Alberto R. Dalusung III as a representative in the Philippines to assist in business development for geothermal projects, leveraging his 40 years of experience in the local renewable energy sector.

February, 2024 | San Francisco, California

GreenFire Energy and Energy Development Corporation received a USTDA grant to implement GreenLoop™ technology in the Mahanagdong Geothermal Field in Leyte, Philippines, aiming to boost geothermal power production from idle wells.

April, 2024 | San Francisco, California

GreenFire Energy and Stoic Transitional Resources announced a partnership to repurpose idle geothermal and oil/gas wells using GreenFire’s GreenLoop® and Stoic’s Flux Crossover technology.

April, 2024 | San Francisco, California

GreenFire Energy, U.S. Navy, and the Defense Innovation Unit launched a project to explore implementing GreenFire’s GreenLoop® technology at Naval Air Facility El Centro, California.

April, 2024 | Olkaria, Kenya

Kenya Electricity Generating Company approved GreenFire Energy’s GreenLoop® technology for a pilot project at the Olkaria Geothermal field, aiming to generate electricity from an underutilized well and expand geothermal energy production.

GreenFire Energy develops energy projects in partnership with owners of geothermal fields or oil and gas wells.

Capital cost per MW depends on multiple factors, such as underground temperature, well depth needed, type of rock.

GreenFire Energy will perform a preliminary analysis to estimate power generation and costs and they prioritize projects where they can offer cost-effective energy solutions. Owners can provide financing for smaller projects, and GreenFire Energy can provide financing for larger projects.

GreenLoop Modelling

• GreenLoop includes proprietary modeling to assess geothermal wells, resources, and existing infrastructure to determine techno-economic feasibility of projects and optimize the energy potential of geothermal resources. Analyses include well and reservoir modeling using simulations and 3D models. GreenFire Energy maintains a global database of geothermal wells.

• Closed-Loop Architecture: Closed-loop installations circulate various working fluids through a sealed system to access the high temperatures required for economic energy extraction. The working fluid can be supercritical CO2 to find a carbon sink solution.

• Advanced Thermodyanmic Modeling: GreenLoop modeling considers both customer specific well data and previous analysis of data from many types of wells within GreenFire Energy's database.

• Aggregation of Relevant Intellectual Property: GreenFire has acquired or licensed a broad spectrum of advanced, patented technology from multiple other companies (e.g.: Blade Energy patented close loop system) to offer the most complete set of capabilities for closed-loop geothermal energy systems.

• Influences from Big companies: GreenFire Energy was influenced by Baker Hughes to develop a sophisticated well cost model for closed-loop geothermal projects, and has retained Blade Energy to confirm its internal thermodynamic models. Finally, Reaction Engineering performed a detailed computer modeling analysis to prove that sCO2 will create a thermosiphon within specified well conditions.

GreenFire Energy solutions are comprised of technologies and services that span the full geothermal project lifecycle:

• Resource analysis and modeling

• Engineering services

• Construction and installation

• Operation and maintenance.

Their power generation solutions have specific applications for:

• Geothermal Well Retrofit: optimizing geothermal power production for existing wells and geothermal resources.

• Expansion Within Field: to scale geothermal projects by boosting production from existing fields and is often used to expand production from pressure- or water-depleted fields.

• Greenfield Projects: for the development of new wells in new geothermal resources.

• Oil and Gas Well Retrofit: to use abandoned oil and gas wells to produce geothermal energy.

• De-risk Conventional Projects: In case a conventional well fails to produce as planned, a GreenLoop Down Bore Heat Exchanger can often be inserted into the failed well to generate power.

In the case of Direct Use, the company focuses on heating and cooling, hot springs and de-risking conventional projects.
