Unravel the Geothermal Potential

Let's dive together into the world of existing Hydrothermal, EGS and AGS geothermal solutions and identify the problem that is resolved by GEIOS Hybrid technology.

What is Geothermal ?

Geothermal energy can make an important contribution to making the supply of heat sustainable, as it has almost no CO2 emissions.

Geothermal energy is a local source of sustainable energy, which is not dependent on weather conditions, day/night or seasonal cycles. It is a proven technology that has been successfully deployed in Europe, Africa, North & South America and Asia.

The geothermal technology is highly active in countries such as USA, Indonesia, Turkey, Iceland, France, Germany and Italy etc.. for decades. Below the surface of the Earth, from a depth of 500 metres to more than 3,000 metres, hot water is present in (porous) sandstone, limestone, hot rock, metamorphic or igneous strata. This heat originates deeper in the Earth's crust, and arises due to currents and radiation decay from the outer crust of the Earth.

GEIOS the new Innovation in Geothermal field

Innovative technologies promise to provide goods and services better, cheaper and in ways never envisioned before.

But often these technologies are ahead of the regulatory curve and stumble because the regulatory environment is designed in ways that exclude them.

One example is geothermal energy for distributed electricity production. Geothermal energy – broadly described as the natural heat of the Earth – is renewable, controllable and clean. Distributed generation – small-scale electricity production at or near where the electricity will be consumed – is reshaping how the world thinks about electricity grids.

GEIOS will play a major role in the distributed generation, which includes small-scale geothermal electricity generators that can serve isolated electric loads such as remote communities, islands or industrial sites, this also apply to special

When it connects to the wider grid, GEIOS generally interconnects at the higher voltage distribution level. Distributed generation differs from traditional generation sources, which tend to be large centralized power plants that are far away from electricity demand centres and must transmit their electricity over high-voltage transmission lines

Today's Geothermal Problem

FROM NATURAL CREATED RESERVOIR TO EGS MAN-MADE !

During the past decade, very low efforts have been made by governments and engineers to unravel the geothermal potential, their focus has only located on visible geothermal resources that is usually located around volcanic arcs and fully neglecting the areas where there is plenty of hot dry rock (HDR) and hot sedimentary aquifer (HSA).

This effort, in volcanic areas, has provided the basis for converting volcanic risk into a potential clean energy resource, especially in densely inhabited areas. Due to the increasing need for energy in emerging countries, it becomes necessary to characterize geothermal reservoirs as either low/intermediate-temperature resources (for heating and cooling of buildings, district heating, and greenhouses) or high-temperature resources (for electricity generation or co-generation).

Today, majority of high-temperature geothermal resources are exploited through open deep wells that are reaching depth between 1 to 5 km to reach reservoirs and which can be located in highly heterogeneous volcanic complexes or sedimentary basins, or old basement rocks.

For hydrothermal projects mainly called Mass Transfer System, the success of an exploration mainly rely on the reservoir permeability for hydrothermal or EGS with a main target to find an adequate enthalpy and a combination of flow, pressure, high reservoir recharge and temperature, usually in some countries receiving grants and support from international banks, when the defined set of combination is not reached, the exploration is a failure.

In other hand some exploration companies take advantage of the enthalpy and temperature to man-made the geothermal concession.

The company enhance through different engineering techniques to improve productivity, this configuration is called EGS standing for Enhanced Geothermal System, the company will drill into the permeable area, use a fracking method to create new pathways that will allow injected water to travel into the rock and be captured by production wells from the end of the pathways leading to a method that reproduce the perfect natural hydrothermal conditions so the geothermal project can produce electricity at low-medium or high enthalpy.

Although such techniques are in some areas very efficient, they raise hard problems like :

- Pollution with Co2, Nox, Sox emission,
- Social acceptability,
- Fracking Method that can require more than 4 million of gallons per well,
- Larger landscape as the injection wells are located separately from the production wells,
- Seismicity as per the difference pressure into the rock between pre-heated or cold water,
- Injection or reinjection of low temperature into the rock is reducing the life of the reservoir (need proper management)
- Parasitic load,
- Silicon dioxide pushing the maintenance cost at higher level and affecting the LCOE,
- Hydrogen Sulfide,
- High Amount of water to produce 1 MW (in average 63l/s),
- Process in binary system to separate the brine that require separators,
And many more.

GEIOS Exogeothermal Solution

EVOLUTION FROM MASS TRANSFER TO HEAT TRANSFER !

GEIOS system is considered as a AGS (Advanced Geothermal System), this hybrid structure allow to enhance the efficiency of the geothermal solution and get benefits from two source of renewable energy that are complimentary and in full abundance.

Compared to Hydrothermal or EGS system our system is targeting the impermeable rock structure where the temperature is over 300°c, and which is usually located right below the water reservoir, these temperatures in some countries like Indonesia are usually found at 3000 to 4000 meters or less.

Conscious that the exploration is a high cost and drilling wells without any visibility on the resource is totally not responsible, GEIOS has developed solutions to harvest the gradient at subsurface through satellites imagery, lithographic and stratigraphic datasets, these will be used to locate the hot dry rock and prepare the necessary geologic and geostrategic report necessary to start and initiate the project.

Focusing only on HDR and HSA, GEIOS can locate this geothermal system outside the range of volcanic arcs, which make our system unique for remote and marginal areas.

GEIOS is developed with specialists with a strong data science background, allowing our company to use artificial intelligence at several steps along the project, our use of AI range from the drilling to enhance the rate of penetration and improve our stratigraphic reports to the presence of a digital twin to enhance the operation.

We address the depletion by combining one of the most secure resource in earth, the solar energy, our hybrid structure is using thermal solar flat panels connected to the primary network and that will be able to overcome the depletion of the reservoir or the rock, the heat capture by the solar flat panels will be injected underground which will be slowing the exhaustion of rock and allow the lower part of the crust below the rock to regenerate over conduction or convection.

To enhance, the GEIOS revolution is located in the lower part of the well (bottom connected to the rock) , the GEOCASING TM is using graphene nano oxide particles and he will enhance the heat transfer making the organic fluid hot quickly and capable to scale up in term of power - quasi on demand.

As the drilling as become more affordable and more quicker than before with the use of AI solutions based software making the geothermal GEIOS a viable solution at this day.

GEIOS resolve today's problem for EGS - some AGS & Hydrothermal solution by :

- GEIOS close loop system is isolating the emissions of Co2, Nox, Sox and other components,
- GEIOS System is totally safe with positive impacts on social,
- There is no fracking method used or water injected with GEIOS,
- No Seismic Risks as no fracking
- GEIOS use a close loop with a working synthetic fluid, which remove the risk of parasitic load
- GEIOS is not impacted by Silica or Silicon Dioxide
- GEIOS doesn't need water injection for this low and medium enthalpy system
- GEIOS for high enthalpy, the water needs are mainly gathered from the sea or ultra-filtrated (non potable) to produce steam
- There is no brine impact

What make GEIOS so special in the market ?

GEIOS is the solution for an efficient, clean, green, scalable and long term geothermal application

AI and ML for geo-exploration

By Focusing on hot dry rock and hot sedimentary aquifers, GEIOS avoid seismic activities and other type of issues related to volcanic areas, our methodology of exploration differ from the existing methods, we based our methodology on several datasets that run into a Machine Learning to define specific rules based on stratigraphic and lithographic measures, the use of satelites and GIS is allowing us to evaluate the surface gradient in a very efficient way and to optimize unnecessary exploration funds.

A global network of EPC

GEIOS work in very close relationship with world renowned EPC & Drilling companies, our integrated approach is unique and to prove it, every geothermal power plant installed is under a key performance in the LCOE through contract of 10 years, to do so, we ensure through contract that the power is constantly generated at the capacity factor defined, we also ensure that the resource is fully replenish with constant monitoring and the presence of Digital Twin system and finally we garantee that GEIOS operation cost is always on the range of the one agreed.

GEIOS Revive existing wells for geo-exploitation

Repurposing existing well sites for geothermal production can reduce overall costs by reusing the existing infrastructure including the well, well pad, access road and electrical infrastructure. The cost of well abandonment and reclamation creates an incentive to transfer the liability to another entity or defer the liability. Using the well site to produce geothermal energy may be one way to achieve this. If geothermal energy is then produced from the well site, this may delay abandonment and reclamation requirements due to active energy production. It would also deal with potential issues of lease trespass.

The reuse of suspended or abandoned well sites for geothermal energy can make geothermal production more economical, reduce the overall environmental impact of geothermal development through brownfield development and address the numerous inactive oil and gas wells
