Sedimentary Geothermal Systems

Conventional geothermal systems, also called hydrothermal systems, work in places with existing heat, water, and permeability. These systems benefit from convective flows of hot water constantly rising from the deep to recharge their production zones. Hydrothermal systems first produced electricity over 100 years ago. Many next generation geothermal technologies have attempted to generate power in areas without these resources, however, very little power has been produced.

Sedimentary Geothermal Systems are different. They start with the same three characteristics as hydrothermal; heat, in-situ water, and naturally occuring permeability. Emulating hydrothermal systems, stimulating convective flows in these formations recharges production zones for sustainable economics.

There’s been a major technological breakthrough in geothermal power at Johns Hopkins University.

Emerging from Johns Hopkins Tech Ventures, Geothermal Technologies Inc, GTI, has developed a technology to emulate natural hydrothermal systems in novel terrain, sedimentary basins. Their GenaSys™ systems produce firm, dispatchable, emission-free electricity, and sustain thermal longevity for decades of economical power production.

GenaSys™ harvests heat from existing water 1000s of meters deep in Hot Sedimentary Aquifers, or simply HSAs. They are a globally abundant renewable resource, common where oil and gas are found, so they can be located, characterized, and simulated with petroleum industry data from a century of exploring these same geologic formations.

With GTI's growing portfolio of patents, GenaSys™ systems are ideal for direct use as well as integrating with other thermal technologies, firming intermittents, and colocating with oil & gas to electrify operations. Working with Colorado's Energy & Carbon Management Commission, GTI was recently awarded the state’s first ever permits for deep geothermal.

Surface Technologies

ORC

Organic Rankine Cycle systems are clean, compact, and efficiently harvest the low and medium-temperature heat provided by GenaSys™ systems.

ORCAT

ORC Advanced Tandem technology enables ORCs to efficiently utilize resources that exceed the typical thermal range of ORCs, particularly with the higher temps of waste heat recovery.

ReCoGen

Waste Heat Recovery Cogeneration enables emission-free power production utilizing waste heat harvested from gas, coal, nuclear power plants, refineries, and other industrial facilities.

At locations with geothermal resources + recoverable waste heat, combining these technologies significantly increases economics and widens the range of suitable geothermal resources.
