Hephae Energy Technology, a Houston-based company, has raised $17.8 million in its initial Series A funding round to speed up deployment of its ultra-high-temperature drilling technology for the geothermal energy industry. The investment follows the company's strategy to advance its drilling technology to achieve more access to geothermal resources that are deeper and hotter, putting it on track to construct a drilling rig that can operate at extreme thermal conditions.

The funding is to be channeled at a time when there is an increasing interest in enhanced geothermal systems (EGS) worldwide, since governments and energy companies are looking for more reliable sources of clean energy to supplement renewable energy generation. The new capital will be used to scale its technology and to push research on next generation drilling systems to even higher temperatures, Hephae said.

Hephae Energy Technology was established in 2020 to develop Ultra-High-Temperature (UHT) drilling and measurement systems for geothermal applications. Its solutions are sensor, communication, measurement and control technologies developed to operate outside of the temperature ranges of traditional oil and gas drilling equipment.

Measurement-while-drilling (MWD) systems are typically not effective in high temperature geothermal wells and restrict the ability of the industry to access deeper heat resources. Hephae's technology resolves these issues by offering equipment that will be able to operate at much higher temperatures, enabling operators to collect accurate drilling data where existing technology cannot.

Capital can be provided to accelerate commercial deployment if needed.

The proceeds of the financing will be used primarily to commercialize its Pandora 210 drilling system, the company said. The technology will run at temperatures up to 210°C, which is higher than many of the existing MWD systems in use for geothermal drilling that have an operating limit near 175°C.

The investment will be used to scale the Pandora 210 platform as well as research and development for future drilling technologies that can be used in conditions in excess of 300°C, which are expected to be crucial to unlocking superhot rock resources and enable them to produce much higher amounts of geothermal energy than conventional geothermal reservoirs.

The company is convinced that durability and reliability of drilling equipment in these harsh environments could contribute to minimizing non-productive drilling time, and to overall cost reductions in geothermal electricity production.

The use of advanced geothermal solutions is growing.There is an increasing demand for advanced geothermal solutions.

With the drive towards decarbonising energy systems around the world, geothermal energy is increasingly gaining importance for its ability to deliver low-carbon power without weather dependency. But, in order to reach the deep geothermal resources, it is necessary to use drilling machines that are able to resist high temperature and bad underground environment without affecting the operation efficiency.

Hephae claims technology specifically developed to overcome these challenges by allowing operators to safely approach hotter and deeper geothermal. The company hopes this enhances the reliability of drilling and decreases equipment failures, making advanced geothermal projects more economical.

In addition, the ability of ultra-high-temperature drilling systems to withstand high temperatures is anticipated to help new superhot rock projects, where temperatures are significantly above those in conventional geothermal fields, and may be able to produce more energy from fewer wells.

Steve Krase, Chief Executive Officer of Hephae Energy Technology, said the investment is a significant step to the company's transition from technology development to commercialization.

The funding will help Hephae offer ultra-high-temperature drilling technologies needed for the rapidly growing geothermal industry in the U.S. and worldwide, said Krase.

The company believes its solutions will help the industry be more efficient in drilling and help power the greater transition to geothermal energy projects that can provide reliable low-carbon electricity.

Susquehanna Sustainable Investments and Underground Ventures co-led the Series A funding round. Alfa8, Baruch Future Ventures, Centaurus Capital LP, Elemental Impact, Exa Ventures, Future Ventures, Grantham Foundation for The Protection of the Environment, New System Ventures and True North Institute are among the new investors who are part of the financing.

Investor Nabors Industries was also a participant in the round, continuing to invest in the company's technology development approach. Hephae has raised $24.7 million in total investment to date after the latest investment.

In this regard, Torsten Kolind, Managing Partner at Underground Ventures, said that the geothermal industry is progressing to higher-temperature geothermal resources and Hephae's technologies are progressing to address changing industry technical needs. The company has exciting plans for the future and we are happy to be helping them grow, he added.

The new investment will allow Hephae to increase its commercial deployment of its drilling technologies and further develop systems to operate at ever more extreme geothermal conditions to enable wider geothermal drilling technologies to tap deeper and more efficient sources of renewable energy.
