About us

We founded Hephae Energy Technology to push the temperature limits of electronics and sensor technologies to allow the exploitation of geothermal energy in hot, dry rocks.

Our team brings more than 100 years’ experience developing and running technologies in some of the harshest drilling conditions in the world. Our first task will be to develop an innovative integrated drilling system that enables geothermal to become the go-to source of clean power anywhere on the planet. 

Hephae Energy Technology timeline:

Hotter is better!

Hotter is better for geothermal power generation. We’ll leverage the lessons learned in geothermal drilling to date while importing directional drilling expertise and technologies perfected by the oil and gas and aerospace industries. We will start by creating a directional drilling system that will work up to 225 Celsius but ultimately we’re aiming for 300 Celsius-rated tools. Once we have perfected directional drilling and measurement, we will have all the tools we need in terms of sensors and electronics to develop a wide range of products to help drill, complete and monitor geothermal wells. 

Faster, more precise drilling and measurement with lower failure rates and new capabilities will drive down geothermal development costs. We can have a green drilling boom, but first the world needs the tools to make that happen. We are the team to create those tools. We are currently pre-seed and looking for initial funding to turn our vision into reality.

Our commitments to sustainability, diversity, equity, and inclusion

We founded Hephae because we saw the need for plentiful, clean, and reliable energy for the planet through the 21st Century and beyond. We realised that geothermal energy would be a very important part of any solution. We are committed to enabling the development of a new unconventional geothermal industry to provide that energy.

The cost of drilling and completing geothermal wells will be key to the economics and therefore the uptake of this new industry. We are committed to minimising the cost of the technology we will provide. In addition to helping to drive economics, we are also mindful that cost of equipment and spares is directly attributable to the resources consumed in their manufacture. Therefore, by minimising the cost of what we produce we will also be minimising its resource footprint.

Diversity of background creates diversity of perspective and thought. Innovation is driven by diversity, and diverse teams are a very powerful thing. We are trying to do things that have never been done, and it’s our intention to employ people who have not previously worked on downhole tools and who do not know that “it can’t be done”. Teams who don’t realise that things cannot work will make those same things work. We are strongly committed to recruiting a diverse team across our multiple locations.
