Our Mission

Advance Geothermal


GEAA is a stakeholder driven Association that advocates increased investment in geothermal energy and increased awareness of this sustainable source for near zero-carbon power, heat and hot water.


The Association is a not-for-profit organisation offering leadership and a dialogue in the energy transition debate. It is open to all those interested in advancing geothermal energy and its role in transitioning to a world using less petroleum.


Geothermal energy is a constant energy source that is present everywhere occurring naturally underground - both onshore and below the sea-bed. It can be accessed through the use of wells, providing a reliable, year round 24/7, emissions and pollution-free base-load for power generation and heating, both for on-grid and off-grid projects.


Integration of geothermal solutions to provide low emission heating and power can significantly reduce global carbon footprints and accelerate Net Zero ambitions.


Geothermal projects can often utilise existing petroleum industry infrastructure, technology and wells whilst applying the subsurface skills and innovation of geoscientists and engineers.


Geothermal energy can be used for a stable supply not subject to weather conditions, does not involve significant carbon emissions or pollution, does not consume large amounts of rare minerals, and often can be configured as financially standalone projects.


The Association promotes awareness and consideration of geothermal energy as an energy and heat source, and policy and legal frameworks to accelerate the use of geothermal energy. With increased investment, and a wider understanding of how geothermal energy can be used, it can become a key part of a clean energy future used in all countries and communities. 

" Failure to Act is an Act of Failure"


Achieving Net Zero

It's time to face the facts:

Deep geothermal is  the only 24/7 true baseload green energy, which will play a key role in the energy transition to achieve global net zero targets

 A Sustainable Future with Geothermal Energy


“Sustainable, secure and affordable energy for both the developed and developing world is a key target for the UN’s Sustainable Development Goals.


Delivery of such a goal is tough and yet there is one energy sector - geothermal - that delivers big time in terms of its sustainability and security and yet is little developed the world over.


Sustainable - humans just don’t have the power to cool the Earth. Secure - every nation on Earth has the natural resource of geothermal energy underground.

Low impact - development of geothermal energy demands no exotic minerals and has ultra-low emissions of GHGs and can deliver 24/7, great base load.


Today development costs can be high but with the skills, innovation and know how assembled in the GEAA we will deliver on affordability too.”

The challenges we face


“The challenge of climate change will dominate the world we live in for decades. Overcoming this whilst building a lower carbon world and maintaining economic growth represents a challenge never faced before.   With a rapidly growing global population, the challenges include providing more clean heat and power, as well as reduced emissions and pollution.


Many solutions are needed to create energy security for future generations. Geothermal can play a leading role in a cleaner, decarbonised world, embracing ESG whilst creating quality jobs.


The Association seeks to make all governments, institutions, companies, businesses & individuals fully aware of the benefits and role of geothermal in an energy transition.

The Sector Working Groups are a driving force for tackling the challenges. We therefore encourage you to become an active GEAA member.”

Geothermal energy comes in many forms,
and can have many uses

Getting There


Often viewed as the "Star" prize, MWe can be one of the outputs

under the right conditions and contribute to on or off grid.


The most efficient form of Heat for District Heating Networks and Cooling is achieved via direct heat from Geothermal


The potential of Geothermal Energy is not limited to Power and Heat, it extends across a cascade of other outputs including Hydrogen, Desalination, Agri & Aqua Culture.
