Causeway Energies works across a range of sectors that all have large demands for heat. We offer Consult to assess and provide the preliminary designs for low/zero carbon energy systems.  Design and Build takes that concept to final design and installation.  Heat-as-a-Service is our novel approach to financing the upfront capital costs of the new energy system.  We work across a number of industries to consult, design and implement geothermal and complementary solutions.

The process starts with a conversation: we get to understand your needs a little better, and you get the chance to ask questions about our services, team and technology.

Our Technology

Causeway Energies’ technological approach to renewable geothermal energy and decarbonising heat is distinctive and disruptive. Decarbonising heat is a major challenge in the energy transition. For example, industrial and commercial processes that use temperatures less than 200˚C emit more than 20% of the world’s greenhouse gases. Causeway Energies is focused on this sector using geothermal energy and storage, heat pumps and energy efficiency innovations, integrated with out renewable energy sources.  Our systems are zero or low carbon and are cost competitive with fossil fuel predecessors.

Our key sectors

Causeway Energies is at its heart, an energy service company. Our mission is to provide our customers clean, affordable and reliable heating and cooling. Geothermal energy is the technological core of our approach. We focus on four core industries with an emphasis on providing heating and cooling for large scale and industry settings. Click below to learn about specific industry applications, our process, and funding models.

Places: large buildings, neighborhoods, cities

Data centres, business parks, offices, neighborhoods all need heating and cooling 24/7, 365 days a year. Geothermal is the energy lynch pin of the production, storage and recycling of renewable heating and cooling within Microgrids and District Heating Networks.

Agriculture, Food & Beverage

Heating and cooling is fundamental to the growth and production of food. Our low footprint geothermal solutions are ideal for many heating and cooling needs from greenhouses, making beer or whiskey, pasteurisation and soil warming.

Pharmaceutical Manufacturing

Ireland & the UK are home to many multinational pharmaceutical companies that have intense energy needs for heating & cooling. Our solutions are primed to meet many of these demands in both an environmentally & cost sustainable way.

Water & Natural Resources

Local geothermal energy can be used to decarbonise water recycling, biogas production, and mineral ore processing. Water utilities are a source of waste heat to be recycled and abandoned mines and oil/gas fields can be refurbished as energy sources and stores.

Who We Are

There is a renewable energy source that is available all day, every day, whatever the weather. It comes from the earth beneath us. Geothermal energy is the largest source of clean energy on earth.

We’re Causeway Energies.

Born on the island of Ireland, we are a renewable energy company on a mission to harness critical, clean geothermal energy, everywhere.

We do this by developing cutting-edge technology, working in balance with nature to provide locally sourced, clean, 24-7 heat for industrial and commercial customers.

We are a team of experts who work relentlessly to secure a sustainable future.

We are united by our shared values of Pioneering Spirit, Considerate Soul and Ethical Impact.

Geothermal energy – constant, clean and limitless – accelerating the energy transition.

Sustainable Impact

At Causeway Energies we are committed to playing our part in the United Nations’ Sustainable Development Goals. Our technology can significantly reduce greenhouse gas emissions and be deployed locally, increasing energy accessibility and affordability. We are an international technology-driven geothermal operating company that supports research and development in geothermal energy and decarbonisation of heat.
