Geothermal isn’t theory — it’s already powering major organisations. From airports to health systems, we design and deliver underground energy plants that cut emissions, reduce costs, and keep operations resilient. Explore how different clients solved complex energy challenges with permanent, low-risk infrastructure.
Is your site ready for geothermal?Cavan General Hospital
Hybrid geothermal system delivering 600 kW for resilient, low-carbon energy at Cavan General Hospital.
AMS
A platform that adapts as they do: AMS solved data challenges fast and gained long-term efficiency.
PPG Shannon
As PPG Shannon scaled, they needed more than static reports—live insight kept teams aligned and performance on track.
Dublin Airport Authority
Faced with complex systems and bold targets, DAA used scenario planning and lifecycle analysis to map the smartest path forward.
Cavan General Hospital
The expansion of the Cavan General Hospital site includes a new 68,000 m² Emergency Department building, placing major demands on energy for heating and cooling. Relying on conventional systems would risk higher costs, dependence on fossil fuels, and limited resilience.
The solution
A hybrid geothermal energy system designed to meet the hospital’s long-term needs. At its core is a GeoBattery capable of delivering 600 kW of heating and cooling, addressing the majority of the building’s demand. To ensure resilience and flexibility, the system integrates a groundwater-based water-to-water solution that provides additional capacity.

Data that moves
with the business
In a sector as energy-intensive as aluminium extrusion, AMS needed more than static reports—they needed live, reliable insight. With OPN, they built a structured system that brings clarity across energy, process and emissions data. Legacy gaps were replaced with high-integrity metering, ISO-aligned tracking, and scenario planning. Solar and water systems are now monitored continuously—keeping AMS accountable and on track toward net-zero.

TURNING COMPLEXITY INTO CLARITY
Live insight for a site
that never stands still
At PPG Shannon, nothing stays still—equipment changes, loads shift, and teams work in parallel. PPG needed a system that could grow with them. With OPN, they replaced outdated monitoring with live, validated data, expanded metering as the site scaled, and gave teams the visibility to take ownership. ISO 50001-aligned practices became part of daily routines, and clearer insight allowed them to refine targets and track real progress.

Data that drives
accountability
Tyndall needed more than data—they needed visibility. By building a long-term monitoring system and tracking seven performance indicators, they moved from reactive management to proactive decision-making. This shift enabled deep emissions cuts and long-term efficiency—proving that the right tools make real progress possible.
