Emission Reductions from Battery- Powered Geotechnical Drilling

Project: Emission Modeling in Collaboration with Terravera‍
‍Unit: Head Energy Geo

Head Energy Geo has implemented battery-powered hybrid drill rigs for geotechnical site investigations. This enables operations to be carried out without the use of diesel generators, resulting in reduced greenhouse gas emissions and improved environmental performance, particularly in urban and regulated project areas.

To quantify the impact, Head Energy Geo has worked with Terravera to develop a model that estimates the CO₂ emissions avoided by using the battery-powered hybrid solution instead of conventional diesel-only rigs. Using input such as estimated project hours, the model calculates both the emissions associated with a conventional setup and the emissions from the hybrid alternative.

A Python script developed in the project automatically calculates:

• Emissions avoided by choosing the hybrid rig
• Emissions that would have occurred with a diesel-based operation

These charts are especially valuable in tender documentation, helping clients see the environmental benefits of selecting Head Energy Geo as a supplier. The tool is available via the Terralight portal, and further training is planned to ensure Head Energy Geo can use both the platform and script independently in future bids.

The collaboration has also opened the door for further exploration of emissions across various project and construction phases. As new regulations – such as the revised EU Energy Performance of Buildings Directive – come into force, the ability to document and reduce environmental impact will become even more critical.
