Engineering solutions and leading-edge technologies for the global energy transition needs

A renewable energy strategy and capabilities in biofuels, green chemicals and circular economy, carbon capture and storage, and marine energies.

Pyrolysis bio-oil technology

Carbon Capture and Storage

Hummingbird technology


We anticipate our clients’ requirements, commitments and expectations, fostering technologies and engineering solutions that meet future energy scenarios and that promote circular economy.


In the biofuels market, we were chosen by Neste to engineer and deliver two plants intended to mark a major milestone in the Finnish company’s strategy to become the leader in the renewable diesel market.

Green chemicals & circular economy technologies

We are very active in the emerging field of green chemicals and technologies for circular economy. In addition to our proprietary technologies in that sector, we have entered several relationships to develop drop-in or new green chemicals composed, in whole or in significant part, of bio-derived products.

Carbon capture and storage

We have built more than 50 installations for the removal of carbon dioxide and sulfur components from natural gases. This experience makes our company particularly well-positioned to successfully execute all types of CCS projects.

Marine energies

We bring our expertise and skills in the engineering and management of complex projects in marine environment. We are actively involved in the development of Ocean Thermal Energy Conversion (OTEC) technology.
