Problems we solve at your plant

Field measurements, modelling and economic analysis to inform industrial decisions. The examples come from the team’s project experience.

Transition to sustainable fuels

We assess fuel compatibility, flame stability, effects on the product and the cost of the change.

Examples: Green H₂ in CSN galvanizing; biomethane at Stellantis; decarbonization routes for glass furnaces.
