Emerging sustainable technologies 2025 : "Defossilisation of the industry"


ENGIE Research & Innovation publishes an inspiring annual report on emerging sustainable technologies to accelerate the energy transition. This year, we are offering a special edition dedicated to solutions for defossilising the industry.

Our greatest ambition is to inspire everyone to be part of this transition. As this report shows,  we will not be able to blame the lack of sustainable technologies for failing to achieve our climate ambitions!

Interview : "Defossilisation of industry: We won’t be able to blame technology!"

Of the nearly 50 gigatons of greenhouse gases emitted annually by human activities, almost one-third is related to energy use in industrial processes and process emissions in industry. In the International Energy Agency’s (IEA) Net Zero Emission Scenario (NZE), a significant reduction of these industrial emissions occurs later than the large emission reductions predicted in the transport or building sectors.

Decarbonizing Steel Production

The conventional method of producing steel—by reducing iron oxide with coal or natural gas—is one of the most carbon-intensive industrial processes in the world. Pilots are launched to find innovatives solutions for fossil-free steel by using hydrogen or electrolytic process.

Revolutionizing Cement With Microwave Technology

For every ton of cement produced, approximately 900 kg of CO2 is emitted. With global production exceeding 3.5 billion tons annually, and demand rising—especially in emerging economies—decarbonizing cement is a critical climate challenge. One promising solution? Microwave-assisted processing of raw materials.
