Achieving global climate targets necessitates aggressive industrial decarbonization strategies, particularly within hard-to-abate sectors like steel, cement, and chemicals. These industries, foundational to modern economies, are significant contributors to global greenhouse gas (GHG) emissions, primarily from process emissions and energy consumption. Effective decarbonization demands a comprehensive, multi-pronged approach addressing both operational efficiency and fundamental process transformation.
Key Strategic Pillars
Several interconnected strategies underpin effective industrial decarbonization:
- Energy Efficiency & Electrification: Optimizing energy use through advanced process controls, waste heat recovery, and insulation is foundational. Where feasible, switching from fossil fuel-fired processes to electric alternatives powered by renewable energy offers significant emissions reductions.
- Fuel Switching: Transitioning from conventional fossil fuels to low-carbon alternatives such as green hydrogen, sustainable biomass, and advanced biofuels is paramount. This requires significant investment in production infrastructure and supply chains, alongside robust certification mechanisms.
- Carbon Capture, Utilization, and Storage (CCUS): For unavoidable process emissions or where alternative fuels are not yet commercially viable, CCUS technologies play a critical role. This involves capturing CO2 from industrial flue gases and either utilizing it (e.g., for synthetic fuels) or permanently storing it underground.
- Circular Economy Solutions: Integrating circularity, including material efficiency, industrial symbiosis, and increased recycling rates, reduces demand for virgin materials and associated energy-intensive primary production, thereby lowering embodied emissions.
- Process Innovation: Developing and implementing entirely new, low-carbon production pathways (e.g., direct reduction iron with hydrogen, electrified cracking) represents the long-term solution for many sectors, requiring substantial R&D and pilot project investment.
Our technology is already making a contribution to industrial decarbonization strategies by intensifying processes thereby reducing resource and energy use.
