Technology Portfolio
Technology pathways organized by their target product.
The structure focuses on what the process delivers: captured CO₂, clean hydrogen, clean methane or recovered industrial heat. Each category connects directly to a preselected assessment pathway.
ZCT Technology pathway
CCC® for low-partial-pressure industrial flue gas.
Capture technologies differ in selectivity, energy demand, scalability and suitability for dilute industrial gas streams.
Selectively permeable materials separate CO₂ from other gas components. Compact and modular, with no chemical additives, but often limited where very high selectivity is required.
CO₂ is chemically absorbed into an aqueous amine solution and released during thermal regeneration. Industrially established, but associated with significant regeneration energy demand.
Pressure Swing Adsorption uses porous solids under pressure and regenerates them by lowering pressure. It is particularly suited to moderate and high CO₂ concentrations.
Temperature Swing Adsorption uses thermal regeneration of solid adsorbents. It can address dilute flue-gas streams but typically involves longer cycles and higher thermal demand.
Solid chemical sorbents bind CO₂ directly from dilute industrial flue gas and can be combined with downstream catalytic conversion. Capture and value creation are treated as one integrated process pathway.
ZCT Technology pathway
Clean hydrogen from electricity, carriers or industrial waste streams.
Hydrogen production pathways differ in feedstock, carbon intensity, integration requirements and transportability.
Water is split into hydrogen and oxygen using a polymer membrane and electricity. The process responds quickly to variable renewable power but currently requires relatively expensive catalyst materials.
Ammonia can function as a hydrogen carrier and later be cracked back into hydrogen and nitrogen. It simplifies transport but adds an additional energy-intensive conversion step.
Steam Methane Reforming is the established large-scale route from natural gas. Without carbon capture it creates significant emissions and is typically classified as grey hydrogen.
Autothermal Reforming combines oxidation and steam reforming with improved heat integration and produces a concentrated CO₂ stream that can simplify downstream capture.
An emerging integrated pathway that uses chemisorption to recover usable carbon and hydrogen-relevant streams from industrial flue gas while simultaneously addressing emissions.
ZCT Technology pathway
Clean methane through biological, catalytic and integrated conversion routes.
Methane pathways combine biological conversion, catalytic synthesis and integrated waste-gas valorization.
Hydrogen and CO₂ react in a catalytic Sabatier process to form synthetic methane and water. The route is compact but depends on a reliable low-carbon hydrogen supply.
Anaerobic fermentation converts organic waste into biogas, which is upgraded to methane. It is mature and suited to biological feedstocks, but requires additional purification.
Reverse Steam Methane Reforming converts hydrogen and CO₂ back into methane and steam using adapted reformer concepts and catalysts.
Reverse Autothermal Reforming applies controlled heat integration to methane synthesis and builds on the thermal-management principles of conventional ATR.
CO₂ is captured directly from dilute industrial flue gas and coupled with hydrogenation to produce methane in an integrated waste-gas-valorization process.
ZCT Technology pathway
Unlock the full efficiency potential of your industrial heat pump systems.
HP-HRS combines staged flue-gas cooling with heat-pump integration. All performance values are preliminary and remain editable pending technical validation.
Characterize the exhaust temperature, composition, mass or volume flow and annual operating profile.
Recover directly usable sensible heat before the heat-pump stage.
Integrate the evaporator into the flue-gas path to enable deeper heat recovery.
Raise the recovered heat to the temperature level required by the receiving process.
We analyze existing operating conditions, identify efficiency losses and implement process improvements that increase seasonal performance while reducing electricity consumption.
