CAPTUS

Demonstrating energy intensive industry-integrated solutions to produce liquid renewable energy carriers from CAPTUred carbon emissionS

CAPTUS will demonstrate sustainable and cost-effective pathways to produce high-added value Renewable Energy Carriers (RECs) in Energy Intensive Industries (EIIs) by valorizing industrial carbon emissions and integrating renewable electricity surplus.

Three complete REC value chains will be demonstrated at 3 different demonstration sites:

1. A bioprocess based on a two-stage fermentation to produce triglycerides in a steel plant.
2. Lipids-rich microalgae cultivation followed by hydrothermal liquefaction to produce bio-oils in a chemical plant.
3. Electrochemical reduction of CO2 to produce formic acid in a cement plant.

DRAXIS will identify and comprise a list of Key Performance Indicators (KPIs) to describe the system’s performance from a sustainability point of view (i.e., comprising environmental, economic and social aspects).

In addition, DRAXIS will provide an integrated Life Cycle Assessment (LCA) for the triplet of the developed solutions. This refers to assessing the sustainability of the novel technologies, in terms of environmental, economic and social performances, taking into consideration their entire life cycle
