Session background and objectives
In ICEF2016, we developed a global roadmap for commercialization potential of CO2 Utilization (CO2U) technologies through 2030, which analyzed the scalability of CO2U in building materials, chemical intermediates, fuels, and polymers in ways that sequester CO2 for long periods.
In this session, we will discuss a means of paring down an extremely large problem space and illustrating the key challenges with looking at case studies of CO2U, and will explore emerging cross-cutting issues (e.g. LCA), identify possible actions that can address these issues, and their impacts. We will deal with mineralization for building aggregates and fillers, chemical feedstocks, and carbon composite materials in the case studies based on the technological maturity, product value, and mitigation potential.

Technical and market challenges for CO2 utilization as a climate mitigation pathway
Conversion of CO2 to useful products has rapidly gained interest as a potential pathway to reduce greenhouse gas emissions. It faces several important technical hurdles, because most conversion pathways require low-cost, low-carbon energy to succeed. In addition, most pathways create products with low volumes or with short CO2 retention times, which limits their viability in climate mitigation. However, the market has begun to differentiate on a basis of carbon footprint, suggesting that some markets may see higher value in a circular carbon economy. In addition to making technical progress (e.g., through new catalysts), important innovations are needed in market infrastructure to enable and validate CO2 reductions for CO2-based products to achieve large market share.

The utilization of CO2 as building block for chemicals or carbon source for fuels has quite different energetic requirements and targets markets of unlike dimension. In a fossil carbon based economy the synthesis of chemicals (intermediates and fine-chemicals) makes sense. For the synthesis of fuels perennial energy sources (sun, wind, hydro, geothermal) must be used as primary energy to be supplied to the process and water as source of hydrogen. The cost of energy and hydrogen produced from the above sources limits the CO2 conversion. The integration of chemical catalysis and biotechnology may push the CO2 conversion to large scale.
