ICEF2016 Roadmaps: CO2 Utilization and ZEB/ZEH roadmaps released at COP22

Posted by ICEF Secretariat December 7, 2016

ICEF develops roadmaps on global industry-academia-government initiatives for sharing visions and facilitating discussions for the development and dissemination of innovative low carbon technologies. After reflecting the discussions in concurrent sessions in the 3rd annual meeting and review comments and suggestions from experts, the two roadmaps on CO2 Utilization and ZEB/ZEH were released at the launch event held in COP22, Marrakech, Morocco.

CO2 Utilization Roadmap

Background: Confronting an urgent challenge

This study presents a roadmap for commercialization potential of carbon dioxide utilization (CO2U) technologies through 2030. CO2U technologies can play an important role to achieve the agreed global goal of keeping temperature increases well below a 2°C increase over pre-industrial level, but have not yet received much attention nor have their potential been explored in a comprehensive fashion.

A detailed market assessment study that was completed earlier in 2016 found that CO2U has the potential to reduce global carbon emissions over 10% by 2030. One goal of this work is to create greater awareness concerning the potential for developing and deploying profitable, emissions-negative CO2U technologies on a mass scale.

The study: Identifying and forecasting market opportunity

This study analyzes the current state of CO2U technology, assessing almost 180 global technology developers on the basis of their technology feasibility, readiness, markets and momentum. Research revealed that significant progress in CO2U has been made in the past five years (2011-16), with many technologies shown to be scalable. Momentum is favorable for four major markets – building materials, chemical intermediates, fuels and polymers.

Within those markets, the study further identifies eight product categories to pursue, based on the maturity of their technology, market promise, and potential impact on the mitigation of carbon emissions. Those categories are:

  • Building materials
    • Concrete
    • Carbonate aggregates
  • Chemical Intermediates
    • Methanol
    • Formic acid
    • Syngas
  • Fuels
    • Liquid fuels
    • Methane
  • Polymers
    • Polyols and polycarbonates

ZEB/ZEH Roadmap


Buildings sector accounts for 31 % of final energy demand in 2013, while it will account for 40% in 2050 under IEA ETP2016 (*) 6DS. A deep CO2 cut is required to achieve the 2-degree Celsius temperature rise target adopted in the Paris agreement. Technologies and institutions are investigated to realize the net zero energy ZEB/ZEH (*) concept and summarized as a roadmap.

Roadmap overview

Humidity is a key factor in indoor comfort as well as temperature. It is crucial to properly control humidity in moderate and humid regions such as Asia where substantial energy demand increase is expected in the future. However, most existing roadmaps have paid little attention to humidity in air conditioning. Hence, we have proposed several roadmaps by climate zone including roadmaps with humidity.

In the roadmaps, four technology categories are proposed. They are passive (building envelope), active (equipment), renewable energy integration and energy management. The progress of each technological element is shown in the timelines with the expected available period in the market. In addition, differences in building vintage (new/retrofit), technology maturity and climate zone etc. are represented in roadmaps.


Three proposals below are made to utilize the roadmap.

(1) Sharing net zero energy building as a concept in society.
(2) Immediate action through stakeholder (national government, local government and private sectors) involvement, considering building lifetime and stakeholder diversity.
(3) International technology collaboration and diffusion policy promotion via roadmap sharing.

ZEB/ZEH Roadmap has been updated. (March 2017)
