ICEF develops roadmaps on how key innovative technologies can contribute to a transition to clean energy. Roadmaps consider industrial, academic and governmental perspectives to identify a realistic, fact-based pathway and meaningfully inform the work of all stakeholders.

ICEF roadmaps are collaborative documents developed from the concurrent sessions in our annual conference and refined by reviews and suggestions from specialists.

Innovation for Cool Earth Forum (ICEF) publishes innovation roadmaps for carbon dioxide utilization and energy storage and other technologies with the potential to contribute significantly to long-term Net Zero Emissions.

Direct Air Capture of Carbon Dioxide
Roadmap (Draft)


The IPCC(*) and many scholars agree that achieving a 2 degree C climate stabilization target will be extremely challenging through mitigation efforts alone and will likely require removal of CO2 from the atmosphere at the scale of many gigatons. This number is daunting, but many approaches have been proposed for Negative Emission Technologies (NETs), including land-use techniques, re- and afforestation, bioenergy with carbon capture and sequestration and direct air capture (DAC). The technological status of DAC is very early-stage, with no significant dedicated research, development and deployment (RD&D) programs and only a handful of pilot-scale facilities currently operating.

Focus Areas

This roadmap will explore the portfolio of NETs in under 2 degree C scenarios, DAC technologies and their status, long-term goals for DAC (e.g. economic viability, ensuring net CO2 removal from the use of DAC and CO2 utilization, role of renewable electricity, RD&D targets) and policy support.


ICEF2017 Roadmaps: CO2 Utilization 2.0 and Energy Storage

ICEF2017 Roadmaps:
CO2 Utilization 2.0 and Energy Storage

CO2 Utilization Roadmap
CO2 Utilization 2.0 Roadmap

This roadmap builds on ICEF’s previous work to fill the gap on the viability of the potentially high-impact CO2U technology, stressing the need for life-cycle analysis and exploring effective policies to promote CO2U.
It focuses on concrete & carbonate materials (near-term market), commodity chemicals (near- and medium- term market) and durable carbon materials (small market today but potential large long-term market).

Energy Storage Roadmap
Energy Storage Roadmap

This study examines the current statuses and timelines of three potentially attractive areas of energy storage that can have a high impact on energy system transformation.
These are: stationary electric energy storage to ensure power system flexibility, mobility electric energy storage as key to the transportation electrification, and stationary thermal energy storage storing renewable or environmental heat.


ICEF2016 Roadmaps: CO2 Utilization and ZEB/ZEH

ICEF2016 Roadmaps:
CO2 Utilization and ZEB/ZEH

CO2 Utilization Roadmap
CO2 Utilization Roadmap

A recent study found carbon dioxide utilization (CO2U) technologies have the potential to reduce global carbon emissions over 10% by 2030. This study presents a roadmap for the commercialization of carbon dioxide CO2U technologies through 2030 by assessing almost 180 global technology developers.

ZEB/ZEH Roadmap
Net Zero Energy Building/
Net Zero Energy House (ZEB/ZEH) Roadmap

This presents a ZEB/ZEH roadmap for different climate zones taking into account the neglected factor of humidity in air conditioning, especially in humid areas in Asia where energy demand is set to increase substantially. Four technology categories are proposed with timescales: passive (building envelope), active (equipment), renewable energy integration and energy management.
