Why Capturing CO2 from Air (1)

1. Capture CO2 from air

2. Produce hydrogen with renewable electricity

3. Combine hydrogen and CO2 to form hydrocarbon fuel (gasoline, kerosene, methane)

4. Use CO2-neutral fuel in existing energy infrastructure and re-capture CO2

Why Capturing CO2 from Air (2)

Paris Climate Convention Calls for Negative Emissions

87% of IPCC modeling scenarios consistent with 2 °C of global warming involve large scale deployments of CO2 removal from air.

Climeworks Solution • Industrial CO2 capture plants extracting CO2

out of ambient air

• Modular design enabling mass production

• 90% of total energy demand supplied by low-grade heat (solar/geothermal/waste)

• Minimal carbon footprint: only 2-3% side emissions (CO2-eq)

• Worldwide first company supplying atmospheric CO2 to customer

CO2 Release

CO2-free air

Pure CO2

Heat at 100°C

Air is driven through system, CO2 is boundchemically to filter material.

System’s pressure is reduced, heating to 100°C; release of concentrated CO2.

Cooling to ambient temperature, CO2 capture is re-started.

Commercial plants contain parallel modules for continuous CO2 delivery
