CO2 capture from the air: myth or reality?
Technology wise, a reality
Carbon dioxide can be removed from ambient air through chemical processes based
on acid-base reactions. Direct Air Capture (DAC) is comparable to the respiratory
system or the photosynthesis.

Why capture from the air when there are so many
concentrated CO2 sources?
Advantages
DAC can capture the CO2 emitted by decentralized
sources (e.g. transport)
It can be decentralized towards sites that offer a
cheap source of renewable electricity and heat
Deployed closed to CO2 storage sites, DAC becomes a
Negative Emission Technology (NET)
Its modular construction means many of them can be
built which can drive down cost
Direct Air Capture for a circular carbon economy
Challenges
CO2 in the atmosphere is highly
diluted (~400 ppm):
Large energy footprint
Cost
Large land footprint
These challenges can be
overcome by:
Contactor development
Low carbon energy, such as
waste heat in the case of low
temperature DAC
DAC with storage can be a NET, next to bio-CCS, carbon soiling, reforestation

Its performance is driven by:
• Its composition (nature of the metal, enzyme…)
• Structure / morphology / microstructure
• Type and nature of support
• Immobilization method

A catalyst is specific for each final product, reaction conditions and type of process

Platinum group metal (PGM) catalysts dominate today’s
applications
10
CHALLENGES
Even at high production volumes, the PGM catalyst is expected to represent a significant part of the fuel cell cost.
The wide development of electrochemical processes, that bridge the molecule-based economy with a green electricity
production should avoid the intensive use of PGM materials. As such, a large scientific effort is devoted to the development of low-
PGM and PGM-free catalysts.
Developments of new catalytic materials with improved performance are focused on composition and microstructure.

Demonstration
Future catalyst will have to be based on earth-abundant
materials and will require to work at moderate pressure
and temperature ultimately
The biocatalytic approach could allow the convergence of both approaches
ADVANTAGES
Mimicking the reactions taking place in
living organisms, biocatalysis has many
attractive features in the context of
green and sustainable chemistry:
Mild reaction conditions: ambient
temperature and pressure
High flexibility
Efficient
Highly selective
Sustainable : biodegradable catalyst
(enzyme)
CHALLENGES
Recycling biocatalysts
Development of more stable
biocatalysts according to two different
approaches:
- Keep wild type organisms / enzymes and
select organisms that live
in extreme environments as these will
be naturally more stable.
- Engineer it using genetic tools

Commonly used microorganisms are hydrogenotrophs like Cupravidius necator, Rhodococcus opacus or Hydrogenobacter
thermophiles. These bacteria oxidize hydrogen in anaerobic conditions to power their metabolism and accumulate proteic
biomass at high rates (kg/m³.h scale)
Power-to-protein concept for food/feed production: a process that decompartmentalize energy, biology and agriculture sectors.
Power-to-proteins approach consists in the production of a
protein-rich material by bacterial cultures using electrolytic

Similarities with the
informatics wave?
Actors in the field sometimes compare this
evolution to the computer and IT revolution
that occurred the past decades as both show
impressive growth and several similar
concepts
The steadily growing biotech economy is experiencing
an ever growing momentum pulled by key enabling
technologies to harness biology without wasting resources
17
Biotechnologies have been ever rising since a couple of decades through 3 main different
sectors: industrial, pharmaceutical and agricultural applications.
Stronger development is observed due to several factors:
Dropping DNA sequencing costs to access massive information
Artificial intelligence (especially machine learning) developments to manage the
massive amount of data
CRISPR/Cas9 development, a genetic editing tool to screen large number of precisely
edited mutants
Laboratory increasing automatization capacity
“Blank” chassis “Evolutionary” based
chassis
Constructed by modules (parts)
Behavior code based
Non self replicative Self coding and self

Possible contamination by external code
Similarities with IT exists but fundamental differences

3 pathways towards Carbon neutrality
• Increase energy efficiency and increase circularity where waste becomes a feedstock
• Electrify as much as possible (far beyond electric cars)
• The need for molecules: (green) hydrogen and synthetic hydrocarbons

February 2021
More than half of the emission reduction will have to come from technologies that are
today not mature: Innovation and R&D are crucial and need to speed up!
Fatih Birol, IEA September 2020: ‘CCUS, Batteries and H2 are today where PV was 10 years ago.
GOVERNMENT need to support their development now!’

3 pathways towards
Carbon neutrality

(i) Increase energy efficiency and increase
circularity where waste becomes a feedstock

A renewable fuel to
generate heat (hot water
or steam) and electricity
(CHP) on site
Biogas is purified to be injected into the gas grid for
industrial and domestic uses, such as heating or
cooking
Biogas
Digestate
Is used as natural fertilizer
Organic waste goes
through an anaerobic
fermentation process
which produces
digestate and biogas.
2. Anaerobic Digestion
Organic waste are collected and
transported to the methanization site
1. Collection
3. Upgrade
4. end-uses
Biomethane is
considered carbon-
neutral
CO2 from the atmosphere is
captured by organic waste used
to produce biomethane
Its combustion produces
biogenic C02 emissions
Compensation effect: almost
no impact on greenhouse gas
emissions.

(ii) Electrify as much as possible (far beyond
electric cars)

January 2021
Making sure all our electricity generation is green is crucial but is not sufficient as it
will only reduce our overall emissions by 38 %.
Industry, transport and building account for half of emissions today! (IEA, ETP 2020)

January 2021
We must not only build new clean aluminum, cement, iron and steel, chemical, … plants BUT
must address emissions from EXISTING infrastructure since many assets are still young!
CCUS and H2 will be required.

January 2021
Belgian’s federal planning bureau estimated that even in the deep electrification scenario
(electrify as much as possible also in industry), molecules and import of renewable Energy
remain important
88
(2018)
Import of renewable
energy remains
important and both
scenarios do not
diverge
(much) in terms of their
annual net import
position in 2050: 29.4
TWh in ‘Diversified
Energy Supply’ and 29.0
TWh in ‘Deep
Electrification’

electric cars)
(iii) The need for molecules: (green) hydrogen and
synthetic hydrocarbons

February 2021
• Energy efficiency and circular economy are first crucial steps towards carbon neutrality
• Electrification using renewable electricity of many processes (beyond electrical vehicles) is a good idea!
• Hydrogen is difficult to store and move → where possible, direct and local use
• Turning hydrogen into another molecule (e.g. synthetic hydrocarbon like methane, methanol, …) makes
transporting its energy possible and we have existing infrastructure to do so!
• CCU makes sense:
• So carbon will play an important role in the carbon neutral energy transition!

At european level…
The EU Green Deal
◼ Carbon neutrality by 2050
◼ - 55% CO2 by 2030

CCUS forecasts
◼ CCUS = Carbon Capture, Utilization and Storage
7
IEA, 2020. https://www.iea.org/reports/energy-technology-perspectives-2020

CO2 capture
◼ It’s a question of fluid separation!
❑ Sources usually contain CO2, N2, H2O, H2, CH4, O2 …
❑ CO2 concentration varies between 0.04% and almost 100%
❑ Mature (exist for >50 years) & flexible, but cost only!
9

CO2 separation technologies
◼ Avoid fluid mixtures
◼ Absorption
❑ Physical
❑ Chemical
◼ Adsorption
◼ Membranes
◼ Cryogenic separation
◼ Others…
Threshold value ~15 vol-% in flue gas,
or 4 bar of P_CO2

CO2 capture thermodynamics
◼ Thermodynamic study on energy costs and penalties

Direct Air Capture (DAC)
◼ Negative CO2 emissions
❑ BECCS or DAC
K.S. Lackner, CNCE ASU, 2017.
16

Direct Air Capture
◼ Motivations
❑ Address non-concentrated CO2 emissions
❑ Close the carbon cycle of synthetic fuels
❑ Reduce the need for transporting CO2
◼ No Nimby effect, you can go wherever you want, incl.
close to use or storage sites
❑ Long-term considerations: remove C from the atmosphere
❑ Cost mostly due to sorbent regeneration, not from air
contacting
❑ Sorbent regeneration has similar cost whatever the CO2
concentration in the gas stream

DOI: 10.1140/epjst/e2009-01150-3 17

Direct air capture
◼ ~ 410 ppm in the air
❑ Adsorption / Absorption
❑ Temperature-swing, moisture-swing
❑ Expected costs vary between 100 and 800 $/ton
Wang et al, Environ. Sci. Technol., 45, 6670–6675, 2011
engineering.asu.edu/cnce 18

Cost of CO2 capture
◼ Estimated cost for different industries
❑ Opex ~75% of the cost

◼ European Emissions Trading System (ETS)
◼ CO2 price now reaches > 30 €/t!

3. Storage and/or re-use of CO2 ?

Storage is state-of-the-art
◼ Potential for storage exceeds by far the needs
❑ 5000 – 25 000 GtCO2 vs. ~ 2000 GtCO2
❑ Pure storage: ~ 5 Mtpa
❑ Capture and EOR: ~ 30 Mtpa in 2016
◼ Storage costs ~7-30 USD/t, large infrastructure costs needed!
22
Global CCS Institute 2017
doi: 10.3389/fclim.2019.00009

Northern lights
◼ Norway, off-shore field, saline aquifer
◼ Up to 5 Mt CO2/y
https://northernlightsccs.eu/en
23

Porthos
◼ Rotterdam, off-shore depleted gas field
◼ 2.5 Mt CO2/y
24

Antwerp@C
◼ No storage capacity offshore of Belgium
❑ Antwerp@C studies the infrastructure for connection to Norway
and The Netherlands
❑ => Pipelines, intermediate storage, liquefaction unit…
25

CO2, waste or feedstock?
◼ Sequestration or re-use?
❑ Consider CO2 as a resource, not as waste
◼ CO2 re-use potential up to ~ 4 – 16 Gtpa
◼ So far, sources for CO2 are high-purity ones
❑ Industrial (Ethanol, Ammonia, Ethylene, Natural gas…)
❑ Natural (Dome)

4. Conclusions and perspectives

State of technology CCUS
◼ Capture of CO2
❑ Mature but limited application yet
◼ Storage
❑ Commercially applied (mostly EOR)
◼ Re-use
❑ Maturity depends on technology, from TRL 1 to 9
◼ Big acceleration due to Paris COP21 agreement and environmental
urgency
❑ European Green Deal
