Biochemical CO 2 capture One more tool for

Biochemical CO 2 capture One more tool for adressing climate change challenges • A sustainable development technology • For energy production and heavy industries • First commercially available biochemical process - No more CO 2 to handle -

Greenhouse gases (GHGs): when « too much » is « bad » • Nature has had GHG emissions for ever – In balance with GHG consumption by natural means • Increasing human activities generate an excess of GHG emissions – Imbalance with GHG consumption by natural means • GHG emissions will have to be reduced – voluntarily and/or by regulation • CO 2 is the most prevalent GHG – followed by CH 4

Many ways to reduce GHGs • GHG reduction achievements will be a combination of various approaches – Selecting the best energy source • coal, oil, natural gas, biogas, hydrogen – Upgrading industrial processes • to reduce amounts of GHGs produced – Capturing CO 2 after being emitted • for massive recycling or sequestration

Capture of CO 2 emissions • Greenhouse gas emissions are gas mixtures – CO 2, CH 4, H 2 S, NOx • The petro-chemical industry already knows how to selectively extract CO 2 from a gas mixture – For industrial use of the CO 2 -free gas mixture – Disposal of CO 2 at lowest cost • GHG volumes are massively higher than CO 2 volumes extracted by industry – Petrochemical industry technologies are cost prohibitive

Capture - Sequestration • First, capture CO 2 – Extraction form a gas mixture – Condensation, liquefaction • Then, sequestrate it – Where ? Environmental risks – Will it come back in the atmosphere as CO 2 ? • Need for new technologies – Less risk, definitive CO 2 elimination

CO 2 Solution Inc. offers an innovative alternative • CO 2 gas is converted into an unharmful liquid by-product, right at point of emission • No more need of energy to compress or liquify captured CO 2 • No more CO 2

Biochemical catalyst Using a potent and robust biochemical catalyst, CO 2 Solution’s treatment unit replicates a natural process occuring in human muscles - Carbonic anhydrase One of the most efficient catalysts, now available for industrial use Massive amounts of catalyst are affordably synthesized through latest advances in genetic engineering Production costs slashed by a factor of 100

Attractive features • CO 2 Solution’s reactor operates at ambient temperature and atmospheric pressure – – Lower costs Sustainable development technology Favorable Life Cycle Assessment (ISO 14040) Can enrich methane-poor biogases by stripping their CO 2 content • The instant by-product is an easily manageable liquid solution of bicarbonate ions (HCO 3 -)

Ancillary benefits of the by-product • CO 2 Solution’s treatment unit: – instantaneously converts harmful CO 2 gas – into unharmful bicarbonate ion solution Valuable alternatives to CO 2 compression or liquefaction

Added value of by-product Several HCO 3 - recycling options: – Sequestration in saline aquifers • More affordable than piping CO 2 • Irreversible sequestration, no risk of CO 2 leak – Precipitation, e. g. into calcium carbonate • Commercial value in Pulp and Paper, etc. – Pure CO 2 regeneration through desorption • Valuable local production in remote areas

A plan of action for each industrial sector • CO 2 Solution has a plan of action for your industry sector – – – Coal-fired power plants Hydrogen plants and gensets Biogas enrichment for power generation Incinerators Cement, aluminum smelters, pulp and paper, foundry • CO 2 Solution’s plan of action can help you reduce your GHG emissions by 10% within 3 -6 years • This plan of action will be highly competitive with the increasing costs of CO 2 emission penalties
