• Lab• Pilot

– Projects

Outline


Statements on CO2 emitting energy sources

• Cheap energy sources will be used by 3rd world countries as long as they are available

• Coal and oil are cheap and “easy” energy resources

• Renewable technologies will be beneficial for developed countries but will take longer to implement in the 3rd world

• Several industrial processes produce noticeable amounts of CO2 which may not be reduced by renewable energy

– Cement industry– Fermentation industry (Medicine, food, and bioethanol production)– Agriculture– Transportation

Danish power consumption and fossil fuels

• Power usage – Increase

• Coal<->biomass



CO2 Emissions and expectations

• 39% is power production

• German emission >300mio ton/y


• Kyoto 21%, – 1990-2012

Innovative solvent design

• Amino acids (Benedicte M. Lerche, Louise Sengeløv)– Low toxicity – Low volatility– Availability

• Ionic liquids (Subham Paul, SaravanamuruganShunmugavel)

– Low energy cost– Low volatility– Basic research

• Gas Hydrate (Peter J. Herslund)– High pressure – Promoters
