The United Nations long-term climate goal of a maximum 2°C global surface temperature rise will require a tremendous reduction in CO2 emissions starting in the very near future. Sweden has stated ambitious targets for the reduction of the national CO2 emissions; zero emissions should be achieved by 2050. This is a tremendous technical, economic and political challenge, and even more so globally. All sectors need to be addressed in this challenge, although special emphasis will be required for heat and power generation, transportation, and, heavy industries (cement, iron & steel, petrochemical, pulp & paper, recycling etc). Therefore, to make our emission targets attainable, it is clear that cost-effective technology for achieving negative CO2 emissions will be necessary. Negative emissions are made possible when CO2 is separated and turned into a product or stored, and, when the CO2 originates from biogenic fuels.
To address these urgent needs, a ground-breaking technology has been proposed by the speaker and his colleagues at Chalmers University of Technology (CHALMERS), Sweden. The technology is based on a novel two-step selective oxidation process. The proposed technology will enable ultra-efficient conversion of fuels and chemicals combined with recycling of materials with the potential to enable negative emissions of carbon dioxide and zero emissions of other pollutants. In fact, the aim is to turn – what is today considered as waste or side streams – into useful products. With the selective oxidation process it will be possible to create new energy conversion processes.
Klas Andersson is a Professor in Combustion and CO2 capture technologies at Chalmers University in Sweden. His research is focused on chemistry and transport phenomena in combustion and CO2 capture processes. The work is based on experimental and theoretic research, which aims to provide generic knowledge on combustion and gas cleaning technologies. The overall objective is to contribute to a reduction of the environmental impact associated with the use of energy in various industrial applications. An important part of the research concerns new processes and
solutions that can be employed to achieve drastic reductions in CO2 emissions, in particular CO2 capture technologies. The studied applications are mainly industrial and
heat and power generation processes. Currently Klas Andersson is a visiting scholar at Brigham Young University; he works together with Professor Andrew Fry (Chemical Engineering Dept.), Professor Brad Adams and Professor Dale Tree (both at the Mechanical Engineering Dept.) to develop the next generation CO2 capture technologies through advanced combustion and gas cleaning processes.
