Some experiences are already in place such as the BECCS at the corn-ethanol plant in Illinois, USA, supported by the US Department of Energy. In Brazil, the most common use (BECCUS) for CO2 is for soft drink industries, which buy carbon dioxide from some mills in the state of SP (for example, the Vale Onda Verde mill1, at Nova Granada). However, there are other possible uses, even with a higher benefit. In Parana State, Raudi Industries purchase CO2 from Copcana mill to produce sodium carbonate and to be fed in wood greenhouses as well2. This means that the main and most profitable sources for CO2 production associated to biofuel production are in the sugar/ethanol process, including fermentation process, upgrade process of biogas from vinasse and exhaust gases from the boilers. In addition, the use of CO2 from carbon capture is still a challenge, considering storage, transportation and economic feasibility.
RCGI/FAPESP/SHELL has already organized a first side event on BECCUS in EUBCE 2019 in Lisbon, funded by FAPESP, jointly with European Commission (SAM – Scientific Advice Mechanism and SAPEA)3, where these issues started to be discussed. The workshop has achieved a great success, as mentioned in the workshop final report. Besides the presentations of the research results from RCGI, there were two important lectures from EU scientists highlighting the importance of the subject to achieve Paris Agreements and to control global warming. After this event, RCGI has started discussing with Aalborg University the organization of a second workshop in this EUBCE 2020, in Marseille, France.
In this context, the main objective of this workshop is to present and discuss the perspectives for BECCUS and the existing experiences and challenges, comparing the experiences in Brazil and in Denmark. High-qualified speakers are invited, from Brazil, Denmark and, additionally, from The Netherlands, to present existing experiences and to discuss the challenges.
