Chemical-looping combustion (CLC) has unique potential for reducing energy and cost penalty for CO2 capture, as it avoids the costly gas separation of other CO2 capture technologies. Early deployment is seen in natural gas steam generation, where gas-to-steam efficiency penalty with CLC is below 1%-point compared to 15%-points with amine scrubbing and 8%-points with oxyfuel combustion, all for 95% capture rate. Reduction of the CO2 avoidance cost of 60% compared to amine scrubbing post combustion capture results from higher efficiency. An absolute necessity for the scale-up of reactors for this technology is the availability of adequate oxygen carrier material. SUCCESS will assure scale-up of oxygen-carrier production to the 100 tonne scale, as well as scale up of technology to 1 MW. Industrially available raw materials will be used to produce environmentally sound oxygen carriers based on two highly successful materials developed of the previous INNOCUOUS project. The work includes, i) applying the oxygen carrier production methods at industrially required scale and assuring the adequate performance, ii) development of standard for mechanical stability, iii) validation operation in four available smaller pilots <150 kW, of significantly different design iv) operation with gaseous fuels in a 1 MW pilot plant, representing a scale up of the state of art by one order of magnitude. v) detailed studies of reaction mechanisms and fluid-dynamics vi) use of results in optimization of a previous design for a 10 MW demonstration plant and techno-economic study of full-scale plant vii) assessment of health, safety and environmental issues associated with oxygen carrier handling including reuse or recycling strategies. viii) quotations for production of >100 tonnes of material Combined efforts of key European developers of CLC technology will assure the continued European leadership in this development and bring the technology a major step towards commercialization.

The transition to a biobased economy puts strong challenges on researchers and industry to develop sustainable processes. 2G biofuel plants use waste streams as substrates, but themselves generate a new waste stream of lignin-rich sludge that is left after saccharification of the carbohydrates. This waste stream is expected to exponentially increase with an increasing number of 2G bioethanol plants being built, according to a report of the International Energy Agency. FALCON aims to convert this lignin-rich industrial waste of 2G biofuel plants to higher value products, in particular shipping fuels, fuel additives and chemical building blocks. This would be the next consecutive step in turning waste to products, thus minimizing waste and simultaneously providing new alternatives for fossil resource based processes. The FALCON process is based on enzymatic and mild chemical conversion of the lignin waste stream, providing a more environmentally friendly approach to the production of fuels and chemical building blocks. FALCON takes full advantage of the lessons learned over the last 150 years in the petrochemical industry with respect to design of the processes. This implies an initial treatment at the 2G bioethanol plant, converting the waste to a lignin oil that can be more easily transported and also directly used as a low sulphur shipping fuel. It will be further converted into fuel additives and chemical building blocks in centralized facilities. To achieve this, FALCON has formed a consortium of industry (3), SME (4) and academics (2) covering the whole value chain from a 2G biofuel plant delivering the lignin waste to enzyme producers, chemists and process engineers to depolymerize the lignin to oil. End-users are a fuel and chemicals producer and a ship engine developer. This unique combination of expertise and infrastructure will ensure the development of three new value chains with a strong emphasis on the economical sustainability.
