Накратко на български

Химическото газифициране на микроводорасли се изучава като метод за производство на биогорива от трето поколение. Това помага за намаляване на вредните емисии и осигурява енергия, без да се използват земеделски площи или гори.

Development of Chemical Looping Gasification of microalgae for the 3rd-Generation BioFuels production

The European Union recognizes biofuels as a key component for the continent’s strategy to combat climate change and enhance energy security. While the EU is making progress with biofuels by improving efficiency and sustainability, it is looking into new feedstocks beyond just food and wood that compete with food production and land use. Microalgae are non-food or non-wood biomass and don´t need farmland and forest resources. They grow quickly and are an abundant feedstock for use in biofuel production. The fuel derived from microalgae is called third-generation biofuel following the first- and second- generations from food and wood, respectively. Third-generation biofuel offers a more sustainable alternative as compared to the previous two generations, and this is essential to meeting future energy needs while reducing environmental impact. Microalgae can be converted into biofuels through several ways, and gasification technology stands out due to its outstanding ability to handle a wide range of feedstocks and to produce syngas (containing mainly CO and H2) that can be used for various purposes beyond just biofuel. Chemical-Looping Gasification (or CLG) is a rising star of the gasification family and has several key advantages over other gasification processes. One such advantage is the CLG´s good ability in handling “dirty” feedstocks, like microalgae (which have particularly high ash content). The CLG-G3BioF project combines the technological, societal and environmental merits of CLG and offers a novel and viable solution for third-generation biofuel production. These align well with the EU´s goals for reducing emissions and increasing renewable sources. Through this project, the microalgae-CLG technology is studied at different angles. The results turn out that the technology could play a win-win role for the production biofuels, which can help achieve a greener future for the European bioenergy chain.

Цел на проекта

Global warming is leading to serious climate consequences worrying the world. What’s worse, the global CO2 budget will be used up soon, likely before 2030. Therefore, actions for CO2 mitigation are urgently needed to meet the agreed climate targets. Negative Emissions Technologies (NETs) are possibly the only implementable option to tackle this problem in such short period. This project stands on a novel NETs technology called Chemical Looping Gasification (CLG) and aims at producing the 3rd-Generation BioFuels (G3BioF). CLG is an unmixed gasification using oxygen carrier to transfer oxygen for gasification, thus fuel and air never mix. In light of this unique feature, the gasification product is absent of N2 dilution (thus the CO2 capture is inherent), and in the ash-free air reactor heat-exchanger corrosion is less possible. Microalgae is biomass, a major source for G3BioF, but it has very high content of problematic ash impurities. However, CLG is hypothesized capable to handle this fuel, in addition to its negative CO2 emissions. This project will first select suitable oxygen carrier for microalgae-CLG, through intensive experiments in a batch fluidized-bed reactor and an 1.5 kW continuous pilot. The selected oxygen carrier will be used in a 50 kW dual fluidized-bed pilot for proof of concept and performance optimization. A process model with reaction kinetics details will be established and used to analyze the technology integration with downstream processes. Finally, Life Cycle Assessment (LCA) will be applied to the process chain to evaluate the environmental impacts. This is expected to identify the most promising integration having the best economic and lowest environmental impact. Through the project, the applicant will progress as a scientist and gain at least skills of LCA, complex pilot operation, tar analysis. This project is ambitious for a much greener production of biofuels and the results are important to power a sustainable future.
