Scientists Work In The Development Of A System That Eliminates CO2 Emissions Through Microalgae

23.03.2007
Scientists of the University of Almeria, led by Gabriel Acién, are carrying out a research project on the development of new systems to eliminate carbon dioxide emissions thanks to the microalgae photosynthetic activity. This project, called CENIT CO2, is being developed by Spanish electricity company Endesa on the initiative of the Spanish Ministry of Industry.

On the pilot plant developed at the experimental station of Las Palmerillas, which depends on Spanish bank Cajamar, Almeria-based researchers try to prove the validity of this new method for eliminating CO2 emissions. It seems that in one year time, the system will be fully operative and therefore tests can be started at an industrial level. Researchers say that ENDESA, which is promoting this research line, may test its application in some of the facilities which, a priori, could show better results- the small gas plants.

’The mechanism developed is simple on paper. By the gas emission points a water tank would be installed in order to retain the pollutant gases resulting from a specific industrial process. This polluted water would go through a system of bioreactors with a microalgae culture system, which would then transform the CO2 emissions into vegetal matter and oxygen through the photosynthesis process’, researchers say.

This system also offers the added value of the resulting materials, as in addition to purified air, the organic matter obtained could be reused as fuel for biomass plants, transforming it into biofuel through fermentation or using it in agriculture.

Today, the single technology available with similar applications is based on the use of etanolamines, which do not have the added value microalgae have and also their applicability and profitability in industrial processes shows is not very satisfactory, the resulting gases being used for geological storage.

Greenhouses, another option to transform CO2

In parallel to the above, and in collaboration with Madrid-based company Besel, researchers are trying to use CO2 directly in greenhouses. This way, if a small combined-cycle plant was installed in a greenhouse area, the gas would be insufflated to the greenhouses and the actual plants would then contribute to its depuration before being emitted into the atmosphere.

Today, they are experimenting how much CO2 is beneficial for tomatoes, peppers and cucumbers, and in what distribution rate. It is already known that this gas can even double the production of vegetables (in fact, its use in agriculture is rather expensive) but the appropriate amount for its whole life cycle and the tolerable proportion of other substances have not been determined yet.

Both the State and companies hope to find a way to reduce the CO2 emissions by carrying out different research lines. Some research groups focus on optimising the existing technology, whereas others try to improve the gas storage techniques (for example, using tanks similarly to the way radioactive waste is stored). Other alternatives are the search for better solutions in the combustion process (the used matter burns more and emits less gases), gas capture (not only etanolamines) and the valuation of the emitted CO2, which is the field in which researchers of the University of Almeria are working on. All these ways are within the CENIT project framework, designed by the Spanish Ministry of Industry.

Other Spanish engineering and anergy companies, such as Unión FENOSA, Besel, Soluciona, etc, as well as other universities and Spanish research centres like Ciemat, the Spanish national research centre, and the universities of Alicante, León, Complutense and Rey Juan Carlos de Madrid, are also working on this R&D&I project, led by Endesa whose aim is to reduce the CO2 emissions of power stations.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
