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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
