DBFZ publishes Report about the energetic pathways for micro-algae

15.08.2013
As part of a joint research project, the Lausitz University, the Technical University of Freiberg and the German Biomass Research Centre (DBFZ) have studied and assessed several potential material and energy use pathways for micro-algae.

The goal was to specifically investigate the utilization of microalgae produced from flue gas of the facilities of Vattenfall. The final report of the project is now available online as DBFZ-Report 16 (www.dbfz.de) or as print version.

Several algae production plants in Germany and worldwide are already running or under construction. There is a huge research on the right production pathways. What often is missing is a specific research on the utilization of the produced algae and its comparison - especially when the algae are produced from flue gas. The DBFZ-Report "Algae Biorefinery – Material and energy use of algae” gives a detailed overview on existing processes for an energetic utilization of microalgae.

Algal biomass may be converted into energy by a variety of different means. A wide range of different conversion technologies are available for this purpose. They include physical, thermo-chemical, biochemical and biological treatments to create energy-rich products from the source biomass. In the report published mainly thermo-chemical conversion treatments like hydrothermal processes (liquefaction (HTL) and carbonization (HTC)), gasification and hydrogenation are investigated. Beside that the application of micro-algae as a substrate for biogas plants, for biodiesel production and as animal feed is researched too.

An energy balance is conducted for the Processes Biodiesel, Biogas, HTC, HTL and direct hydrogenation. To achieve specific results, the algae Chlorella vulgaris, Scenedesmus obliquus and Selenastrum rinoi were examined for their energetic potential in the investigation.

As a result, the report shows, that in general several pathways are possible, but great differences exist concerning the state of development and the energy efficiency of the processes.

The german version will be published shortly by the University of Freiberg.

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
