Emissions under control in coal combustion with new technology



VTT is developing technology that will allow fuels including coal to be utilised more efficiently in energy production; even without emitting any carbon dioxide.

In the new technology fossil fuels are combusted with pure oxygen separated from the air. Combustion gas consists mostly of carbon dioxide and water vapour. Carbon dioxide can be liquefied after cooling and stored in geological formations.


VTT is currently studying in co-operation with Foster Wheeler the phenomena relating to oxygen combustion using VTT’s test reactors in Jyväskylä. A larger co-operation project, with the objective of demonstrating oxygen combustion technology in the size of 30-50 megawatts is being planned around year 2010.

This technology has major significance for climate change, since about one third of carbon dioxide emissions caused by humans come from fossil fuels in energy production.

Less emissions soon also in practice

A circulating fluidized bed (CFB) boiler functioning with supercritical steam conditions has already been developed in a project coordinated by VTT and funded by the EU. Its carbon dioxide emissions are 15-20 per cent lower than those of traditional boilers. Foster Wheeler Energia Oy, Siemens PG and EnergoProjekt Katowice have been acting as partners in the project.

On the basis of the development work, Foster Wheeler is building the world’s largest CFB boiler of 460 megawatts of electric power in Poland. It is also the first CFB boiler with supercritical steam parameters and once through principle.

As a continuation to the successful co-operation project, a new three-year EU project has just been launched. Its objective is to design a circulating fluidized bed boiler of 800 megawatts of electric power, and for which efficiency will be even better and emissions lower.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
