Small is beautiful – scientist proposes new efficient and eco-friendly power plants

27.09.2005


Power plants of the future may be designed to provide electricity solely for an individual housing estate, village, factory or college. That’s the prediction of University of Southampton engineer Dr Tom Markvart.



He claims large-scale systems of electricity generation used at present waste considerable amounts of energy by producing unwanted heat. It is also difficult to incorporate environmentally-friendly sources of energy such as wind farms and solar panels because of their intermittent and unpredictable outputs.

Dr Markvart, of the University’s School of Engineering Sciences (SES), is advocating the development of microgrids to provide a stable and reliable power supply from various energy sources. Small-scale generating equipment sited close to the eventual energy users could act as a stand-alone source of power, especially in remote areas, or be linked to the national grid. Energy storage devices would provide extra power at times of high demand. The proximity to customers would help boost energy efficiency to around 80 per cent compared to 35-40 per cent for a conventional generation system.


‘In the long term, microgrids offer the promise of substantial energy savings and reduction in emissions, without a major change in our lifestyle,’ said Dr Markvart.

Initiatives to test small-scale energy generation are already underway. They include the former Mont-Cenis coal mine in Germany, where a microgrid powers an academy, hospital and nearby housing. Ecologically-friendly ways of energy production include the Southampton Geothermal Project, which uses hot water from deep beneath the city.

Dr Markvart’s research appears in the latest edition of the Royal Academy of Engineering’s Ingenia magazine. The research was carried out in collaboration with, amongst others, Dr Suleiman Abu-Sharkh (SES) and Dr Neil Ross (School of Electronics and Computer Science), both also at the University of Southampton.

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.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
