Prepare CO2 capture and storage now for greater environmental benefit later

16.04.2007
CO2 capture and storage can make a major contribution to CO2 reduction in the Netherlands. By the mid-21st century 80 to 110 million tonnes of CO2 per year could be avoided in the sectors energy, industry and transport. This is half of the current CO2 emission. Moreover, this can be realised against acceptable costs concludes Dutch researcher Kay Damen.

To realise such reductions in CO2 emission, a clear and internationally-oriented vision and bridging strategy is necessary, so that the storage capacity that is released over the next few decennia can actually be used for CO2 storage says Damen. He investigated the technical possibilities, costs and risks of CO2 capture, transport and underground storage.

Electricity greatest potential

In 2020 15 million tonnes of CO2 per year could be avoided by capturing CO2 in the new coal-fired power stations yet to be constructed. Moreover, existing pulverised coal-fired power stations may also be equipped with CO2 capture installations, although the costs of this are relatively high. In 2050 the reduction potential is estimated to be 60 to 84 million tonnes of CO2 per year, for a scenario in which the electricity production is doubled.

By capturing CO2 in industrial processes a further 16 million tonnes of CO2 per year can be avoided. Further if cars are run on hydrogen or synthetic diesel produced from fossil fuels combined with CO2 capture then this could eventually lead to a difference of more than 10 million tonnes of CO2 emission per year. For the production of hydrogen in the transport sector, Damen investigated the thermodynamic performance and costs of decentralised membrane reformers. This new technology makes it possible to capture CO2 against relatively low costs.

CO2 transport and storage

Damen calculated the costs of the pipelines necessary to transport the captured CO2 to underground storage reservoirs. Gas fields are, in addition to deep saline aquifers and coal seams, the most suitable reservoirs for CO2 storage in the Netherlands. The capacity that becomes available for CO2 storage can, however, be limited by a series of geological factors, including the risk of CO2 leakage via wells and faults. Although the mechanisms of CO2 leakage are known, quantifying the risks is still a challenge. Additionally CO2 storage could compete with the underground storage of natural gas, especially if the Netherlands develops into an international gas 'roundabout'. If the Netherlands has to maximise its efforts on CO2 capture and storage then eventually one of the 'mega storage reservoirs’ will have to be released, for example, the Groningen gas field or large structures in the British or Norwegian part of the North Sea.

The doctoral research ‘System analyses of transition routes to advanced fossil fuel utilisation with CO2 capture and storage’ was part of the programme ‘Transition to sustainable use of fossil fuels’ that was funded by the NWO/SenterNovem Stimulation Programme Energy Research. The programme aims to develop knowledge in the natural and social sciences for the transition to a sustainable energy supply.

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“.

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.
