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.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
