electricity supply: sustainable sources remain expensive

08.10.2008
TU Delft analyses electricity supply: sustainable sources remain expensive for the foreseeable future

The Dutch government’s ambitious environmental objectives for the electricity sector are only possible at a high price. This is one of the conclusions of researcher ir. Hans Rödel, who is to receive his PhD at TU Delft on Thursday 9 October. He recommends a combination of different modern generation technologies, CO2 capture and storage, the use of biomass and the recycling of waste heat.

The government wants to achieve a general CO2 reduction of 30 percent and to increase the proportion of sustainable energy sources within the total energy supply to 20 percent by 2020.

According to scientist Hans Rödel this can only be achieved at a very high price in the electricity sector. Scenarios involving a low environmental burden lead to high costs and vice versa. ‘One of the conclusions is that electricity from sustainable sources will for the foreseeable future remain more expensive than electricity generated from conventional sources.’

Combination
Rödel therefore recommends a combination of different modern generation technologies, CO2 capture and storage, the use of biomass and the recycling of waste heat. This can help create a sound environmental balance while containing costs within reasonable limits.

Rödel notes here that CO2 capture technology is still in its infancy and requires further development. Moreover, he believes that the environmental progress made as a result of rapid technological developments in the generation of electricity from fossil fuels is often overlooked.

Scenarios
Rödel developed a technological-economic simulation model which takes as its starting point the current range of generation facilities and which can be used to analyse future scenarios. He used this to create a future analysis of the Dutch electricity supply on the basis of four developed scenarios. The analysis took as its basis the existing, liberalised electricity supply and aimed to determine whether an effective balance could be achieved for the three key factors: environmental burden, cost of the electricity generation system and certainty of supply.

Rödel proposes that the government should at least determine and establish clear growth and stimulatory frameworks for the various production options. ‘Choices that are made now will influence the environmental burden, cost and availability of the system for the coming 25 to 40 years.’

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
