Renewable energy can be a lot cheaper

16.06.2005


Dutch energy policy is directed at 17 percent of electricity demand being covered by renewable energy sources by 2020. Martin Junginger has demonstrated that this can be achieved at considerably lower costs than is the case now. He also found that it might be more financially advantageous to realise part of the objective outside of the Netherlands because, for example, more space is available there for wind turbines or because more biomass is available there.



Renewable electricity can make a significant contribution to reducing greenhouse gas emissions and decreasing the dependence on fossil fuels. In particular the rate at which the production cost of electricity from land-based wind turbines can decrease, is something which most calculations and energy models have considerably underestimated up until now says Junginger in his Ph.D. thesis Learning in renewable energy technology development. Also the costs of electricity from wind parks at sea could fall by 25 to 39 percent by 2020. However several pilot plants will need to be constructed to realise this, and an improved exchange of knowledge will have to take place for the development of these technologies at a European level. The same applies to advanced power stations that gasify biomass with a high efficiency for electricity production. Therefore, the researcher also advises that learning processes and knowledge exchange for these technologies should be further stimulated at a European level.

Junginger used the experience curve approach is his research. This approach describes the cost development of a product or a technology as a function of the cumulative production. Researchers can use this to quantify cost reductions achieved in the past and to analyse possible future cost reductions. In addition, Junginger carried out a qualitative analysis for various sustainable electricity technologies to determine which learning mechanisms can bring about further cost reductions.


The doctoral research was carried out at Utrecht University via the Utrecht Centre for Energy Research and it formed part of the programme Accelerated Implementation of a Renewable Electricity supply in The Netherlands (AIRE) financed by NWO/SenterNovem. This programme is a joint initiative of SenterNovem and the NWO Social Sciences Research Council. Its aim is to develop knowledge in the natural sciences and humanities that will support the transition towards a more sustainable energy supply.

Martin Junginger’s research was funded by NWO/SenterNovem.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
