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: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
