Our energy system can be based on renewable energy

26.11.2008
We can change the Danish energy system to depend mainly on renewable energy and cut CO2 emissions by 50%. The big challenge lies in the system itself. This was one of the messages at DTU’s workshop on future energy systems.

For two days 160 scientists, businesspeople and government officers have been working to answer the question: What is the fastest way to an energy system with much less CO2 emissions? The first step is to integrate an interconnected intelligent power grid in Europe.

Denmark can become independent of fossil fuels by implementing efficiency improvements in all sectors including power stations, houses, industry and transport. At the same time, the share of renewable energy must be increased with more wind energy and increased use of biomass. In the transport sector we can replace fossil fuels with biofuels and we can also use electric cars which can be integrated into the power grid. The obstacle is the development of better batteries. Such a radical transformation of the energy system takes time. Accordingly, decisions and action are needed now. The transformation requires:

An interconnected intelligent power grid, integrated on a European level and able to store a higher level of renewable energy.

More research funds for new energy technologies and systems. We can achieve much with known technologies in the short term, but there is a need for research into new energy technologies and systems to enter the market after 2050.

Definite framework conditions and directives from the authorities. The energy sector needs this before beginning on huge investments in connection with a significant transformation of the energy system. For instance: instruments to promote the development of intelligent energy systems and stricter requirements for energy-using equipment, housing energy consumption, transport, etc. Such a development provides the Danish energy sector with great expansion opportunities on the international energy market.

Carbon capture and storage in power plants and energy-consuming industries seem to be necessary until we are able to phase out fossil fuels.

At the global level, all known sustainable energy technologies must be used in order to control CO2 emissions. The solutions are quite different in various regions of the world. In countries with rapidly growing developing economies like India and China it is obvious to expand with the best technologies, but it takes extensive international cooperation. In the world's least developed countries there is a need for providing modern clean energy and electricity to everyone. Here the world's major economies should help transfer clean energy technologies, based on both fossil fuels and renewable energy.

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
