ETH Zurich competence center ESC introduces energy strategy

25.02.2008
To even begin to combat climate change effectively, CO2 emissions have to fall sharply: to 1 ton per capita per year. According to researchers from ETH Zurich the way to the goal for this century is through an energy strategy based on the three Es: increased efficiency, renewable energy and electrification.
Long-term objective 1-ton CO2 society

In the past year, various reports from the United Nations' Intergovernmental Panel on Climate Change (IPCC) have warned the world in no uncertain terms that in order to achieve a stable climate on our planet by the end of this century, any increase in CO2 emissions in the coming decades must be curbed before the emissions can be appreciably reduced. According to the IPCC, the maximum amount of CO2 emissions that can be tolerated globally by the end of the 21st century amounts to roughly 2000 gigatons. This will mean a considerable reduction in the emission of CO2 per capita.

The per capita emission of carbon dioxide in Switzerland is currently 9 tons per year, approximately twice the global average. "Our objective for the climate and energy policy for the century has to be to induce each member of the human race to produce not more than 1 ton of carbon dioxide per year", Professor Ralph Eichler, President ETH Zurich, explained to the media today.

Systematic implementation of 3E strategy

This proposed emission target for carbon dioxide may seem ambitious by today's standards, but it can be achieved by the end of the century both in Switzerland and throughout the world. This is reflected in the calculations made by ETH Zurich's own Energy Science Center (ESC). In order to reach the target, an energy strategy will have to be consistently implemented. As stated by Profes-sor Konstantinos Boulouchos, the proposed strategy is based on three pillars: 1) the exhaustion of efficiency potential, 2) the extended use of renewable energy sources and 3) the increased share of electricity in the energy mix.

Exhausting the efficiency potential will mean increasing efficiency in every link of the energy conversion chain, from extraction at the energy source, through stor-age and distribution up to energy usage. This alone would harbour great sav-ings potential, especially when combined with market-based instruments to in-fluence the demand side.

The second E of the strategy focuses on the use of renewable energy sources, such as photovoltaics, water, and wind. Important to note is that economic as well as ecological aspects must be taken into consideration when using renew-able energy sources.

Electricity as the backbone of the energy system

The newcomer to the 3-E strategy constitutes the third E: electrification. Accord-ing to ETH Zurich researchers, in future C02 poor electricity will establish itself as the backbone of a sustainable energy system. It is increasingly being used in heating and cooling buildings (with heat pumps, for example), and is expected to extend to individual mobility (moving, in the long run, from hybrid vehicles to fully electric cars).

A reorientation of the energy system, however, will not happen overnight. It is likely to take several decades. All the more reason that it is crucial that steps be taken today: infrastructure in industrialized countries (transmission network, power plants) needs to be renewed and in threshold countries, erected.

Innovative research at ETH Zurich

ETH Zurich conducts intensive research with a mind to finding new solutions and methods to face the CO2 problem. Professor Marco Mazzotti from the Insti-tute for Process Engineering is researching the possibilities of eliminating CO2 in fossil-fueled power stations and combining it with stable and solid substances. This so-called mineralization thus facilitates the permanent and secure storage of greenhouse gases. Power electronics are becoming increasingly smaller and more efficient: the research group headed by Professor Johann Kolar from the Power Electronic Systems Laboratory is devoted to developing such compo-nents that are deployed, for example, in hybrid vehicles. Efficient control of the drive system of such cars makes a significant contribution towards environmen-tally-friendly private transport.

Promising ETH Zurich research is also being carried out in the field of building systems engineering. The technology at our fingertips today would already en-able us to replace CO2-emitting heating and boiler systems with a combination of innovative wall insulation and heat pumps - with free renewable energy from the ground. This ingenious concept is also just the ticket for existing buildings. "We just need to get cracking", explains Professor HansJürg Leibundgut from the Institute for Building Systems. Within five to six years it should be possible to produce the necessary components on an industrial level so that for the price of a mid-range car, a four-room apartment can be refurbished, with the effect that practically all of the CO2 previously generated by heating and warm water can be prevented.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
