While modern coal-fired power plants like in Lippendorf and Lünen provide relatively high electrical efficiencies, their overall fuel utilization remains limited. Combined heat and power plants close to town in Bautzen and Chemnitz are able to use more of the heat available from electricity generation.

Green Electricity Close to Production Site

In physical terms, the Vestas rotor-blade plant in Lauchhammer gets its electricity from an on-site biomethane power plant as well as from a nearby wind turbine. Economically, the power-supply model is considerably more complex.

The press manufacturer Schuler is working on new technologies to cut energy consumption in half at an automobile stamping plant. Achieving similar potential savings in overall car-body manufacturing has turned out to be more difficult.

Up until recently, the operators of biogas plants were only concerned with producing and supplying as much electricity into the grid as possible. Now it can pay to produce electricity when demand is highest.

Coal gasification is considered a key technology for the long-term switch to carbochemistry. The greenhouse gas carbon-dioxide will one day be entirely integrated in chemical products and fuels, according to the International Freiberg Conference on IGCC & XtL Technologies (IFC) in Leipzig.

Less Carbon Conversion Means More Biomethane

The standard production processes of bioenergy sources can be greatly simplified using a new procedure. Scientists from Leipzig, Bremen and Karlsruhe are researching the biological and technical requirements for it. February 6, 2012

 

A new biogas technology is capable of producing this renewable energy resource precisely when it is needed for the production of electricity. Biodegradable waste is increasingly being used as an input. 10/2011

Power-exchange price more consistent with green electricity

Solar and wind power are naturally quite irregular in terms of production and supply to the grid. The Epex Spot power exchange has coped with these fluctuations in supply rather well over the last year and a half. 07/2011

The watery residue from bioethanol production used to be disposed of on farm fields. Verbio, a Leipzig-based bioethanol producer, is now using it in a new procedure to produce biomethane in natural-gas quality as well as organic fertilizer. The company has thus added two new, high-quality products to its portfolio while improving its greenhouse balance sheet. 12/2010

Solartrabi_kleinScientists have presented a concept of how German energy supply can be wholly converted to renewable energy by the year 2050. It’s really a matter of political decision-making, said Wolfgang Eberhardt, managing director at the Helmholtz Center for Materials and Energy. 10/2010

Könnern kleinGerman scientists have come up with a procedure for storing surplus wind and solar electricity as biomethane. The upgrading of biogas to natural-gas quality is making particular headway in Germany, Sweden and Switzerland. Yet the basic parameters still need to be set for the international transport and trade of biomethane. 04/2010

VW_Sachsen_kleinGerman industry could save twenty-five percent of its energy consumption by consistently applying existing efficiency technologies. While industry managers adopt a new way of thinking, scientists are working on the vision of a resource-efficient factory. 12/2009

Könnern kleinIn Germany, some 4,000 plants produce biogas which is used to generate electricity. The latest trend is for plants to convert biogas into biomethane, which is then fed into the gas grid. By 2020, some 6% of the gas that flows through the German grid must be from renewable sources. 07/2009

Control room smallGerman gas providers coped remarkebly well with the supply disruption in January. They even managed to supply extra gas to hard-hit customers in Eastern Europe. Even so the companies are expanding their storage capabilities and looking for alternative supply routes. 02/2009

Erik Saether smallEuropean energy exchanges may be undergoing a process of consolidation, Erik Saether, ceo of Nord Pool Spot (NPS), is not eager at this moment to merge with his European competitors. ‘It will be better for Europe if local markets are improved first.’ 02/2009

Nord Pool small 100x71After its recent partnership with the US-Swedish stock exchange operator Nasdaq OMX, the Nordic power exchange Nord Pool is looking for further international expansion. The next target is the UK. 02/2009
