swn build today on tomorrow's technology

Energy is becoming a more precious commodity. In order to save valuable energy, you have to go new ways. The use of renewable energy sources is an option that can be added to an interesting component: the investment in energy technology of the future. The LPR GmbH, Neuss, a specialist in holistic service and logistics services, has gone this route and sets in the energy-demanding everyday use on the efficiency of small fuel cell power plant. So they halve the current electricity costs and CO2 emissions.

"If you consume more than 25,000 kWh of electricity per year, should be based on a natural gas-powered micro fuel cell power plant on lenbasis set," explains Roland Gilges, Head of service contracting the swn. "Because this is a real alternative to the PV system - when it comes to generating your own electricity," he continues. The benefits of this cutting edge technology as well as the argumentation for a connection with full-service contracting convinced the Neuss and logistics service provider LPR GmbH completely, so that the company secured directly three devices of the brand BlueGen by the company Ceramic Fuel Cells. "We stand for technical service and logistics services. Therefore, we must addition to offices, especially our 12,000 square foot warehouse with electricity, "explains Stephan buses, member of management of LPR, the application range of the three devices. The Kunicki GmbH from Kaarst established contact between service provider and public utilities and, in collaboration with the municipal energy service implementation.

Efficient until the last corner
"We want to set not only in our home on renewable and future-oriented energy. Rather, we are already in Germany Service for network operators in the field of renewable energies. Therefore, we should also, from an economic point of view even such a system in use, "explains buses the concern for the installation of the fuel cell cascade and continues:" The units pay for themselves with their high degree of utilization of the beginning. The ratio of full-service price, electricity and gas purchases allows us direct cost savings. "With an electrical output of 1.5 kilowatts, the fuel cell micro power plant reached a unique high electrical efficiency of up to 60 percent. The overall efficiency increases to 85 percent by the use of waste heat, which delivers up to 200 liters of hot water per day. Thus, the degree of efficiency is divided into roughly two-thirds of current and third heat. In comparison, a conventional cogeneration (CHP), the electrical efficiency is the power side with a maximum of 30 percent - a third of electricity and two-thirds of heat.


Cost savings ³
In the case of LPR GmbH, the devices each running 8760 hours per year at full capacity. Less maintenance time, the duration of 8700 hours, which at 1.5 kilowatts, a total quantity per BlueGen of approximately 13,000 kilowatt hours of electricity means. This flow should no longer buy from the power company, the customer. At a current price of for example 20 cents per kilowatt hour that brings a saving of about 7,800 euros (2,600 euros per fuel cell) per year for three cells - and rising for the next few years. In addition, the current produced as CHP receives 5.41 cents per kilowatt-hour CHP support, the natural gas used is energy tax exempt. Overall, the three fuel cell units cover 15 percent of the energy needs of the enterprise with self-generated electricity.

Informative Energy Breakfast
To avoid the possibility of making direct contact to offer other interested parties, organize Stadtwerke Neuss in cooperation with the LPR GmbH therefore on 25 March 2014 at 8.30 clock a power breakfast at the premises at LPR on the Heerdterbuschstraße 2 41460 Neuss. There is the opportunity to inform the exchange with experts about the technology and its use.

Fuel cell means future
Who uses fuel cell technology, relies on efficient and clean power generation: It does not work as usual classic about combustion, but via an electrochemical reaction. "Due to the special hydrogen content of natural gas that is released and reacts with oxygen ultimately from the ambient air to the fuel cell. In the reaction of the two gases generates electricity. At the same time, the reaction starts a little heat is released, which is used to relieve the existing heating something - this saves additional "explains Gilges the technical principle of the fuel point. Special feature: The conversion of chemically stored energy of the used fuel into electricity and heat takes place without an intermediate step. This can cut their electricity costs about end users. Thus, the fuel cell technology resources, climate and budget preserves the same time. Andreas Ballhausen, Executive Vice President at Ceramic Fuel Cells (CFC), explained an additional bonus: "Despite the use of hydrogen, no special precautions are necessary because the gas is just as safe to handle as other fuels and gases also. The security of such systems, therefore, does not differ from that of conventional boilers. "
