press release

Wetzlar – Bosch Thermotechnology is pushing ahead the market launch of future-proof energy systems. The company presents a power-generating heating system in the Energy section of this year’s ISH in Frankfurt, the world’s leading trade fair for sanitary, heating and air conditioning technology. This fuel cell-based system facilitates the decentralised generation of power and heat for new and modernised one and two-family homes. It is based on a ceramic solid oxide fuel cell, operating at high temperatures of 700° Celsius. This results in an electrical efficiency of 45 percent. Hence, the system operates more efficiently than other decentralised power and heat generators. The electricity costs for one and two-family homes can be cut by 25 to 40 percent. At the same time, carbon emissions are reduced by up to 50 percent compared to conventional power and heat generation.

As a member of the ene.field project, Bosch Thermotechnology will install some 70 of these power-generating heating systems for demonstration purposes in Germany, United Kingdom, the Netherlands and France starting 2014 in order to pave the way for the market launch. Aisin Seiki supplies the power-generating module, based on the appliance already launched in Japan. Bosch Thermotechnology integrates it into an overall system in accordance with the respective requirements of the individual European heating technology markets. The ene.field project is the largest European demonstration programme for fuel cell-based solutions facilitating the decentralised generation of power and heat for residential buildings. Industrial companies, research partners and utilities cooperate in the project to promote these micro CHP plants.

Both the electrical and thermal output of the fuel cell is 0.7 kilowatt, while the total thermal output of the fuel cell plus condensing heating device is rated at up to 25 kilowatts. A cell stack made from a ceramic material is at the heart of the power-generating module. The complete system comprising a fuel cell unit, a gas condensing device, a domestic hot water tank and a buffer tank has a footprint of only 0.7 square metres. All modular components are integrated into a compact housing measuring 1 800 x 1 200 x 600 millimetres (H x W x D). The intelligent integrated controller ensures that the power generation module, the gas condensing boiler and the tank are ideally matched for maximum efficiency. This optimises the service life of the fuel cell, the power output and the internal electricity utilisation, which in turn increases the overall efficiency of the system.

Background information on fuel cells
A fuel cell converts the energy that is stored in the hydrogen into electrical energy. The hydrogen is extracted from the supplied natural gas. In the fuel cell stack, the hydrogen initially reacts with the oxygen in the air and produces steam as a by-product. An inverter then converts the direct current into alternating current and feeds it into the building’s electricity grid. The heat produced in this process is used in the heating and hot water cycle.
