A gas expansion engine uses excess pressure that occurs, for example, when natural gas is delivered to the municipal utilities

Excess gas pressure becomes electricity

In times of climate change, politics, business and society are sensitized to all aspects of efficient energy use. Not simply letting existing excess pressure energy go to waste, but using it sensibly was and is a central theme for Spilling. Decades ago, we developed a technology that is very interesting and economically worthwhile for municipal utilities that offer gas, electricity and heat to their customers - natural gas expansion with piston expansion engines.

The industry is making a lot of steam. But even experts are surprised when they hear that a good 20 percent of Germany's final energy consumption is accounted for by the generation of industrial process heat. In 2017, this was 2061 PJ, as calculated by the "Arbeitsgemeinschaft Energiebilanzen" (AEGB). In the 100 to 300-degree Celsius range, steam is one of the most important sources of thermal energy. Experts estimate that more than 150 million tons of steam are produced in Germany in oil and gas-fired boiler plants. This produces almost 30 million tons of CO2.

With good planning you can save a lot of money thanks to a support program

The recycling of steam with steam compressors from Spilling is now becoming even more attractive for the industry - their financing is supported in various ways by a funding program of the German Federal Ministry of Economics and Energy.

How to turn hazardous waste into electricity

The mountains of rubbish are growing. Experts estimate that around 255 million tons of waste are incinerated in about 2200 plants worldwide every year. Due to the legal framework, the proportion of waste incinerated in industrialized countries is significantly higher than in developing countries. In Germany, for example, the TA Siedlungsabfall (Technical Instructions on Municipal Waste) has prohibited the dumping of non-pretreated waste in landfills since June 1, 2005.

In the production of paper, recycled steam can save a great deal of money.


The range of applications for industrial drying is wide: It is used for drying sawdust for pellet production, plants (residues) for animal feed production, pulp drying, sewage sludge drying or the production of wood chips. Often enough, industrial product drying proves to be a very energy-intensive process.
