Steam recycling for industrial process heat helps to save energy and costs. In the end, the companies and the environment win.

Germany´s primary energy demand in 2019 was 13000 Peta Joule, which is about 3600 terawatt hours. In line with the approach of decarbonization through electrification, this amount of energy would have to be provided by renewable electricity.

No Energy turnaround without energy efficiency

Particularly in the question of energy system transformation and the desired decarbonization of energy supply, there is often talk of openness of technology.

But do we really have a choice?

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.
