Partnership Biogas I
At the beginning of 2019 CCS started a cooperation with the dairy farm of Erik Back in Lutten. This project Partnership Biogas I focuses on the production of green gas from a mono-manure digester. The goal is to ferment more than 20,000 tonnes of cattle manure. The green gas produced by the installation will be fed into the local gas network.
Green gas is produced, using our own biogas upgrading system: the Bio-UP. This innovative system has been developed by CCS and makes it possible to convert biogas to green gas on a farm scale. The system is energy efficient because little methane gas is lost in the process. In addition, the Bio-UP works under low pressure, the system is low-noise and there are few wear parts. The Bio-UP is the installation that pays off on a small scale.
Digesters on farms usually produce biogas for heat and electricity. They do this by means of a combined heat and power (CHP). However, a CHP produces 30% electricity and 70% heat. Because for many farms this heat production is not useful, a lot of energy is lost in this way. In the case of the Bio-UP this problem does not exist, because the biogas is upgraded to green gas. As such it is possible to use 99.8% of the available biogas. All the gas can be fed directly into the local gas network, or sold as transport fuel. In this way we valorise the biogas in a useful manner.

CCS Energie-advies has the vision to make mono-manure fermentation a standard solution in the future. The Biogas I partnership in Lutten is the beginning of this larger idea. We strive for a future in which all (larger) cattle farms ferment their own manure. This is not only financially interesting for the cattle farmers, but also helps to make the agricultural sector more sustainable. As an indication: the 20,000 tons of cattle manure that the digester in Lutten will ferment avoids a total of 800 tons of CO₂ emissions per year. If we ferment the cattle manure on a national scale, the impact on CO₂ emissions will be considerable.
