Abstract
The invention provides a system comprising a closed stable comprising a stable space for housing ruminants, wherein the system is configured for controlling in a controlling mode a methane concentration in the stable air between a minimal methane concentration Cm−≥500 ppmv and a maximal methane concentration Cm+ selected to be equal to or smaller than the lower explosion limit of methane in the stable air CmLEL, and wherein the system is configured for controlling in the controlling mode a dinitrogen concentration in the stable air to be smaller than the ambient dinitrogen concentration in ambient air.
Claims17
A system comprising:
- a closed stable comprising a stable space for housing ruminants;
- a methane filter system comprising a methane filter configured for capturing methane (CH4) from stable air fed to the methane filter, to provide (i) filtered air to the stable air and/or to ambient air, and (ii) captured CH4 to a methane consumption system and/or to a methane storage system;
- a dinitrogen filter system, wherein the dinitrogen filter system comprises a dinitrogen filter configured for capturing dinitrogen (N2) from the stable air and/or from ambient air fed to the dinitrogen filter, and wherein the dinitrogen filter system is configured to provide the captured dinitrogen (N2) to the ambient air;
- and
- an oxygen filter system configured upstream of the methane filter and configured to lower an oxygen (O2) concentration of the stable air fed to the methane filter to at least below a limiting oxygen concentration for CH4, wherein:
- the system is configured for controlling in a controlling mode a methane concentration in the stable air between a minimal methane concentration Cm−≥500 ppmv and a maximal methane concentration Cm+ selected to be equal to or smaller than the lower explosion limit of methane in the stable air CmLEL;
- and wherein
- the system is configured for controlling in the controlling mode a dinitrogen (N2) concentration in the stable air to be smaller than the ambient dinitrogen concentration in ambient air.
A method for reducing gaseous emissions from livestock keeping, wherein the livestock comprises ruminants, the method comprising:
- housing the livestock in a stable space of a closed stable, wherein the stable space comprises stable air;
- controlling a methane concentration in the stable air by capturing methane from the stable air such that the methane concentration is controlled in the range of 500-45,000 ppmv;
- controlling a dinitrogen concentration in the stable air by capturing dinitrogen from the stable air such that the dinitrogen concentration is smaller than the ambient dinitrogen concentration in ambient air;
- and
- providing the captured methane to a methane consumption system and/or a methane storage system, wherein prior to capturing the methane from the stable air, oxygen is removed from the stable air to provide an oxygen concentration below 10 vol. %.
