Abstract

A device (1) for performing mechanical work and/or producing electrical or thermal energy, the energy necessary for operation is obtained from the oxidation of carbonaceous fuels (20) into carbon dioxide (24) and water (23). The device comprises means (14) for compression and/or condensation of the exhaust gas (21), and storage means (15) for receiving the compressed and/or condensed exhaust gas (21).

Claims

1. A device for performing mechanical work and/or for producing of electrical or thermal energy, wherein the device obtains the energy necessary for operation from the oxidation of carbonaceous fuels into a exhaust gas consisting essentially of carbon dioxide and water, comprising a device for compressing and/or condensation of the exhaust gas, and a storage means for receiving the compressed and/or condensed exhaust gas.

2. The device according to claim 1, wherein the device can be operated with oxygen-enriched air, preferably with an oxygen content >

95%, or pure oxygen as an oxidant.

3. The device according to claim 1, further comprising a heat exchanger for cooling the exhaust gas flow before and/or after the device for compression and/or condensation of the exhaust gas.

4. The device according to claim 1, further comprising a device for the condensation and/or separation of water from the exhaust gas.

5. The device according to claim 1, wherein the device is realized as a fuel cell or a thermal engine or a heating device.

6. The device according to claim 5, wherein the device is realized as a thermal engine, and that this thermal engine is an internal combustion engine, for example a piston engine or a turbine, with at least one combustion chamber for the combustion of fuel with oxygen-enriched air, preferably with an oxygen content >

95%, or pure oxygen, with means for converting the arising gas pressure or gas volume into mechanical work, with a feed device for bringing oxygen into the combustion chamber, and with a exhaust device for the removal of exhaust gases from of the combustion chamber, wherein a compressor for compressing the exhaust gases and/or a condensation device for the partial condensation of the exhaust gases are provided downstream of the exhaust device.

7. The device according to claim 6, further comprising a feed device for bringing water into the combustion chamber and/or into the exhaust gas flow after the exit from the combustion chamber.

8. The device according to claim 5, wherein the device is realized as a heating device, with at least one combustion chamber for combusting fuel with oxygen-enriched air or oxygen, means for transferring the resulting thermal energy to a fluid heat transport medium, a feed device for bringing oxygen into the combustion chamber, and an exhaust device for removing exhaust gases from the combustion chamber, wherein a compressor for compressing the exhaust gases and/or a condensation means for partially condensing the exhaust gases is provided downstream of the exhaust device.

9. A machine, in particular a mobile or stationary machine, with a device according to claim 1.

10. A device or installation for heating buildings, with a device according to claim 8.

11. A fuelling installation for fuelling a mobile machine or installation with a device according to claim 1 with gaseous or liquid fuels, comprising means for the removal of the compressed gases, in particular carbon dioxide, from a storage means of the mobile machine or installation.

12. The fuelling installation according to claim 11, wherein for fuelling the mobile machine or installation with oxygen or oxygen-enriched air.

13. A supply system for the supply of one or more consumers with gaseous and/or liquid fuels, comprising a first supply network for the transport of the fuels from one or more production installations and/or from one or more first storage means to the consumers, and a second return network for transporting back exhaust gases, in particular carbon dioxide, from the consumers to one of more production installations and/or to one or more second storage means.

14. A method for performing mechanical work and/or the for the production of electrical or thermal energy, in which the energy necessary for the operation is obtained from the oxidation of carbonaceous fuels into a exhaust gas consisting essentially of carbon dioxide and water, wherein the exhaust gases arising with the oxidation reaction are compressed and/or condensed and are captured in a storage means.

15. The method according to claim 14, oxygen-enriched air, preferably with an oxygen content >

95%, or pure oxygen is used as an oxidant.

16. The method according to claim 14, wherein the compressed exhaust gases are cooled before and/or after compression and/or condensation.

17. The method according to claim 14, wherein water is condensed out and/or separated from the exhaust gases.
