Abstract
This disclosure relates generally to vehicles with reduced emissions. More particularly, this disclosure relates to systems, methods, and apparatuses related to vehicles with reduced carbon dioxide emissions. The carbon dioxide emissions may be stored in a carbon dioxide clathrate.
Claims40
A method of sequestering emissions, the method comprising:
- storing gas clathrates in a clathrate storage vessel;
- separating stored gas clathrates into at least one gas and a host material, wherein separating stored gas clathrates comprises dissociating primarily only gas clathrates without substantially dissociating stored carbon dioxide clathrates;
- operating an engine of a vehicle utilizing the at least one gas as fuel;
- combining carbon dioxide from an exhaust stream of the engine with the host material, wherein the host material is compatible with forming carbon dioxide clathrates with the carbon dioxide of the exhaust stream;
- pressurizing and cooling the exhaust stream and the host material sufficient to form carbon dioxide clathrates with the carbon dioxide and the host material;
- and
- storing formed carbon dioxide clathrates in the clathrate storage vessel during operation of the engine.
4 more elements
A vehicle with reduced emissions, the vehicle comprising:
- a clathrate storage vessel configured to store gas clathrates and carbon dioxide clathrates;
- a separation system configured to dissociate the gas clathrates into a host material and at least one gas;
- an engine configured to utilize the at least one gas as fuel;
- a clathrate formation system configured to combine carbon dioxide from an exhaust stream from the engine, with the host material to form carbon dioxide clathrates;
- and
- an electronic control system configured to feed primarily stored gas clathrates to the separation system without feeding stored carbon dioxide clathrates to the separation system.
3 more elements
A vehicle with reduced emissions, the vehicle comprising:
- a clathrate storage vessel configured to store gas clathrates and carbon dioxide clathrates;
- a separation system configured to dissociate the gas clathrates into a host material and at least one gas;
- an engine configured to utilize the at least one gas as fuel;
- and a clathrate formation system configured to combine carbon dioxide from an exhaust stream from the engine. with the host material to form carbon dioxide clathrates, wherein the clathrate formation system is configured to control the pressure and temperature of the exhaust stream and the host material sufficient to form carbon dioxide clathrates with carbon dioxide and host material.

- a separation system configured to dissociate the gas clathrates into a host material and at least one gas;
- an engine configured to utilize the at least one gas as fuel;
- a clathrate formation system configured to combine carbon dioxide from an exhaust stream from the engine, with the host material to form carbon dioxide clathrates;
- and a dissociation vessel operably connected to the clathrate storage vessel, configured to receive carbon dioxide clathrates from the clathrate storage vessel, and configured for removal of stored carbon dioxide from the vehicle when the vehicle is otherwise not in use.
