A gas system includes a container, a fitting, a gas tube, adsorbent, and a filter. The container stores gas under pressure. The fitting covers an opening of the container and maintains a seal with the opening of the container. The gas tube is inserted through a bore in the fitting such that a length of a portion of the gas tube inside of the container is at least one half of a length of the container. The portion of the gas tube in the container includes holes. The adsorbent is in a particulate form and adsorbs gas in the container. The filter covers the holes in the portion of the gas tube in the container. The filter permits passage of gas into and out of the gas tube and prevents passage of the adsorbent into the gas tube.

1. A gas system comprising: a container configured to store a combustible gas under pressure, the container having an opening and a length;a fitting attached to the container and configured to engage the opening, the fitting defining a flow path into the container;a gas tube extending from the fitting flow path and into the container, the gas tube extending along at least one half of the length of the container, wherein the gas tube includes a plurality of holes;a quantity of a particulate adsorbent located in the container and outside of the gas tube, wherein the adsorbent comprises particles having a characteristic minimum size, and further wherein the adsorbent is selected to adsorb the combustible gas; anda filter coupled to the gas tube and configured to cover the plurality of holes in the gas tube, wherein the filter is configured to permit passage of gas into and out of the gas tube and to prevent the passage of adsorbent particles into the gas tube. 2. The gas system of claim 1, wherein the fitting is threadably attached to the opening of the container to form a seal with the opening of the container. 3. The gas system of claim 1, wherein the characteristic minimum size of the particles is greater than 5 microns and the filter is a mesh filter configured to prevent passage of the particles. 4. The gas system of claim 3, wherein the mesh filter is secured to the gas tube with at least two clamps. 5. The gas system of claim 1, wherein the filter is welded or bonded to the gas tube. 6. The gas system of claim 5, wherein the filter comprises a plurality of strips that are attached to the gas tube. 7. The gas system of claim 1, further comprising a temperature probe disposed in the container and imbedded in the particulate adsorbent and configured to monitor a temperature of the absorbent, and to provide a signal indicative of the monitored temperature. 8. The gas system of claim 7, wherein the temperature probe is disposed in a tube inserted into the container through a second bore in the fitting. 9. The gas system of claim 1, further comprising a thermal loop having a first end extending into the container, a loop portion disposed in the container and away from the gas tube, and a second end extending out of the container, wherein the thermal loop is configured to: (a) heat the adsorbent to facilitate desorption of gas from the adsorbent, or (b) cool the adsorbent to facilitate adsorption of gas to the adsorbent. 10. The gas system of claim 9, wherein the thermal loop comprises a thermal fluid loop configured to conduct a hot fluid through the container or to conduct a cold fluid through the container. 11. The gas system of claim 9 wherein the first end of the thermal loop extends through an entry bore in the fitting and the second end of the thermal loop extends through an exit bore in the fitting. 12. The gas system of claim 1, further comprising a device configured to deliver an electric charge to the adsorbent to generate heat and increase the release rate of the gas from the adsorbent. 13. The gas system of claim 1, further comprising a gas line configured to direct an outflow of gas from the gas tube to at least one injector configured to inject the directed gas into an engine, and a pressure regulator coupled to the gas line and configured to regulate a pressure of the outflow of gas such that the gas directed to the injector has a pressure in a range from 5 psi to 149 psi. 14. The gas system of claim 13, further comprising an electronic control unit configured to control at least the pressure regulator. 15. The gas system of claim 13, further comprising a fuel selector switch configured to selectively control a fuel source to the engine. 16. The gas system of claim 13, further comprising a vacuum pump configured to reduce pressure in the gas line to increase a release rate of the gas from the adsorbent. 17. The gas system of claim 1, further comprising at least one adsorbent dam configured to prevent the adsorbent inside the container from exiting the container via the opening of the container or another opening of the container. 18. The gas system of claim 1, wherein the adsorbent is configured to be inserted into the container via a tube passing through the opening in the container or another opening in the container by a vacuum coupled to the gas tube, such that the adsorbent is drawn from a source of the adsorbent into the container.
