Abstract: Provided are methods for storing a gas. An example method comprises providing a vessel containing a manifold system and an adsorbent, the manifold system comprising: a gas tubing, a filter disposed over openings in the gas tubing, a pressure relief valve, and an inlet coupled to the gas tubing and the vessel. The method further comprises introducing the gas into the manifold system via the inlet; circulating the gas in the gas tubing; flowing the gas through the openings in the gas tubing; and adsorbing the gas onto the adsorbent.

Abstract: An insulated rear head for a tank comprising an outer head and an inner head. The inner head is spaced away from the outer head, creating an insulation cavity. The insulation cavity is filled with an insulating material to prevent heat gain or loss from the product contained within the tank.
