Abstract

The present invention is directed to improvements in storage and delivery systems that allow for rapid fill and delivery of gases reversibly stored in a nonvolatile liquid medium, improvements in delivery and purity of the delivered gas. The low pressure storage and delivery system for gas which comprises:a container having an interior portion containing a reactive Lewis basic or Lewis acidic reactive liquid medium that is reversibly reacted with a gas having opposing Lewis acidity or basicity;
