We overview the progress made recently in pursuit of antihydrogen formation by the interaction of cold antiprotons, held in a Penning trap, with injected positronium atoms. We describe the relevant details of the antiproton catching scheme, based upon the PS200 trap, and our goals before antihydrogen can be observed. A method of accumulating low-energy positrons to provide the required large bursts of positronium atoms is described. The antihydrogen-formation rate for the simplest reaction is estimated, and its implications for the production and detection scenario are examined. An experiment to observe the charge-conjugate reaction, namely hydrogen formation in proton-positronium collisions, is summarized.
