C&EN Uncovered: Making hydrogen is easy; making it green is a challenge

Hydrogen might be the key to a clean energy future, but only if it can be made without fossil fuels. Most hydrogen today is made from methane.   With generous government tax credits and enthusiasm for sustainable technology, the race is on for green hydrogen.   Craig Bettenhausen, our usual host, guides C&EN associate editor Gina Vitale through the hydrogen rainbow and how the periodic table's number 1 element could become the number 1 fuel.   C&EN Uncovered, a new project from C&EN's podcast, Stereo Chemistry, offers a deeper look at subjects from recent cover stories. Read Bettenhausen's July 3, 2023, cover story about hydrogen electrolyzers at cenm.ag/hydrolyzers.   A transcript of this episode is available at cenm.ag/greenhydrogen.   Credits   Executive producer: Gina Vitale Host: Gina Vitale Cover story reporter: Craig Bettenhausen Audio editor: Brian Gutierrez Story editor: Michael McCoy Copyeditor: Sabrina Ashwell Show logo design: William A.
