In Massachusetts, Sossina Haile SB ’86, PhD ’92, the Walter P. Murphy Professor of Materials Science and Engineering at Northwestern University, in a recent presentation recent talk at MIT, unveiled a solution to hydrogen transport issues with a technology to use ammonia to “carry” hydrogen, and extract the hydrogen from the ammonia via devices that use cesium dihydrogen phosphate as an electrolyte, The “superprotonic” material allows positively charged protons to move through it and strips hydrogen from ammonia, leaving behind the nitrogen. Haile said: “It’s inexpensive, nontoxic, earth-abundant — all these good things that you want to have when you think about a sustainable energy technology.”
