Government Scientists More Efficient at Splitting Hydrogen

Government Scientists More Efficient at Splitting Hydrogen

Scientists at the Argonne National Laboratory have just made a breakthrough in bringing the hydrogen economy closer, by splitting hydrogen ten times faster. Hydrogen will become more useful in a carbon-constrained future, because it can store energy. But the most difficult part has been isolating a single hydrogen molecule in the first place so it can be worked with. Normally, hydrogen shows up only in pairs of atoms – as H2. Separating it out into single atoms is currently such an energy-intensive and expensive process that it is not cost-effective for energy storage. That is why the much touted future “hydrogen economy” has always remained “just around the corner”, despite hydrogen’s great promise as an important energetic element. Only small amounts are needed to make semiconductors. Today’s hydrogen fuel cells are very expensive. As Nenad Markovic, a senior chemist at ...
