Among the numerous "green" (clean) energy resources being developed, one that has received significant government and industry support is "blue" hydrogen. But this alternative fuel is actually very questionable. According to a major analysis by climate scientists Robert Howarth (Cornell Univ) and Mark Jacobson (Stanford Univ), "the greenhouse gas footprint of blue hydrogen is more than 20 percent greater than burning natural gas or coal for heat and some 60 percent greater than burning diesel oil for heat," Dr. Howarth explains what blue hydrogen is, how it is produced, and why we must consider the environmental and climate risks of developing this particular resource.
