Blue hydrogen in the car: More harmful to the climate than any diesel

However, a new study by renowned US scientists could cause the US government to have problems explaining it. Robert Howarth and Mark Jacobson, professors of environmental science at the elite universities of Cornell and Stanford, ask in the first scientifically based study on this topic: “How green is blue hydrogen?”. The clear answer: not green at all. The damage to the climate when using blue hydrogen is “over 20 percent greater than if you heat directly with natural gas or coal,” the scientists write, and “around 60 percent greater than if you generate heat with diesel.” In addition, the study assumes that CO2 can be stored indefinitely, which is “an optimistic and unproven assumption”. Even assuming that, “the use of blue hydrogen is difficult to justify from a climate perspective.”
