Far from being low-carbon, greenhouse gas emissions from the production of blue hydrogen are “quite high”, concludes a study by Robert W. Howarth and Mark Z. Jacobson, researchers at Cornell University and Stanford University, respectively, published 12 August in the scientific journal Energy, Science and Engineering.
