A significant examine in Nature Power, “Global greenhouse gas emissions mitigation potential of existing and planned hydrogen projects” by Terlouw et al, has finished one thing uncommon within the hydrogen hype bubble that’s slowly deflating. It has gathered hundreds of actual hydrogen initiatives world wide, run full life-cycle assessments on them, and drawn clear boundaries between what helps and what wastes effort. It has confirmed what many people have been arguing for years. Hydrogen is smart in just a few industrial purposes and little or no else. The proof matches the engineering logic.
The examine examined about 2,000 current and deliberate hydrogen initiatives throughout 20 years. It discovered that if each one among them had been constructed, the whole output would attain about 110 million tons of hydrogen per 12 months. That may include about 0.4 gigatons of emissions and at greatest offset between 0.2 and 1.1 gigatons of carbon dioxide annually. That contribution collapses by greater than 80% when the comparability is made to a future world that electrifies as an alternative. The researchers’ conclusion is easy. Hydrogen ought to go the place it replaces soiled hydrogen that already exists, not the place electrons do the job higher.
Most of right now’s hydrogen is used for fertilizer, refining, and methanol. That’s the world’s actual hydrogen drawback. It already produces…
