The Hydrogen Effect

摘要

The actual greenhouse gas reduction attributable to shifting to the hydrogen fuel cell depends heavily on the amount of carbon dioxide, methane and nitrous oxide released in the manufacture and delivery of the hydrogen fuel. These emissions can be expected to vary tremendously among the different industrial processes for producing hydrogen. Securing a climate-friendly hydrogen fuel supply system will require careful quantification of the greenhouse gases produced across the entire fuel life-cycle of potential hydrogen supplies, and a comparison of the results with a similar life-cycle assessment of the fuel for a conventional internal combustion engine.
