Hydrogen Reality Check #1: Hydrogen Is Not a Significant Warming Risk

The Myth
Recent reports have suggested that large-scale production of hydrogen could do more harm than good in the effort to reduce global warming.

The Reality

The climate benefit from a well-regulated clean hydrogen economy outweighs the impact of any emissions that hydrogen would add to our energy system, especially if we prioritize hydrogen produced from renewables-powered electricity.

Realizing Hydrogen’s Potential
Hydrogen is a powerful tool for decarbonizing parts of the economy where electrification isn’t viable. It has the potential to reduce emissions by 11–13 kilograms of carbon dioxide equivalent (CO2e) per kilogram used compared to fossil alternatives. In processes like steelmaking, it can deliver even greater emissions reductions (abating 25–30 kg CO2e per kg H2 used). By deploying hydrogen at scale, the United States could abate roughly 15 percent of its yearly carbon dioxide emissions.

The realization of this potential depends on producing, storing, transporting, and consuming hydrogen in a way that minimizes emissions at each step. Every choice made in the hydrogen supply chain will be crucial in determining the ultimate emissions benefit achieved.

In clean hydrogen production, this means ensuring regulators and producers actively address the carbon intensity of the power supply, upstream methane leakage, and carbon capture rates. In theory, both “blue” and “green” hydrogen — the most commonly considered production pathways — can achieve close to zero emissions. For green hydrogen (produced by splitting water molecules), it requires the use of renewable electricity to power the electrolyzers. For blue hydrogen (produced from natural gas), near-zero production pathways require carbon capture technologies that can achieve unprecedented capture performance, as well as the near elimination of upstream methane leakage from the supply of natural gas...more
