Blue Hydrogen for CO2-Free, Fuel Agnostic Diesels

Decarbonization of transportation is a high priority in the battle to reach Paris Accord CO2 targets, but in heavy trucks and industrial power, there are few alternatives to fossil fuels with current technology. Cummins Inc., a large diesel engine maker, has developed a series of fuel agnostic diesel engines for commercial use that can run on diesel fuel, natural gas, or hydrogen gas. If run on blue hydrogen, CO2 emissions can be reduced or eliminated, and a new project at the world’s largest oil refinery will demonstrate blue hydrogen with low-cost carbon capture. The Reliance Industries Jamnagar refinery in Gujarat, India, will make blue hydrogen from syngas production, part of a coke gasifier process. Reliance expects carbon capture at 30 percent of the cost of atmospheric capture.Access all episodes of This Week in Engineering on engineering.com TV along with all of our other series.
