The U.S. government is putting $7 billion into building hydrogen hubs across the country. There is more than $50 billion in additional investments in hydrogen production and applications: cars, hydrogen production, trains, planes, stationary power and even ships.

Despite the promises of how the cleanest burning energy on the planet can mitigate carbon emissions, there is plenty of controversy and debate around whether we should or can develop a hydrogen economy.

Thomas Stephenson--Founder, Chairman and CEO of Pajarito Powder--a New Mexico-based supplier to the hydrogen industry, and one of the most knowledgable advocates for hydrogen power, joins us to chew over the latest news about hydrogen.
