Hydrogen first began to attract attention as a renewable fuel over a decade ago, with R&D programs established under the George W. Bush administration and former California Gov. Arnold Schwarzenegger’s dreams of a “hydrogen highway.” But after being pushed aside due to cost issues and lack of adequate technology, the so-called hydrogen economy is on the rise in the U.S. once again.
The U.S. Department of Energy is reviving a number of programs to spur hydrogen development in the private sector. And both companies and academic researchers are responding in kind.
When burned, hydrogen is a zero-emissions fuel. But the No. 1 source for hydrogen is still natural gas — a fossil fuel with a significant environmental impact related to extraction. But the latest in hydrogen economy development is out to change that with renewable hydrogen solutions for a sustainable fuel future.
