The proposed Mississippi Clean Hydrogen Hub reportedly will be up to 10 times larger than any other U.S. green hydrogen project and rank among the world’s largest such endeavors. Additionally, Hy Stor touts the long-duration hydrogen hub as a “model for our nation’s green hydrogen development efforts going forward.”

Unlike blue hydrogen, which uses natural gas as a feedstock, green hydrogen is produced with renewable energy and electrolysis. 

According to CC&L, electrolysis needs only two inputs to produce hydrogen — water and renewably sourced electricity. The only byproduct is...
