What if Hydrogen (H2) and Renewable Natural Gas (RNG) replaced conventional Natural Gas (NG) for Combined Heat and Power (CHP) applications? What if Hydrogen and RNG are both produced in large enough quantities to fill most of the needs for operating CHP plants and microgrids? In this article, we’ll explore the different types of Hydrogen and RNG, their current market share, their future and market growth, and how it compares with natural gas, and see how much they could realistically shift natural gas consumption in the next few decades.
