Decarbonizing transportation, heavy industry, and power may require low or zero carbon fuels.  Hydrogen is a popular favorite, and there are multiple technologies available that produce hydrogen for power generation applications.  But, they are typically described by a color instead of the actual production method.  Here's your secret decoder: >Grey = hydrogen produced from fossil fuels, typically natural gas>Blue = Grey hydrogen systems with the addition of carbon capture>Green = hydrogen produced via electrolysis of water using renewable electricity>Pink (red) = hydrogen produced via electrolysis of water with heat and/or electricity from a nuclear plant>Turquoise = hydrogen produced via pyrolysis of methane>White = hydrogen produced from biomass Jeff and Brian discuss these production pathways along with their challenges and requirements.  To learn more about the future of energy, visit GE's energy transition webpage at: https://www.ge.com/about-us/energy-transition For more information, please visit www.ge.com/power/gas and follow GE’s Power business on Twitter (https://twitter.com/GE_Power) and LinkedIn (https://www.linkedin.com/company/gepower/).
