Saudi's Transition to Green Hydrogen Fuel: NEOM Hub & Clean Energy Agenda
Saudi Arabia is taking steps towards carbon neutrality with initiatives like NEOM, a hub for green hydrogen fuel production. Hydrogen fuel, especially H2, is seen as a clean-burning alternative for large transportation like planes and ferries. However, the methods of hydrogen production differ in terms of environmental impact; while electrolysis offers a clean option, methane gas production from fracking can result in emissions of CO2 and CH4. Blue hydrogen fuel production involves CCS technology to capture CO2 emissions, showcasing a dual approach to cleaner energy solutions. Learn more about the green initiatives driving the utilization of hydrogen fuel in a sustainable manner.

NEOM: A Hub for Green Hydrogen Fuel (H2) Production Image source: https://www.sensonics.co.uk/blog/vibration-monitoring-green-blue-hydrogen-projects H2 produced by electrolysis (requires energy): 2 H2O(l) 2 H2(g) + O2(g) Zoom Poll!!
What is Hydrogen Fuel (H2)? Video: How Does a Hydrogen Fuel Cell Work? https://www.kuow.org/stories/first-hydrogen-ferry- launches-in-bellingham https://www.bbc.com/future/article/20220316-the- epic-attempts-to-power-planes-with-hydrogen The transportation sector has a need for energy dense fuels to power large/heavy transports (planes, ferries) = H2 fuel
Hydrogen Fuel (H2) is Clean Burning* * Clean burning means no CO2 is emitted directly from the combustion of H2 fuel. However, CO2 and other greenhouse gases (CH4) are omitted indirectly during H2 fuel production. Video (1 minute and 20 seconds): How Does a Hydrogen Fuel Cell Work? Highly combustible H2 fuel (a redox reaction!): 2 H2(g) + O2(g) 2 H2O(l)
Hydrogen Fuel (H2) Can Be Produced Using Methane Gas from Fracking This type of H2production is NOT clean burning because CO2 and other greenhouse gases (CH4) are omitted during H2 fuel production. Image source: https://www.sensonics.co.uk/blog/vibration-monitoring-green-blue-hydrogen-projects CH4 from fracking, H2 production at high temps: 2 CH4(g) + 3 H2O(g) 8 H2(g) + CO(g) + CO2(g) Zoom Poll!!
Blue Hydrogen Fuel (H2) Production Uses CCS* to Capture CO2 Released *CCS is Carbon Capture and Storage, a technology that captures CO2 at the place where it is first released to the atmosphere. This contrasts to DAC, which attempts to capture CO2 molecules present at much lower concentration because they have already spread (diffused) through the atmosphere.
