Study Notes

Hydrogen Supply Chain

Production: Grey hydrogen is generated from natural gas through steam methane reforming. Blue Hydrogen involves CO₂ capture during the reforming process.
Transportation: Involves pipeline networks, trucks, or ships. Can also be transported as a blend in natural gas pipelines.
Utilization: Hydrogen can be used in various applications including chemical feedstock, Combined Cycle Power Plants (CCPP) with Carbon Capture, Storage, and Utilization (CCS⁴), engines, fuel cells, refineries, and for production of E-fuels.
Storage: Is an essential component in the hydrogen economy, enabling the distribution of hydrogen when demand exceeds production.

Hydrogen Supply Chain

The lecture was on Hydrogen storage options, focusing on underground hydrogen storage as a part of the larger hydrogen supply chain.
The hydrogen supply chain consists of hydrogen production, transportation, and utilization.
Hydrogen production methods include grey hydrogen (produced from natural gas with CO₂ emissions), blue hydrogen (produced from natural gas with CO₂ capture), and green hydrogen (produced through electrolysis using renewable energy).
Hydrogen utilization methods include chemical feedstock, power generation (CCPP with CCS), engines, fuel cells, hydrogen-blended pipelines, and refinery energy applications.
The lecture was delivered on October 10th, 2024 by Dr. Lourdes F. Vega, Professor at the Chemical and Petroleum Engineering Department at the university.
Dr. Vega is the Director of the Research and Innovation Center on CO₂ and Hydrogen (RICH Center).
The lecture also included an invited speaker, Mr. Abdelateef Adam, a PhD student in the Chemical and Petroleum Engineering Department.
