“Feasibility, Operations and Maintenance of Pipeline Transportation of Hydrogen and Hydrogen Gas Blended with Natural Gas”

Saba Esmaeely, PhD. (USA) Integrity Engineer – DNV, Jason Goodhand, Global Energy Storage Leader, DNV, Ashwin Chandra, Senior Engineer, DNV, Ken Lee – Principal Engineer, Material Technology and Advisory, DNV will present Feasibility, Operations and Maintenance of Pipeline Transportation of Hydrogen and Hydrogen Gas Blended with Natural Gas.

Course Description

In recent years, the social and political landscapes have shifted the public’s focus toward an energy transition to cleaner fuels.  A key component for energy reliability is the use of hydrogen as a fuel; either in pure form or blended with natural gas.  New pipelines and North America’s existing pipeline infrastructure are a common-sense solution for transporting hydrogen gas and hydrogen blended gas from the location of production to end users.  This 5-hour session will step through the journey to determining the feasibility for using a specific pipeline considering specific operational parameters.

The training will provide engineers with a basic understanding of the differences between transporting natural gas versus blended natural gas.  It will also provide a methodical approach to determining the feasibility of transporting hydrogen gas or blended hydrogen gas through new and existing pipeline networks. In addition, the training will provide engineers with a more in-depth understanding of the material and integrity implications of transporting hydrogen in new and existing pipeline systems.

Course Outline

  • Hydrogen introduction (behavior and production)
  • Understanding state and federal regulations and the role of a safety management system
  • Design considerations; the significant differences between ASME B31.12 and B31.8
    • Prescriptive and performance-based options for determining MAOP
    • Welding and related hardness requirements
    • Pipe and fitting selection
    • Plant piping vs transmission piping
  • An overview of the potential impacts on pipeline threats, consequences and defect assessment (e.g. impacts on fatigue crack growth rates and fracture toughness)
  • Steps required to reach the trial stage of transporting hydrogen
  • Successful industry projects
  • A review of typical pipe materials within distribution and transmission pipeline systems an the anticipated compatibility with hydrogen
  • A walkthrough of the pipeline threats and the potential impact associated with transporting hydrogen and the potential interactions


  • Certificate of Completion awarding 5 PDHs
  • Course notes delivered electronically

Instructors’ Bio

Dr. Esmaeely is an Engineer working for DNV Energy. She has more than 15 years of experience in the energy industry developing understanding of materials behavior. Prior to DNV, Saba worked as a postdoctoral researcher at the Fontana Corrosion Center at The Ohio State University, focusing on environmentally assisted cracking and hydrogen embrittlement of steels and aluminum alloys as well as galvanic corrosion of noble materials in the nuclear waste industry, and aluminum corrosion in marine and aerospace applications. As a graduate research assistant her research was on internal corrosion, focusing on aqueous CO2 and H2S corrosion in the oil and gas industry. Dr. Esmaeely is currently leading multiple projects on the feasibility studies of blending hydrogen with natural gas at different blend levels as a steppingstone in transitioning to 100% hydrogen.

Jason Goodhand joined DNV in 2019 as the global business leader for energy storage. Jason has pursued a career focused on new energy technologies. With over 15 years of experience in the cleantech energy sector, Jason has developed and managed businesses and projects involving grid-scale renewable energy, hydrogen fuel cells, and energy storage in Canada and the United States. Jason’s role at DNV GL comes after 10 years with international energy giant ENGIE in various roles and locations, most recently its North American Storage group. Jason holds a Master of Business Administration degree from the Richard Ivey School of Business and a Mechanical Engineering degree from the University of Western Ontario

Ashwini Chandra is a senior engineer within DNV’s research laboratory based in Columbus, Ohio.  He joined DNV after his tenure at The Ohio State University as a graduate research associate.  While at DNV, Mr. Chandra’s responsibilities has led to the development of expertise in electrochemical and characterization techniques with focus on materials and corrosion related challenges in the oil and gas industry. The projects have included work on adsorption behavior of corrosion inhibitors, galvanic corrosion, carbon dioxide corrosion, coating evaluation, hydrogen embrittlement, stress corrosion cracking susceptibility and AC corrosion susceptibility of materials.  More recently, Mr. Chandra has managed a Joint Industry Project with 7 industrial partners from Oil and Gas Majors and equipment manufacturers, executed several projects related to materials qualification for offshore oil and gas development projects, and is currently pursuing study on the effect of hydrogen-methane blends on fatigue properties of line pipe steels.

Ken Lee has over 20 years of experience in pipeline safety. He is an internationally recognized expert on pipeline safety and arc welding. His areas of specialization include code compliance reviews, welding process optimization, non-destructive testing, mechanical testing, welding metallurgy, failure investigation, hydrogen assisted cracking, fitness for service, pipeline construction, strain-based design, line pipe and fitting requirements, research and training.
