Consultant for hydrogen infrastructure and energy systems including hydrogen safety, systems design, connectivity to diverse energy systems such as offshore wind, natural gas infrastructure, and prominent end use applications including transportation

Research and development for the advancement of hydrogen as an enabling component in renewable energy systems. The Hydrogen Production, Power, and Storage group focuses on solving hydrogen infrastructure, integration, performance characterization, and scale up challenges. Areas of emphasis include the following; 1. Heavy-duty vehicle fueling including support of fueling methods, station architectures and operations, fast-fueling development, modeling of components and subsystems. 2. Hydrogen production through electrolysis with a focus on polymer electrolyte membrane systems, integration of hydrogen production with renewable/nuclear/grid power systems, control interfaces, scenario and component modeling, and hardware-in-the-loop evaluation. 3. Hydrogen component reliability primarily for dispenser components in H70T40 fueling and compression components for light and heavy-duty applications4. Hydrogen and contaminant sensor development, characterization, and deployment covering applications such as leak detection at stations and in C1D2 subsystems and fuel purity QA/QC 5. Scaling applications including progression to MW and multi-MW electrolysis stack operations and coupling to larger electrical systems, storage and end use6. Coupling assessments of hydrogen systems with wind (land/offshore), marine hydrokinetic, marine propulsion, data center primary and backup power, DC fast charging of BEVs, etc.
