The use of hydrogen as a primary energy source for vehicles provides challenges in terms of cost and system complexity, whether it is electrochemically-converted by means of a fuel cell or burned in an internal combustion engine, resulting in reduced efficiency compared to battery-electric vehicles. However, the increased gravimetric energy density of hydrogen onboard storage outweighs that of battery-electric energy storage in heavy long-haul transportation with high payload, potentially resulting in an increased driving range. The criterion for long lifetimes is currently determined primarily by proven internal combustion engine technology, in accordance with its benchmark. When used in conjunction with hydrogen, it carries the potential to combine technological advantages such as increased lifespan and reduced emissions.This presentation introduces the findings of a multiple-criteria decision analysis of technical and economic criteria and constraints on onboard hydrogen storage and conversion. It discovers storage conditions for pressure and phase in the available installation space, as well as technical development status updates for low-temperature polymer electrolyte membrane fuel cells and internal combustion engines with both direct and pre-chamber injection. The economic criteria comprise the costs of system components, including their bottom-up manufacturing cost and the total cost of ownership of the vehicles, including investment, operating, and fuel costs. The process for the derived decision-making considers the perspectives of vehicle manufacturers, suppliers, fleet operators as well as the goal of achieving greenhouse gas emissions targets in the transportation sector, in accordance with the revised EU regulation on CO2 emission standards for heavy-duty vehicles, employing a weighted sum model. The overall aim is to address the main interest groups and their anchor points for becoming first movers. |
