THE WORLD'S FIRST HYDROGEN COMBUSTION OUTBOARD ENGINE!

EV Channels Review

This video provides an in-depth look at Yamaha's prototype hydrogen combustion outboard engine, a significant development in marine transportation's pursuit of reduced emissions. The reviewer highlights the core concept: burning hydrogen directly in a V8 engine, producing water as a primary emission. Key advantages discussed include the lightweight nature of hydrogen and the utilization of existing combustion engine technology. However, the primary drawback is the substantial challenge in achieving comparable range to gasoline counterparts due to hydrogen's low volumetric density. The prototype, based on a Regulator 26' hull, uses three 700-bar tanks, yielding an estimated range of only 46 miles compared to the gasoline version's 276 miles. The video thoroughly explores solutions for range extension, such as more tanks, higher pressure storage, and liquid hydrogen, while also detailing the engineering complexities of hydrogen storage, including tank expansion and the critical need for robust ventilation systems to manage potential leaks. Overall, it's presented as a promising, albeit early-stage, engineering proof of concept.
