The Unfortunate Truth About Toyota's Hydrogen V8 Engine

Summary by Krater

The video analyzes the spatial requirements for storing hydrogen in a V8 combustion engine car to achieve a 300-mile range, comparing it to electric vehicle battery modules and demonstrating that gaseous hydrogen requires far too much space to be practical.

From the video

Answers: How much space does a hydrogen combustion engine car need to achieve a 300-mile range?

• hydrogen combustion engines
• hydrogen storage capacity
• fuel cell vehicles
• electric vehicle battery storage

What it concludes

• A hydrogen-powered Lexus RCF with a 10,000 psi gaseous hydrogen tank would only achieve a range of about 50 miles.
• Storing enough gaseous hydrogen for a 300-mile range in a V8 combustion car requires 21 5-gallon buckets, taking up 14.1 cubic feet, which exceeds the car's trunk space.
• A pre-2019 Tesla Model S battery module setup requires significantly less space than hydrogen storage to achieve a 300-mile range.
• Liquid hydrogen improves storage density by 75% compared to gaseous hydrogen at 10,000 psi, reducing the requirement to 12 buckets.
• Liquid hydrogen storage in vehicles presents severe challenges, including boil-off and safety restrictions against parking in closed-in spaces.
• Fuel cells are currently the best practical method for using hydrogen as a vehicle fuel source compared to internal combustion engines.
