Can Toyota save the combustion engine by using liquid hydrogen?

No one has raced with liquid hydrogen! The technology is awesome, as it allows for a lot more hydrogen storage versus gaseous hydrogen (stored at 700 bar). Here, the low pressure liquid must be kept at -253ºC, however, which is quite a challenge. According to Toyota, this project had three main challenges: 1. Keeping the liquid hydrogen at a very low temperature. 2. Maintaining the efficiency and capacity of the fuel pump. 3. Controlling the pumped liquid hydrogen, as it converts to gas. We'll also discuss another issue that exist with hydrogen, which is how much space it takes up, despite having a better energy density by mass than gasoline. Unfortunately, the energy density by volume is quite a different story. Check out the video to see if this technology is worth the hype!
