Have you ever wondered what it would be like to drive a car that runs on hydrogen? Not many of us can say we've experienced it firsthand, but I had the unique opportunity to do just that. In this article, we'll delve into the world of hydrogen fuel cell vehicles, specifically the 2021 Toyota Mirai, and explore what it means for the future of sustainable transportation.
When Toyota offered us the keys to their latest hydrogen-powered vehicle, I'll admit, I was a bit hesitant. My background is in physics, not cars. However, I was excited to learn and to share this knowledge with you. So, we embarked on a two-week road trip, producing a series of episodes that dive deep into various aspects of renewable energy, with hydrogen fuel cells at the forefront.
Hydrogen fuel cell cars might not be common knowledge, but they are a fascinating alternative to traditional vehicles. Unlike battery electric vehicles, which require hours to charge, hydrogen cars can be refueled in about five minutes. But how exactly do they work? Let's open the hood.
The Mirai is an all-electric vehicle, powered not by a battery but by hydrogen. When you press the accelerator, hydrogen is released from the tank, travels through a valve, and meets oxygen from the air. This magical process involves a platinum catalyst that splits the hydrogen into protons and electrons. The protons cross a proton exchange membrane to meet the oxygen, creating water as a byproduct, while the electrons travel around the membrane, generating an electric current that powers the motor.
Driving the Mirai is a revelation. The silence of the fuel cell is striking, and the handling is impressive. However, the most significant difference from a gas-powered car is the planning required for refueling. Hydrogen stations are not as widespread, so you must plan your route carefully.
But why is Toyota investing in fuel cell technology when battery electric vehicles are already gaining traction? The answer lies in their commitment to reducing CO2 emissions by 90% by 2050. Toyota believes that a portfolio of electrified powertrains, including both battery and fuel cell electric vehicles, is necessary to achieve this goal.
The collaboration between automakers in the hydrogen and fuel cell space is also intriguing. In a world where competition is the norm, these companies have come together to create universal standards for fueling nozzles and receptacles, ensuring compatibility across different vehicles.
So, what's it like to be on the forefront of this technological change? Exciting, nerve-wracking, and filled with a sense of responsibility. We're not just experiencing hydrogen; we're witnessing the dawn of a new era in transportation.
If you have questions about hydrogen fuel cells or the Toyota Mirai, leave them in the comments below. I'll do my best to answer them, and maybe even delve deeper in our next video. Stay tuned!
