Have you ever wondered why fuel cell electric vehicles (FCEVs) have a battery? Of course, regular gasoline cars and diesel trucks have batteries too. The battery in the hydrogen fuel cell truck fulfills many of the same functions as those batteries, like providing the power to start the vehicle and for short-term use of functions like headlights, radio, windshield wipers, or alarm system when the engine is off.

Both battery electric and fuel cell electric vehicles are seen as viable emission-free options for heavy-duty trucking, but each have their own unique use-cases where they perform best. So, when exactly does it make sense to choose hydrogen and when does a battery do the trick?

Comparing Carbon Intensity & the Hydrogen Color Wheel The colors associated with hydrogen production, known as the hydrogen color spectrum or color wheel, try to convey information on the environmental impact of the production process.

While the color spectrum is easy to understand, it is too simplistic and can mislead people about the real environmental implications of hydrogen production.

You may have heard the term 'carbon intensity', used to describe the environmental impact of a producing a fuel. But what exactly does it mean, and how does it relate to hydrogen?

Pure hydrogen fuel is key to a zero-emissions world. It does, however, need to be extracted from other elements, such as oxygen or carbon, as it doesn’t exist naturally on its own. There are various methods to produce hydrogen, some cleaner than others. This is where carbon intensity comes in.

Diesel is powering and polluting the transportation industry. The transition to #hydrogen energy is a big challenge that requires leaders in fuel cell technology to continue innovating, expanding, and bringing down costs. Practical applications are possible today, using a localized approach to achieve big changes.

Do hydrogen vehicles pollute? While the transportation sector contributes 14% of global CO2 emissions annually, hydrogen fuel cell-powered vehicles produce only heat and clean water, no emissions.

How does a fuel cell vehicle work? Similar to a battery electric vehicle (BEV), a fuel cell electric vehicle (FCEV) uses an electric drive system. The key difference is in the energy storage. Hydrogen fuel acts as the energy storage in FCEVs. The fuel cell turns the energy into electricity to power the truck. Hydrogen replaces the gas or diesel, while the fuel cell essentially replaces the engine. The fuel cell takes in the hydrogen and produces the electricity needed to power the vehicle.

How is hydrogen produced? From the water we drink to the waste we throw out, hydrogen makes up 75% of all mass in the universe. It is in the water we drink, example, even in our trash. The U.S. makes more than 10 million metric tons of hydrogen annually.

Hydrogen is everywhere. It’s in our water, our and even in the trash we produce. The world generates 2 billion tonnes of municipal solid waste annually. Hyzon’s parter Raven SR has readily deployable breakthrough technology to convert this waste into hydrogen with low-to-negative carbon intensity.
