Hydrogen is a high-energy, zero-emission fuel choice for vehicles. When used in fuel cells, it produces electricity to power an electric motor. It's suitable for larger vehicles where battery weight could be prohibitive. Hydrogen fuel is also appealing because it can be produced from various domestic resources, potentially reducing dependence on imported oil.
Hydrogen offers several advantages over traditional fossil fuels. It can be produced from water, making it almost inexhaustible. Hydrogen combustion is clean, with water being the only byproduct, compared to the CO2 and other harmful emissions from gasoline or diesel. The main challenge for hydrogen is the current lack of infrastructure for distribution and refueling compared to established oil networks.
The primary environmental benefit of using hydrogen fuel cells in trucks is the significant reduction in harmful emissions. Fuel cells emit no pollutants—only water vapor and heat. This can contribute to improved air quality and a reduction in the transportation sector's impact on climate change.
For long haul trucking, hydrogen fuel cells offer a solution that could balance range, weight, and refueling time. They can supply a similar range to diesel trucks and can be refueled in a comparable timeframe. This means that trucks can spend more time on the road and less time at charging stations, which is crucial for the economics of freight transportation.
Hydrogen is an energy carrier with qualities that can help reduce the net sum of greenhouse gas emissions by reducing reliance on fossil fuels, while keeping some of their innate benefits, such as fast-refueling capabilities.
Hydrogen itself is a colorless gas but there are around nine color codes that explain the source, or process used to make it.
