Comparing the two most sought-out forms of energy; each has its own advantages and disadvantages, but which one is the best to have?
Here’s a post from Visual Capatilist including the following:
According to the post,
- Energy Storage Battle: Visual breakdown comparing batteries and hydrogen fuel cells for energy storage.
- Technology Overview: Understanding the fundamental differences between battery and fuel cell technologies.
- Energy Density: Exploring which technology offers higher energy density for longer-lasting power.
- Charging Speed: Examining the charging speed of batteries and fuel cells, a critical factor for user convenience.
Here is a detailed comparison between BEVs and Hydrogen FCEVs:
Characteristic | Battery Electric Vehicles (BEVs) | Hydrogen Fuel Cell Electric Vehicles (FCEVs) |
---|---|---|
Power Source | Stores electricity in a large battery pack | Generates electricity using a hydrogen fuel cell |
Refueling/Charging | Requires charging at an electrical outlet or charging station, which can take hours | Refueled with compressed hydrogen gas at a dedicated hydrogen station, similar to refueling a gasoline vehicle |
Driving Range | Typical range of 100-300 miles per charge | Typical range of 300-400 miles per hydrogen tank |
Battery Size | Requires a large battery pack to store enough energy for driving range | Requires a smaller battery since the fuel cell is the primary power source |
Emissions | Zero direct emissions, but emissions from electricity generation | Zero direct emissions, only water vapor |
Infrastructure | Widespread network of public and private charging stations, especially in urban areas | Limited hydrogen refueling infrastructure, primarily in certain regions like California |
Efficiency | Battery-to-wheel efficiency around 70-90% | Hydrogen-to-wheel efficiency around 35-45% due to losses in hydrogen production and fuel cell conversion |
Cost | Battery costs have been declining, but still generally more expensive than conventional vehicles | Hydrogen fuel cell vehicles are currently more expensive than BEVs, but costs are expected to decrease over time |
