Battery vs. Hydrogen Fuel Cell - The Ultimate Solution
Select Page

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,

Top management consulting experts for Bio-energy, EV, Solar, Green Hydrogen

  • 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:

CharacteristicBattery Electric Vehicles (BEVs)Hydrogen Fuel Cell Electric Vehicles (FCEVs)
Power SourceStores electricity in a large battery packGenerates electricity using a hydrogen fuel cell
Refueling/ChargingRequires charging at an electrical outlet or charging station, which can take hoursRefueled with compressed hydrogen gas at a dedicated hydrogen station, similar to refueling a gasoline vehicle
Driving RangeTypical range of 100-300 miles per chargeTypical range of 300-400 miles per hydrogen tank
Battery SizeRequires a large battery pack to store enough energy for driving rangeRequires a smaller battery since the fuel cell is the primary power source
EmissionsZero direct emissions, but emissions from electricity generationZero direct emissions, only water vapor
InfrastructureWidespread network of public and private charging stations, especially in urban areasLimited hydrogen refueling infrastructure, primarily in certain regions like California
EfficiencyBattery-to-wheel efficiency around 70-90%Hydrogen-to-wheel efficiency around 35-45% due to losses in hydrogen production and fuel cell conversion
CostBattery costs have been declining, but still generally more expensive than conventional vehiclesHydrogen fuel cell vehicles are currently more expensive than BEVs, but costs are expected to decrease over time
