- Reduced Energy Loss
- Lower Emissions
Battery electric technology provides higher energy efficiency. Battery electric vehicles (BEVs) convert over 80% of the electrical energy from the grid to power at the wheels. In contrast, hydrogen fuel cells typically convert only about 60% of the energy from hydrogen to power at the wheels. The U.S. Department of Energy highlights this efficiency gap, indicating that BEVs make better use of energy sources.
Battery electric technology benefits from established charging infrastructure. Many regions have invested heavily in public and private charging stations for BEVs. In contrast, hydrogen fueling stations are still relatively scarce. According to the Alternative Fuels Data Center, there are over 41,000 charging stations in the U.S. but only about 100 hydrogen stations.
Battery electric technology has lower operating costs compared to hydrogen fuel cells. The cost of electricity is generally less volatile than hydrogen, which can fluctuate based on production and distribution costs. A report by Bloomberg New Energy Finance (2020) indicated that BEVs are expected to achieve lower lifetime costs in the coming years.
Battery electric technology requires simpler maintenance. BEVs have fewer moving parts than hydrogen fuel cells, which translates to reduced wear and tear and therefore lower maintenance needs. This makes them more appealing for consumers who prioritize convenience and reliability.
Battery electric technology offers faster refueling times for certain situations. While refueling hydrogen vehicles can take about 3 to 5 minutes, charging a BEV can take anywhere from 30 minutes to several hours depending on the charger type. Rapid charging stations can deliver a charge in as little as 15-30 minutes, which provides a competitive advantage.
Battery electric technology reduces energy loss. The process of producing, transporting, and using hydrogen fuel incurs significant energy losses. According to the National Renewable Energy Laboratory (NREL), as much as 80% of the energy from electricity used to create hydrogen may be wasted. In comparison, delivering electricity directly to an electric vehicle minimizes energy losses.
Battery electric technology results in lower emissions. BEVs produce zero tailpipe emissions, while hydrogen fuel cells may still rely on fossil fuels for hydrogen production in many cases. The Union of Concerned Scientists found that even when accounting for emissions from electricity generation, BEVs still outperform hydrogen vehicles in terms of overall greenhouse gas emissions.
While hydrogen fuel cells offer longer range and quicker refueling times, the substantial advantages of battery electric technology in efficiency, infrastructure, and overall operating costs make them a more favorable option for many consumers today.
How Is the Charging Infrastructure and Refueling Process Different Between These Technologies?
The charging infrastructure and refueling process differ significantly between hydrogen fuel cells and battery electric technology. Hydrogen fuel cell vehicles require hydrogen refueling stations.
