Energy Security
To reduce dependence on fossil fuels for energy security, the United States can turn to hydrogen as a promising alternative. With the transportation sector alone accounting for 70% of U.S. petroleum consumption, diversifying energy sources is crucial for a more resilient system. Hydrogen can be domestically produced from a variety of resources, including natural gas, coal, solar energy, wind, and biomass. When used to power fuel cell electric vehicles, hydrogen has the potential to strengthen national energy security by reducing dependence on imported petroleum.
Reducing dependence on fossil fuels
Dependence on traditional fossil fuels like gasoline and diesel poses risks to energy security. By transitioning to hydrogen, the U.S. can reduce its reliance on these finite resources and embrace cleaner, domestically-produced alternatives. As the country strives to balance supply and demand in the energy sector, hydrogen offers a sustainable solution that can help conserve petroleum and mitigate the impacts of fluctuating international markets.
Diversifying energy sources
To diversify energy sources, the U.S. needs to explore alternatives that are not only sustainable but also environmentally friendly. Hydrogen production from low- or zero-emission sources like solar, wind, nuclear energy, and advanced fossil fuel technologies can significantly reduce greenhouse gas emissions. By investing in hydrogen infrastructure for transportation, the country can move towards a more diverse and resilient energy system that prioritizes public health and environmental sustainability.
Key Takeaways:
- Energy Security: Hydrogen offers the potential to help strengthen national energy security by diversifying transportation energy options and reducing petroleum consumption.
- Public Health and Environment: Hydrogen-powered fuel cell electric vehicles emit only water vapor and warm air, providing a cleaner alternative to gasoline and diesel vehicles, which are major sources of air pollution.
- Fuel Storage and Production Costs: Challenges exist in storing hydrogen due to its low energy content by volume, but efforts are being made to increase storage efficiency. Additionally, reducing production costs of fuel cells is crucial for the competitiveness of hydrogen as an energy source.
Health and Environment
Zero-emission technology
One way that hydrogen fuel cells benefit public health and the environment is through their zero-emission technology. By producing only water vapor and warm air as byproducts, hydrogen-powered fuel cell electric vehicles offer a cleaner alternative to traditional gasoline and diesel vehicles. This can help reduce air pollution levels, particularly in areas where high emissions are a concern for public health.

Improving air quality
The transportation sector, accounting for about one-third of U.S. carbon dioxide emissions, plays a significant role in contributing to air pollution. The transition to hydrogen as a fuel source has the potential to significantly improve air quality by reducing harmful emissions from vehicles. Hydrogen-powered fuel cell electric vehicles emit only water and warm air, eliminating the release of nitrogen oxides, hydrocarbons, and particulate matter that contribute to pollution. This shift towards cleaner transportation options can have a positive impact on public health and the environment.
This switch to hydrogen as a cleaner fuel alternative not only benefits public health but also helps mitigate the environmental impact of traditional fossil fuel vehicles. By reducing harmful emissions and contributing to overall air quality improvement, hydrogen fuel cell technology offers a sustainable solution for transportation while addressing pressing environmental challenges. Embracing hydrogen as a zero-emission technology can lead to long-term benefits for both human health and the planet.
Costs to Produce
Economies of scale
If manufactured at scale, hydrogen fuel cell technology has the potential to become more cost-effective. According to a leading original equipment manufacturer, mass-produced fuel cell electric vehicles could achieve cost parity with hybrid vehicles by 2025. Unlike traditional batteries, where raw material costs are a significant factor, the primary expense of a fuel cell is in manufacturing the fuel cell stack itself. By increasing production volumes, economies of scale can be realized, leading to cost reductions and making hydrogen fuel cell technology more accessible and competitive in the market.
Government incentives and subsidies
One way to drive down costs and encourage the adoption of hydrogen fuel cell technology is through government incentives and subsidies. In the United States, the federal government has implemented programs to support the development and deployment of clean energy technologies, including hydrogen fuel cells. Government incentives can help offset the initial higher costs of hydrogen fuel cell vehicles and infrastructure, making them more attractive to consumers and businesses. By providing financial support and incentives, governments can accelerate the growth of the hydrogen economy and reduce greenhouse gas emissions from the transportation sector.

Challenges in storage and transportation
To overcome the challenges in storing and transporting hydrogen, several factors need to be considered. The energy content of hydrogen by volume is low, which presents a challenge in storage due to the requirement for high pressures, low temperatures, or chemical processes for compact storage. This poses difficulties, especially for light-duty vehicles that have limited space for fuel storage. Ensuring that the storage capacity allows for a driving range of over 300 miles to meet consumer needs is crucial, but the current need for larger tanks at higher pressures can impact vehicle weight and size limitations.
Advancements in hydrogen infrastructure
Hydrogen infrastructure developments are crucial for the widespread adoption of hydrogen fuel cells. Advancements in infrastructure include the reduction of production costs for fuel cells while maintaining performance. By 2025, mass-produced fuel cell electric vehicles are predicted to have comparable costs to hybrid vehicles, making them more competitive in the market. Additionally, reducing the cost of building and maintaining hydrogen stations is crucial for the growth of a hydrogen economy. Challenges in scaling up hydrogen infrastructure remain, but advancements in technology and cost reduction efforts are paving the way for a more sustainable and efficient hydrogen transportation sector.
Hydrogen Fuel Cell technology presents numerous advantages and challenges that must be carefully considered in the transition towards a cleaner, more sustainable energy future. From energy security to public health and the environment, the potential of hydrogen as a clean energy source is vast. However, issues such as fuel storage, production costs, and infrastructure development also need to be addressed for widespread adoption. Understanding the benefits and considerations of Hydrogen Fuel Cell technology is crucial for informed decision-making in the energy sector.
Conclusion
On the whole, hydrogen fuel cells offer numerous benefits such as near-zero greenhouse gas emissions, contributing to energy security, improving public health and the environment, and reducing carbon dioxide emissions in the transportation sector. With the potential to be produced domestically from a variety of resources, hydrogen holds promise for a more resilient and sustainable energy system. However, considerations such as the challenges in fuel storage, production costs, and the need for infrastructure development must be addressed to fully realize the benefits of hydrogen fuel cells.
