Twenty Hydrogen Myths
Summary
The document argues that the technical and economic barriers to a hydrogen economy have been largely resolved. It proposes a decentralized transition strategy starting with fuel cells in buildings and efficient vehicles, utilizing existing natural gas infrastructure as a near-term bridge to renewable sources. The author contends that hydrogen fuel cells are significantly more efficient than internal combustion engines, making hydrogen cost-competitive per mile driven despite higher energy costs per unit. The paper dismisses safety concerns, infrastructure costs, and environmental risks as myths, asserting that a well-designed transition would reduce oil dependence and carbon emissions without requiring a massive federal 'crash program'.
Key insights
- Hydrogen is an energy carrier, not a source, and can be produced from hydrocarbons via reforming, water via electrolysis, or experimental processes using sunlight or microorganisms.
- Hydrogen fuel cells are 2–3 times more efficient than internal combustion engines in vehicles, meaning hydrogen can be cost-competitive per mile even if it costs more per unit of energy than gasoline.
- The existing global hydrogen industry is already substantial, producing approximately 50 million metric tons annually, with about 48% derived from natural gas, 30% from oil, and 18% from coal.
- RMI proposes a decentralized transition strategy that begins with fuel cells in buildings to provide high-quality power and heat, then expands to fleet vehicles and general-market cars using onsite reformers to avoid costly new distribution infrastructure.
- Safety concerns regarding hydrogen's volatility are overstated; it is highly buoyant and diffusive, making it less likely to explode in open air compared to gasoline or natural gas.
- Onboard hydrogen storage is feasible using filament-wound carbon-fiber tanks, which are safer and more rugged than steel tanks; the bulkiness of these tanks can be mitigated by designing ultralight, low-drag vehicles.
- A transition to hydrogen could be self-financing and potentially cheaper than maintaining current gasoline infrastructure, with some estimates suggesting a saving of $1 trillion worldwide over 40 years.
- While natural gas is the logical near-term feedstock, the transition can move toward zero-carbon production via renewables or carbon sequestration without requiring new nuclear power plants, which the author deems uneconomic.
- Concerns that hydrogen leakage would harm the ozone layer or climate are based on unrealistic leakage rates (10–20%); actual industrial leakage is significantly lower, often around 0.1% to 1%.
