Cost Comparison of Green Hydrogen with Other Low-Carbon Fuels
Overview of Green Hydrogen Costs
- Current Cost: Green hydrogen currently costs between USD $4-$6 per kilogram, largely due to the high cost of renewable electricity.
- Future Projections: Estimates suggest that green hydrogen could become more cost-competitive, potentially undercutting gray hydrogen by up to 18% by the end of the decade, with costs projected to reach around USD $3.7 per kg in the U.S. and USD $5.6 per kg in the EU by 2030.
Comparison to Other Low-Carbon Fuels
-
Hydrogen vs. Natural Gas:
- Cost Per Btu: Hydrogen is 3-5 times more expensive than natural gas in terms of energy content.
- Retail Prices: For automotive use, hydrogen costs are comparable to gasoline but significantly more than natural gas per unit of energy.
-
Hydrogen vs. Electric Energy:
- Energy Efficiency: Hydrogen for vehicle fueling is less efficient than electric vehicles (EVs) but offers advantages in storage and long-distance travel.
- Conversion Efficiency: Converting electricity to hydrogen is less efficient compared to using electricity directly in EVs.
-
Comparison to Other Hydrogen Variants:
- Green vs. Gray Hydrogen: Green hydrogen is currently more expensive than gray hydrogen but is expected to become competitive due to falling renewable energy costs.
- Blue Hydrogen: Produced from natural gas with carbon capture, blue hydrogen costs between USD $5-$11 per kg depending on the region.
- Brown Hydrogen: Made from coal, it can cost around USD $2 per kg, similar to some projections for green hydrogen by 2030.
Future Developments
- Technological Advances: Improvements in electrolyser technology and economies of scale are expected to reduce green hydrogen costs significantly, potentially below USD $2 per kg.
- Market Growth: The global demand for green hydrogen is projected to increase, driven by climate policies and technological advancements.
In summary, while green hydrogen is currently more expensive than gray hydrogen and natural gas, it is poised to become more competitive due to technological innovations and decreasing renewable energy costs. It offers advantages in terms of carbon footprint and versatility, making it a promising low-carbon fuel option for various applications.
