An article about this was first written in May 2010 and this article is an update for October 2024. The summary is that hydrogen is still making progress, it is in use and green hydrogen still has tremendous potential.
Recent Advancements in Hydrogen Production
Scientists have made significant strides in developing more efficient and cost-effective methods for producing green hydrogen, a clean energy source that could revolutionize our approach to sustainable power[1]. Recent breakthroughs include:
- The discovery of an inexpensive molybdenum-oxo metal catalyst that can generate hydrogen from water, including seawater[1].
- Development of advanced electrolysis techniques that significantly improve the efficiency of hydrogen production from water[2].
- Integration of renewable energy sources like solar and wind power to drive the electrolysis process, making hydrogen production entirely carbon-neutral[2].
Hydrogen Powered Cars in California in 2024
Based on the search results, the hydrogen fuel cell vehicles (FCEVs) currently available or in development include: Toyota Mirai, Hyundai Nexo, Honda CR-V e:FCEV, BMW iX5 Hydrogen, Toyota GR Yaris H2 (concept), Toyota Hilux Hydrogen (prototype), Hyundai N Vision 74 (concept), NamX HUV (concept), and Hyperion XP-1 (concept). Previously, the Honda Clarity Fuel Cell was also available, but production has ended. It’s worth noting that while these models exist, availability is extremely limited, with most hydrogen vehicles concentrated in California due to the presence of hydrogen refueling infrastructure[17][18][19][20][21]
The Promise of Green Hydrogen
Green hydrogen, produced using renewable energy sources, offers numerous advantages as a clean fuel alternative[5]:
- Zero emissions: When used as fuel, hydrogen produces only water vapor as a byproduct.
- Versatility: It can be used in various sectors, including transportation, industry, and power generation.
- Energy storage: Hydrogen can store excess renewable energy for later use, addressing intermittency issues.
- Decarbonization potential: It can help reduce emissions in hard-to-abate sectors like steel production and long-haul transportation[5].
Relevance to Human Survival
The development of green hydrogen technology is critical for the long-term survival and sustainability of human civilization[4]:
- Climate change mitigation: By replacing fossil fuels, green hydrogen can significantly reduce greenhouse gas emissions.
- Energy security: It provides a renewable and potentially abundant energy source, reducing dependence on finite fossil fuel reserves.
- Economic opportunities: The emerging hydrogen economy could create new jobs and industries.
- Improved air quality: Widespread adoption of hydrogen fuel could lead to cleaner air in urban areas, benefiting public health.
- Sustainable agriculture: Green hydrogen can be used to produce ammonia for fertilizers, ensuring food security without relying on fossil fuels[1].
Challenges and Future Outlook
Cost
Current production methods for green hydrogen are still more expensive than fossil fuel alternatives:
- The cost of producing green hydrogen ranges from $3 to $6.55 per kilogram, compared to $1.80 per kilogram for grey hydrogen produced from natural gas[9].
- Achieving cost parity with grey hydrogen requires renewable electricity prices to fall below $30 per megawatt-hour (MWh) and electrolyzer costs to decrease by 50%[13].
- Experts project that green hydrogen costs could fall 40-80% by 2030 as technology improves and production scales up[13].
Infrastructure
Significant investment is needed to develop hydrogen production, storage, and distribution systems:
- The global investment required for hydrogen infrastructure is estimated at $300 billion through 2030[13].
- Building a nationwide hydrogen fueling network in the U.S. could cost $35-65 billion over the next decade[10].
- Hydrogen storage facilities may require $637 billion in investment by 2050 to meet projected demand[11].
Efficiency
Further improvements in electrolysis and fuel cell technologies are required to increase overall system efficiency:
- Current electrolyzers operate at 60-80% efficiency, with a target of reaching 85-90% efficiency by 2030[9].
- Fuel cells for vehicles are about 60% efficient, compared to 25-35% for internal combustion engines[13].
- The overall efficiency of using green hydrogen in fuel cell electric vehicles is around 30%, versus 70-80% for battery electric vehicles[13].
These challenges highlight the need for continued research, development, and investment to make green hydrogen a viable and competitive clean energy solution. However, with projected cost reductions and efficiency improvements, green hydrogen is expected to play a crucial role in decarbonizing hard-to-abate sectors in the coming decades.
However, with continued research and development, experts believe that green hydrogen could play a crucial role in achieving global decarbonization goals and ensuring a sustainable future for humanity[4][5].
Current Status of Hydrogen Technology
Green hydrogen technology has made significant progress since 2010:
- The global demand for green hydrogen is projected to reach 530 million tonnes by 2050, potentially displacing 37% of pre-pandemic world oil production.
- As of 2022, global hydrogen use reached 95 metric tons, showing a 3% increase year-over-year.
- By 2030, low-emission hydrogen production could reach 38 metric tons to meet increasing demand.
Reasons for Perceived Slow Progress
While progress has been made, several factors contribute to the perception of slow advancement:
- Cost challenges: Green hydrogen production is still more expensive than fossil fuel alternatives. The cost at refueling stations in California at one point ranged from $13-$16 per kilogram.
- Infrastructure development: The lack of supporting infrastructure for storage and distribution has slowed widespread adoption.
- Production scaling: There are long lead times for making final investment decisions and challenges in securing financing and permitting for new production sites.
- Technological hurdles: Ongoing research is focused on improving electrolysis procedures, developing affordable fuel cells, and enhancing overall system efficiency.
Recent Innovations and Advancements
Despite challenges, there have been notable advancements:
- Electrolysis breakthroughs: New techniques, such as using light to activate water splitting, are making production more efficient and affordable.
- Fuel cell improvements: Advanced materials are being developed to increase conductivity and durability of polymer electrolytes.
- Integration with renewables: Combining hydrogen processes with solar and wind power is minimizing production emissions.
- Market growth: The low-carbon hydrogen market is projected to reach a valuation of US$130 billion by 2033.
While hydrogen technology has not yet surpassed all other technologies, it is making steady progress and is increasingly seen as a crucial component in the transition to a low-carbon energy system. The perceived slow progress is more a reflection of the complex challenges involved in scaling up a new energy technology rather than a lack of advancement.
