A greener world with green hydrogen

Green hydrogen, produced by using renewable energy sources, is gaining momentum as a clean burning fuel with the potential to transform the energy landscape.

Japanese manufacturers, including Toshiba, Toray Industries and Panasonic are developing cutting-edge technologies to produce cheaper “green hydrogen”.

Making hydrogen a more accessible and environmentally friendly fuel option is set to revolutionize the energy industry.

Japan is poised to play a crucial role in driving the adoption of green hydrogen worldwide.

Toshiba’s Breakthrough in Iridium Reduction

Toshiba has made significant step in reducing the reliance on iridium, a rare and costly metal used in PEM (Proton Exchange Membrane) electrolyzers.

By creating an iridium oxide nanosheet catalyst, Toshiba has successfully reduced iridium content by nine-tenths while maintaining the same output and durability.

This breakthrough paves the way for the production of cheaper green hydrogen, as the cost associated with iridium is a major limiting factor.

Toshiba is ready to commercialize this technology, offering a promising solution to meet Japan’s goal of reducing hydrogen supply costs by 2050.

Toray Industries Enhanced Electrolyte Membrane

Toray Industries has focused on developing a more efficient and durable electrolyte membrane for PEM electrolyzers.

By utilizing hydrocarbons instead of fluoride, the company has achieved a higher performing membrane that is four times stronger. This advancement not only improves the production efficiency of green hydrogen but also significantly lowers the overall cost.

Through partnership with companies like Siemens Energy, Toray Industries aims to conduct field tests and release products with the new membrane in the coming years, propelling the adoption of green hydrogen on a global scale.

Panasonic’s Innovation in Alkaline Electrolyzers

Panasonic has taken a different approach by focusing on alkaline electrolyzers, which offer cost advantages by eliminating the need for expensive metals like iridium.

The company has successfully increased hydrogen production efficiency by reducing the size of affordable metals such as nickel and iron, creating a catalyst at the nanometer scale.

Alkaline electrolyzers have certain limitations in terms of durability when used with renewable energy, Panasonic is actively collaborating with water electrolier manufactures to further refine this technology.

This innovation has the potential to surpass PEM electrolyzers in terms of production efficiency, making green hydrogen production more accessible and cost-effective.

Next-Generation Technologies and the Future of Green Hydrogen

Beyond the current advancements in PEM and alkaline electrolyzers, the development of next generation technologies is underway.

Solid oxide electrolyzers, capable of producing hydrogen from steam at high temperatures of 600 to 800 degrees Celsius.

These electrolyzers offer increased efficiency, up to 20% more than other types, due to the ease of splitting water at higher temperatures.

Major players like Denso are actively involved in the development of solid oxide electrolyzer technology, further expanding the possibilities for cost effective and sustainable green hydrogen production.

States in the USA, including California and Hawaii are demonstrating an unwavering commitment to promoting and advancing the adoption of green hydrogen.

These states are at the forefront of the clean energy revolution, leading the charge towards a more sustainable future.

California has consistently positioned itself as a trailblazer in the clean energy transition, and green hydrogen is no exception.

To drive the growth of green hydrogen, California has implemented various initiatives. The state government has set ambitious targets for the distribution of hydrogen refueling infrastructure, aiming to establish 200 hydrogen refueling stations by 2025.

California has been actively investing in research and development projects focused on green hydrogen production.

These initiatives aim to explore innovative technologies, advance the efficiency of electrolysis processes and reduce the cost of green hydrogen production.

By fostering a supportive ecosystem for green hydrogen, California is creating a conductive environment for private sector investments and partnerships.

Hawaii, known for its fresh natural beauty and commitment to sustainability, is making remarkable steps in promoting green hydrogen.

Hawaii is taking bold steps to decrease its reliance on fossil fuels by placing a strong emphasis on green hydrogen as part of its renewable energy strategy.

The state is actively competing with numerous regions for federal funding through the U.S. Department of Energy’s Regional Clean Hydrogen Hub program.

The state has already witnessed the presence of hydrogen cars on its roads for several years, with the big island introducing hydrogen fuel cell electric buses on select routes last year.

The potential for growth in the green hydrogen sector has attracted the attention of clean energy companies.

AES Corp, currently the state’s largest solar producer, has expressed its interest in establishing a green hydrogen production center, recognizing the global significance for hydrogen as a fuel during the transition to renewable energy sources.

Green hydrogen, produced by extracting hydrogen from water using renewable energy sources like the sun, wind or geothermal power has the advantage of easy transport between islands through storage in canisters and tanks.
