Green Hydrogen and Electrolysis – For Net-Zero Emissions

Green Hydrogen and Electrolysis – For Net-Zero Emissions

Here’s an article posted in Matthey that talks about the power of Hydrogen and electrolysis for net-zero emissions.

Here are the key takeaways from the article on electrolyser technologies on the Johnson Matthey website:

• Different electrolyser technologies are necessary to cater to a variety of applications and emerging needs in hydrogen production.
• The four main types of electrolyser technologies are Liquid alkaline (AEL), Proton exchange membrane (PEM), Anion exchange membrane (AEM), and Solid oxide (SOEC), each with unique advantages and operational characteristics.
• It is important to consider trade-offs such as efficiency, cost (both capital and operating), and system durability when choosing the right technology for a specific application.
• The development of various technologies in parallel will support a diverse and resilient hydrogen production ecosystem as demand for green hydrogen increases globally.

Some of the interesting questions we have regarding this stuff:

1. What are the key trade-offs to consider when choosing among the four main types of electrolyser technologies (AEL, PEM, AEM, and SOEC)?
2. How do the intermittent nature of renewable energy sources impact the efficiency and suitability of different electrolyser technologies?
3. What are the implications of the U.S. Inflation Reduction Act on the development and expansion of green hydrogen production capabilities?
