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