Provaris: Benefits of H2 Compression

Other Hydrogen Carriers

There are several other promising hydrogen carriers being explored. Here are a few:

Ammonia: Ammonia is a promising hydrogen carrier due to its high hydrogen density and ease of liquefaction1. It can be easily transported and stored, and the infrastructure for its handling is well established. However, the challenge lies in the safe and efficient release of hydrogen from ammonia.
Methanol: Methanol is another potential hydrogen carrier. It is a liquid at room temperature, making it easy to transport and store1. However, similar to ammonia, releasing hydrogen from methanol requires a catalyst and can produce carbon dioxide as a byproduct.
Formic Acid: Formic acid can also be used as a hydrogen carrier1. It can release hydrogen through catalytic decomposition. However, formic acid is corrosive and requires careful handling.
Liquid Organic Hydrogen Carriers (LOHCs): LOHCs are organic compounds that can reversibly bind hydrogen23. They are stable and non-toxic, and can be transported using existing infrastructure. However, the hydrogen release process requires a catalyst and can be energy-intensive2.
Metal Hydrides: Metal hydrides can absorb and release hydrogen through a reversible chemical reaction14. They can store a large amount of hydrogen and release it at relatively low temperatures. However, they are often heavy and require high pressures for hydrogen absorption4.

Each of these carriers has its own advantages and challenges, and the choice of carrier would depend on the specific application and infrastructure available. Research is ongoing to improve these technologies and develop new ones.
