The Future of Clean Energy: Green Hydrogen Through Electrolysis
Electrolysis, an innovative process enabling the splitting of water molecules into hydrogen and oxygen, is gaining momentum in the clean-energy sector. As nations prioritize decarbonization, billions are being invested into this technology to transform industries like steelmaking and oil refining.
According to the International Energy Agency, the global capacity for electrolysis is expected to skyrocket from nearly 3 gigawatts in 2023 to between 170 and 365 gigawatts by 2030. This surge is driven by the need to fulfill climate commitments, with proton-exchange membrane (PEM) electrolysers at the forefront of this green hydrogen revolution.
PEM electrolysers utilize a special membrane that efficiently separates gases during the electrolysis process. However, their performance is hindered by the corrosive conditions in which they operate. To overcome this, Toho Titanium has developed WEBTi™, an advanced material that significantly enhances the durability and efficiency of these electrolysers.
Featuring a unique porous structure, WEBTi™ optimizes gas and liquid transport while minimizing the use of valuable metals like platinum. With a thickness ranging from just 0.04 to 0.25 millimeters, WEBTi™ also fosters smoother surfaces, translating into more effective water-splitting reactions.
As the demand for clean hydrogen soars, Toho Titanium is racing towards the commercialization of WEBTi™, paving the way for a sustainable energy future powered by green hydrogen.
The Next Chapter in Clean Energy: Advancements in Green Hydrogen Technology
Electrolysis is poised to play a pivotal role in the transition towards a clean energy future, particularly through its ability to produce green hydrogen. As countries around the world commit to decarbonization, investments in electrolysis technology are surging, with implications for industries beyond just energy, such as steelmaking, transportation, and oil refining.
