Hydrogen Production - Sulfur-Iodine Thermochemical Process 

The sulfur-iodine thermochemical process, conceptualized over 30 years ago, is the most efficient process for producing hydrogen by splitting water. Developed by Gen. Atomics, this process allows for the production of hydrogen gas without use of fossil fuels (which is the major drawback to producing hydrogen today). The sulfur-iodine thermochemical process requires heat and water as the only inputs and oxygen and hydrogen are the only output or products. All of the reagents are self contained within the process and recycled creating no waste. When combining this technology with solar or nuclear power as a heat source, it becomes a very attractive process for hydrogen production and an alternative to fossil fuels.

The problem with the sulfur-iodine thermochemical process historically, is this process requires extreme operating environments for the efficient production of hydrogen and therefore a variety of significant material challenges have been the barrier to making this process technically and economically feasible.  

The utilization of Tantaline materials has proven to be the key to making this unique clean energy technology possible and has been proven by Gen. Atomics and the Koren Institute of Energy Research.
