Today, most stationary power systems run on natural gas. The idea of blending hydrogen into the gas pipeline network, however, has been under discussion for a while, and there have already been some tests conducted on its feasibility. Heating manufacturers have assured clients that current-generation systems can run on low-level 10 percent hydrogen blends and announced that the next generation could manage up to 30 percent. They said in the long term, it would also be possible to use hydrogen only. For example, Viessmann has announced that all of its new gas boilers would be “hydrogen-ready” starting in 2023 or 2024.
