Tests in test laboratories have shown that up to 30 percent hydrogen admixture to natural gas is already possible. However, Viessmann is already thinking ahead to pave the way to a greenhouse gas-neutral future: gas heating appliances and fuel cells for 100 percent hydrogen operation are already in the development and test phase. They can be easily converted from natural gas operation - with high efficiency and completely no CO₂ / CO emissions in H₂ operation.
"H₂-ready" condensing boiler uses pure hydrogen
Viessmann is currently developing the "H₂-ready" condensing boiler, an innovative solution that can use pure hydrogen. The appliance is based on proven gas condensing technology and will also be able to run on natural gas or a natural gas/hydrogen mixture. System operators are thus independent in their choice of supplier and mixture. The first prototypes are currently being tested in detail at the Technikum, the research and development center at the company's headquarters in Allendorf (Eder). These devices are expected to be launched on the market from 2024, when the first gas networks for hydrogen will be available in Germany.
The innovative "H₂-ready" condensing boilers will be able to be converted from operation with natural gas or natural gas/hydrogen mixtures to operation with pure hydrogen in just a few simple steps. This ensures their future viability in the transition phase from natural gas to hydrogen. Further condensing systems, also for higher outputs, as well as fuel cells and combined heat and power plants for hydrogen are currently under development at Viessmann. As an innovation leader in the industry, the company will offer a complete portfolio for almost every application in the future.
Switching to sustainability
Numerous pilot projects for the use of pure hydrogen are already being supported, such as the construction of a hydrogen infrastructure in Kaisersesch, Rhineland-Palatinate. As part of the "SmartQuart" project funded by the BMWi, a complete hydrogen infrastructure is being created there by 2023 - from the generation of renewable electricity for operating the electrolysers, the storage of hydrogen and its distribution, to its use in the heat and power supply, industry and transport sectors. Viessmann has been involved in this first real laboratory of the energy transition from the very beginning and, in addition to condensing boilers for operation with pure hydrogen, will also test hydrogen-compatible fuel cell heating systems in practical operation in Kaisersesch.
In addition, our modular Vitomax industrial boiler program is already designed to be future-proof for the use of 100 percent hydrogen. It is suitable for use in the manufacturing industry, for example in the fertilizer, building materials, beverage, food, paper or chemical/pharmaceutical industries, but also in refineries or hospitals.
