ᐅ Gas heating systems

Has anyone here had experience with gas heating systems that also burn biogas?

Hello clamatthys,
Since 1997, there has been a commercial facility in Samstagern, Canton Zurich, that processes green waste from organic waste bins through anaerobic digestion. The gas produced is purified until it is chemically indistinguishable from natural gas, and then it is fed into the distribution network of the Zurich gas utility.

The raw biogas, which typically contains about 60 to 65 percent methane, coming from the digester must be upgraded to natural gas quality by removing moisture and hydrogen sulfide.

Upgraded biogas can be used easily with standard gas boilers, and producers feed it into the natural gas grid—so you wouldn’t notice any difference and can heat as usual.

Are you interested in producing biogas yourself for use in your own home?

Biogas plants are only environmentally sustainable with reservations. One condition, for example, is that the plant is well sealed so that no gas can escape. Furthermore, sufficient biomass must be locally available without extensive transportation...

Although this doesn’t directly answer the question, I recently read that wood pellets for heating are becoming very popular. The boilers designed for them are reportedly very expensive, but like solar systems, they are said to pay off after a few years. Especially since the pellets themselves are quite affordable. Plus, they are environmentally friendly... although gas also has some advantages.

I just wanted to briefly mention a good alternative to gas. Of course, everyone has to decide for themselves and their budget. 🙂
