Biogas and hydrogen are both greenwashing products. Neither is better than electric alternatives where they are being sold. They have major major flaws that the fossil fuel industry (y’know, the one selling both of those products) won’t advertise to you:

• Biogas is derived from agricultural products. All the agricultural waste we produce can’t cover a meaningful part of even just our heating needs. This inevitably leads to a major misincentive to grow crops just to turn into methane, like we are doing with bioethanol, which has catastrophic land-use and environmental impacts.
• Hydrogen is very inefficient to produce. Most often produced with gas (lol), but even if produced through electrolysis it’s less efficient to have a double conversion than just use the electricity directly. It is also very hard to store/transport safely and efficiently.
• Regardless of any of the above, heat pumps have a COP of 3-5. A boiler has a COP of 1. I don’t care how clean your fuel is, it will always be more efficient to burn it in a regular power plant to power a heat pump than to burn it in a boiler.

And even if the above wasn’t true and biogas was awesome (it’s awful), the simple fact that they are selling trace amounts in order to promote fossil gas as their main product is an obvious act of greenwashing unto itself.

Greenpeace knows all of the above very well. I can’t say for sure that they are corrupt and bought out by the fossil fuel industry. All I can say is that I don’t have a better explanation for their stupidity.
