If that biogas was a practical substitute for petroleum it would still be
widely used. It can't be anywhere near as efficient as refined petroleum,
plus it takes energy to make biogas, which further lowers the throughput
efficiency. It's been around since before WW II
Producer gas has been around since the late 1700s when it was made from coal and used for street lighting in major European cities. The first internal combustion engines of the early 1800s used producer gas. The residue from production became the basis of the huge German Chemical industry and lead to the significant reduction in price of war materials and chemical fertilizers. As a result of that we can drop millions of tons of bombs on the land and cover the entire planet with chemical fertilizers. The old ways were much better.
