Need for Biogas (RNG)
- Clean renewable traffic fuel is needed for heavy traffic that cannot run on electricity: busses, trucks, ships
- Biogas (RNG) is stated to be carbon negative traffic fuel, not only carbon neutral (California Air Resources Board)
Approach
- Produce biogas from woody waste resources locally
- Refine biogas to high grade biomethane
- Use biomethane instead of CNG
- Solve waste biomass problem
- Solve renewable traffic fuel problem
Benefits
- Can provide locally biogas from different types of difficult waste biomass, such as dead trees, straw, nut hulls, food residues
- Biogas (RNG) can be replace fossil natural gas (CNG) which is currently already used in buses, trucks and ships
Competitors
- Biodiesel from edible resources
- Food resources should not be used as fuel
- Biodiesel from inedible resources
- Expensive, high cost and low efficiency process
- Biogas
- Other technologies cannot produce biogas from woody biomass by anaerobic digestion
