biogas is flexible.
Ensuing client requirements and specifications biogas can be used to produce a variety of energies; the energy-mix depends on the industrial applications to be served as well as the local economics and prices of conventional energy markets.
Biogas is produced 24/7, it is storeable and operational for base load as well as peak load.
- Electricity: Biogas is used to produce electricity solely using a generator set. Electricity is used on site or injected to the grid.
- Combined heat and power (CHP) production: Biogas is burnt in a CHP gas engine that produces electricity and recyclable off-heat from engine, intercooler, oil, water and exhaust of 90°C up to 250°C. The heat can be used for industrial applications, district heating, etc.
- Tri-generation: Biogas is used to produce combined cooling, heat and power CCHP.
- Natural gas or heating oil replacement: Biogas can be directly fired in gas boilers/burners.
- Gas grid injection: Biogas, which basically consists of 55% – 65% methane and the rest largely carbon dioxide, is purified to 98% bio-methane gas; then injected into the natural gas grid.
- Vehicle fuel: Bio-methane can be used as fuel for gas adapted vehicles, as CNG or LNG. Some 50 – 100 models of natural gas vehicles NGVs, vans and busses are on the market.
- Compressed natural gas CNG: the purified bio-methane can be compressed to CNG for transport and storage, 205-275bar, at room temperature.
- Liquefied natural gas LNG: Bio-methane can be liquefied at very low temperatures, to a super-cooled (cryogenic, -260°C) LNG with a volume reduction of 1/600 facilitating transport and storage, pressure is comparably small at 3-10bar.
- Carbon dioxide scrubbing: carbon dioxide can be recovered from the exhaust gas to be used in industrial processes.
- Fuel cells; potential commercial use in future.
