The feed-in of biogas methane to the natural gas Grid
Biogas can be upgraded to biomethane and injected into a gas grid. The feeding of biogas into the natural gas grid is an efficient energy solution, even if the sites in which the gas is to be applied are far away from the sites at which it is produced. Gas feed-in is facilitated via a compressor, a device raising the pressure level of the biomethane to that of the gas in the closed pressurised lines of the Grid. This can be the national high pressure gas transmission Grid or a local low pressure gas distribution network. To be used in the gas Grid, the biogas needs to cleaned of impurities, dried and upgraded to a higher methane content (> 95%) so that it resembles the qualities of natural gas. This approach is already being used in many countries including Germany, France, Austria and the USA.
Alfagy beats the competition's Operating Expenditure
Our injection plant is the product of more than 40 years of know-how applied in a cost effective manner to optimise gas production. As of date of publication, our Nm³ produced costs less than half of the competition with little or no maintenance. Other benefits are:
- Completely dry process = Robust process control, high availability and no biologic or chemical risk
- Unlimited adsorbent lifetime = Low maintenance cost
- Energy demand 0.15 kWh/Nm³ feed gas = Low operation cost
- Availability at 99% = Proven at our plant in Germany (30,000+ operating hours)
- Remote control and full-service = Operation of the plant without personal on site
- Product gas with 97% CH4 and drew point of -65°C = Reliable grid injection and no need to monitor the drew point
