Balancing with Biogas?
News that the peak market prices are getting out of hand in Poland raises the issue of using more means to balance energy production. The 24 hour cycle seems to be getting worse. Energy storage over a short span of hours seems to be an attractive idea. While there are a number of energy storage solutions using batteries to store electricity, or devices to store kinetic energy to produce electricity later, one of the renewable energy sources itself has the potential to provide output matched to the 24-hour demand cycle - biogas, All biogas plants have biogas storage in some form. The most common is shown below: One biogas vendor explained one of the advantages of gas storage: " Since the gas-store can hold several hours of gas, the CHP unit can be turned down during off-peak generating times without loss of biogas. The stored biogas can then be burned during high-peak electricity demand hours to maximize revenue efficiency. In addition, the gas store provides a steady s...
