Biogas:
Biogas history.
Over the recent years an important change has been produced concerning energetic conscience. This has happened as there is a need to use renewable energies because of its profitability but also because of its ecologic impact. Biogas has been consolidated as an important clean thermal and electric power resource. Nowadays biogas is widespread.
What is biogas?
Biogas is a gas produced from the microorganism’s action during a process of biodegradation of organic matter and other organic subproducts in anaerobic conditions (oxygen’s absence). This organic matter is made of animal’s feces matter and also from plant’s cultivation, or a combination of both matters. The organic matter is mixed with other organic subproducts and it is introduced inside cylindrical pools called digesters. Inside the digesters the process of controlled fermentations is carried out. From this process biogas will be obtained. Biogas is made of CH4, or what is the same, methane (60%- 70%), 30%- 40% of carbon dioxide (CO2), 1% of oxygen and small traces of other gases. The storage of this gas will be made in the digesters.
This gas will be the combustible for the cogeneration engine that will produce power through an alternator and thermal power, as a consequence of the refrigeration of this engine. The engine will heat the digesters and the rest will be used in the treatment process. Once the biogas is removed from the matter, the product will be stored in pools and subsequently the biogas will be applied as a fertilizer in the fields.
Thanks to the regulated rate, which allows economic viability in biogas plants, (RD 661/2007), installations are allowed to enter the free market. In this case the Cap&Floor system will be applied. By this, the maximum incomes will be limited and the minimum ones will be assured; the conditions will be modified according the following characteristics:
Economic Regime:
The Royal Decree RD 661/2007, allows the biogas installations to pay its own electric production, or depending on the rates that the electricity free market determines, or a fixed regulated rate. In the first case, the Cap&Floor system will be applied where the maximun incomes will be limited and the minimum ones will be assured. In the second case, a fixed price for the production will be perceived, which will be annually updated depending on the inflation.
Regulated rate:
| Plants with a power lower than 500kW | Plants with a power superior to 500kW | |
| Regular market |
First 15 years: 13.8262 c€/kWh
From 15 years on: 6.8872 c€/kWh |
First 15 years: 10.2409 c€/kWh
From 15 years on: 6.8872 c€/kWh |
| Reference rate | First 15 years: 10.8104 c€/kWh | First 15 years: 6.5870 c€/kWh |
AE3000 forecast
AE3000 plans to develop different biogas plant’s projects, nationally and internationally.
At the end of 2011, AE3000 will have more than 16MW installed in biogas plants.
We will try to be a referent executing these projects, nationally and internationally, in the renewable energies sector.
Collaborations
AE3000 collaborates with the business ECOBIOGAS, spacialised in the biogas field as in renewable energies.
