Study on the wind/biogas integration system for power generation and gas supply

Abstract

In order to achieve the optimal overall utilization of biogas resources and wind energy, this paper proposes a wind/biogas integration system for power generation and gas supply. In the integration system, less wind power is used to heat the biogas pool to raise and keep the fermentation temperature, while most wind power combining with biogas power are directly supplied for users. The integration system overcomes the difficulties involving low fermentation temperature of biogas production and uncertainty and fluctuation of wind power in the large-scale utilization. By adopting the innovative technologies, including low-cost and high-efficiency fixed-pitch variable-speed wind turbine, high-efficiency biogas pool with heat pumps using wind power and integrative intelligent control system, it is expected to make 20~30% cost saving of wind power and 2 times increase of biogas output over conventional technologies. The integration system will independently provide a stable power source and daily gas for small towns, large-scale farms, remote areas, islands, farmers and villages, and it reveals a broad application prospect.

A Sustainable Business Framework Using Solar and Bio-Energy to Instate Incessant Power in Rural India: Optimal Scheduling, Smart Metering, and Economic Viability

“…. [2]- [15], [17]- [20], [22], [25], [40], [46] have stated to use biogas for power generation but that is either used as peak VOLUME y, xxxx power generation or as base power generation until the gas is fully utilised. Some of them used battery as backup power, which become expensive; while others don't have any plan for backup power.…”

A review of key points of an industrial biogas plant. A European perspective

“…Another interesting alternative use of biogas is as complement of other renewable sources of energy such as wind and solar plants. In periods of no wind, the production of a wind turbine could be replaced by the use of biogas guarantying the continuity of this integrated source of energy [17], [18].…”

Telemonitoring Temperature and Humidity at Bio-energy Process using Smart Phones

“…Methane potentially composes bio-energy which can be used to generate electricity and heat, or even transformed into other kind of energy. Temperature and relative humidity (RH) have an important role in biogas fermentation [2]. The potency analysis example of a biogas production with a case study in landfill Pontianak Indonesia can be seen in [3].…”
