Abstract
There is a lack of maturity with biomethane in catching up the fossil energy sources. The commercialization of biomethane needs an in-depth understanding of many factors via integrated systems analysis. Such analysis exponentiates our ability in overcoming the limitations of commercialization and helps us to leap forward in directions to replace conventional energy sources. This fundamental study focuses on integrative systems analysis, including factors such as technology, economics, environment, policy, social, and market in-depth to evaluate the challenges and remedial measures needed to improvise biomethane situations. This case study talks about the Irish biomethane industry, and the incentives needed to sustain it commercially. An in-depth analysis of the choice of feedstock and upgrading techniques, including carbon capture highlights the ease and difficulties of the workability of biomethane in Ireland. The scenarios included wastes from urban, rural, and coastal regions. Urban wastes needed high capital expenditure for upgrading. Water scrubbing, power to gas, and microalgae are the upgrading techniques considered in which water scrubbing has the maximum yield efficiency. Incentives needed for biomethane commercialization are in ranges between 0.13/m 3 and 1.03/m 3. Finally, an elaborate perspective outlines how integrative systems analysis helps to tackle the biomethane industry in Ireland and elsewhere.
