在本文中，生物能源技术(BOT)被认为是替代化石燃料或传统(效率较低的)生物质能源系统的潜在碳减排机会。将赌注的能源成本(生产或节省)与化石燃料和传统生物质能源系统进行比较，以估计增量成本(IC)。使用通过替代化石燃料和传统生物质替代品获得的碳排放量(tCkWh−1或tCGJ−1)来估算每个选定赌注($kWh−1或$GJ−1)的碳减排IC。对替代传统技术的十种押注组合(有七种技术选择)的减排成本进行了估计和比较。分析表明，在10个项目案例中，6个项目的负IC在−37至−688$tC−1的范围内，4个项目的正IC在52-162美元tC−1的缓解范围内。负IC表明，建议的替代技术比原始技术更便宜。因此，结果表明，选定的赌注是具有成本效益的缓解机会，目前是清洁发展机制下的积极候选者。
In this paper, bioenergy technologies (BETs) are presented as potential carbon abatement opportunities substituting fossil fuel or traditional (less efficient) biomass energy systems. Cost of energy (produced or saved) of BETs is compared with fossil fuel and traditional biomass energy systems to estimate the incremental cost (IC). The IC of carbon abatement for each of the selected BETs (in $kWh−1or $GJ−1) is estimated using the carbon emission (tCkWh−1or tCGJ−1) reduction obtained by substituting fossil fuel and traditional biomass alternatives. The abatement costs are estimated and compared for ten combinations of BETs (with seven technology alternatives) substituting conventional technologies. The analysis indicates that out of the ten project cases six have negative ICs in the range of −37 to −688 $tC−1and four have positive ICs in the range of 52–162 $tC−1mitigation. The negative ICs indicate that the suggested alternatives are cheaper than the original technologies. Thus, results indicate that the chosen BETs are cost-effective mitigation opportunities and are currently aggressive candidates under Clean Development Mechanism.
