沼气是一种再生技术,可以作为化石燃料的替代品减少对环境的影响。然而,为了实现 IEA 的 NZE 目标,成长率需要大幅提高。
全球每年直接和间接产生超过 1050 亿吨有机废物,所有这些废物分解后都会将有害的甲烷和其他温室气体直接释放到空气中。如今,此类废弃物中只有 2% 得到处理和回收。这个比例只是沼气和生物甲烷潜力的一小部分,根据 IEA 的数据,沼气和生物甲烷可以满足世界天然气需求的 20%。沼气和生物甲烷气体是可再生能源,不仅可以减少未经处理的废物的温室气体排放,还可以利用现有的天然气基础设施和管道将废物转化为能源。儘管沼气市场前景稳定成长,但需要大幅加快成长步伐才能实现 IEA NZE 2030 年情境目标。为了实现这一目标,需要大幅增加政府的支持,以使对该技术的投资对私人投资者更具吸引力。沼气和生物甲烷生产领先的地区和国家是欧洲,其次是美国和中国。新兴经济体显示出成长潜力,实现 NZE 目标将取决于其对沼气基础设施的扩张和投资。一些石油和天然气公司也在投资沼气和生物甲烷技术。 TotalEnergies 是沼气产业中合作最积极的石油和天然气公司。
本报告调查了沼气市场,并总结了沼气技术概述、2040 年之前的市场前景以及各地区的最新趋势。
Biogas is a renewable technology that can lessen the impact on the environment as an alternative to fossil fuels. However, its growth will need to increase drastically if it is to meet the IEA's NZE targets.
Humans, directly or indirectly, generate over 105B tonnes of organic waste globally each year, all of which release harmful methane and other GHG emissions directly into the atmosphere as they decompose. Today, only 2% of such waste is treated and recycled. This percentage only represents a fraction of the biogas and biomethane potential, which according to the IEA can supply 20% of worldwide gas demand. Biogas and biomethane are renewable energy technologies that can both reduce the GHG emissions from untreated waste, as well as turn waste into energy by using pre-existing natural gas infrastructure and pipelines. The market outlook for biogas shows steady growth, but in order to meet the IEA NZE Scenario 2030 targets, the growth pace will have to dramatically increase. This can only be achieved with much stronger government support, which needs to make investing in the technology more appealing to private investors. The regions and countries at the forefront of biogas and biomethane production are Europe, followed by the US and China. Developing economies are showing growth potential and the ability to reach NZE targets will hinge upon their expansion and investment in biogas infrastructure. Some oil and gas companies have also been investing in biogas and biomethane technologies. TotalEnergies stands out as the oil and gas company that has the most active partnerships in the biogas industry.
