沼氣是一種再生技術,可以作為化石燃料的替代品減少對環境的影響。然而,為了實現 IEA 的 NZE 目標,成長率需要大幅提高。
全球每年直接和間接產生超過 1050 億噸有機廢物,所有這些廢物分解後都會將有害的甲烷和其他溫室氣體直接釋放到空氣中。如今,此類廢棄物中只有 2% 得到處理和回收。這個比例只是沼氣和生物甲烷潛力的一小部分,根據 IEA 的數據,沼氣和生物甲烷可以滿足世界天然氣需求的 20%。沼氣和生物甲烷氣體是可再生能源,不僅可以減少未經處理的廢物的溫室氣體排放,還可以利用現有的天然氣基礎設施和管道將廢物轉化為能源。儘管沼氣市場前景穩定成長,但需要大幅加快成長步伐才能實現 IEA NZE 2030 年情境目標。為了實現這一目標,需要大幅增加政府的支持,以使對該技術的投資對私人投資者更具吸引力。沼氣和生物甲烷生產領先的地區和國家是歐洲,其次是美國和中國。新興經濟體顯示出成長潛力,實現 NZE 目標將取決於其對沼氣基礎設施的擴張和投資。一些石油和天然氣公司也在投資沼氣和生物甲烷技術。 TotalEnergies 是沼氣產業中合作最積極的石油和天然氣公司。
本報告調查了沼氣市場,並總結了沼氣技術概述、2040 年之前的市場前景以及各地區的最新趨勢。
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.
