據土耳其新聞社3月22日消息稱，根據IEA周五發布的最新報告，全球的沼氣和生物甲烷供應可以滿足全球20%的天然氣需求，同時減少溫室氣體排放。

IEA解釋說，沼氣為社區提供了當地的能源和熱能，也為家庭提供了清潔的烹飪燃料

IEA表示：“現代社會和經濟產生的有機廢物越來越多，比如農業殘留物、食物垃圾和動物糞便，這些廢物可用于生產沼氣和生物甲烷，這些清潔能源對可持續發展具有多重潛在效益。”

它補充說，將沼氣升級為生物甲烷將帶來天然氣的所有能源系統效益，而不會產生相關的凈排放。

IEA執行董事Fatih Birol表示：“沼氣和生物甲烷可以在未來的可持續能源中發揮重要作用，但目前我們正在錯失減少浪費和減少排放的機會。”

他建議，各國政府的推動可以為沼氣和生物甲烷提供必要的動力，在能源、交通、農業和環境等領域帶來好處。

最大的前景在亞太地區，那里的天然氣需求和進口近年來迅速增長。盡管如此，報告說，北美、南美、歐洲和非洲也提供了重大機遇。

報告說：“認識到減少二氧化碳和甲烷排放的重要性對提高生物甲烷的成本競爭力大有幫助。”

Birol表示：“政府在尋求加速清潔能源轉型時，他們不應忘記生物甲烷和沼氣等低碳氣體的重要性。”他補充說，除其他好處外，沼氣和生物甲烷還為農村社區和工業參與能源部門的轉型提供了途徑。

World’s biogas supplies can meet 20% of world gas needs

The world's biogas and biomethane supplies could meet 20% of global gas demand while reducing greenhouse gas emissions, according to a recent report by the International Energy Agency (IEA) on Friday.

The IEA explained that biogas offers a local source of power and heat for communities, as well as clean cooking fuel for households

“Modern societies and economies produce increasing amounts of organic waste – such as agricultural residues, food waste and animal manure – that can be used to produce biogas and biomethane, clean energy sources with multiple potential benefits for sustainable development,” the IEA said.

It added that upgrading biogas to biomethane would bring all the energy system benefits of natural gas without the associated net emissions.

“Biogas and biomethane can play major roles in a sustainable energy future, but for the moment we’re missing out on this opportunity to cut waste and cut emissions,” said Fatih Birol, the IEA’s executive director.

He recommended that a push from governments could give biogas and biomethane the necessary momentum, with benefits across energy, transport, agriculture and the environment.

The greatest prospects are in the Asia-Pacific region, where the demand and imports of natural gas have risen rapidly in recent years. Nonetheless, North and South America, Europe, and Africa offer major opportunities also, the report said.

“Recognition of the importance of reduced carbon dioxide and methane emissions goes a long way in enhancing biomethane's cost-competitiveness,” it said.

“As governments seek to accelerate their clean energy transitions, they should not forget the importance of low-carbon gases such as biomethane and biogas,” Birol said, adding that among other benefits, biogas and biomethane also offer a way to bring rural communities and industries into the transformation of the energy sector.
