沼氣和生物甲烷可滿足世界20%的天然氣需求

據(jù)土耳其新聞社3月22日消息稱，根據(jù)IEA周五發(fā)布的最新報(bào)告，全球的沼氣和生物甲烷供應(yīng)可以滿足全球20%的天然氣需求，同時(shí)減少溫室氣體排放。

IEA解釋說(shuō)，沼氣為社區(qū)提供了當(dāng)?shù)氐哪茉春蜔崮?，也為家庭提供了清潔的烹飪?nèi)剂?/span>

IEA表示：“現(xiàn)代社會(huì)和經(jīng)濟(jì)產(chǎn)生的有機(jī)廢物越來(lái)越多，比如農(nóng)業(yè)殘留物、食物垃圾和動(dòng)物糞便，這些廢物可用于生產(chǎn)沼氣和生物甲烷，這些清潔能源對(duì)可持續(xù)發(fā)展具有多重潛在效益?！?/span>

它補(bǔ)充說(shuō)，將沼氣升級(jí)為生物甲烷將帶來(lái)天然氣的所有能源系統(tǒng)效益，而不會(huì)產(chǎn)生相關(guān)的凈排放。

IEA執(zhí)行董事Fatih Birol表示：“沼氣和生物甲烷可以在未來(lái)的可持續(xù)能源中發(fā)揮重要作用，但目前我們正在錯(cuò)失減少浪費(fèi)和減少排放的機(jī)會(huì)?！?/span>

他建議，各國(guó)政府的推動(dòng)可以為沼氣和生物甲烷提供必要的動(dòng)力，在能源、交通、農(nóng)業(yè)和環(huán)境等領(lǐng)域帶來(lái)好處。

最大的前景在亞太地區(qū)，那里的天然氣需求和進(jìn)口近年來(lái)迅速增長(zhǎng)。盡管如此，報(bào)告說(shuō)，北美、南美、歐洲和非洲也提供了重大機(jī)遇。

報(bào)告說(shuō)：“認(rèn)識(shí)到減少二氧化碳和甲烷排放的重要性對(duì)提高生物甲烷的成本競(jìng)爭(zhēng)力大有幫助?！?/span>

Birol表示：“政府在尋求加速清潔能源轉(zhuǎn)型時(shí)，他們不應(yīng)忘記生物甲烷和沼氣等低碳?xì)怏w的重要性?！彼a(bǔ)充說(shuō)，除其他好處外，沼氣和生物甲烷還為農(nóng)村社區(qū)和工業(yè)參與能源部門的轉(zhuǎn)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.
