天然气大国土库曼斯坦大力应对甲烷泄漏

土库曼斯坦的国有天然气生产商正计划招募专家帮助查明甲烷的泄漏情况,这是该国遏制强效温室气体排放的一项重大进展。


据知情人士透露,在2024年10月举行的土库曼斯坦石油和天然气会议上,土库曼斯坦天然气公司Turkmengaz表示其正在准备一份甲烷监测招标书,最快会在明年1月发布。


此次招标标志着土库曼斯坦在获取卫星数据领域的重大进展,并展现出其在甲烷泄露监测和修复领域的可能性。这也是土库曼斯坦、环保组织和包括美国在内的其他国家多年来应对甲烷泄露的成果。


在甲烷进入大气层后的头二十年里,它的温室气体效应至少是二氧化碳的80倍。国际能源署(IEA)最新的甲烷跟踪报告显示,人口稀少的土库曼斯坦是世界上天然气储量最大的国家之一,每单位产量油气排放的甲烷比任何其他主要供应国都要多。

自从在COP28宣布加入《全球甲烷承诺》,力争到2030年将甲烷排放量减少30%,土库曼斯坦仅用三年时间就削减了甲烷排放量,这对该国来说是一个了不起的转变。当时,土库曼斯坦的甲烷排放处于失控状态,大量气体从老化的能源基础设施和“地狱之门”——巨大的天然气坑泄漏到大气中。



甲烷承诺

最近几个月,土库曼斯坦及其国营能源公司制定了一份路线图,计划在2030年前至少减少三分之一的甲烷排放量。同时,该国正在推进制定有史以来的第一部旨在遏制甲烷排放的法规。


土库曼斯坦这一中亚国家的内阁通过了一份路线图,其外交部表示,该路线图将推动“能源基础设施实现彻底的现代化”,并将配以“其他适当措施”,以帮助实现甲烷减排承诺。


清洁空气工作组(Clean Air Task Force)甲烷污染预防全球总监Jonathan Banks说:“土库曼斯坦的集体行动和集体目标,应该被视为在这个希望稀缺的时代真正鼓舞人心的事情之一。”


但是,排放量不会立即下降,目前仍有许多工作处于起步阶段。未来几年里,土库曼斯坦需要资金、切实行动以及相关的技术专家资源,以支持该国应对巨大的甲烷排放问题。

但卫星观测结果表明,土库曼斯坦在减排方面已经取得了一些进展。根据环境监测公司Kayrros SAS 的数据分析,2020年至2023年期间,土库曼斯坦东部和西部盆地的排放量下降了约10%。这是该环境监测公司跟踪的13个化石燃料生产地区中降幅第二大的地区,仅次于澳大利亚的博文盆地(Bowen Basin)。

Turkmenistan’s Gas Company Will Enlist Experts to Combat Methane Leaks 


Turkmenistan’s state-owned gas producer is planning to enlist specialists to help pinpoint methane releases, a major advance in the nation’s efforts to curb emissions of the potent greenhouse gas.

Turkmengaz is working on issuing a tender seeking bids for methane surveillance in the coming months, and potentially as soon as January, according to people familiar with the matter. The plans were previewed at the Oil and Gas of Turkmenistan conference in October, they said, asking not to be named because the details are still being drafted.

The solicitation would mark a big push to acquire satellite data, and potentially even detect and fix releases of the planet-warming gas. It also represents action toward addressing methane leaks amid a years-long quest by the country, environmental groups and other nations, including the US, to stifle those emissions.

Methane is at least 80 times more powerful than carbon dioxide at warming the environment in the first two decades after it enters the atmosphere. Sparsely populated Turkmenistan sits atop one of the world’s largest natural gas reserves and spews more methane per unit of oil and gas output than any other major supplier, according to the International Energy Agency’s latest Methane Tracker report.

A call to the phone number listed on Turkmengaz’s website wasn’t answered and the company didn’t respond to an email seeking comment.

Cutting methane emissions would represent a remarkable shift for the country in just three years since the launch of a global pledge to slash spewing the gas by 30% by 2030. At the time, Turkmenistan’s emissions of the gas were spiraling out of control and into the atmosphere, leaking from aging energy infrastructure and one massive burning crater.

Methane Pledge

Last year Turkmenistan said it was signing on to the global methane pledge that now represents nearly 160 nations. In recent months, the country and its state-run energy companies have developed a road map for cutting at least a third of its methane emissions by the end of the decade. It is in the process of imposing its first-ever regulations to clamp down on the problem.

The Central Asian nation’s cabinet has adopted a road map that the foreign affairs ministry said would drive “radical modernization of energy infrastructure” and the implementation of “other appropriate measures” to help meet methane-cutting commitments.

“The collective actions and the collective goals that we are seeing coming out of Turkmenistan should be seen as one of those things that really gives people hope in a time where hope is not very prevalent,” said Jonathan Banks, global director of methane pollution prevention at the Clean Air Task Force.

To be sure, emissions will not fall immediately. Many of the efforts are still in their infancy, teeing up spending and action that is necessary to wrest control over the country’s massive methane problem in coming years. And once emissions are identified it will still require engineers in the field to replace equipment or make operational changes to halt the releases.

But satellite observations suggest there’s been some progress. Emissions in the nation’s eastern and western basins fell about 10% between 2020 and 2023, according to an analysis of the data by Kayrros SAS. That’s the second-biggest drop among 13 fossil fuel-producing regions tracked by the environmental monitoring company, only behind Australia’s Bowen Basin.
