WM:天然氣和LNG將在凈零排放世界發(fā)揮重要作用

據(jù)美國(guó)鉆井網(wǎng)站2022年9月22日?qǐng)?bào)道,全球領(lǐng)先的商業(yè)情報(bào)公司伍德麥肯茲公司(WM)認(rèn)為,天然氣和液化天然氣(LNG)將在2050年前實(shí)現(xiàn)全球氣溫上升1.5攝氏度的目標(biāo)方面發(fā)揮重要作用,但由此產(chǎn)生的市場(chǎng)可能面目全非。 

加速能源轉(zhuǎn)型情景(AET-1.5)探索了一條路徑,即到本世紀(jì)末,全球氣溫自前工業(yè)化時(shí)代以來(lái)的升幅控制在1.5攝氏度以內(nèi),到2050年前達(dá)到全球凈零排放。根據(jù)AET-1.5,除天然氣外,其他碳?xì)浠衔镄枨髮⒀杆傧陆怠?nbsp; 

雖然脫碳措施無(wú)疑會(huì)給最終用途能源需求帶來(lái)壓力,但天然氣仍可發(fā)揮關(guān)鍵作用。煤炭的逐步淘汰支持了天然氣的使用,同時(shí)天然氣作為藍(lán)色氫氣的原料的需求也在不斷增長(zhǎng)。而且,至關(guān)重要的是,隨著電氣化和可再生能源的普及,天然氣與碳捕獲和儲(chǔ)存(CCS)相結(jié)合可以成為靈活和可調(diào)度發(fā)電的來(lái)源——即使電池技術(shù)正在進(jìn)步。 

然而,伍德麥克公司認(rèn)為,只有CCS技術(shù)得到改進(jìn),才能找到一種高效、低成本的減少二氧化碳排放的方法。 

由于歐洲從產(chǎn)能大國(guó)天然氣轉(zhuǎn)向,短期內(nèi)仍需要天然氣和液化天然氣投資。地緣政治沖突引發(fā)了全球天然氣市場(chǎng)的巨大變化——其中很大一部分是不可逆轉(zhuǎn)的。 歐洲對(duì)LNG的需求尤其飆升。

然而,大量已經(jīng)開(kāi)始并可能持續(xù)到明年的最終投資決定(FID)將迅速填補(bǔ)這一空間。在去年批準(zhǔn)5000萬(wàn)噸/年的新產(chǎn)能后,F(xiàn)ID的勢(shì)頭仍在繼續(xù)。到目前為止,今年1300萬(wàn)噸/年的普拉克明項(xiàng)目的第一階段和兩個(gè)快速LNG項(xiàng)目已經(jīng)獲得批準(zhǔn)。 

今年晚些時(shí)候,在美國(guó),伍德麥肯茲公司預(yù)計(jì)普拉克明項(xiàng)目的第二階段和切尼爾能源公司的科珀斯克里斯蒂項(xiàng)目第三階段將緊隨其后投產(chǎn)。在AET-1.5情景下,這些新投產(chǎn)項(xiàng)目加上卡塔爾的持續(xù)擴(kuò)張LNG產(chǎn)能,從而增加了21世紀(jì)20年代末或30年代初供應(yīng)過(guò)剩的風(fēng)險(xiǎn)。此后,隨著亞洲需求繼續(xù)增長(zhǎng),但將受到天然氣需求長(zhǎng)期下降的限制,機(jī)會(huì)之窗將再次打開(kāi)。

長(zhǎng)期來(lái)看,如果全球氣溫上升1.5攝氏度,天然氣需求下降是不可避免的。隨著氫、氨等綠色脫碳商品的大規(guī)模進(jìn)入,市場(chǎng)競(jìng)爭(zhēng)將更加激烈和充滿活力。

價(jià)格下跌和需求不確定性將不可避免地影響對(duì)大型固定基礎(chǔ)設(shè)施項(xiàng)目的數(shù)十億美元投資,比如新的大型國(guó)際管道。低油價(jià)還將挑戰(zhàn)高成本非常規(guī)油氣上游開(kāi)發(fā)的經(jīng)濟(jì)效益,降低進(jìn)一步勘探的意愿。由于市場(chǎng)收縮速度相比資產(chǎn)利用時(shí)間更快, 現(xiàn)有的基礎(chǔ)設(shè)施資產(chǎn)可能得不到充分利用。

Gas And LNG Have A Role To Play In Net-Zero World

Gas and LNG have an important role to play in realizing a 1.5-degree scenario by 2050 – but the resulting market could be unrecognizable, Wood Mackenzie believes.

An accelerated energy transition scenario (AET-1.5) explores a pathway on which the rise in global temperatures since pre-industrial times is limited to 1.5 °C by the end of this century and reach global net-zero by 2050. Under AET-1.5, hydrocarbon demand declines rapidly, except for natural gas.

While decarbonization measures undoubtedly put pressure on end-use energy demand, gas still has a crucial role to play. The phase-out of coal supports gas, and there’s also a growing need for gas as a feedstock for blue hydrogen. And, crucially, with widespread electrification and buildout of renewables, gas paired with carbon capture and storage (CCS) can be a source of flexibility and dispatchable generation – even as battery technology is advancing.

However, Woodmac believes that this is only possible if CCS technology improves, allowing for an efficient, low-cost method of reducing emissions from gas.

Near-term gas and LNG investment is still needed as Europe pivots from the larger producer's gas. The war sparked a massive shift in the global gas market – much of it irreversible. Demand for LNG in Europe in particular has soared.

However, a raft of FIDs, which has already begun and is likely to continue into the next year, will fill up this space quickly. FID momentum has continued after the 50 mmtpa of new capacity was sanctioned in 2021. 

Later this year, in the U.S., Woodmac expects the second phase of Plaquemines and Cheniere’s Corpus Christi Stage 3 to follow, amongst others. This activity – coupled with continued expansion in Qatar – increases the risk of oversupply in the late-2020s or early-2030s in an AET-1.5 scenario. The window of opportunity will open again after that as Asian demand continues to grow but will be limited by long-term gas demand reduction.

Longer term gas demand decline is unavoidable in a 1.5-degree pathway. And the market could become more competitive and dynamic as green commodities for decarbonization, such as hydrogen and ammonia, enter the market in big way.  

Inevitably lower prices and demand uncertainty would impact multi-billion-dollar investments into major fixed infrastructure projects – such as new large-scale international pipelines. Low prices would also challenge the economics of high-cost unconventional upstream developments and reduce the appetite for further exploration. Existing infrastructure assets may go underutilized as the market contracts faster than some assets reach the end of their lives.
