據(jù)油價網(wǎng)休斯頓報道，由于全球液化天然氣需求在可預見的未來將繼續(xù)增加，供應“更綠色LNG”可能會讓生產(chǎn)商在這個蓬勃發(fā)展的市場上占據(jù)優(yōu)勢。法國油氣巨頭道達爾公司和德國西門子公司天然氣和電力部門時下正在合作進行研究，這兩家公司屆時都將從中受益匪淺。

減少LNG液化設施的溫室氣體排放，提高LNG液化廠可靠性、可維護性、遵守法規(guī)和減少開發(fā)成本是兩家公司這項研究的目標。隨著政府嚴格的法規(guī)和企業(yè)指令的出臺，脫碳LNG的生產(chǎn)可以滿足對這種燃料的更多需求。作為最清潔的化石燃料，歐盟委員會將其視為減少排放和應對氣候變化的極佳替代能源。

正如我們看到的綠色氫，一些國家已經(jīng)開始承諾投資數(shù)十億美元來應對氣候變化。為了實現(xiàn)這些目標，美國一直特別青睞LNG，這是因為美國國內(nèi)的天然氣供應充足，足以增加出口。

麥肯錫公司預測，到2035年底前，全球天然氣和LNG市場將繼續(xù)以每年3.6%的速度擴大。

法國能源巨頭道達爾公司近年來一直在擴大其能源投資組合，其中LNG被列為優(yōu)先項目。5月份，道達爾公司為莫桑比克的一個LNG項目籌集了150億美元，用于計劃在6月份的簽約。這個項目的投資額將擴大到230億美元，成為非洲迄今最大的私人投資，項目融資將與大約20家銀行綁定。這個項目將把天然氣冷卻成液體用于出口。

西門子公司看到了LNG的巨大潛力，并采取了另一個主要聯(lián)盟。西門子公司為巴西里約熱內(nèi)盧的綜合LNG發(fā)電項目新聯(lián)合循環(huán)發(fā)電廠找到了股權投資伙伴。西門子公司與巴西Prumo物流公司和石油巨頭英國石油公司各擁有項目公司Gas Natural Acu (GNA)的三分之一的股份。

西門子公司將受益于探索在滾動系統(tǒng)中燃氣輪機壓縮生產(chǎn)線的新研究。西門子公司旗下總部位于休斯頓的天然氣和電力部門生產(chǎn)用于發(fā)電的產(chǎn)品，如燃氣和蒸汽渦輪機、發(fā)電機、渦輪機組件和定制OEM電廠解決方案。

這項新研究將考慮使用燃氣輪機和電動驅(qū)動的壓縮生產(chǎn)線，結合已證明的單混合制冷和雙混合制冷技術，用于動力傳動系統(tǒng)和電力系統(tǒng)的冷卻功能。另一個正在探索的方法是開發(fā)旨在提高現(xiàn)場發(fā)電設施效率的技術；這可能包括熱回收系統(tǒng)、進氣口空氣冷卻、輔助燃燒、可再生能源整合和電池存儲。

西門子公司能源石油天然氣部門首席執(zhí)行官Thorbjoern Fors說：“該部門將通過應用久經(jīng)考驗的設備解決方案以及在項目的早期概念開發(fā)和前端工程設計時通過向客戶提供金融、技術開發(fā)和戰(zhàn)略支持來致力于支持LNG工業(yè)減少碳排放的努力?！薄拔覀兒茏院滥軌蚶^續(xù)與道達爾公司合作，努力實現(xiàn)LNG廠排放的最低水平，并實現(xiàn)LNG生產(chǎn)的最高可持續(xù)性?！?/span>

作為協(xié)議的一部分，西門子公司將在LNG廠設計中研究探索液化和發(fā)電的可能性。最終的目標是實現(xiàn)LNG的脫碳生產(chǎn)。但這兩家公司表示，其他效率也是總體目標的一部分。這將包括利用數(shù)字化和自動化平臺來優(yōu)化LNG廠設計，實現(xiàn)無縫項目執(zhí)行。

西門子公司認為，人工智能、數(shù)字雙胞胎和預測分析等數(shù)字技術的應用，為LNG開發(fā)商和運營商提供可觀的收益以及提高其設施的經(jīng)濟可行性。參與北極圈內(nèi)的哈默菲斯特LNG廠的西門子公司已經(jīng)能夠轉移LNG廠的計劃外停機時間。西門子公司開發(fā)了一種先進的數(shù)字系統(tǒng)，可以對整個系統(tǒng)進行監(jiān)控并迅速做出反應，以保證系統(tǒng)有效運行。

Energy Giants To Bring Greener LNG To The Market

As global LNG demand continues to grow into the foreseeable future, supplying ‘greener LNG’ could give producers an edge in this burgeoning market. French oil and gas giant Total and Siemens Gas and Power division are conducting studies that could greatly benefit each company.

Reducing greenhouse gas emissions at LNG liquefaction facilities, and improving plant reliability, maintainability, regulatory compliance and development costs, are targets for the study. Decarbonizing LNG production can feed into more demand for the fuel with stringent government regulations and corporate mandates kicking in. Being considered the cleanest fossil fuel, the European Commission sees it as an excellent alternative energy to reduce emissions and combat climate change.

As we’re seeing with green hydrogen, several countries have started committing billions of dollars in a bid to combat climate change. The US has been particularly fond of LNG to meet these targets — and as the domestic gas supply is ample enough to grow exports.

McKinsey & Co. forecasts that the global gas and LNG market will continue to expand 3.6 percent each year through 2035.

Total has been expanding its energy portfolio in recent years, with LNG being prioritized. Last month, Total was able to round up $15 billion for an LNG-project in Mozambique for a signing scheduled in June. It will be expanding to $23 billion and make up Africa’s largest private investment yet, binding in about 20 banks. The project will chill natural gas into a liquid for export.

Siemens sees great potential in LNG, having taken on another major alliance. The company found equity investment partners for a new combined cycle power plant for the integrated LNG-to-Power project in Rio de Janeiro, Brazil. Siemens owns one-third of project company Gás Natural A?u (GNA) with Brazil logistics company Prumo Logística S.A. and oil major BP.

Siemens will benefit from the new study’s exploration of gas turbine compression trains in rolling systems. Its Houston-based Gas and Power unit produces products for power generation, such as gas and steam turbines, generators, turbine packages, and tailored OEM power plant solutions.

The new study will look into using gas turbine- and electric-driven compression trains in conjunction with proven single-mixed refrigerant and double-mixed refrigerant technologies for the coolant function in drivetrain and power systems. Another method being explored is developing techniques to improve the efficiency of onsite power generation facilities; that might include heat recovery systems, inlet air chilling, supplementary firing, renewables integration, and battery storage.

“Siemens Gas and Power is committed to supporting the LNG industry’s efforts to reduce carbon emissions through the application of proven equipment solutions and by providing financial, technical development, and strategic support to customers in the early concept development and pre-front-end engineering design (FEED) stages of projects,” said Thorbjoern Fors, CEO for Siemens Energy Oil & Gas Division. “We are proud to continue these efforts by partnering with Total to drive towards the lowest possible plant emissions profile and attain the highest degree of sustainability in LNG production.”

As part of the agreement, Siemens in conducting studies to explore possible liquefaction and power generation in plant designs. The endgame here will be hitting targets for decarbonizing LNG production. But other efficiencies are part of the overall goals, according to the two companies. That will include leveraging digitalization and automation platforms to optimize plant design and achieve seamless project execution.

Siemens thinks that application of digital technologies, such as artificial intelligence, digital twins, and predictive analytics, offer substantial gains for LNG developers and operators to improve the economic viability of their facilities. Participating in the Hammerfest LNG plant above the Arctic Circle, Siemens has been able to divert unplanned downtime in the plant. Siemens developed an advanced digital system that monitors and rapidly responds to the entire system to keep it operating efficiently.
