U.S. Navy Wants to Fuel Ships Using Seawater

The U.S. Navy’s Arleigh Burke-class destroyer typically burns 1,000 gallons of petroleum fuel an hour. Most of the Navy’s fleet shares the same ravenous appetite for fuel, and refueling these massive warships can interrupt missions and present challenges in rough weather. However, researchers at the U.S. Naval Research Laboratory have now proven that it’s possible to power engines instead with a cheap, convenient supply of fuel: seawater.
Scientists have spent nearly a decade laboring to turn the ocean into fuel. The breakthrough, demonstrated in a proof-of-concept test, was made possible by a specialized catalytic converter that transforms carbon dioxide and hydrogen from seawater into a liquid hydrocarbon fuel.
A Naval Milestone
The development of a liquid hydrocarbon fuel is being hailed as a game changer. If Navy ships create their own fuel they can remain operational 100 percent of the time, rather than conducting frequent fuel-ups with tankers while at sea, which can be tricky in rough weather.
A catalytic converter extracts carbon dioxide and hydrogen from water and converts the gases into liquid hydrocarbons at a 92 percent efficiency rate, and the resulting fuel can be used in ships’ existing engines.
The feasibility of the approach was demonstrated in the test on April 2, when researchers flew a model airplane using the fuel from seawater. “This is the first time technology of this nature has been demonstrated with the potential for transition, from the laboratory, to full-scale commercial implementation,” said Navy research chemist Heather Willauer in a news release Monday.
The next major step is to build the infrastructure to convert seawater into fuel on a massive scale. The Navy would first start mass-producing fuel in land-based operations, which would be the first step toward installing fuel generation systems on ships. The Navy predicts the seawater fuel would cost about $3-6 per gallon, and could be commercially viable within a decade.

嘩
唔撚係啩
唔撚係啩美軍宣稱已成功將“海水變燃油”

現代戰爭中,後勤補給的地位越來越重要,而對於需要在大洋上數個月連續作戰的遠洋艦隊而言,這個問題就更嚴重。僅是燃料補給就足以讓艦隊補給船疲於奔命。美國海軍近日宣布,他們終於解決了一個困擾科學家數十年的問題──將海水直接轉化為燃料。
讓軍艦擺脫對燃油的依賴
美軍目前只有航母和部分潛艇配備核動力裝置,其余艦艇則需要15艘補給艦運輸燃料,這給艦艇的行動能力帶來嚴重制約,同時產生巨大的運輸成本和環境風險。為了解決這一問題,美國海軍研究實驗室多年來致力於開發一項新技術,希望能讓軍艦擺脫對燃油的依賴,在能源問題上實現“自給自足”。
據法新社8日報道,負責此項研究的美軍中將菲利普‧庫倫近日宣布,研究取得了突破性進展。研究人員成功地從海水中提取出二氧化碳和氫氣,轉化為一種碳氫化合物液體燃料。庫倫稱:“我們之前一直認為,能源像空氣一樣,取之不盡用之不竭。然而這是一種錯誤的觀念,人類必須正視和解決能源問題。過去60年時間里,人類一直在尋找廉價的可持續能源。” 參與研究的海瑟‧魏勞爾博士表示,自己在“海水變燃油”項目上已經工作了近10年,對於最近的突破激動不已:“這是我們首次同時從海水中提取出二氧化碳和氫氣。”她介紹稱,這種新型燃料“不管是看起來還是聞上去”都和傳統燃料沒什麼不同。
艦船“自給自足”還需10年
目前,美國海軍研究實驗室的科學家已經用這種“海水燃料”,讓模型飛機飛上了天。
據他們估算,這種新型燃料的成本在1加崙(約等於3.78升)3到6美元之間。
下一步,科學家打算研究如何從定量海水中提取出更多的二氧化碳和氫氣。魏勞爾博士稱:“我們已經展示了可行性,接下來我們將研究如何提高轉化效率。”
對於軍方來說,新燃料帶來新思考。菲利普‧庫倫中將表示:“汽車開到加油站加油,海軍不同,我們的‘加油站’就是補給艦,它開過來給我們加油。”“如果美國的海軍艦艇能完全擺脫對燃油的依賴,在艦艇上自己生產‘海水燃料’,實現自給自足,這將從根本上改變美國海軍的行動能力和戰略思維。”
不過科學家指出,美軍艦艇要實現燃料“自給自足”,至少還需要10年時間。(據《新聞晨報》)
