???? 據道瓊斯3月5日消息，兩家與石油市場息息相關的公司和微軟計劃在加州開發一座發電廠，他們稱該發電廠的碳排放將為負值，這是大公司實驗新能源項目的最新案例。

????油田服務公司斯倫貝謝公司的子公司、雪佛龍公司和微軟周四表示，他們將在加州門多塔開設一座生物質發電廠，將農業廢棄物轉化為一種與氧氣結合后可產生電力的氣體。這三家公司在一份聲明中表示，專注于部署減少碳排放的能源開發項目的Clean Energy Systems也參與了這項合作。

????許多大公司一直在進軍可再生能源市場，有時是因為投資者擔心可持續性發展，有時是因為關注旨在限制導致氣候變化的碳排放的潛在新法規。例如，通用汽車公司表示，公司正在尋求與LG化學公司在美國合作開發第二家電池廠;埃克森美孚公司表示，它現在認為捕捉碳排放將是它的一個真正的商機。

????斯倫貝謝、雪佛龍和微軟周四表示，預計加州擬建生物質發電廠轉化產生的幾乎所有碳都將被捕獲并注入地下。

????他們表示，這一過程旨在產生凈負碳排放，有效地消除大氣中的溫室氣體。按年計算，該工廠預計每年將減少約30萬噸二氧化碳，相當于6.5萬個家庭用電所產生的排放量。

????斯倫貝謝、雪佛龍和其他參與該項目的公司計劃明年就建設該工廠做出最終投資決定。他們表示，之后他們將評估其他“擴大這一碳捕集和封存解決方案”的機會。

????Schlumberger, Chevron, Microsoft Eye Biomass Plant In California

????Two companies tied to the oil market and Microsoft Corp. plan to develop a power plant in California they say will produce a negative amount of carbon emissions, the latest example of big companies experimenting with new energy projects.

????A unit of oilfield services company Schlumberger Ltd., Chevron Corp. and Microsoft said Thursday they will open a bioenergy plant in Mendota, Calif., that converts agricultural waste such as almond trees into a gas that, when combined with oxygen, will generate electricity. Clean Energy Systems, which focuses on deploying energy developments that cut carbon, is also part of the effort, the companies said in a statement.

????Many large corporations have been moving into renewable energy markets, pushed at times by investors concerned about sustainability and with an eye on potential new regulations designed to limit carbon emissions that cause climate change. General Motors Co., for example, said Thursday it is looking to develop a second battery plant with LG Chem Ltd. in the U.S., while Exxon Mobil Corp. said Wednesday it now believes that capturing carbon emissions will be a real business opportunity for it.

????Virtually all of the carbon created from the conversion at the proposed California plant is expected to be captured and injected underground, the companies said Thursday.

????They said the process is designed to result in net-negative carbon emissions, effectively removing greenhouse gas from the atmosphere. On an annual basis, the plant is expected to remove about 300,000 tons of carbon dioxide annually, equivalent to the emissions from electricity use in some 65,000 homes.

????Schlumberger, Chevron and the other companies involved in the project plan to make a final investment decision about building the plant next year. Then, they said they would evaluate other opportunities to "scale this carbon capture and sequestration solution."
