據(jù)天然氣加工網(wǎng)站10月7日報(bào)道 石油巨頭雪佛龍的美國子公司和廢物管理公司Brightmark宣布稱，其已經(jīng)成立了一家合資企業(yè)，銷售乳制品生物甲烷氣，這是一種由牛打嗝產(chǎn)生的甲烷排放物制成的可再生天然氣。

反芻家畜，如牛和羊，在消化纖維植物材料的同時(shí)，會(huì)產(chǎn)生甲烷作為副產(chǎn)品。甲烷排放量占全球排放量的20%，科學(xué)家多年來一直致力于減少牛氣體排放量。

雪佛龍美國公司和Brightmark公司表示，他們在新合資企業(yè)Brightmark RNG將為美國多個(gè)州的乳制品生物甲烷氣項(xiàng)目的建設(shè)和商業(yè)運(yùn)營提供資金。

兩家公司表示，雪佛龍將購買合資公司項(xiàng)目生產(chǎn)的可再生天然氣，并將其銷售給使用壓縮天然氣的汽車。

這一最新舉措突顯出投資者需求的轉(zhuǎn)變，近年來，包括雪佛龍?jiān)趦?nèi)的化石燃料企業(yè)面臨著越來越大的壓力，要求它們減少排放，加大在低碳能源上的投入，并披露化石燃料生產(chǎn)對氣候變化的影響。

雪佛龍美洲產(chǎn)品部總裁安迪·沃爾茲表示：“我們正在增加可再生能源，以支持我們的業(yè)務(wù)，進(jìn)行有針對性的投資，并在評估新興能源及其在我們投資組合中的作用時(shí)建立伙伴關(guān)系。”

雪佛龍也是另一家可再生天然氣合資公司Calbigas LLC的一部分，該公司上個(gè)月宣布首次在Kern郡的奶牛場成功生產(chǎn)。

Chevron, Brightmark form JV for dairy biomethane fuel project

Oil major Chevron Corp's U.S. unit and waste management firm Brightmark LLC announced they have formed a joint venture to market dairy biomethane, a renewable natural gas made of methane emissions from cattle burps.

Ruminant livestock such as cattle and sheep produce methane as a byproduct while digesting fibrous plant material. Methane accounts for 20% of global emissions and scientists have been working for years to reduce the amount of the gas released by cattle.

Chevron U.S.A. and Brightmark LLC said their investments in the new venture, Brightmark RNG Holdings LLC, will fund the construction of required infrastructure and commercial operation of dairy biomethane projects across multiple U.S. states.

Chevron will purchase the renewable natural gas produced from the JV's projects and market it for use in vehicles that run on compressed natural gas, the companies said.

The latest move underscores a shift in investor demand, with increased pressure in recent years on fossil fuel companies, including Chevron, to reduce emissions, spend more on low-carbon energy and make disclosures on the impact of fossil fuel production on climate change.

"We are increasing renewables in support of our business, making targeted investments and establishing partnerships as we evaluate emerging sources of energy and the role they will play in our portfolio," said Andy Walz, president of Americas products for Chevron.

Chevron is also part of another renewable natural gas JV, CalBioGas LLC, that last month announced its first successful production from dairy farms in Kern County.
