雪佛龙正大力实施将牛粪转化为可再生天然气计划

据钻机地带10月8日彭博社报道，雪佛龙公司正大力实施将牛粪转化为可再生天然气的计划。

这家石油巨头与废物解决方案管理公司Brightmark LLC成立了一家合资企业，在多个州建设生物甲烷项目，这标志着该公司第二次尝试利用乳制品废物生产可再生天然气。根据一份电子邮件声明，雪佛龙计划随后购买这种生物甲烷，为目前使用压缩天然气的卡车、公共汽车和其他车辆提供动力。

雪佛龙公司美洲产品总裁安迪·沃尔兹（Andy Walz）在电话采访中表示，我们认为，这是我们在未来获得低碳燃料的部分途径。他称，最终目标是降低排放。

目前，化石燃料生产商正面临越来越大的压力，要求它们提高温室气体排放的透明度，并帮助应对气候变化。埃克森美孚周一受到审查，此前泄露的文件显示，该公司在公开宣扬其削减碳足迹计划的同时，却秘密计划增加碳排放。

雪佛龙将其生物乙烷投资描述为降低甲烷排放努力的一部分，但拒绝对项目的排放影响进行量化。

Brightmark首席执行官Bob Powell表示，该合资企业最初可能在纽约、密歇根、南达科他州和佛罗里达开发项目，其中大部分将用于加州的交通运输业。

雪佛龙与加州生物能源公司有另一家RNG合资企业。

Chevron Doubles Down on Renewable Natural Gas

Chevron Corp. is doubling down on its plan to turn cow manure into renewable natural gas.

The oil major formed a joint venture with waste solutions manager Brightmark LLC to build biomethane projects in multiple states, marking its second foray into producing renewable gas from dairy waste. Chevron plans to then buy the biomethane to power its trucks, buses and other vehicles currently running on compressed natural gas, according to an emailed statement.

“We think this is part of the way we are going to have lower carbon fuel in the future,” Andy Walz, president of Americas products at Chevron, said in a telephone interview. The ultimate goal, he said, is to lower its emissions.

The push comes as fossil-fuel producers are under mounting pressure to be more transparent about their greenhouse gas emissions and to help combat climate change. Exxon Mobil Corp. came under scrutiny Monday after leaked documents revealed the company secretly planned to increase emissions even as it publicly touted its plans for cutting its carbon footprint.

Chevron characterized its bioethane investments as part of an effort to lower methane emissions, but declined to quantify the emissions impact of the projects.

The joint venture may initially develop projects in New York, Michigan, South Dakota and down to Florida and most of it will be used in California’s transportation sector, said Brightmark Chief Executive Officer Bob Powell.

Chevron has another RNG venture with California Bioenergy.
