据油气新闻4月21日消息称，美国两家最大的石油公司正在对可再生汽油混合物进行道路测试，他们表示，这种汽油混合物可以将传统汽车的排放降低到与电动汽车竞争的水平。
雪佛龙和埃克森美孚正在推广的这种燃料，如果投入商业使用，可能会延长汽油市场的寿命，成为全球向更清洁燃料和电动汽车过渡的一部分。
雪佛龙美洲产品部总裁安迪·沃尔兹(Andy Walz)在周三的一次道路测试中表示：“我们真的相信，轻型汽车肯定会有替代品。电气化不是唯一的答案。”
在过去的几天里，雪佛龙和埃克森美孚公布了与汽车制造商丰田汽车公司合作使用部分由大豆或其他非化石原料制成的可再生汽油的测试结果。这些石油巨头说，美国现有的车队和加油站都可以使用这种混合物。
埃克森美孚表示，将这些可再生汽油混合物的成本降至可承受的水平，将取决于政府的支持性政策。雪佛龙补充说，这种可再生燃料可能需要数年时间才能投入使用。
“我们认为，它将需要政府的帮助来启动和运行，并扩大规模”，Walz说，他指的是为生物柴油和可再生柴油提供的现有激励措施。
雪佛龙负责战略和可持续发展的副总裁Balaji Krishnamurthy表示，扩大可再生汽油规模的最有效方式是通过碳定价，但并非所有司法管辖区都做好了准备。
两家公司使用不同的指标来衡量排放量。埃克森美孚表示，与传统汽油相比，其可再生汽油在生命周期内可减少高达75%的排放。雪佛龙表示，其混合汽油的碳密度比传统汽油低40%以上，包括汽车生产过程中的碳强度。

Chevron, Exxon pursue cleaner gasoline as alternative to EVs
The two largest U.S. oil companies are road testing renewable gasoline blends that they say could bring down emissions from conventional autos to levels competitive with electric vehicles (EVs).
The fuels being promoted by Chevron Corp (NYSE:CVX) and Exxon Mobil Corp (NYSE:XOM), if made commercially available, potentially would extend the life of the gasoline market as part of the world’s transition to cleaner fuels and electric vehicles.
“We really believe there has to be alternatives for the light duty vehicle,” Chevron President of Americas Products Andy Walz said at an event on Wednesday to road test the fuel. “Electrification is not the only answer.”
Chevron and Exxon disclosed in the past days test results from partnerships with automaker Toyota Motor (NYSE:TM) Corp using renewable gasoline partially made from soybeans or other non-fossil feedstocks. The blends could be used by the existing U.S. car fleet and gas stations, the oil majors have said.
Bringing the cost of these renewable gasoline blends to affordable levels would depend on supportive government policies, Exxon said. Chevron added it could be years before the renewable fuel could be available in pumps.
“We believe it is going to need government help to get up and running, and get scale,” Walz said, referring to existing incentives such as those provided for biodiesel and renewable diesel.
The most efficient way to bring scale to renewable gasoline would be through a carbon price, but not all jurisdictions are ready for it, said Balaji Krishnamurthy, Chevron’s vice president of strategy and sustainability.
The companies use different metrics to measure emissions. Exxon said its renewable gasoline could reduce emissions by as much as 75% compared to conventional gasoline on a life cycle basis. Chevron said its blend was more than 40% less carbon intensive than traditional gasoline, including the carbon intensity of manufacturing the vehicle.
