据CNBC网站12月14日消息 根据协议，美国联合航空公司表示，预计将购买多达100台ZeroAvia ZA2000-RJ发动机，该发动机被称为零排放和100%氢电发动机。
该航空公司表示，该发动机预计将成对使用，作为现有支线飞机的新动力源。
联合航空表示，计划就其中50台发动机达成一项有条件的购买协议，另外还有50台发动机的选择权。该公司补充称，这项技术可能从2028年起改装至飞机上。
在周一发布的一份声明中，联合航空首席执行官斯科特·柯比表示，氢能发动机是小型飞机实现零排放航空旅行的最有希望的途径之一。
在另一份声明中，ZeroAvia表示已筹集到3500万美元的资金。除联合航空公司外，其他参与融资的公司还包括阿拉斯加航空集团，该集团的投资此前已宣布。
ZeroAvia表示，总共吸引了一系列利益相关者的1.15亿美元投资，其中包括壳牌风险投资公司、亚马逊气候承诺基金和Breakthrough能源风险投资公司。

United Airlines plans to purchase up to 100 hydrogen-electric engines
Under the deal, United said it expects to purchase up to 100 of ZeroAvia’s ZA2000-RJ — an engine it described as zero-emission and 100% hydrogen-electric.
The airline said the engine was “expected to be used in pairs as a new power source for existing regional aircraft.”
United said it plans to pursue a conditional purchase agreement for 50 of the engines, with an option for 50 more. The tech could be retrofitted to aircraft from 2028, it added.
In a statement issued Monday, United CEO Scott Kirby said hydrogen-electric engines were “one of the most promising paths to zero-emission air travel for smaller aircraft.”
In a separate announcement, ZeroAvia said it had raised $35 million in funding. Alongside United, others taking part in the funding round include Alaska Air Group, whose investment was previously announced.
In total, ZeroAvia says it has attracted $115 million of investment from a range of stakeholders including Shell Ventures, Amazon’s Climate Pledge Fund and Breakthrough Energy Ventures.
