据油气新闻网6月7日报道，沙特阿美石油公司和意大利埃尼集团日前表示，两家的合资企业已携手全球最大客运航空公司美国联合航空公司投资英国初创企业OXCCU，以降低低碳航空燃料的过高成本。
航空业产生的温室气体约占全球排放量的2%，而该行业自己的目标是到2050年排放量不超过森林等自然资源或其他技术所能吸收的排放量，这构成了一个特别艰巨的挑战。
由美国投资商Clean Energy Ventures领投2270万美元的这项投资将捐给在OXCCU的牛津大学附属科学家，OXCCU是一直在寻找飞机发动机中煤油和汽油替代品的公司之一。
OXCCU表示，其可以通过将从工业或发电厂捕获的二氧化碳与使用可再生电力生产的氢气相结合来制造燃料。它的突破在于使用铁基催化剂一步到位，取代了通常需要进行化学反应的更昂贵的两阶段工艺。
两家公司在一份声明中表示，以这种方式简化流程可以降低50%的成本，并减少副产品的产生。
美联航风险投资公司总裁Michael Leskinen表示，这一尖端解决方案可能是美联航在不依赖传统碳抵消方式的情况下，到2050年实现净零碳排放承诺的一条具有成本效益的途径。

Aramco ,ENI,United Airlines invest in a low-carbon fuel venture
The venture units of oil firms Aramco and Italy's ENI have joined the world's largest passenger carrier United Airlines to invest in British start-up OXCCU's efforts to slash the prohibitively high cost of lower-carbon aviation fuel, the companies said.
Aviation produces around 2 per cent of the world's planet-warming emissions and the sector's own targets to emit no more than can be absorbed by natural sinks like forests or other technologies by 2050 pose a particularly daunting challenge.
The $22.7 million investment, led by US-based investor Clean Energy Ventures, will go to Oxford University-affiliated scientists at OXCCU, one of several companies that have been searching for ways to replace kerosene and gasoline in plane engines.
OXCCU says it can make fuel by combining carbon dioxide captured from industry or power plants with hydrogen made using renewably sourced electricity. Its breakthrough is in using an iron-based catalyst to do this in one step, replacing the pricier two-stage process that is usually needed to bring about the chemical reaction.
Streamlining the process in this way knocks 50 per cent off the capital cost and produces fewer byproducts, the companies said in a statement.
"This cutting-edge solution could be a cost-effective pathway for United to reach our commitment of net-zero carbon emissions by 2050, without relying on traditional carbon offsets," said United Airlines Ventures President Michael Leskinen.
