SustainX已经获得来自GE能源金融服务公司和其他投资者共1440万美元投资，以继续发展压缩空气储能技术。
SustainX之前总共获得了540万美元的早期投资，分别来自美国国家科学基金会的小企业创新研究计划，以及美国能源部储能项目。
AES储能公司正与SustainX公司一道建一个全尺寸系统示范项目，该项目储存的能量够1000户美国家庭的用量。
这项投资部分是基于GE全球研发中心的SustainX的技术评价。
SustainX的技术使空气保持在一个接近恒定的温度下压缩和膨胀。这大大提高了效率，并使压缩空气储能成本低于了那些在地面上的储能技术成本。
SustainX has secured $14.4m funding from GE Energy Financial Services and other investors to continue developing its technology for energy storage using compressed air.
GE Energy Financial Services joins Cadent Energy Partners and prior investors Polaris Ventures and Rockport Capital, for the new round of financing, under the GE Ecomagination Challenge's Powering the Grid program, in which SustainX is a partner.
SustainX has received a total of $5.4m earlier financing from the Small Business Innovation Research program of the National Science Foundation and from the Energy Storage Program of the US Department of Energy.
AES Energy Storage is working with SustainX to demonstrate a full-size system in the field, capable of storing enough energy to power 1,000 typical US homes.
The investment is based partly on GE Global Research's eva luation of SustainX's technology.
To store energy, SustainX compresses air by using electricity to drive pistons inside cylinders and the resulting high-pressure air is stored in above-ground vessels.
To release energy later, the system uses stored air to drive the same pistons, which in turn drive an electric generator.
SustainX technology keeps air at a nearly constant temperature during compression and expansion, this significantly improves efficiency and reduces the cost of compressed-air energy storage below that of other above-ground energy-storage options.
