在欧盟的FP7-Solugas项目中，论证了带有增压空气接收器和燃气轮机的太阳能混合动力技术的可行性。在过去的几年里，太阳能热与空气-布雷顿循环的耦合被认为是加速CSP市场渗透的一种方式，直接与传统的联合循环电厂竞争。这种混合CSP产品的商业化之路是通过扩展太阳能燃气轮机的容量和提高接收器出口温度。Soltrec项目专注于容积式接收器的开发、制造和测试，该容积式接收器能够将压缩空气的最高温度提高到1000℃。容积式空气接收器的概念是在这些温度水平下获得高效率的最有前途的选择，在设计点运行时太阳能份额高达80%。在这种温度水平下，将太阳辐射转化为热压空气会产生热应力和机械应力，这需要创新的接收器设计和新的耐热材料的应用。为了显著增加太阳能份额并降低混合发电厂的成本和环境影响，Soltrec空气接收器已在位于西班牙塞维利亚的Sanlúcar la Mayor的Abengoa太阳能研发设施中试运行。
During the EU FP7-Solugas project the feasibility of the solar hybrid technology with a pressurized air receiver and a gas turbine was demonstrated. Over the last years the coupling of solar heat to air-Brayton cycles has been identified as a way to accelerate the CSP market penetration competing directly with conventional combined cycle plants. The path to the commercialization of this hybrid CSP product goes through the scaling of the solarized gas turbine capacity and the increase of the receiver outlet temperature.The Soltrec project focuses on the development, manufacturing and testing of a volumetric receiver, capable to raise the maximum temperature of the compressed air up to 1000 °C. The concept of volumetric air receivers is the most promising option for getting high efficiencies at these temperature levels, with solar shares of up to 80% at design point operation. Transforming solar radiation into hot pressurized air at these temperatures levels leads to thermal and mechanical stresses that requires an innovate receiver design and the application of new heat resistant materials.With the objective of significantly increasing the solar share and lower the costs and environmental impact of the hybrid plants the pilot Soltrec air receiver has been commissioned at the Abengoa Solar R&D facilities at Sanlúcar la Mayor (Seville, Spain).
