欧洲联盟尚未确定如何确切地达到其未来的温室气体排放目标。一个潜在的解决方案是在北非地区大规模开发聚光太阳能发电（CSP），将电力输送到欧洲。CSP是一种相对年轻且很少使用的技术，与其他发电方法相比价格昂贵。可行性研究表明，非洲的CSP工厂可以产生足够的电力，以推动欧盟的气候目标。然而，这样一个项目的成本却鲜为人知。目前，CSP必须与低成本的燃煤电厂竞争，严重阻碍了发展。我们研究了北非CSP平准化电力成本所需的可能投资成本，以等同于燃煤电厂的成本，以及在技术达到价格平价之前鼓励增长所需的潜在补贴成本。我们还研究了投资和补贴对关键因素变化的敏感性。我们发现，补贴金额的估计是合理的欧盟和感知风险和学习率等因素的敏感性，使政策制定者能够积极影响的补贴成本和所需的时间CSP与煤炭竞争。
The European Union has yet to determine how exactly to reach its greenhouse gas emissions targets for the future. One potential answer involves large-scale development of concentrated solar power (CSP) in the North African region, transmitting the power to Europe. CSP is a relatively young and little utilized technology and is expensive when compared to other methods of generation. Feasibility studies have shown it is possible to generate enough power from CSP plants in Africa to spearhead the EUs climate goals. However, the costs of such a project are less well known. Currently, CSP must compete with low cost coal-fired electricity plants, severely hindering development. We examine the possible investment costs required for North African CSP levelized electricity cost to equal those of coal-fired plants and the potential subsidy costs needed to encourage growth until the technologies reach price parity. We also examine the sensitivity of investment and subsidies to changes in key factors. We find that estimates of subsidy amounts are reasonable for the EU and that sensitivity to such factors as perceived risk and learning rates would enable policy-makers to positively influence the cost of subsidies and time required for CSP to be competitive with coal.
