Solar power to reach 25 pct electricity production by 2050




Photovoltaic and Concentrating Solar Power are seen as the key solar technologies to increase adoption over the long term.  …

…   “The combination of solar photovoltaics and concentrating solar power offers considerable prospects for enhancing energy security while reducing energy-related CO2 emissions by almost six billion tonnes per year by 2050. The roadmaps detail the technology milestones that would make this possible …”   …

Via IEA: Technology Roadmap.

Concentrated solar will require infrastructure investments to transport the electricity generated in remote, sunny regions.  …

…   “IEA expects CSP to become competitive for peak and mid-peak loads by 2020 in the sunniest places if appropriate policies are adopted. Its further expansion will depend on the development of dedicated transport lines that will bring CSP electricity to a greater number of large consumption centres. Some of them will have to be developed within large countries such as China, India and the USA. Others will cross border, and many will be needed to link the southern and northern shores of the Mediterranean Sea. ”   …

IEA sees solar at quarter of world electricity by 2050.

Solar photovoltaic technology roadmap (PDF).  New technology is needed to support grid integration.  …

…   “The PV industry, grid operators and utilities will need to develop new technologies and strategies to integrate large amounts of PV into flexible, efficient and smart grids.”   …

Concentrating solar power technology roadmap (PDF).  CSP will require energy storage to meet 24 hour coverage of power needs.  …

…   “integrated thermal storage is an important feature of CSP plants, and virtually all of them have fuel-power backup capacity. Thus, CSP offers firm, flexible electrical production capacity to utilities and grid operators while also enabling effective management of a greater share of variable energy from other renewable sources … ”   …
