Towards a carbon-free energy system: Expectations from R&D in renewable energy technologies — •Bernd Rech1,2 and Rutger Schlatmann3,41Helmholtz-Zentrum Berlin für Materialien und Energie GmbH, Albert-Einstein-Str. 15, 12489 Berlin, Germany — 2Technische Universität Berlin, Marchstr. 23, 10587 Berlin, Germany — 3Helmholtz-Zentrum Berlin für Materialien und Energie GmbH, PVcomB Schwarzschildstraße 3 12489 Berlin, Germany — 4HTW - Hochschule für Technik und Wirtschaft Berlin, Renewable Energies, Wilhelminenhofstraße 75A, 12459 Berlin, Germany

The future global society needs a sustainable, climate-friendly energy supply largely based on a massive expansion of renewable energy sources. Photovoltaics (PV) and wind energy will become key technological pillars according to most scenarios and already today provide very low levelized cost of electricity (LCOE) in many regions and for several applications. It is important to note that for the long term the development of a system capable of trading, distributing and storing renewable energy will become necessary. This needs to be facilitated by the conversion of primary renewable energy into transportable and storable energy carriers.

Recent progress, opportunities and challenges in R&D will be highlighted for wind energy, solar thermal power plants and artificial photosynthesis on different technology readiness levels. In more detail we will discuss the development of new PV devices surpassing today*s efficiency limits as a case study how new renewable energy technologies may speed up the transition towards a sustainable energy system.
