US-German workshop series on artificial photosynthesis

Next Session: 07. December 2021, 17:00-19:00 CET | 8-10 a.m. PST | 11 a.m.-1 p.m. EST


Artificial Photosynthesis (AP) to generate useful chemicals and materials using only components of air and sunlight as inputs is a dream of visionaries and an active area of research. The AP research communities in Germany and the United States have many overlapping and complementary interests, and fruitful collaborations between them will help accelerate progress in the field. In the summer of 2020, a workshop sponsored by the BMBF in Germany and the DOE in the United States examined areas of opportunity for joint work, and recommended that an ongoing meeting series be launched to promote new connections between the scientific and engineering communities in the two countries.

This meeting series is now launched, organized by the German CO2-WIN consortium and a US-German steering committee. The kick-off workshop took place on 25 May 2021.

Below you will find the agenda of previous and upcoming workshops as well as a link to register for the free event series. Registration will enable you to receive notices for future events. Hence, you will not need to register for every session in part.
