To rapidly reduce CO2 emissions and make our energy mix greener, we need more than sustainable technologies alone. A sustainable business model is equally important. After all, a successful business model for sustainable technology is worth its weight in gold. In this series we discuss promising techniques and dive deeper into the revenue model behind the technology. Where lie the opportunities? Which obstacles still need to be overcome?

They explain how the technology works, touch upon the legal framework and explore how financing can contribute to accelerating the technology. Last Thursday we discussed Carbon Capture and Storage, CCS in short.
