Green Hydrogen, Spaceship Earth, and a Circular Economy
December 2020Based on a review of the literature, researchers synthesize some aspects which represent in their understanding the essence of the circular economy concept. While in no way intended to be absolute, definitive and final, these aspects represent a level of understanding of the concept at this specific moment.
Societal Consequences to the Transition to Green Hydrogen
The need for green hydrogen is likely to require massive expansion of renewable energy plants. Researchers have identified a gap between political action, technological developments, and expertise from the social sciences and humanities as the world transitions from fossil fuels to green hydrogen. They argue that the respective funding and … Continue reading
