decarbonization

Vaclav Smil's talk on historic energy transitions and what they imply for climate investment. He argues that transitions are slow, technology improves gradually, and only absolute cuts in energy use would truly work.

Sabine Hossenfelder explains why hydrogen is a poor answer for decarbonization, covering how most hydrogen comes from fossil fuels, the efficiency losses of green hydrogen and reliance on rare metals in fuel cells.

Professor Ruzic explains modular micro-reactors: self-contained nuclear units with passive safety whose fuel lasts about 20 years. He covers their use for process and district heat and where they can compete with diesel generation.
