It was super-fun to work with Alissa Ganter on this paper.
Substantial amounts of potential wind and solar generation is being curtailed in Europe.
This generation capacity could potentially be used to make hydrogen, substituting for hydrogen now made with fossil gas.

We are organizing a meeting where a small group will discuss contrasting viewpoints, identify reasons for disagreement, and explore how much of that disagreement is due to differences in empirical beliefs, decision-making frameworks, or values.

Serving as Editor-in-Chief at Science was fascinating. I greatly enjoyed working with talented and committed editorial, news, graphics, and production staff. But the inside look into scientific publishing and AAAS was also deeply disillusioning.

"We need to do hard work to bring the climate impact of our modern economy down to zero. But while we are trying to do the hard stuff, we can also grab some low-hanging fruit — no matter how high in the sky it may be."
Not sure I would go so far as to call contrail avoidance a "solution", but contrail avoidance is something we could do at very low cost that would be a small yet substantial contribution to climate risk reduction.

- Curtailed power may provide opportunities for low-efficiency H2 storage systems
- Underground H2 storage may provide value in deeply decarbonized systems
- Existing underground gas storage facilities may provide ample H2 energy storage at a national scale
- Curtailed power may provide opportunities for low-efficiency H2 storage systems
- Underground H2 storage may provide value in deeply decarbonized systems
- Existing underground gas storage facilities may provide ample H2 energy storage at a national scale
Low-cost H2 storage, and low-cost and efficient H2-to-electricity conversion, may be key to cost reduction in reliable wind-and-solar-reliant electricity systems.
