Auke had a great thread and presentation on why electric trucking looks extremely promising. IMHO the biggest issue there now is grid support for fast highway charging for trucks. Peak loads are in the MWs per truck stop.

Morning team call had two questions - which made me pull together some loose thoughts on Climate Tech VC. 🧵

1) Has the growth/presence of VC impacted your sector over the last 3-5 years?
2) If so, what are the implications of a severe slowdown/reduction in funding from VC?

Good thread on current trends in climate VC and public markets, and what it might mean for fundraising and exits.

The Electric Grid is THE Bottleneck to Decarbonizing Energy by 2050

by

Liza B Reed

Ensuring a clean energy future for the United States requires a stronger electricity grid — one that can move more power over longer distances while also supporting new loads like electric vehicle charging and energy-intensive industrial processes, and providing reliable service through more extreme

The electric grid, and specifically long-distance power transmission, is now the number one bottleneck to decarbonizing electricity. Great piece by @LizaBReed

Probabilistic feasibility space of scaling up green hydrogen supply

by

Adrian Odenweller

Green hydrogen and derived electrofuels are attractive replacements for fossil fuels in applications where direct electrification is infeasible. While this makes them crucial for climate neutrality, rapidly scaling up supply is critical and challenging. Here we show that even if electrolysis capacit

Great paper! I think your conclusions out to 2030 are very reasonable. I do think the bottleneck is much more likely to be demand and firm offtake contracts (along with permitting for all the renewables / transmission needed) rather than supply of electrolyzers per se.
