climate

The first act of climate tech was a price story. Solar modules, wind turbines and lithium cells fell far enough that deployment stopped needing a moral argument. The second act is a systems story, and it is harder, slower and much less photogenic.

• Industrial heat above 400°C — cement, glass, chemicals — where electrification is technically awkward and capital-intensive.
• Steel, where hydrogen-based reduction works in pilots and struggles on cost.
• Heavy transport and shipping, waiting on fuel supply chains rather than engine technology.
• Transmission and distribution, the constraint that makes everything else slower than the models assume.
