Includes back-of-envelope calculations on capture costs that are valuable for engineers entering the space.

Today’s Synthesis

The throughline across today’s items is that electrification is outpacing grid planning — and that’s where engineers are urgently needed. US Steel’s $2B DRI plant and Massachusetts’ heat-pump winter rates both show that industrial and residential electrification are moving faster than grid infrastructure can adapt. Steel plants and millions of heat pumps are coming online, but the distribution grid wasn’t designed for this load profile. That’s where RMI’s Reliability Dashboard becomes critical — it gives planners a decade of outage data to target upgrades precisely. If you’re a software or ML engineer considering a climate pivot, grid reliability tooling is a high-leverage entry point: the data infrastructure is immature, the optimization problems are hard, and the demand signal is unambiguous. Start by exploring open grid datasets (e.g., DOE’s grid resilience tools) and ask: where is the forecasting or topology optimization layer missing?
