Infrastructure is where clean technology stops being a forecast and starts meeting land, grid capacity, planning, utilisation, finance and operational reality.
This page covers
grid constraints, wind curtailment, depot infrastructure, hydrogen refuelling, industrial energy demand, flexibility, storage, data centre power demand, planning constraints and infrastructure financeability.
Last updated: May 2026
Overview
This page brings together analysis and tools on hydrogen refuelling, grid constraints, wind curtailment, depot charging, fleet infrastructure and the commercial realities that decide whether a deployment plan survives contact with the ground.
Core Themes
- hydrogen refuelling economics, station utilisation and corridor deployment
- grid connection delays, power availability and site constraints
- fleet depot charging, public charging downtime and operational fit
- wind curtailment, flexibility, storage and local demand creation
- infrastructure sequencing, anchor customers and financeability
Featured Articles & Field Notes
These articles and field notes examine where infrastructure determines whether technology can actually deploy: grid capacity, curtailment, site power, refuelling networks, industrial demand, planning and flexibility.
Core argument: Infrastructure is where technology claims meet deployment reality.

FAQ
Why do grid constraints matter for fleet decarbonisation?
Grid constraints can turn fleet electrification from a vehicle decision into a site and infrastructure problem.
Why does wind curtailment matter commercially?
Curtailment matters because it can increase system costs, reduce generator output, affect consumer bills and change the investment case for storage, flexibility, hydrogen production and grid reinforcement.
