Grids need software to absorb renewables
Solar, wind, batteries and electric vehicles make the grid two-way and weather-dependent. Coordinating millions of small assets is a software problem: virtual power plants pool them, and grid intelligence platforms forecast and balance flows. Those markets grow faster than the grid hardware they manage.
Hydrogen depends on optimisation
Green hydrogen is expensive mainly because of electricity. AI that runs electrolysers when power is cheap and keeps plants healthy improves the economics directly - which is why AI for hydrogen production tops the growth table, from a small base.
Carbon gets counted
Disclosure rules and supply-chain pressure turn emissions into data that must be reported and audited. Carbon accounting software, and AI that automates it, grows as reporting obligations reach more companies.
About the data
All figures are Market-Reports.com estimates of global market revenue in US dollars, with 2025 as the base year and forecasts to 2035; growth rates are compound annual growth rates (CAGR) for 2025-2035. They come from our catalogue of more than 4,600 market reports across 19 industries, in which every market is sized on its own definition. Markets overlap - an AI server is also part of AI infrastructure - so the figures in this study must not be added together. Medians are calculated across all reports whose market name matches the theme, as published in October 2026.
