Gigaton raises $26 million Series A for AI that cuts industrial emissions and costs | carboncredit.io

Gigaton, a London-based AI company formerly known as Carbon Re, has raised $26 million in Series A funding led by Plural. The company makes control software for energy-intensive industrial plants, starting with cement. Its system replaces older plant controls and makes real-time adjustments to fuel mix, kiln speed, and oxygen levels to cut both costs and carbon emissions. Current deployments with Mannok Holdings, Adani Cement, Heidelberg Materials, and Holcim are saving $1 million to $3 million per plant each year and cutting about 30,000 tonnes of CO2 per site. Gigaton plans to expand into steel, glass, and chemicals, and will use the funding to grow its headcount fivefold. The round also included 2150, Semapa Next, and existing investors. Heavy industry faces rising energy costs and pressure to decarbonize, but many plants run on decades-old control systems. Gigaton's pitch is that its AI can handle the complexity of alternative fuels and variable inputs better than manual operators. The company spent five years studying plant control rooms before deploying its system in live settings.
