Cement’s Future Is Less Portland, Not One Magic Cement

6 min read

Cement decarbonization attracts miracle stories. One company has a new binder. Another has a carbon-negative aggregate. Someone else has an electrochemical process, a hydrogen kiln, a low-carbon limestone route, a supplementary cementitious material, a recycled cement process or a carbon-capture retrofit. Some of these ideas are useful. Some will become … [continued]

Steel keeps getting framed as a hydrogen problem because hydrogen gives the sector a single shiny lever. Replace coal with hydrogen, keep making new iron, plug it into an electric arc furnace, and declare victory somewhere around the ribbon-cutting ceremony. It is an attractive story for governments, incumbent producers, electrolyzer … [continued]
