Research & Development

This is where American Katerra documents the work that comes before a product: the names, the measurement procedure, and the supply chain that lower-carbon steel needs before it reaches a U.S. jobsite. Each program is described as it stands today, and each part of it moves to Products when it can be supplied.

Hydrogen Steel is the research and development program of American Katerra and Yamaguchi Heavy Industries Ltd. for steel made from iron reduced with hydrogen in place of coke. It is defined under five names, Green, Blue, Pink, Turquoise, and White Hydrogen Steel™, each telling you where the hydrogen came from, with the carbon of every tier measured and disclosed under our Blue Carbon Steel™ procedure. No tier can be ordered for a U.S. project yet, and the page states where each one stands today.
