H2Prism updates

A chronological index of H2Prism calculator, dataset, and product updates.

This is the change index for H2Prism—not the product overview. It records updates that affect how practitioners discover, interpret, or use the calculators and structured data.

Latest site update

Search and discovery: H2Prism routes now provide static, route-specific summaries for calculators and data collections, so the core purpose and limitations remain available without JavaScript.

Data maintenance

Policy, offtake, reports, equipment specifications, installed-cost references, and project evidence are maintained as separate datasets. Use the links on each data page to review the record scope and original sources.
