Sorted by most advanced (stage, then maturity, then size; paused projects last). Online: actual or target commercial operation; ~ marks an approximate or target date. Maturity is where the technology itself is, from research machine to repeat builds. Capital: closed, awarded or conditional money specific to the project; company-level raises are on the Capital page. A ? marks a project with details still being verified.
