Grannus awards EPC contract

Grannus awarded two contracts for design and technology licensing in November, and it has started December with a third announcement, naming its new EPC partner.

Yesterday's announcement, which sees the previous engineering partner entirely replaced, focuses on the company's business model, which is not to be an ammonia producer, but to be a global licensor of regional-scale ammonia plant technology.

Grannus awards engineering and licensing contracts (again)

In the last two weeks, Grannus LLC has awarded two contracts for process design and technology licensing: the first for hydrogen production, and the second for the ammonia loop.

These replace the engineering contract announced earlier this year, and bring the "zero-emission" ammonia plant closer to reality - albeit with a revised start-up schedule.

Urea production is not carbon sequestration

To make urea, fertilizer producers combine ammonia with carbon dioxide (CO2), but when farmers apply that urea to the soil, an equal amount of CO2 is emitted to the atmosphere. No CO2 is permanently stored or sequestered through the production of urea.

This is a statement of the obvious, I'm told, but it's worth stating for three reasons. First, not everyone knows it. Second, there was zero data in the academic literature supporting the fact, until now (see below). And third, next generation ammonia-urea plants with "zero-emissions" are becoming a reality, despite some of these new technologies relying on fossil fuel feedstocks.

Kern County, CA – Grannus

UPDATED: 03/01/2017 — see Change Log

OWNER: Grannus LLC
PROJECT: Greenfield polygeneration plant

SUMMARY STATUS: Planning phase
Grannus has been working to commercialize its polygeneration "Eureaka Process" since 2013, when it was a runner-up for Sustainability at the Cleantech Open. In 2015, the company closed its Series A financing, to fund engineering and feasibility work on its commercial-scale demonstration plant in California. In early 2016, Grannus awarded the engineering design contract but, in late 2016, gave the contracts to other companies, and now appears to be moving quickly to commercialize its modular, regional-scale ammonia plant design.
