Australian solar-ammonia exports to Germany

I recently wrote about a vast future market for merchant ammonia: transporting carbon-free energy from Australia's deserts to Japan's electricity grid.

Now, however, it is clear that Japan could face international competition for Australia's solar-ammonia resources. Jeff Connolly, CEO of Siemens Pacific, wrote last month about his ambitions for ammonia as an energy export commodity.

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.

Penwell, TX — TCEP

UPDATED: 10/03/2017 — see Change Log

OWNER: Texas Clean Energy Project (Summit Power Group LLC)
PROJECT: Greenfield plant, urea

SUMMARY STATUS: Financing phase
This was going to be a major "clean coal" power plant with significant urea byproduct but DOE effectively killed the project when it suspended funding in mid-2016. Originally scheduled to be completed by 2014, the project was already severely delayed. After the DOE withdrew funding, the developers were trying one last idea: ditching power generation altogether and focusing on urea production.
