Simulation of an Ammonia Plant Integrated with the Allam Cycle for Commercial Production of Ammonia and Power

The continuous global economic and population growth results in a fast-paced energy demand and problematic emission green house gases such as CO2. To cost-effectively reduce CO2 emissions with the current main energy source of fossil fuels, novel carbon capture and utilization technologies have to be developed. One of such promising technologies is the Allam cycle power plant developed by a consortium led by Net Power LLC. Even though the human population is expected to reach about 9.2 billion by 2050,, the land availability for farming at that time could only keep the current level or even decrease. Thus, the demand…


Technology Advances for Blue Hydrogen and Blue Ammonia

ANNUAL REVIEW 2019: Blue hydrogen – defined as the version of the element whose production involves carbon capture and sequestration (CCS) – represents an alluring prospect for the energy transition.  The primary “blue” feedstocks, natural gas and coal, currently set the low-cost benchmarks for storable energy commodities.  With the addition of CCS, they are expected to set the low-cost benchmarks for low-carbon storable energy commodities.  Blue ammonia is very much included in this frame of reference since CCS could be applied to the CO2 waste stream from the Haber-Bosch process.  But neither blue hydrogen nor blue ammonia are sure things; a variety of technical, financial, regulatory, and social issues could stand in the way of their widespread adoption. But work on new technologies that have the potential to ease the way for blue products has come increasingly into view over the last twelve months.


The Allam Cycle’s Nexus with Ammonia

8 Rivers Capital, the developer of “the Allam Cycle, the only technology that will enable the world to meet all of its climate targets without having to pay more for electricity,” unveiled plans in November 2018 for a “billion-dollar clean energy production site” in New Zealand whose outputs are slated to include low-carbon ammonia. That is a sentence with a lot of angles, and unpacking it will take some effort. So let’s start right in with the Allam Cycle.
