Green Ammonia at Oil and Gas Scale

Alex Tancock November 16, 2020

Green Ammonia demand will grow massively over the coming years as it takes a central role in decarbonization, particularly in hard to abate sectors. In order to meet this demand, the industry must respond with projects at oil and gas scale.  This is the only way to deliver the volumes required to decarbonize and to do it at the prices needed to accelerate the energy transition.  The project concept pioneered by Intercontinental Energy offers a way forward. This presentation will outline Intercontinental Energy’s view of the green ammonia market and summarize the project template used throughout the global portfolio, followed by an…

Our Improved Farm Tractor Ammonia and Hydrogen Fueling System

David Toyne November 13, 2019

We have a large farm tractor that is fueled by a mixture of ammonia and hydrogen, or hydrogen alone. We will briefly describe the fueling and ignition improvements that have been made to the engine, and quantify the performance increases. These improvements can be applied to other internal combustion engine applications. This tractor runs only on renewable and CO2 free fuels.

Creating a Redox Materials Database for Solar-Thermochemical Air Separation and Fuels Production

Converting heat from renewable sources into other forms of energy is considered an essential factor in the reduction of greenhouse gas emissions. For instance, high temperatures can be reached using concentrated solar power (CSP), and the thus-captured energy can be converted into so-called solar fuels via thermochemical processes. These consist of the partial reduction of a redox material, usually a metal oxide, at high temperatures following the exothermic re-oxidation of this material at a lower temperature level using steam or CO2, which are thus converted into hydrogen or carbon monoxide, respectively. These two gases can be combined to generate syngas…

Screening Binary Redox Pairs for Solar Thermochemical Ammonia Synthesis Using Machine Learned Predictions of Gibbs Formation Energies at Finite Temperatures

Christopher BartelJohn RumptzAaron HolderAlan WeimerCharles Musgrave November 2, 2017

Solar thermochemical ammonia synthesis (STAS) is a reduction/oxidation (redox) cycle which enables the production of ammonia (NH3) from air, water, and concentrated sunlight. In this process, a metal nitride (MN) is oxidized by steam to produce a metal oxide (MO) and NH3; the resulting MO is reduced at high temperature (driven by concentrated solar radiation) and subsequently used to reduce atmospheric nitrogen (N2) and reform the MN and restart the NH3 synthesis cycle. The identification of optimal redox pairs (MO/MN) for this process has been historically limited by the lack of thermochemical data (i.e., Gibbs formation energies at finite temperatures)…
