Low Carbon Ammonia via Methane Pyrolysis

Rob Hanson

Splitting methane into hydrogen and carbon (methane pyrolysis) allows for the utilization of one of the largest energy reserves on our planet (natural gas) without emitting carbon dioxide, since only the hydrogen is oxidized to release energy, while the carbon is permanently sequesters as a solid product often replacing products that have their own GHG emissions. If you split biogenic methane (that produced from the anaerobic digestion of biomass), carbon dioxide is pulled out of the atmosphere resulting in a carbon negative process for making hydrogen (and in turn ammonia), and presenting a long term opportunity to begin drawing CO2…

Low-carbon ammonia in Nebraska and the Netherlands

Trevor Brown October 15, 2020

Last week, two new low-carbon ammonia production projects were announced, both of them large-scale and largely CO2-free. Monolith Materials announced a 275,000 ton per year “clean ammonia” plant in Nebraska, in the heart of the US cornbelt. The plant will begin construction in 2021, expanding the existing demonstration plant, using Monolith’s methane pyrolysis process powered by 100% renewable electricity. Ørsted and Yara announced their plan to produce 75,000 tons per year of “green ammonia” at Yara’s existing Sluiskil plant in the Netherlands. They intend to install a 100 MW electrolyzer, using Ørsted’s offshore wind energy, with a final investment decision expected in 2021-2022, and production beginning in 2024-2025.

Methane splitting and turquoise ammonia

Cedric Philibert May 14, 2020

Most hydrogen today is produced from fossil fuels – steam methane reforming of natural gas, partial oxidation of coal or oil residues – and entails large CO2 emissions. This fossil hydrogen can be called “grey hydrogen”. Or sometimes, brown. The same color scheme applies to the ammonia produced from it, so we have “grey ammonia.” Or brown ammonia, your call. The exact carbon footprint depends on the fuel used and the efficiency of the facility, so you could easily identify many shades of grey. There is, however, another option to deliver clean hydrogen – and now another colour: turquoise, or green-blue (or blue-green). This is the colour of hydrogen from methane pyrolysis, a process that directly splits methane into hydrogen and solid carbon. Instead of being a waste, like CO2, that must be disposed of safely, solid carbon is potentially a resource.

Australian Company Advances Low-Carbon Hydrogen from Methane

Stephen H. Crolius January 16, 2020

Hazer Group, an Australian company with technology in development for the production of low-carbon hydrogen, had a busy 2019. In April the company announced that it had received its first Australian patent. In September, the Australian Renewable Energy Agency (ARENA) announced the approval of “up to [AUD]$9.41 million in funding to Hazer … for the construction and operation of a groundbreaking hydrogen production facility in Munster, Western Australia.” In December Hazer announced that it was negotiating an agreement with industrial gas distributor BOC related to its Munster project. Last week the company announced that it had secured up to AUD$250,000 in grant funding from the Government of Western Australia for “a feasibility study on the creation of a renewable hydrogen transport hub." in the City of Mandurah.

Monolith Materials: Ammonia Production from Natural Gas Using Pyrolysis

Tim Rens Rob Hanson

Monolith Materials was founded in 2013 with the vision of converting abundant natural gas resources into valuable products for customers around the world. We have developed a novel electric process for converting natural gas into carbon, in the form of carbon black, and hydrogen, at high yield. Our first commercial unit (15,000 T/y of carbon and 5,000 T/y of hydrogen) is fully financed and under construction. It will come online in 2019. We plan on expanding this facility by adding as many as 30 additional units over the coming years. We are actively pursuing opportunities to increase the value of…

Methane to Ammonia via Pyrolysis

Stephen H. Crolius January 27, 2017

Eric McFarland, Professor of Chemical Engineering at the University of California Santa Barbara, likes fossil fuels and nuclear energy and is unimpressed by the menu of renewable energy technologies. But he is worried about climate change and he has an original view on how to modify our current energy system so that we don’t overload the atmosphere with CO2. He believes the key will be to separate fossil hydrocarbons into gaseous hydrogen and solid carbon. The chemistry he is developing in this area involves transferring “electrochemical potential” from hydrocarbons to alternative energy carriers. Ammonia is an energy carrier that McFarland believes is especially promising.
