Low-carbon ammonia in Nebraska and the Netherlands
Article

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.

US Senators Show Strong Interest in Ammonia-Fueled Shipping
Article

The Senate Energy and Natural Resources Committee, led by Chairman Lisa Murkowski (R-Alaska) and Ranking Member Joe Manchin (D-West Virginia), recently hosted a hearing on offshore energy technologies. I was invited to testify on technology and policy options for eliminating greenhouse gas emissions from the marine shipping sector, and I used the opportunity to spotlight ammonia's central role in that effort.

EPRI, GTI Launch Low-Carbon Initiative
Article

Last month the Electric Power Research Institute (EPRI) and the Gas Technology Institute (GTI) announced a new undertaking: the Low-Carbon Resources Initiative (LCRI). According to the organizations’ press release, over the next five years they will work together and with collaborating companies to “accelerate the development and demonstration of low-carbon energy technologies.”

Zero emission aircraft: ammonia for aviation
Article

This week, Reaction Engines announced a “ground-breaking study” on ammonia as a fuel for zero-emission aircraft. This will soon be followed by a demonstration project, “integrating the technology into a ground-based test engine.” The study combines Reaction Engines’ heat exchanger technology with the ammonia cracking technology being developed by the UK’s Science and Technology Facilities Council (STFC). By partially cracking green ammonia to hydrogen, the resulting ammonia fuel mix “mimics jet fuel,” making it possible to adapt existing engines and aircraft to use zero-emission fuels. “This means a fast transition to a sustainable aviation future is possible at low cost.”

Methane splitting and turquoise ammonia
Article

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.

A 100% Solution to Climate Change: Why is Ammonia Necessary?
Article

It’s easy for people working on a particular technology or product to get overly focused on its wonderful promise. Sometimes we forget to consider whether or how our favorite idea fits into the larger issue. Of course, nearly everyone reading this piece in Ammonia Energy will be heartily into the idea of green ammonia as an energy carrier in a zero-emissions world. But let’s keep things in context – is green ammonia one good idea, one possibility, or is it an absolute requirement of a full solution to climate change? I looked at this question, not only for ammonia but for every category of technology, in the research and analysis project that became The 100% Solution, a recently-published book. It lays out five “pillars” that constitute the physical minimum steps needed to solve climate change.
