Zero emission aircraft: ammonia for aviation

Trevor Brown August 20, 2020

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.”

Hydrogen Stands Out in BP's New Strategy

Stephen H. Crolius August 13, 2020

Last week oil major BP released its second quarter financial results – and used the occasion to share the company’s new strategy. “We aim to be a very different kind of energy company by 2030,” the company said, “as we scale up investment in low-carbon, focus our oil and gas production and make headway on reducing emissions.” “Investment in low-carbon” turns out to involve full embrace of the hydrogen paradigm circa 2020: power-to-gas; carbon capture, utilization, and storage; and the possibility of a “hydrogen export” business based on ammonia.

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.

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

Solomon Goldstein-Rose April 29, 2020

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.

ARPA-E Issues RFI for Next-Gen Ammonia System Integration

Stephen H. Crolius February 27, 2020

This week the United States Department of Energy’s Advanced Research Projects Agency – Energy (ARPA-E) issued a Request for Information under the title “Next Generation Ammonia System Integration Project.” This is a strong signal that ARPA-E intends to see the ammonia energy technologies in its portfolio through to commercial fruition.
