Second Day Added to NH3 Energy+ Conference

Stephen H. Crolius May 11, 2017

The “NH3 Energy+: Enabling Optimized, Sustainable Energy and Agriculture” Topical Conference, originally conceived as a one-day event, has been extended to a second day, according to NH3 Fuel Association (NH3FA) President Norm Olson. “NH3 Energy+” is the 2017 edition of the NH3 Fuel Conference that has been held every year since 2004. This year it will be held under the auspices of the American Institute of Chemical Engineers’ Annual Meeting in Minneapolis in the U.S.

The Hydrogen Consensus

Stephen H. Crolius April 27, 2017

Let’s say there is such a thing as the “hydrogen consensus.” Most fundamentally, the consensus holds that hydrogen will be at the center of the sustainable energy economy of the future. By definition, hydrogen from fossil fuels will be off the table. Hydrogen from biomass will be on the table but the amount that can be derived sustainably will be limited by finite resources like land and water. This will leave a yawning gap (in the U.S., 60-70% of total energy consumption) that will be filled with the major renewables -- wind, solar, and geothermal -- and nuclear energy. This may be as far as the consensus goes today, but more detail is now emerging on the global system of production and use that could animate a hydrogen economy.

The new generation of fuel cells: fast, furious, and flexible

Trevor Brown April 12, 2017

At ARPA-E's recent Energy Innovation Summit in Washington, DC, Program Director Grigorii Soloveichik presented his vision for the future of transportation: hybrid electric vehicles that combine the advantages of both plug-in battery and fuel cell technologies. This "optimal solution" will require a new generation of fuel cell that is "fast, furious, and flexible." Fast, in terms of start-up / shut-down time. Furious, in terms of energy density. And flexible, in terms of fuel choice - specifically sustainable liquid fuels, like ammonia.

NH3 Energy+: Topical Conference at AIChE Annual Meeting

Stephen H. Crolius April 07, 2017

“Ammonia Energy Arrives on World Stage.” This could have been the headline for today's story about the 2017 NH3 Fuel Conference that will be staged in conjunction with the American Institute of Chemical Engineers (AIChE). But that would be hyperbolic and would also single out just one step of ammonia energy's rise to global prominence. Nonetheless, the full-day event, officially entitled, “NH3 Energy+: Enabling Optimized, Sustainable Energy and Agriculture,” is unquestionably a milestone on the journey.

Solar-Bio-GMO-Ammonia, powered by the 'Bionic Leaf'

Trevor Brown April 07, 2017

There will be many ways to make ammonia in the future and, regardless of breakthroughs in chemical catalysts and engineering design, genetically modified organisms will play an increasingly important role. At this week's American Chemical Society meeting, Daniel Nocera from Harvard University introduced his new ammonia synthesis technology. It builds on his "artificial leaf" that produces and stores hydrogen using power from sunlight. Nocera's latest innovation is to couple this system with a microbe that naturally contains nitrogenase, the enzyme that fixes atmospheric nitrogen into ammonia. The end result - a robust population of nitrogen fertilizer-emitting microbes - can be delivered to the soil simply by watering the plants.

ACS "Ammonia Economy" Call for Papers Deadline Extended

Stephen H. Crolius March 23, 2017

The deadline for abstracts for the Ammonia Economy session at the American Chemical Society (ACS) National Meeting in August has been extended to April 3. This was reported in an interview yesterday with Martin Owen Jones, Energy Materials Coordinator for the ISIS neutron spallation facility at the Rutherford Appleton Laboratory in the United Kingdom. Jones is the co-organizer of the session along with Michael Mock, a Catalysis Scientist at Pacific Northwest National Laboratory (PNNL) in the U.S. The session will be the most prominent treatment of ammonia energy to date at a scientific conference held by an organization of global stature.

Terrestrial Energy and the Production of Carbon-Free Ammonia

Stephen H. Crolius March 16, 2017

On January 24, the nuclear energy company Terrestrial Energy USA informed the United States Nuclear Regulatory Commission of its plans “to license a small modular, advanced nuclear reactor in the United States.” Many steps later – sometime in the 2020s – the American subsidiary of the Canadian company Terrestrial Energy, Inc., hopes to bring its IMSR technology to market. IMSR stands for integral molten salt reactor. The IMSR stands apart from conventional nuclear technology on several dimensions. On the dimension of operating temperature, the IMSR is hot enough that it can be beneficially integrated with high-temperature industrial processes. According to the company’s research, ammonia production could be a candidate for such integration.

International R&D on sustainable ammonia synthesis technologies

Trevor Brown February 03, 2017

Over the last few weeks, I've written extensively about sustainable ammonia synthesis projects funded by the US Department of Energy (DOE). While these projects are important, the US has no monopoly on technology development. Indeed, given the current uncertainty regarding energy policy under the Trump administration, the US may be at risk of stepping away from its assumed role as an industry leader in this area. This article introduces seven international projects, representing research coming out of eight countries spread across four continents. These projects span the breadth of next-generation ammonia synthesis research, from nanotechnology and electrocatalysis to plasmas and ionic liquids.

US DOE funding research into sustainable ammonia synthesis

Trevor Brown January 27, 2017

The US Department of Energy (DOE) is currently supporting six fundamental research projects that will develop "novel catalysts and mechanisms for nitrogen activation," which it hopes will lead to future sustainable ammonia synthesis technologies. These projects, announced in August 2016 and administered by the Office of Basic Energy Sciences, aim "to investigate some of the outstanding scientific questions in the synthesis of ammonia (NH₃) from nitrogen (N₂) using processes that do not generate greenhouse gases."

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.
