In the last 12 months ... IHI Corporation tested its 1 kW ammonia-fueled solid oxide fuel cell (SOFC) in Japan; Project Alkammonia concluded its work on cracked-ammonia-fed alkaline fuel cells (AFC) in the EU; the University of Delaware's project for low-temperature direct ammonia fuel cells (DAFC) continues with funding from the US Department of Energy's ARPA-E; and, in Israel, GenCell launched its commercial 4 kW ammonia-fed AFC with field demonstrations at up to 800 locations across Kenya.
Last week, OCP Group announced plans to develop green hydrogen and green ammonia as sustainable raw materials for use in fertilizer production. This includes building pilot plants in both Germany, already under construction, and Morocco, yet to begin construction, as well as "the possible establishment of an African Institute for Solar Ammonia."
In June, ThyssenKrupp announced the launch of its technology for "advanced water electrolysis," which produces carbon-free hydrogen from renewable electricity and water. This "technology enables economical industrial-scale hydrogen plants for energy storage and the production of green chemicals."
Two weeks later, in early July, ThyssenKrupp announced that it was moving forward with a demonstration plant in Port Lincoln, South Australia, which had been proposed earlier this year. This will be "one of the first ever commercial plants to produce CO2-free 'green' ammonia from intermittent renewable resources."
The German conglomerate is one of the four major ammonia technology licensors, so its actions in the sustainable ammonia space are globally significant.
GenCell Energy, the Israeli fuel cell manufacturer, has made two major announcements in the last month. In June, it unveiled its ammonia-fueled alkaline fuel cell system. In July, it announced its first commercial customer.
Its A5 Off-Grid Power Solution is a "nano power plant that operates fully independent of the grid." The first phase of product trials, using ammonia as a fuel to provide uninterruptible power to cell phone masts, will begin in Kenya by the end of this year, and "product roll-out" is expected in the second half of 2019.
New ammonia production capacity is being built in southern Africa. The outputs will support agricultural development in the region – but could also support development of ammonia as a universal energy commodity. A British start-up company is currently at work to develop a beachhead use case for ammonia energy.
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.
This week, an important new voice joined the chorus of support for renewable ammonia and its potential use as an energy vector - the International Energy Agency (IEA).
In his article, Producing industrial hydrogen from renewable energy, Cédric Philibert, Senior Energy Analyst at the IEA, identifies a major problem with the hydrogen economy: hydrogen is currently made from fossil fuels. But his argument for producing hydrogen from renewable energy leads almost inevitably to ammonia: "In some not-too-distant future, ammonia could be used on its own as a carbon-free fuel or as an energy carrier to store and transport energy conveniently."
This week, at the World Economic Forum in Davos, the leaders of 13 global companies, representing more than EUR 1 trillion in annual revenues, announced the launch of the Hydrogen Council.
This new global initiative is important for obvious reasons: it presents a compelling "united vision and long-term ambition" for hydrogen, it promises global engagement with "key stakeholders such as policy makers, business and hydrogen players, international agencies and civil society," and it pledges financial commitments to RD&D totaling EUR 10 billion over the next five years.
It is important for a subtler reason too: it is the first hydrogen industry promotion I've seen that includes ammonia. It includes ammonia both implicitly, encompassing "hydrogen and its compounds," and explicitly, listing ammonia as a "renewable fuel" in its own right.
