The second annual European Conference on Sustainable Ammonia Solutions has announced its full program, spread over two days, May 17 and 18, 2018, at Rotterdam Zoo in the Netherlands. The international cadre of speakers, representing a dozen countries from across Europe as well as the US, Canada, Israel, and Japan, will describe global developments in ammonia energy from the perspectives of industry, academia, and government agencies.
Last week, in Part 1 of this series on electrochemical ammonia synthesis technologies, I quoted a recent article by researchers at MIT that identified avenues for future research and development. One option was a biomimicry approach, learning from "enzymatic catalysts, such as nitrogenases," which can "either be incorporated into or provide inspiration for the design of electrocatalytic processes."
The nitrogenase enzyme, nature's ammonia synthesis technology, was developed in an iterative innovation process, otherwise known as evolution, that took hundreds of millions of years to reach this level of efficiency. According to one group of electrochemists, who presented their results at the recent NH3 Energy+ conference, nitrogenase produces ammonia in nature with an enviable 75% process efficiency - so it's no surprise that they are basing their industrial technology on it.
The NH3 Fuel Association (NH3FA) has released the names of the organization’s charter group of sponsors. The common thread that unites the six companies? A conviction that ammonia energy represents a significant opportunity for their businesses. The sponsors are Yara, Nel Hydrogen, Airgas, Haldor Topsoe, Casale, and Terrestrial Energy.
“Carbon-free ammonia needs to be a significant contributor to the [email protected] initiative.” This was one of the “key takeaways” offered by Steve Szymanski, Director of Business Development at the hydrogen generator company Proton On-Site, during his presentation at the [email protected] Workshop that was held on May 23-24 at the University of Houston in the U.S. By the time Szymanski left the podium, ammonia energy had moved a good distance from the periphery of the [email protected] conceptual map toward its center.
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."
