RAPID: supporting modular manufacturing and process intensification for small-scale ammonia

By on March 04, 2019
Using greener feedstocks at low pressures and temperatures, with higher conversion rates and less greenhouse gases is considered a pipe dream. The technology and equipment simply wasn’t available ... until now. The case for small-scale, energy efficient ammonia production is well documented, but access to funds may not be. Now, Manufacturing USA and the Manufacturing Extension Partnership may offer a new path to success.

Advances in Making High Purity Nitrogen for Small Scale Ammonia Generation

By and on October 31, 2018
The presentation will address recent developments in the Solar Hydrogen Demonstration Project in which hydrogen, nitrogen and ammonia are made from solar power, water, and air; and used to fuel a modified John Deere farm tractor. In industrial applications very pure nitrogen is made by cryogenic distillation of air. Using Pressure Swing Absorption systems alone it is extremely difficult to achieve the required purity. An improved method was developed for making high purity nitrogen, for smaller systems. Will discuss how, when Oxygen contaminates the reactor catalyst, Hydrogen is used to purge the catalyst, and subsequently used as fuel.

Scale up and Scale Down Issues of Renewable Ammonia Plants: Towards Modular Design

By and on October 31, 2018
Renewable sources of energy such as biomass, solar, wind or geothermal just to mention some of the most widely extended are characterized by a highly distributed production across regions (EPA, 2017). Total renewable energy available is more than enough to provide for society needs, but the traditional production paradigm is changing. Economies of scale have featured current industry and its infrastructures based on large production complexes (i.e Dow, Exxonmobil or BASF hubs). The well-known six tenths rule has extensively been used in the chemical industry to scale up or down the cost of technologies. This rule is suitable for large…

Small-scale ammonia production is the next big thing

By on May 11, 2018
Over the last few years, world-scale ammonia plants have been built, restarted, and relocated across the US. The last of these mega-projects began operations at Freeport in Texas last month. No more new ammonia plants are currently under construction in the US, and the received industry wisdom is that no more will begin construction. However, project developers and ammonia start-ups did not get this memo. With low natural gas prices persisting, they have not stopped announcing plans to build new plants. The difference is that the next tranche of new ammonia plants breaking ground will not be world-scale but regional-scale, with production capacities of perhaps only one tenth the industry standard. Despite using fossil feedstocks, these plants will set new efficiency and emissions standards for small-scale ammonia plants, and demonstrate novel business models that will profoundly alter the future industry landscape for sustainable ammonia technologies.

Dutch Initiatives to Store Sustainable Energy in the Form of Ammonia

By on November 1, 2017
Proton Ventures BV is a company dedicated to supply mini ammonia units for storing decentralised produced (sustainable) energy. Proton has developed a commercial unit for the production of small amounts of ammonia, which can store up to 25 MW of power or equivalent (bio-) gas energy. Hans Vrijenhoef, as the director of the company, will give an overview of existing plans in The Netherlands to store this decentralised energy and to make use of this in an economic way. The N-Fuel units will be skid-mounted, safe in operation, and almost fully automated in order to keep CAPEX and OPEX costs…

Developments in Electrochemical Ammonia Synthesis

By and on September 20, 2016
Proton Energy Systems, d/b/a Proton OnSite, is a technology and commercialization leader in the field of membrane based electrolysis. The company was founded on the vision of utilizing electrolysis technology for the capture and storage of energy in high value applications. Recently, the concept of storing electrical energy in the form of a carbon neutral liquid fuel, particularly ammonia, has been gaining traction within the research investment community. Proton has been participating in collaborative research with the University of Minnesota to advance the system concept for distributed ammonia production using wind-derived hydrogen (via electrolysis) and subsequent conversion to ammonia using…

Small Scale Low-Pressure Ammonia Synthesis

By , , and on September 19, 2016
Ammonia is one of the most important chemical commodities in the US and will be a key component in helping the world meet the rising demand for food and energy. Ammonia is needed in distributed locations for agriculture (as fertilizer for small grain and corn production), for indirect hydrogen storage1 (transported as a liquid at moderate pressure to hydrogen stations), or as a liquid fuel2 (for internal combustion engines or solid oxide fuel cells). Recently, there has been significant effort to develop scalable technologies for conversion of intermittent energies (e.g., solar, wind) into energy dense carbon-neutral liquid fuels, and ammonia…
