Tri-State announces clean energy plan, retires coal assets

Trevor Brown January 16, 2020

Yesterday, Tri-State Generation & Transmission Association launched its "transformative" Responsible Energy Plan, which will "dramatically and rapidly advance the wholesale power supply cooperative’s clean energy portfolio." Last week, the utility announced the retirement of its last coal-fired power plants in New Mexico and Colorado. These two announcements provide context for a presentation at the Ammonia Energy Conference in November 2019, entitled Market Integrated Ammonia. Its conclusion — highly relevant for a utility that is closing its coal plants and increasing renewables to 50% by 2024 — is that in a wholesale electricity market with increased volatility, renewable ammonia could be produced at the extremely low cost of $96 per tonne.

Comparative Technoeconomic Analysis of Conventional and Absorbent-Enhanced Ammonia Synthesis

Matthew PalysAlon McCormickEdward CusslerProdromos Daoutidis

Ammonia is the second-most produced synthetic chemical and the main precursor for nitrogen-based fertilizer. In 2015, 160 million tons were produced globally, and global demand is expected to grow 1.5% annually until 2050 [1]. However, traditional ammonia production uses natural gas or coal as its hydrogen source, and as a result, is also responsible for more than 1% of global GHG emissions and 5% of global natural gas consumption [2]. Clearly, a more sustainable ammonia production scheme is needed. One such alternative is obtain hydrogen from electrolysis powered by wind- or solar-derived electricity. It has been proposed to perform this…

Green Ammonia Production Integrated into US Wholesale Power Markets

Shaun Tuyuri

The High Plains and Rocky Mountain regions of the United States have some of the best renewable energy resources in the world. As more non-dispatchable wind and solar generation is integrated into the power system, it is impacting wholesale power markets. Average wholesale electricity power prices are falling while their volatility is increasing. This creates opportunities for large flexible loads that are capable of consuming energy while prices are low and not consuming energy when prices are high. Result from an analysis of dispatchable fully electric ammonia production integrated into the power system are presented.

Ammonia As Hydrogen Carrier to Unlock the Full Potential of Green Renewables

Camel MakhloufiPierre OlivierNouaamane KezibriAlexi Liedes

For decades, grid-scale energy storage has been used to balance load and demand within an energy generation system composed mainly of base load power sources enabling thus to large nuclear or thermal generating plant to operate at peak efficiencies. Energy storage has contributed over the time to meet peak demand and regulate frequency beside peak fossil fuel power plant who usually provided the bulk of the required energy. In the aforementioned context where inherent variability of the power generation asset was mainly a minor issue, energy storage capacity remains nevertheless limited for economic reason storing electricity during low electricity demand…

Our Improved Farm Tractor Ammonia and Hydrogen Fueling System

David Toyne

We have a large farm tractor that is fueled by a mixture of ammonia and hydrogen, or hydrogen alone. We will briefly describe the fueling and ignition improvements that have been made to the engine, and quantify the performance increases. These improvements can be applied to other internal combustion engine applications. This tractor runs only on renewable and CO2 free fuels.

Arpa-E Refuel Program: Distributed Production of Ammonia and Its Conversion to Energy

Grigorii Soloveichik

Ammonia, which has high energy density in easily produced liquid form and can be converted to electric or motive power, is considered to be an almost ideal non-carbon energy vector in addition to its common use as a fertilizer. It can be manufactured anywhere using the Haber-Bosch process, effectively stored, transported and used in combustion engines and fuel cells as well as a hydrogen carrier. Transition from fossil fuels as the energy source and feedstock to intermittent renewable energy sources will require a shift from large scale Haber-Bosch plants (1,000 – 1,500 t/day) to distributed ammonia production matching electrical power…

Ammonia Production Can be Practically Free

David Judbarovski

As a prototype I take Green ammonia: Haldor Topsoe’s solid oxide electrolyzer ( https://ammoniaenergy.org/green-ammonia-haldor-topsoes-solid-oxide-electrolyzer/ ) to produce synthesis-gas (1/2 N2 + 1.5 H2 ) for ammonia production from air, water and renewable energy. The big disadvantage of it is very expensive CAPEX of the electrolyzer consuming 7.2 MWh electricity per a ton of ammonia. In my turn, I suppose a following technology consuming 7.0-7.4 MWh electricity to produce ammonia with by-product of 0.4 ton formaldehyde solution (40% in water) being now USD 300-350/ton fob price, considered as that ammonia payback including CAPEX. The world annual consume of formaldehyde exceeds 10…

Starfire Energy's 10 Kg/Day Rapid Ramp NH3 System Development

Joseph BeachJonathan KintnerAdam Welch

Starfire Energy is building a 10 kg/day NH3 synthesis system using its low pressure Rapid Ramp NH3 process. The system includes hydrogen production by proton exchange membrane electrolyzer, nitrogen production by pressure swing adsorption, NH3 synthesis, and liquid NH3 storage. The tight coupling of the hydrogen, nitrogen, and NH3 processes require minimal reactant buffering. The system design, status, and preliminary performance will be discussed.
