Ammonia Energy Live February - 2021

Julian Atchison March 04, 2021

Last week we presented the first episode in our monthly webinar series: Ammonia Energy Live. Every month we’ll explore the wonderful world of ammonia energy and the role it will play in global decarbonisation - with an Australian twist. To kick

The Cost of CO2-free Ammonia

Bunro Shiozawa November 12, 2020

If ammonia is to be introduced into the energy system as a CO2-free fuel, its cost must be at least competitive with that of other CO2-free fuels such as CO2-free hydrogen. In the discussion below I consider the cost aspect

Keynote Speech: Implementation of Ammonia Energy Value Chain

Shigeru Muraki November 14, 2019

Toward low carbon society, it is essential to develop and utilize renewable energies globally. For this challenge, hydrogen energy carriers will take an important role to bridge renewable resources and energy market. Among carriers, ammonia is the most economical and viable option because it has the largest hydrogen content and can be directly combusted without CO2 emissions. Technologies to use ammonia in power generation and industrial markets have been developed in the SIP Energy Carriers in Japan, and The Green Ammonia Consortium established April 2019 is conducting feasibility studies of Green and Blue ammonia and discussing implementation plans for a…

Biomass Based Sustainable Ammonia Production

Antonio SánchezMariano MartínPastora Vega November 13, 2019

The renewable ammonia production is gaining attention nowadays. Current production processes use as raw material, predominantly, natural gas or coal. Therefore, large amounts of greenhouse carbon dioxide are released in the production process. Different alternatives for a sustainable path to produce ammonia have been analysed. One alternative is producing hydrogen through electrolysis, nitrogen by air separation and then produce ammonia via Haber Bosch process (Sánchez & Martín, 2018). An interesting feature of this process is the possibility of integrating renewable energy sources in the ammonia production. Another technology is the electrochemical ammonia production (Bicer & Dincer, 2017). The ammonia synthesis…

Ammonia Production Can be Practically Free

David Judbarovski November 12, 2019

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…
