Ammonia production from offshore nuclear power

Samsung Heavy Industries and Danish organisation Seaborg have signed a new agreement to develop floating nuclear power plants. The partners have identified P2X projects producing hydrogen and ammonia fuel as key applications for the 800 MW vessels. This follows a report released in January, where UK-based CORE POWER suggests floating nuclear power to produce offshore ammonia can create a network of strategically-located refueling points to service a wide range of maritime transport, with particularly promising applications in the US.

Ammonia combustion analysis: powertrains, turbines & power generation

This week we explore four updates in ammonia combustion R&D:

1. A team from the University of Cambridge has shown merchant vessels are the strongest candidates for conversion to run on ammonia powertrains, with cargo capacity losses of 4-9% able to be feasibly offset by operators.

2. Researchers at the University of Minnesota have successfully tested a thermochemical recuperation (TCR) reactor to improve the efficiency of a dual-fuel, diesel-ammonia compression ignition engine by minimising ammonia slip.

3. A global team led by Cardiff University researchers has revealed some of the inner workings of ammonia combustion in gas turbine flames.

4. A global team has produced a cradle-to-gate environmental assessment for ammonia production and ammonia-based electricity generation, suggesting that renewable and nuclear ammonia have a significant role to play in decarbonising the power sector.

The Bridge to 100% Nuclear Hydrogen, Enabling Pure Ammonia

My talk will explain what the bridge to 100% nuclear hydrogen is, and how our LWR fleet can be saved by storage and industrial applications like producing Hydrogen at Scale for Ammonia production; and I will walk the audience through the processes and systems available to us, right now, today, to give new life to merchant nuclear and make the way for advanced nuclear. Our storage systems allow for grid balancing and capacity stabilization using excess Merchant LWR nuclear capacity coupled to thermal and pumped storage, and the system would accept otherwise curtailed renewable inputs. With the storage capacity of…

Ammonia: A New Business for Nuclear Energy

Nuclear Energy can be used to support and help decarbonize traditional steam methane reforming and electrolysis to produce hydrogen. Options for integrating nuclear with ammonia, and ammonia derivatives include providing power to an air separation unit to produce nitrogen, and hydrogen combustion to deplete oxygen while providing heat for high temperature steam electrolysis. A comparison of CO2 emissions reduction and costs of urea synthesis indicate there is a strong business case for using nuclear reactors at large and small-distributed ammonia plants. A case for producing 3 tons of ammonia from a 1-MWe power supply will be given.

Terrestrial Energy, National Lab, Southern Company – Partnership Overview Using Integral Molten Salt Reactor Technology with HyS Acid for Hydrogen Production

Demands for safe secure supplies of potable water across the planet are increasing faster than can be provided by natural, ever depleting sources of fresh water. At the same time, world demand for electric power is also accelerating. Making H2 from Natural Gas is not an optimal or efficient process that is also un-economic at higher gas costs. An Integral Molten Salt Reactor (IMSR) is uniquely suited to provide the very high temperatures (585 °C+ working temps.) that are needed to both generate significant amounts of Hydrogen, Oxygen (a feed for industrial oxygen uses) and Electricity needed for advanced economies…

Coupling Integral Molten Salt Reactor Technology into Hybrid Nuclear: Direct Ammonia Production via H2 High Temperature Steam Electrolysis

Demands for safe, secure supplies of potable water across the planet are increasing faster than can be provided by natural, ever-depleting sources of fresh water. At the same time, world demand for electric power is also accelerating. Making H2 from Natural Gas is not an optimal or very efficient process that is also un-economic at higher and erratic gas costs. An Integral Molten Salt Reactor (IMSR) is uniquely suited to provide the very high temperatures (600 °C+ working temps) that are needed to generate both significant amounts of High Temperature Steam Electrolysis (HTSE)-derived Hydrogen & Oxygen (a feed for industrial…

Terrestrial Energy and the Production of Carbon-Free Ammonia

On January 24, the nuclear energy company Terrestrial Energy USA informed the United States Nuclear Regulatory Commission of its plans “to license a small modular, advanced nuclear reactor in the United States.” Many steps later – sometime in the 2020s – the American subsidiary of the Canadian company Terrestrial Energy, Inc., hopes to bring its IMSR technology to market. IMSR stands for integral molten salt reactor. The IMSR stands apart from conventional nuclear technology on several dimensions. On the dimension of operating temperature, the IMSR is hot enough that it can be beneficially integrated with high-temperature industrial processes. According to the company’s research, ammonia production could be a candidate for such integration.
