Natural gas based, ultra-low carbon ammonia without fluegas scrubbing

Reducing the carbon footprint of ammonia is urgent more than ever, and requires new technology innovations to achieve this goal, while keeping these plants competitive and viable. In this session, we will review latest proposed technologies from thyssenkrupp Uhde to achieve ultra-low carbon emissions by implementing a new process flowsheet that replaces the common primary reforming approach and eliminates the need of a fluegas scrubbing system. We will also review the advantages of the new proposed technologies in terms of capex and management of risk associated with new technology implementation.

Demonstration project for a green chemical plant using large-scale alkaline water electrolysis

To achieve the carbon neutrality target set to be accomplished by 2050, hydrogen will play an important role in many sectors such as power, transportation, and industrial applications. Especially in the chemicals and fertilizers sectors, green ammonia, made by utilizing renewable energy as a feed stock, is expected to be materialized, and is also being considered as a hydrogen carrier with the advantage of easier transportation and handling than the hydrogen itself. Hence, in the near future, green chemical production facilities which are fed with hydrogen produced through the use of renewable energy will be installed instead of the conventional…

Low-carbon ammonia at LSB Industries

LSB Industries is the fifth largest ammonia producer in the US and operates three manufacturing facilities in Oklahoma, Arkansas, and Alabama. This year, the company announced its sustainability priorities and two major projects designed to reduce the carbon intensity of its ammonia production. The projects will reduce the companies carbon footprint by over 25% and consist of the construction of a carbon capture and sequestration facility to permanently sequester 450k metric tons of CO2 annually and the retrofitting of an ammonia plant to handle clean hydrogen from eletrolysis which will turn ~15% of the plant production into zero-carbon ammonia. Details…

Ammonia for power generation: a new, efficient, low-emissions generator made possible with software enabled technology and precise flameless reaction control

Customers who have historically wanted to use ammonia for power generation have been limited to co-firing with coal or diesel in order to overcome ammonia’s high ignition temperature and slow chemical kinetics. This process comes at a price; carbon emissions, added costs for blending, and significant drops in power output. Fortunately there is a new and cost effective alternative for ammonia-based power generation, one that’s uniquely positioned to run off of 100% ammonia without any reductions in power or efficiency. Precise reaction control, thanks to software-enabled technology, permits the Mainspring Linear Generator to manage fuel compression ratios and utilize a…

Economic analysis for hydrogen – ammonia decarbonization of a natural gas plant – a phased approach

This paper summarizes a comprehensive technical and economic analysis of a hydrogen-ammonia upgrade to an existing 42 MW natural gas plant. A phased approach is carefully chosen which deploys low-carbon technology in modules which are palatable by large-scale utility customers. The objective is to minimize capital costs of the conversion while maximizing decarbonization as each phase is deployed. A phased approach delivers optionality to utilities which are often locked into carbon-emitting technologies by protracted investment durations. Phase one details implementation of an on-site thermal pyrolysis system. Existing natural gas infrastructure and plant waste heat are used to provide clean hydrogen.…

Program on combustion of ammonia and ammonia-hydrogen mixtures for power generation

GTI Energy and the Electric Power Research Institute (EPRI) have embarked on fundamental and applied investigations of ammonia as an alternative energy carrier under a joint program known as Low-Carbon Resources Initiative (LCRI). Focus is on applications under turbine operating conditions for both ammonia and ammonia-hydrogen mixtures. Participating teams members include the University of Central Florida (UCF), Georgia Institute of Technology and CRAFT Tech. Experimental, conceptual designs of combustors and computational efforts are underway since late 2021 and results to-date will be presented. The presentation will also include expanded tasks related to in-depth pursuit of the topic made possible through…

Ammonia for Green Shipping Corridors

Decarbonization of shipping (responsible for 3% of global greenhouse gas (GHG) emissions) is a complex task due to the scale and complexity of the industry. However, it will not be possible to scale from day one and we need to start somewhere, and this is where Green shipping corridors play and important role. Yara, as the world’s largest ammonia distributor today, is partnering with several players to make this happen. In Scandinavia we have partnered with several players to build a network of ammonia bunkering barges and this summer we also signed a Collaboration Agreement with Pilbara Ports Authority (PPA)…

MAN Energy Solutions 2 stroke Ammonia engine

The marine industry is convinced that Ammonia is not only a very strong candidate as a future fuel, but also that Ammonia will be one of the leading future fuels. MAN Energy solutions has worked since 2019 on the development of a two stroke engine burning Ammonia by using the Diesel principle (as used for other fuels such as Methane , Methanol, Ethane and LPG) In this presentation, we will give an update on the engine design, which we will start testing in Copenhagen in Oct. 2022. The first ammonia engine (with final engine design and combustion process) is scheduled…
