Start of the Journey – A Carbon Capture Success Story

Carbon Capture, Utilization and Storage (CCUS) has proven to be an important and effective step in helping organizations achieve their global climate change goals. This presentation will provide an overview of a strategic success story, highlighting the importance of partnering with key stakeholders, taking a concept and turning it into an operational reality.

The Clean Ammonia Transition @ Yara

Yara is one of the world’s largest ammonia producers, and the largest trader and shipper of ammonia around the world. We see green ammonia as key molecule to decarbonize the food chains, as well as the ultimate zero-carbon shipping fuel. To provide proof of concept, different large commercial demonstration projects are in the pipeline. The green projects are based on hydro, off-shore wind and solar, while solutions for blue and grey ammonia can be suitable during the transition period. Several framework conditions for success will be discussed.

CF’s Commitment to Clean Energy Economy – Clean Fuels for a Sustainable World

Hydrogen has emerged as a leading clean energy source to help the world achieve net-zero carbon emissions by 2050. Ammonia is one of the most efficient ways to transport and store hydrogen and is also a fuel in its own right. CF is the world’s largest producer of ammonia and is uniquely positioned, with an unparalleled asset base and technical knowledge, to serve this anticipated demand. We are announcing our commitment to decarbonize the world’s largest ammonia production network, positioning CF at forefront of clean hydrogen supply. We have also announced a new green ammonia project at our Donaldsonville Nitrogen…

De-carbonization of Ocean-going Vessels

Most of world trade is supported by ships. In fact, nearly 200 times cargos are carried by ships than air. And, about 800 million tons of CO2 are emitted in the world ocean by whole shipping industry every year. NYK Group as one of the world’s leading marine transportation company is committed to our efforts for GHG emission reduction. We are operating over 700 ocean-going vessels.

Ammonia Energy Scale-up challenge

Yara was founded in 1905 to solve famine in Europe, through the production of mineral fertiliser from renewable energy. Today’s challenges have not changed and Yara’s mission is to responsibly feed the world and protect the planet. Producing renewable ammonia has been done before, and the transitional cost and CO2 gap can be closed in public-private partnership. Yara recognizes that collaboration and innovation along the value chain is essential to move into the future, reducing emissions in agriculture (digital farming, circular economy and nitrate-based products). Being one of the largest ammonia producers and the truly global leader in ammonia supply…

Ammonia as a fuel – building the business case

The successful substitution of current fossil-based fuels by zero-carbon energy sources is dependent on a combination of policy / regulation, investment and commercial business model development and fuel / technology development that will evolve over the coming years. The evolution of both the energy system and the shipping system that is needed, and associated timescales of development, investment and asset life, means that there are steps that need to be initiated now, and work carried out throughout this decade, even though the transition may not be completed for a couple of decades. This presentation looks at the Technology readiness, investment…

Alternatives to Ammonia Synthesis: An Electrochemical Haber-Bosch Process

Several alternatives to the existing process for ammonia synthesis, the Haber-Bosch Process, have been proposed in the past two decades, including the electrochemical synthesis in aqueous, molten salt or solid electrolyte cells. The present work reviews results of recent efforts (last 3 years) for the electrochemical synthesis of ammonia. An Electrochemical Haber-Bosch Process is also demonstrated. The proposed BaZrO3 – based protonic ceramic membrane reactor combines hydrogen production via the reactions of methane steam reforming and water-gas shift at the anode (Ni-composite) with ammonia synthesis from N 2 and protons (H + ) at the cathode (VN-Fe). Hydrogen extraction from…

Electrification of Ammonia Synthesis

Near-term prospects for decarbonized ammonia synthesis rely on conventional thermochemical Haber Bosch coupled to either electrochemical hydrogen production or methods of mitigating carbon emissions, such as carbon capture and storage. Thermochemical Haber Bosch requires high temperatures to achieve significant rates of ammonia synthesis and high pressures in order to achieve reasonable conversions of nitrogen and hydrogen to ammonia. Next-generation electrically-driven routes raise the prospect of using voltage in the place of temperature and pressure – an ambient pressure and room temperature route through which renewable electricity can be used to convert nitrogen and hydrogen to ammonia. Electrically-driven routes for nitrogen…

Whither Aqueous Electro-reduction of Nitrogen to Ammonia?

Electrochemical reduction of N 2 (NRR) is widely recognised as an alternative to the traditional Haber-Bosch production process for ammonia. The high-energy efficiency, low-cost variant of this process involves an aqueous electrolyte and there is now a substantial literature on this topic. However, though the challenges of NRR experiments have become better understood, the reported rates in these aqueous solution studies are often too low to be convincing that reduction of the highly unreactive N 2 molecule has actually been achieved. Unfortunately, there are many possible impurity sources that can interfere with robust measurements. In this presentation we will discuss…
