Quantifying the emissions footprint of the nitrogen industry
Presentation

Understanding and quantifying the emissions footprint of an industry is critical to decarbonisation efforts. Without high quality and standardised data, an industry will continually stall on lowering emissions. But this is quickly changing. Companies are seeking to understand their emissions landscape and benchmark themselves accurately. Many leading companies are setting ambitious emissions reduction targets. But its not just the first movers from whom this data matters. Policy is changing as with emissions trading schemes are rolled out across the world. This will force the laggards into action. CRU has developed readily available standardised data and methodologies to capture emissions across…

Hinicio & CertifHy
Presentation

Since 2014, Hinicio is leading CertifHy, the first EU-wide Guarantee of Origin scheme for hydrogen, including a definition for Green Hydrogen and (non-renewable) low-carbon Hydrogen. We will share our experience and provide insights and relevant lessons learned from designing and implementing CertifHy. We will touch upon dealing with multiple primary energies going into a process which might be renewable and non-renewable, and the carbon intensity calculation in multi-input and multi-output plants.

Towards Global Ammonia Energy Certification Standards
Presentation

Considerable attention is now being paid to both life-cycle carbon intensity standards and guarantees of origin for many low carbon fuels, including ammonia energy, to ensure that international trade may be facilitated, expedited, and given priority guarantees of market access under long-term supply agreements. Standardisation and certification are crucial to these markets.  Further, the prospect of commanding a “clean/green” market premium, which buyers in markets such as the European Union and East Asia may be prepared to pay for ammonia energy imports, may also set the necessary impulses to stimulate the domestic ammonia energy economies around the world. Certifications can,…

How to reduce the LCoA of green NH3 with hybrid CSP-PV plants
Presentation

The gNH3 production requires a large amount of renewable energy, where the LCoA is strongly affected by the LCoE. If it is considered only a solar solution, the low Photovoltaic (PV) technology cost can achieve competitive gH2 cost. However, the industrial NH3 plant would require power stability in a 24/7 profile, and a storage solution must be included. In this case, the Concentrating Solar Power (CSP) presents an unique and promising advantage with its dispatchability to fulfill this necessity. Therefore, a hybrid CSP+PV solution can give the best cost solution power mix for the green ammonia industry.

Scaling Up H2 Electrolyzer Technology to Create a Sustainable Future
Presentation

Cummins is a global power leader that designs, manufactures, sells and services traditional and alternative fuel powertrains and powertrain-related components including batteries, electrified power systems, hydrogen generation (electrolyzers), and fuel cell products. As the need to decarbonize industry and mobility becomes clearer, hydrogen needs to rise to scale as a key component of the global energy solution. Processes like ammonia, methanol, refining, other industries, and mobility have been revolutionizing their value chain to meet these climate changing goals. Cummins intends to advance affordable hydrogen production, transport, storage, and utilization to enable decarbonization and market opportunities across these market sectors. “Creating…

The role of green ammonia in sector coupling and seasonal electricity storage
Presentation

Green ammonia (NH3) will have a versatile role in the decarbonisation of large sectors of the global economy. Of these sectors green ammonia will likely have the most competitive potential in decarbonising long-duration energy storage, regional energy and hydrogen transport, shipping propulsion fuel, and replacing existing brown ammonia production for fertiliser and other chemicals. In this presentation, we introduce our modelling on the cross-sector integration of green ammonia into large-scale energy systems, with a case study of India. In the power sector, ammonia may play a role in seasonal storage, system resilience, and electricity import/export. We co-developed the world’s first…

Improving operational safety in ammonia installations by a remote early warning system
Presentation

Accidental releases of ammonia constitute severe risks and common issue of conventional detection systems are the lack of early warning functionality and limited situational awareness. The scanfeld early warning for gas leaks is bridging this gap. Reliable early warning systems for the prevention of major gas releases are crucial for all types of ammonia processing installations and especially new greenfield applications such as energy storage or direct propulsion. The highest possible safety standards are required for a positive public perception and the acceptance of ammonia technologies in general. Our optical remote sensing solution is a particularly suitable method for the…

Optimizing absorption to improve Haber-Bosch synthesis
Presentation

Ammonia absorber columns offer an alternative separation unit to replace condensation in the Haber-Bosch synthesis loop. Metal halide salts can selectively separate ammonia from the reactor outlet gas mixture and incorporate it into their crystal lattice with remarkably high thermodynamic capacity. While the salts’ working capacity can be limited and unstable when they are in their pure form, the capacity is stable and can be high when using a porous silica support. Here, we discuss optimal conditions for uptake and release of ammonia. The production capacity (ammonia processed per unit absorbent and per unit production time) depends on processing parameters…

Dynamic Analysis of Flex-gNH3 – a Green Ammonia Synthesis Process
Presentation

The future of a decarbonised ammonia production is seen as the alignment of the intermittent production of renewable energy, energy demands and ammonia process features. The current Haber-Bosch ammonia synthesis process can indeed be altered to enable green and sustainable ammonia production primarily being driven by renewable electricity. However, this will require to enhance current commercial Haber-Bosch (H-B) process flexibility with modifications to redefine the conventional H–B process with a new optimised control. The technical feasibility of green-ammonia (gNH3) process had been widely discussed and analysed focusing on its energy efficiency, the development of small-scale, distributed, modularised processes that can…

Maritime Ammonia Fuel - Stepping Forward
Presentation

Clearly, by now it is a great understatement to say that ammonia as a maritime fuel has potential or could be developed as an alternative to fossil maritime fuels. Enablers for maritime ammonia fuel are being developed and we have moved past simple potential. In terms of on board technology, supply and other critical areas, maritime ammonia fuel is stepping forward. However, we are only starting out and the road ahead remains long, unclear and of course paved with many potential barriers. We welcome therefore the dedication and quality of work being undertaken by many different entities to help untangle complexity and illustrate pathways. Within…
