EU policy developments: CBAM & rules for emissions accounting

Julian Atchison July 06, 2022

MEPs have voted to alter the scope of the upcoming Carbon Border Adjustment Mechanism (CBAM) to include hydrogen & ammonia, and for the scheme to cover indirect emissions from manufacture. Meanwhile, two Delegated Acts have established a starting point for rules governing the production of alternative fuels from electrolytic hydrogen, including definitions of “fully renewable” hydrogen and a comprehensive emissions accounting calculation. The European Commission will work with key stakeholders to further clarify and improve the new rules.

Reflections on the last meeting of the Marine Environment Protection Committee: the time is ripe for maritime ammonia

Conor Furstenberg Stott July 04, 2022

To develop sufficient ammonia supply to meet future maritime fuel demands, we face a herculean task. The recent meeting of the IMO’s Marine Environment Protection Committee (MEPC 78) gives us an insight into the key next steps to address financial & regulatory challenges. For the first time, MEPC 78 introduced the idea of a “Zero by 2050” goal for global shipping: a steep change in ambition. The use of funds from mechanisms like carbon pricing to ensure a fair, just and equitable transition, the necessity of high-impact investment to drive the fuel transition, and the adoption of new LCA guidelines in the next twelve months were also discussed. The drive & ambition shown at MEPC 78 indicates that the time is ripe for maritime ammonia to position itself as the fuel of choice for the global shipping industry.

Decarbonizing fossil-based ammonia production in North America

Kevin Rouwenhorst June 22, 2022

Our latest Ammonia Project Features webinar focused on various pathways for decarbonizing fossil-based ammonia production in North America. Blake Adair from Nutrien took us on a tour of some of his organisation’s existing low-carbon ammonia production facilities. He also explained how the technology solutions already exist to drive down emissions from hydrogen production, and improve rates of carbon capture. Dr. Amgad Elgowainy from Argonne National Laboratories then presented his team’s analysis of carbon dioxide mitigation costs for ammonia production, noting that current federal incentives for CCS projects already have a material impact on project costs. With incentives in place and mature technology available, we will soon see more low-carbon ammonia production projects emerge in North America.

Ammonia combustion analysis: powertrains, turbines & power generation

Julian Atchison December 08, 2021

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.

Quantifying the emissions footprint of the nitrogen industry

Chris Lawson

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…

How green are green and blue hydrogen?

Cedric Philibert October 07, 2021

In August, Robert Howarth and Mark Jacobson, respectively from Cornell and Stanford Universities, published “How green is blue hydrogen”, an examination of the lifecycle greenhouse gas emissions (GHG) of blue hydrogen, i.e., hydrogen from steam methane reforming with carbon dioxide capture and storage (CCS). How valid were the assumptions behind the study, were the calculations correct and can a realistic case be argued for blue hydrogen going forward?

Ammonia Energy Live March 2021: event wrap

Julian Atchison April 07, 2021

Last week we presented the second 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. This episode we welcomed Sammy Van Den Broeck, VP Project & Portfolio at Yara Clean Ammonia. Sammy was invited to give his thoughts on the key challenges and opportunities in the global ammonia transition, and explain to us why Australia is so important to Yara's future clean ammonia plans. Interviewing Sammy were Jacinta Bakker (Research Fellow in the MacFarlane Laboratory at Monash University) and Allison Gwilt (Senior Project Engineer, Future Fuels at Origin Energy).

Hydrogen Council publishes Life-Cycle Analysis of Decarbonization Pathways

Trevor Brown February 04, 2021

The Hydrogen Council has published a valuable report with a rigorous life-cycle assessment (LCA) of greenhouse gas emissions from various hydrogen applications. It illustrates the report with eight specific examples, two of which focus on ammonia. With green hydrogen as an input to ammonia used in fertilizer production, we could deliver a 96% reduction in emissions. With blue hydrogen exported and combusted as ammonia for electric power generation, we could deliver an 84% reduction in emissions. As the report states at the start: “Life-cycle emissions are coming into focus with scaling-up of hydrogen … To deliver on the sustainability promise, it is … not only important to make it economically viable, but also maximize its decarbonization potential.”

Certification of low-carbon ammonia: panel wrap-up from the 2020 Ammonia Energy Conference

Julian Atchison January 28, 2021

What are the key considerations that need to be worked through so we can design and implement a certification scheme for low-carbon ammonia that works for a diverse range of stakeholders? On November 17, 2020, the Ammonia Energy Association (AEA) hosted a panel discussion on the topic as part of the recent Ammonia Energy Conference. Not only was it valuable to find out what important players in the ammonia industry want to see in any future certification scheme, but the panel also kicked off a consultation process among AEA members. An audience of around one hundred and fifty producers, end users and researchers all gave their thoughts on what they would like to see in a future scheme, providing a terrific launching point for the AEA Certification Committee to draft, develop and debut a low-carbon ammonia certification scheme.
