Hydrogen Filling Stations: techno-economic analysis of on-site ammonia reforming and H2 purification

This month, a team of researchers from Fuzhou University in Fujian, China, published a new paper in the journal Sustainable Energy & Fuels that provides a “Techno-economic analysis and comprehensive optimization of an on-site hydrogen refuelling station system using ammonia.” The study concludes that “the H2 production cost of the NH3-fed on-site hydrogen refuelling station was at least 15% lower than other carbon-free routes (such as electrolysis, solar thermolysis, photo-electrolysis, etc.), and comparable to that of a methane steam reforming system with carbon capture and storage.”

Ammonia-fueled ships: entering the design phase

Three separate projects to design a range of ammonia-fueled vessels were announced last week at a shipping industry conference in China. Lloyd's Register has granted Approval in Principle (AiP) for the design of a 180,000 ton bulk carrier. ABS announced a project to "produce designs for an ammonia-fueled Chittagongmax container carrier of 2700 TEU capacity." And Lloyd's Register also announced a project for "an ammonia-fuelled 23,000 TEU Ultra-Large Container Ship (ULCS) concept design." All three projects are working with the two-stroke ammonia engine developed by MAN Energy Solutions, and all are led by major shipbuilders in China.

Ammonia in China: change is coming

ANNUAL REVIEW 2019: In the ammonia industry, Chinese data is notoriously hard to verify. Without question, the country produces more ammonia today than any other nation, and yet it has recently closed million of tons of annual capacity. Its cities are smothered in pollution, and its coal-based ammonia plants use the dirtiest technologies available. Huge questions remain. One answer is clear: China has repeatedly proven its desire and ability to become a global leader in developing and deploying clean technologies in the explicit effort to combat climate change. Within China, therefore, the question of large-scale adoption of ammonia energy technologies is increasingly becoming simpler. When?

IEA Completes Two Power-to-Ammonia Reports

The International Energy Agency has completed two reports that examine the economics of hydrogen and ammonia production based on wind and solar electricity generation.  Both reports were written by IEA Consultant Julien Armijo under the supervision of IEA Senior Analyst Cédric Philibert.  One focuses on China and formalizes the findings and conclusions that were the subject of a February 2019 Ammonia Energy post.  The other focuses on Chile and Argentina.  Both reports cast an encouraging light on the near-term cost-competitiveness of green ammonia vs. conventionally produced brown ammonia in specific national markets.

IEA Analysis: Green Chinese P2A Could Compete with Brown NH3

The IEA has developed a rigorous economic model to examine the proposition that resource intermittency can be managed by siting hydrogen facilities where variable renewable energy (VRE) resources have complementary daily and seasonal production profiles. Last month, IEA Senior Analyst Cédric Philibert shared modeling results from selected sites in China with an audience at the Energy Research Institute in Beijing.  The exercise offers a first quantitative look at two important questions.  First, what is the economic impact of "VRE stacking"?  And second, what is the relative cost position of ammonia produced via a stacking approach?
