Round-trip Efficiency of Ammonia as a Renewable Energy Transportation Media

A new study has made a major addition to the available literature on the economic benefits of ammonia energy. This latest study, published by researchers from CSIRO in Australia, provides the data needed to define the round-trip efficiency of using ammonia as a sustainable fuel and hydrogen carrier.

Optimizing technology pathways for Ammonia Fuel: production, transportation, and use

A paper has just been published by researchers in The Philippines who set out to determine the most environmentally benign way to produce, transport, and use ammonia as a fuel for vehicles.

This new work provides a detailed life cycle analysis of a broad range of ammonia technologies, evaluating both carbon and nitrogen footprints of each, and identifying the optimal "well-to-wheel" pathway. Their results support the idea that using ammonia for energy presents a safe and sustainable way to bring about the hydrogen economy.

Breakthrough Energy Coalition targets carbon-free ammonia

A multi-billion dollar clean energy innovation fund was launched last year, at the Paris climate conference. Led by Bill Gates, the private funding enterprise aimed to develop "groundbreaking new carbon-neutral technologies," without specifying details.

Now, the Breakthrough Energy Coalition is starting work, and one of its initial Technical Quests is to make "Zero-GHG Ammonia Production" a reality.

How to create a market for low-carbon ammonia: product labeling

I wrote last week about ARPA-E's "transformative" ammonia synthesis technologies, describing three technology pathways under development: low pressure Haber-Bosch, electrochemical processes, and advanced electrolysis.

ARPA-E's ambitious R&D program might imply that a meaningful, commercial market for sustainable ammonia is still decades away. It represents, however, only the slow American tip of a fast-moving global iceberg.

In Japan, where there's no debate about climate science, the national effort is already well underway, with three programs to develop low-carbon ammonia synthesis under the Cross-ministerial Strategic Innovation Promotion Program (SIP), 'Energy Carriers.'

Comparative Life Cycle Assessment of NH3 as a Transportation Fuel in Ontario

A recent paper from the University of Ontario Institute of Technology, published in June 2016, provides new data on the relative efficiency and safety of using ammonia as a transportation fuel. It presents a cradle-to-grave "comparative life cycle assessment" for a range of vehicles, encompassing the vehicle cycles (manufacturing, maintenance, and disposal) and the fuel cycle (operation).
