Techno-economic and life cycle greenhouse gas assessment of green ammonia produced by low-pressure Haber-Bosch process

open access: yesEnergy Nexus
Green ammonia can be used as an energy storage carrier and a sustainable chemical. To improve the competitiveness of green ammonia, two power-to-ammonia (PtA) processes integrated with low-pressure (LP) and ultra-low-pressure (ULP) Haber-Bosch (HB ...

(Ru-)Mo2C (MXene) catalysts for ammonia synthesis: From Haber-Bosch to chemical looping processes

open access: yesMaterials Today Catalysis
This study investigated (Ru-)Mo2C (MXene) materials for ammonia thermo-catalytic synthesis under atmospheric or moderate pressure. Under a H2-N2 (3:1) flow, the Mo2C MXene phase showed limited activity in ammonia synthesis at atmospheric pressure at 400 °

The Haber Bosch–harmful algal bloom (HB–HAB) link

open access: yes, 2014
Large-scale commercialization of the Haber–Bosch (HB) process is resulting in intensification of nitrogen (N) fertilizer use worldwide. Globally N fertilizer use is far outpacing that of phosphorus (P) fertilizer. Much of the increase in N fertilizers is

How does a resilient, flexible ammonia process look? Robust design optimization of a Haber-Bosch process with optimal dynamic control powered by wind

open access: yesProceedings of the Combustion Institute, 2022
Ammonia can be an essential energy vector for storing excess renewable energy during the year and release this energy when demand is high. This storage during the year provides an essential part in the energy sector for moments when there is not enough ...

Beyond Soil Inoculation: Cyanobacteria as a Fertilizer Replacement

open access: yesNitrogen, 2023
Nitrogen-fixing bacteria such as cyanobacteria have the capability to fix atmospheric nitrogen at ambient temperature and pressure, and intensive cultivation of cyanobacteria for fertilizer could lead to its use as an “environmentally friendly ...

High-throughput screening of suitable nitrogen carriers for chemical looping ammonia synthesis

open access: yesApplications in Energy and Combustion Science, 2023
Chemical looping ammonia synthesis is a promising pathway to synthesise ammonia with lower energy and economic costs than the current Haber-Bosch process, for example, by lowering the operating temperature and/or pressure, whilst maintaining comparable ...
