Environmental Impact Analysis on a green ammonia process design in Trinidad & Tobago
Description
Ammonia (NH3) has been investigated as a possible energy source in recent years, with an emphasis on the benefits and difficulties of a fully worldwide deployment from a techno-economic standpoint. The adoption of ammonia as fuel is seen as a technique to help decarbonization; nevertheless, an evaluation of the environmental profile is required to validate the long- term viability of the switch to ammonia as fuel to produce green hydrogen. This paper compares a research report on ammonia synthesis that was based on actual fieldwork using the program Simapro to evaluate the environmental life cycle effects of a green ammonia process. For each of the two ammonia manufacturing processes, a cradle-to-gate evaluation was created. The original ammonia synthesis process has a better global warming potential (GW100a) of 760 kg CO2 eq, abiotic depletion (fossil fuels) of 1.24 x 104 MJ, and ozone layer depletion (ODP) of 6.62 x 10-5 kg CFC-11 eq despite the green ammonia process producing an annual profit of 15,415,891.20 $USD. The traditional ammonia process, which has a lower effect percentage on various categories, is generally preferable over the green ammonia process, according to an LCA completed for this research.
