This paper aims to present a pre-feasibility study of power-to-fuel plant configuration designed for the production 500 kg/h renewable methanol (e-methanol) from green hydrogen and captured carbon dioxide. Hydrogen is obtained by water electrolysis employing overproduction electricity. Carbon dioxide assumed be separated flue gas conventional power station means an amine-based CO2 absorption system. A comprehensive process model has been developed with support Aspen Plus tool simulate all sections overall After optimization, detailed economic analysis – based on capital operating costs derived commercial-scale experience assuming 20-year lifetime performed calculate levelized cost (LCoM) 960 €/t (about 175 €/MWh). The confirms that, today, technology still not competitive point view, being LCoM more than double current price in international market (450 €/t). However, it indicates that expected become mid-term future, as consequence new European policies. also reveals mainly affected electricity electrolyser cost, well capacity factor plant.

A Prompt Decarbonization Pathway for Shipping: Green Hydrogen, Ammonia, and Methanol Production and Utilization in Marine Engines

Atmosphere, Journal Year: 2023, Volume and Issue: 14(3), P. 584 - 584

Published: March 17, 2023

The shipping industry has reached a higher level of maturity in terms its knowledge and awareness decarbonization challenges. Carbon-free or carbon-neutralized green fuel, such as hydrogen, ammonia, methanol, are being widely discussed. However, little attention paid to the fuel pathway from renewable energy shipping. This paper, therefore, provides review production methods for power (green methanol) analyzes potential application shows that methanol (1) hydrogen seawater electrolysis using power; (2) ammonia + Haber–Bosch process; (3) CO2 power. While future is bright, short term, costs expected be than conventional fuel. Our recommendations therefore follows: improve technology reduce cost; develop electrochemical increase efficiency production; explore new technology. Strengthening research development expanding capacity ensure an adequate supply low- zero-emission marine important factors achieve carbon reduction

This research was motivated to address limitations in the current lifecycle assessment frameworks with absence of proper guidelines for developing default values energies consideration supply chain activities and maritime transportation. Given this, it aims evaluate level life cycle GHG emissions heavy fuel oil, LNG, LPG methanol as marine fuels produced supplied energy import-dependent countries, using South Korea a case study. The analysis clearly shows that impact international shipping on Well-to-Tank (WtT) carriers would be subject several factors: propulsion system types, quantify transported, routes distances voyages. For instance, transportation from LNG vary significantly depending country import, ranging 2.26 g CO2 eq./MJ (representing 12.2 % Malaysia) 5.97 33.3 WtT Qatar). As preliminary study, an enhancement quality input/inventory data is imperative obtaining reliability results. Nevertheless, comparative different stages provides valuable insights stakeholders develop effective policies refueling plans reducing fuels. These findings could also enhance regulatory framework provide meaningful carbon footprints importing countries. study results strongly suggest emission countries relying imports via transport should further developed regional differences, such distance, successful arrival LCA application industry.
