  Title Economic Feasibility of Methanol Synthesis as a Method for CO2 Reduction and Energy Storage Type Journal Article
  Year (down) 2019 Publication Energy Procedia Abbreviated Journal  
  Volume 158 Issue Pages 4721-4728  
  Keywords methanol synthesis  
  Abstract In this paper, a thermo-economic analysis concerning a methanol production plant is performed. In particular, this study was developed with the aim of evaluating the opportunity and viability of obtaining methanol from the chemical reaction between recycled CO2, emitted from a fossil-fuel power station, and hydrogen produced by water electrolysis. This solution can represent an interesting carbon dioxide reduction method and methanol as a product can be considered an energy storage means. As a first step, a thermodynamic analysis is performed in order to determine the mass and energy flows of the plant; then, a feasibility analysis concerning a large size methanol production plant is performed taking into account three different economic scenarios (Germany, Italy, and China). In order to evaluate the economic viability, the total investment cost and payback period are calculated in all the scenarios. Different methanol and electrical energy prices are considered, to take into proper account the influence of these parameters on mid-term future scenarios. Moreover, a sensitivity analysis, considering different oxygen selling prices and PEM electrolyzer capital costs, were performed.

  Title Thermodynamic and Economic Analysis of a Plant for the CO 2 Hydrogenation for Methanol Production Type Journal Article
  Year (down) 2019 Publication E3S Web of Conferences Abbreviated Journal  
  Volume 113 Issue Pages 01013  
  Keywords methanol synthesis  
  Abstract A major goal of politics, society, and industry is the reduction of carbon dioxide (CO 2 ) emissions in order to prevent anthropogenic climate change and an increase in earths temperature. In addition, the expansion of renewable energies and the use of nuclear power, CO 2 capturing (e.g. from exhaust gases), is regarded as a promising strategy to reduce global CO 2 emissions. In this context, the Power-to-X technologies can provide an innovative energy storage concept by combining the main trends of energy systems aiming at high shares of renewable energies, reduction of CO 2 emissions and sector coupling. A promising approach is the production of methanol as a chemical raw material or fuel. The goal of this paper is to present (i) an extensive thermodynamic analysis for the methanol production from carbon dioxide and hydrogen and (ii) an economic analysis for the process based on the thermodynamic studies. The thermodynamic analysis was carried out in the simulation tool Aspen Plus " in order to investigate the impact of the operating temperature and pressure on the performance of the synthesis unit. Based on the thermodynamic results, an economic analysis has been performed in order to define the most feasible solution. For a defined optimal operating temperature, the fixed and operating costs and the methanol production cost were evaluated for different operating pressures. Finally, a sensitivity analysis has been performed in order to define the minimum methanol selling price that allows for a payback period of 10 years for different values of the electrical energy purchasing price.

  Title PEM Water Electrolysis: Innovative Approaches towards Catalyst Separation, Recovery and Recycling Type Journal Article
  Year (down) 2019 Publication International Journal of Hydrogen Energy Abbreviated Journal  
  Volume 44 Issue 7 Pages 3450-3455  
  Keywords Hydrogen,Iridium,Market penetration,PEM water electrolyzers,Platinum,Recycling  
  Abstract We report the development of a facile recycling process for catalyst coated membranes (CCMs) used in polymer electrolyte membrane (PEM) water electrolyzers. After performance evaluation in an assembled electrolysis cell, ultrasonication is used to provide high-yield recovery of not only the noble-metal catalyst materials, but also of the fluoropolymer membrane itself, without the release of hazardous gases. Transmission electron microscopy (TEM) and electrochemical characterization are used to confirm the retention of catalyst particle size, and of the performance of the recycled CCMs. Furthermore, our projections indicate that, if this approach is widely employed, existing resources of noble metals will prove sufficient for the gigawatt-scale implementation of PEM water electrolyzers. This has profound implications for the achievement of current targets for reducing the consumption of precious metals for applications in electrolyzers, fuel cells and other energy storage devices.
