“…Similar results could be reached using high-temperature electrolysis [6]. For the production costs of synthetic methane, Gorre et al [7] tried to identify optimized PtG plant operation scenarios according to gas selling strategies and electricity purchase. Presuming significant reductions for CAPEX and OPEX of PtG plants, methane production costs could reach 50-90 €/MWhSNG by 2030 and 25-65 €/MWhSNG by 2050, under optimal conditions for plant scales of 10 MWel.…”

Power-togas (PtG) is widely expected to play a valuable role in future renewable energy systems. In addition to partly allowing a further utilization of the existing gas infrastructure for energy transport and storage, hydrogen or synthetic natural gas (SNG) from electric power represents a high-density energy carrier and important feedstock material for further processing. This premise leads to a significant demand for large-scale PtG plants, which was evaluated with an amount of up to 14.2 TWel at a global scale. Together with the upscaling of single-MW plants available today, this will enable to achieve appropriate cost reduction effects through technological learning. These effects were evaluated in the present paper via a holistic techno-economic assessment of different PtG plant configurations, resulting in the reduction of SNG production costs down to 100 €/MWhSNG by 2030 and below 60 €/MWhSNG by 2050, according to the supplying electricity source.

“…Sibai et al optimized the reactor section of the Sabatier process in an attempt to reduce the SNG production cost [10]. An overview of the production costs of SNG in 2030 and 2050 is provided by Gorre et al [11]. They reported that the production costs are mainly influenced by electricity prices and the operating hours of the electrolyser and methanator [11].…”

The volatile nature of the renewable energy sources requires energy storage to compensate for the imbalances and to provide reliable base load. Power-to-Methane technology facilitates long-term high capacity renewable energy storage in the form of Synthetic Natural Gas (SNG) in the gas network. Unlike hydrogen, SNG usage in the network has no restrictions and natural gas appliances can operate on SNG. The two inputs required to produce SNG in the methanator are hydrogen and CO 2 and they can be obtained from several sources. This leads to multiple possible process flow configurations in SNG production, each of them with varying performance. An optimization model has been developed in GAMS to analyse the performance of these various configurations. The objective of this research is to determine the optimal configuration, key cost factors and their effects on the production cost to identify the areas that require further development for cost reduction. This work also aims to determine the production cost per unit of SNG and the factors with most significant influence on the production cost by implementing a factorial design and a multivariate analysis (analysis of variance) approach. Methanator, electrolyser, biogas upgrader and hydrogen storage are considered as the fundamental process units in this work. The lowest production cost identified in the first year of production is 0.432 €/kWh SNG. The discounted production cost obtained shows that the lowest cost in 20 years from now is 0.143 €/kWh SNG. The variable with the most influence on the production cost is the capex of the methanator followed by the capacity of the methanator.

“…Indeed captured CO 2 can be transformed from a waste to a raw material and act as the building block molecule for the synthesis of organic compounds, with the primary focus of synthesizing biofuels but also biochemicals. A number of different processing routes have been proposed including the catalytic hydrogenation of CO 2 to methanol and olefins (Pérez-Fortes et al, 2016), SNG (Gorre et al, 2019), diesel (Dimitriou et al, 2015), and jet fuels (Willauer et al, 2012), to name a few. However, capturing CO 2 in industrial processes is responsible for around 75% of the overall cost of carbon capture and storage (Olajire, 2010).…”

Wastewater treatment and sludge disposal are responsible for considerable costs and emissions in a global scale. With population and urbanization growing, tackling the rational and efficient use of energy while fulfilling the desired effluent standards are imperative. In this work, a superstructure-based approach is designed to incorporate alternative treatments for wastewater. In particular, technologies like hydrothermal liquefaction and gasification, coupled with technologies for CO 2 conversion to value-added products are studied. Multi-objective optimization is applied as a way to generate multiple solutions that correspond to different system configurations. From a reference treatment cost of almost 0.16 $/m 3 WW , an environmental impact of 0.5 kgCO 2 /m 3 WW and an energy efficiency of 5%, different configurations are able to transform a waste water treatment plant to a net profit unit, with a net environmental benefit and energy efficiency close to 65%. The investment in hydrothermal liquefaction producing biocrude coupled with catalytic hydrothermal gasification demonstrated to yield consistently better total costs and environmental impacts. Parametric analysis is performed in the inlet flow of wastewater to account for different sizes of waste water treatment plant, with smaller inlets achieving values closer to those of the state-of-the-art configuration.
