“…For high-temperature electrolysis (solid oxide electrolysis cell or SOEC) there is hardly any data available on the actual investment costs, especially at sizes of 1 MWel and above, due to the limited amount of installations up to now. The reviewed literature estimates actual costs of 2250-2500 kWel for system sizes of 5-10 MWel [38,48,51], excluding outliers of <600 €/kWel [49,53,54]. For the methanation part the evaluation period was extended to the years 2012-2020, due to the lack of recent relevant data.…”

Projecting cost development for future large-scale power-to-gas implementations by scaling effects

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.

“…These costs are expected to decrease as the scale of the system increases. The cost of hydrogen from electrolysis is somewhat challenging considering the variables involved; however, it is generally agreed that cost of electricity is a major contributor with up to 65% of the cost of hydrogen (James et al, 2016;McDonagh et al, 2018). Clearly, the reduction in electrical energy input and lower cost of electricity can bring a shift change in the cost of electrolysis.…”

A Review on Synthesis of Methane as a Pathway for Renewable Energy Storage With a Focus on Solid Oxide Electrolytic Cell-Based Processes

Environmental issues related to global warming are constantly pushing the fossil fuelbased energy sector toward an efficient and economically viable utilization of renewable energy. However, challenges related to renewable energy call for alternative routes of its conversion to fuels and chemicals by an emerging Power-to-X approach. Methane is one such high-valued fuel that can be produced through renewables-powered electrolytic routes. Such routes employ alkaline electrolyzers, proton exchange membrane electrolyzers, and solid oxide electrolyzers, commonly known as solid oxide electrolysis cells (SOECs). SOECs have the potential to utilize the waste heat generated from exothermic methanation reactions to reduce the expensive electrical energy input required for electrolysis. A further advantage of an SOEC lies in its capacity to coelectrolyze both steam and carbon dioxide as opposed to only water, and this inherent capability of an SOEC can be harnessed for in situ synthesis of methane within a single reactor. However, the concept of in situ methanation in SOECs is still at a nascent stage and requires significant advancements in SOEC materials, particularly in developing a cathode electrocatalyst that demonstrates activity toward both steam electrolysis and methanation reactions. Equally important is the appropriate reactor design along with optimization of cell operating conditions (temperature, pressure, and applied potential). This review elucidates those developments along with research and

“…7 C ). For example, assuming H 2 , O 2 , and electricity prices of $2/kg (33), $0.04/kg (34), and $0.167/kWh [average cost of electricity in California in June 2019 (35)], respectively, a CO 2 price of $83/ton is needed for the proposed plant to break even. This hypothetical price point is lower than previous reports (4, 12–14).…”

SignificanceGlobal warming as a result of rising atmospheric CO2 concentrations is considered an imminent threat to society. In order to address rising CO2 concentrations, effective CO2 capture directly from the atmosphere is likely to be necessary. We integrate direct air capture CO2 and water splitting to produce a mixture of CO2 and H2 via a thermochemical water-splitting cycle. This mixture can, in turn, be used to produce valuable chemicals by known technologies. We demonstrate via experimental investigations and a technoeconomic analysis that the demonstrated integration of the 2 technologies into a single overall process has the potential to become economically favorable in some situations.
