“…However, overall costs of 0.30 CHF/kWh for synthetic methane from cement based CO2 under the specific Swiss conditions, still is in the range of 0.07-0.42 CHF/kWh reported elsewhere (Brunner and Thomas, 2014;E and E Consultant, 2014;Graf et al, 2014;Ausfelder et al, 2015;Hannula, 2015;Vandewalle et al, 2015). These values strongly depend on the plant scale and technology maturity.…”

The Swiss government has signed the Paris Climate Agreement and various measures need to be implemented in order to reach the target of a 50% reduction in CO2 emissions in Switzerland by 2030 compared with the value for 1990. Considering the fact that the production of cement in Switzerland accounts around 2.5 million ton for CO2 emissions of which corresponds to roughly 7% of the country's total CO2 emissions, the following article examines how this amount could be put to meaningful use in order to create a new value-added chain through CO2 methanation, and thus reduce the consumption and import of fossil fuels in Switzerland. With power-to-gas technology, this CO2, along with regenerative hydrogen from photovoltaics, can be converted into methane, which can then be fed into the existing natural-gas grid. This economic case study shows a cost prediction for conversion of all the CO2 from the cement industry into methane by using the technologies available today in order to replacing fossil methane imports.

“…The electricity-to-fuel efficiency of the electrofuelproduction process strongly depends on the type of electrolyzer and the future development of production technologies. Alkaline electrolysers have efficiencies in the range of 43-69% today, while the most efficient electrolysers are expected to reach efficiencies above 80% based on LHV (Smolinka et al, 2011;Benjaminsson et al, 2013;Grond et al, 2013;Mathiesen et al, 2013;Bertuccioli et al, 2014;Hannula, 2015;Schiebahn et al, 2015). Combining this with the efficiency for fuel synthesis yields electricity-to-fuel efficiencies in the 30-75% range for methane, methanol, and DME, this corresponds to an electricity demand of 1.33-3.33 MWh electricity/MWh electrofuel.…”

“…Different types of energy carriers [e.g., methane, methanol, DME (dimethyl ether), gasoline, and diesel] can be produced, which makes electrofuels a potentially interesting option for all transport modes, especially shipping, aviation, and long distance road transport, where the potential for other renewable fuel options, such as electricity and hydrogen, may be limited. Electrofuels may allow increased use of biofuels, if the CO2 associated with their production is used for production of electrofuels instead of being emitted to the atmosphere (Mignard and Pritchard, 2008;Mohseni, 2012;Hannula, 2015Hannula, , 2016.…”

“…Thus, one can define how the costs differ when building a plant with a different production capacity, as well as the potential changes to the costs linked to lessons learnt . The production cost for an ABP plant has previously been investigated based on simulated processes . The present work is instead based on real cost data from the GoBiGas project, which means that uncertainties related to simulation of the process are avoided.…”

This paper describes an economic analysis of the GoBiGas plant, which is a first‐of‐its‐kind industrial installation for advanced biofuel production (ABP) via gasification, in which woody biomass is converted to biomethane. A previous technical evaluation of the demonstration unit confirmed that it is technically feasible to construct advanced biofuel production plants, using commercially available and widely used components. Thus, significant cost reductions for equipment cannot be expected as a consequence of learning effects. However, the equipment itself accounted for <20% of the total investment cost at GoBiGas and there exists the potential to reduce the production cost through learning how to assemble the process and reduce project‐specific costs. The analysis shows that a plant with capacity of 200 MW of biomethane is an attractive scale for future stand‐alone ABP plants with respect to limiting the production cost. For a 200‐MW ABP plant operated using forest residues as fuel, the production cost for biomethane is estimated at approximately 600 SEK/MWh, (60€/MWh, 75US$/MWh), which is equivalent to 5.4 SEK/liter gasoline [0.54 €/liter, or 2.5USD per gallon (9.9 SEK/€, 8 SEK/USD)], where the feedstock accounts for about 36% of the production cost. The most significant uncertainty factors pertaining to the estimated production costs are expected to relate to: trade conditions; the location of the installation; and the local price of feedstock. Thus, there is some potential for implementing cost‐competitive ABP systems of smaller capacity if low‐grade feedstocks (eg, waste‐derived woody biomass) can be utilized, and/or if the unit can be integrated with the already existing infrastructure.
