“…With such a wide range of estimated capital costs, there is no consensus on the economic feasibility of DAC. For example, Simon et al (2011) argued DAC can be a cost-effective contributor to climate mitigation in the future, while Ranjan and Herzog (2011) found that the costs of DAC systems is prohibitively high compared to other mitigation options.…”

“…At the upper range of these energy requirements, the system only effectively captures CO 2 when a renewable energy source is used. The majority of these studies on the energy requirements of DAC systems, however, are simple energy assessments based on thermodynamic principles and reaction enthalpies instead of outdoor prototypes (House et al 2011, Simon et al 2011, McGlashan et al 2012, Lackner 2013, Wilcox et al 2017.These studies often only include the capture and regeneration step of the DAC systems and thus neglect the energy use from CO 2 transportation and storage. Furthermore, by only analysing energy consumption, emissions due to the production and use of materials and chemicals needed are neglected.…”

“…On the other hand, the reported costs for DAC are relatively higher, in the range of 150 to 300 € per ton [59][60][61][62][63][64] (the amounts reported originally in USD are converted to € at a 1 € to 1.33 USD conversion rate, for the purpose of this work). Climeworks, as a forerunner in this field, expects to reduce the costs to 75 € per ton for large-scale DAC farms [63].…”

In order to achieve targets set by the Paris Agreement and limit global average temperature increase to well below 2 °C above pre-industrial levels, an assessment and a low carbon transformation is needed for all types of human activities. Cement production is associated with high levels of CO2 emissions, with an average of 866 kg of CO2 emitted per ton of cement produced. This positions the cement industry as one of the main sources of anthropogenic greenhouse gas emissions accounting for about 5% of the total, right after the chemical industry and more relevant than the iron and steel industry. About 50% of the emissions are caused by burnt fuel, related transport and other inputs, which can be currently substituted by other measures. However, the CO2 emissions which originate from input limestone cannot be avoided. These process CO2 emissions present a potential for carbon capture and utilisation. This research proposes a global potential analysis of CCU as a possible solution for the CO2 emissions of cement production. Cement CCU may establish a substantial route to use CO2 for synthetic hydrocarbons production and thus contribute towards mitigating the nonsubstitutable CO2 content of the limestone-based raw material. The production of renewable electricity based synthetic hydrocarbon fuels by CO2 captured from cement plants, counts for a potential to produce between 3639 TWhth and 7355 TWhth of liquid hydrocarbons, or 6298 TWhth and 12723 TWhth of synthetic natural gas, or a mix of both at the expected global cement peak production in 2040.

“…The carbon feedstock has to be of biogenic origin [66] or captured from the atmosphere using DAC technologies [67][68][69], to render the fuels GHG-free. The anticipated learning potential as presented by private start-up companies and other sources could lead to average capturing costs below 200, or even 100 Euros/ton of CO 2 captured [57,69], while costs are currently far higher (600-1000 Euros/ton of CO 2 ) [67,68]. Carbon feedstock from biogenic sources proves to be cheaper, in particular when CO 2 is a by-product of another application (biomass used for energy in the paper and pulp industry, biogas upgrading to biomethane, CO 2 capturing in a biomass firing power plant, etc.).…”

Energy System Modelling of Carbon-Neutral Hydrogen as an Enabler of Sectoral Integration within a Decarbonization Pathway

This paper explores the alternative roles hydrogen can play in the future European Union (EU) energy system, within the transition towards a carbon-neutral EU economy by 2050, following the latest policy developments after the COP21 agreement in Paris in 2015. Hydrogen could serve as an end-use fuel, a feedstock to produce carbon-neutral hydrocarbons and a carrier of chemical storage of electricity. We apply a model-based energy system analysis to assess the advantages and drawbacks of these three roles of hydrogen in a decarbonized energy system. To this end, the paper quantifies projections of the energy system using an enhanced version of the PRIMES energy system model, up to 2050, to explore the best elements of each role under various assumptions about deployment and maturity of hydrogen-related technologies. Hydrogen is an enabler of sectoral integration of supply and demand of energy, and hence an important pillar in the carbon-neutral energy system. The results show that the energy system has benefits both in terms of CO2 emission reductions and total system costs if hydrogen technology reaches high technology readiness levels and economies of scale. Reaching maturity requires a significant investment, which depends on the positive anticipation of market development. The choice of policy options facilitating visibility by investors is the focus of the modelling in this paper.
