“…Environmental parameters are required to be controlled by a long-term monitoring program along the whole storage life-cycle, and energy and economic parameters depend on the location, size and site specific characterization of the storage project. Depending on the regional conditions and the technical parameters of the project, the resulting additional expenses for CO 2 conditioning and storage are indicated in the literature within cost bandwidths (Chen and Morosuk, 2021;Smith et al, 2021).…”

In its latest assessment report the IPCC stresses the need for carbon dioxide removal (CDR) to counterbalance residual emissions to achieve net zero carbon dioxide or greenhouse gas emissions. There are currently a wide variety of CDR measures available. Their potential and feasibility, however, depends on context specific conditions, as among others biophysical site characteristics, or availability of infrastructure and resources. In our study, we selected 13 CDR concepts which we present in the form of exemplary CDR units described in dedicated fact sheets. They cover technical CO2 removal (two concepts of direct air carbon capture), hybrid solutions (six bioenergy with carbon capture technologies) and five options for natural sink enhancement. Our estimates for their CO2 removal potentials in 2050 range from 0.06 to 30 million tons of CO2, depending on the option. Ten of the 13 CDR concepts provide technical removal potentials higher than 1 million tons of CO2 per year. To better understand the potential contribution of analyzed CDR options to reaching net-zero CO2 emissions, we compare our results with the current CO2 emissions and potential residual CO2 emissions in 2050 in Germany. To complement the necessary information on technology-based and hybrid options, we also provide an overview on possible solutions for CO2 storage for Germany. Taking biophysical conditions and infrastructure into account, northern Germany seems a preferable area for deployment of many concepts. However, for their successful implementation further socio-economic analysis, clear regulations, and policy incentives are necessary.

“…Developing transport infrastructure and storage sites is capitally intensive and significant economic advantages can occur at larger scales. [78][79][80] Hence, it is unlikely that the infrastructure would be dedicated to a singular DAC plant. Instead, the infrastructure for the transport and storage supply chain needs to be developed independent of a specific DAC plant.…”

Direct air capture and storage is a technological solution to removing CO2 from our atmosphere that is deemed necessary to reach climate targets. However, huge question marks remain over the current and future costs. Here, we show the cost of DACS, for four example technologies, of plants built today before we project these costs into the future using technological learning theory. We exhibit that the costs of the first plants will be higher than many figures quoted today, but long-term, this can reduce to $80-600 t-CO2-1 at the Gt-CO2 year-1 technology scale. We also show that intelligent deployment via siting and energy source selection is critical and can save a few thousand dollars per t-CO2-1 for some technologies. Finally, we explore which policies can help create a market, accelerate scale-up, and reduce the long-term costs of direct air capture as a potentially vast future industry.

“…The authors do not account for biogenic emissions, so a 57% fraction was assumed (median value of the range reported by Rosa et al, 2021). One other modification to the data of Tang and You is the additional cost of CO 2 transport and storage, assumed to be $16/tCO 2 based on the transport and storage cost tiers identified for China by Smith et al (2021). The relevant cost values are displayed in Table 2, and the carbon emissions balance is displayed in Table 3.…”

“…Power demand for the conversion process (shown in Table 5) is based on Larson et al (linearly scaled as described for CAPEX), while the power demanded by CO 2 capture and H 2 liquefaction processes are calculated using equations given by Baker et al Any power needs are initially satisfied by the power produced via the gasification process, and necessary excess power is taken from the grid. The cost of transporting the compressed CO 2 100 miles is estimated to be $5/tCO 2 for the FT fuel process and $4/tCO 2 for the hydrogen processes based on cost curves from Smith et al (2021) (where the latter case is cheaper per ton because more CO 2 is transported). Injection costs are assumed to be $11/tCO 2 (Psarras et al, 2020).…”

In the context of climate mitigation, biomass has traditionally been viewed as a means to deliver low-carbon energy products. Adding carbon capture and sequestration (CCS) to a bioenergy production process can yield net-removals of CO2 from the atmosphere, albeit at an increased cost. Recently, the Aines Principle was established, stating that at some carbon price, the revenue generated from CO2 removal will exceed the revenue generated from energy production from a given bioconversion process. This principle has only been illustrated for the theoretical conversion of a non-specific biomass source, and has not yet been demonstrated to show real carbon prices that can tip the scale for biomass carbon removal to be more economically favorable than bioenergy production. In this study, we demonstrate the Aines Principle at work in two specific examples of biomass conversion. The first case involves a Chinese municipal solid waste incineration plant, with and without CCS. The second case compares using forestry residue solely for energy production (via gasification), solely for carbon removal (via burial) or both. By comparing the energy and carbon revenue streams under a range of carbon prices, we show that carbon removal revenue can exceed energy revenue at currently available carbon prices below $200/tCO2.
