Proud moment - our new article, excellently led by my former MSc student at Aarhus BSS - Aarhus University #BTECH Luc F. Krull (and with Benjamin Sovacool, has been published in #Energy Conversion and Management.
This study, initially Luc's MSc thesis, undertakes both a geospatial analysis and techno-economic assessment within Europe of potential heat sources for direct air capture #DAC.
Helping to provide key insights for siting decisions and coupling with various #renewables, we examine the economic impact of renewable heat
source systems on capture costs of large-scale LT-DAC plants. Among the key questions addressed are: Which geographic locations represent the ideal environment within Europe for each heat source? How do the selected heat sources and geographic locations impact the economic viability of LT-DAC (low-temperature DAC)?
Taking the exemplary cases of Spain, Iceland, Germany, and Norway, we establish that the most promising heat sources varied by country: e.g. Spain for #solar, Iceland for #geothermal, and industrial waste heat and high-temperature heat pumps in both. In contrast, Germany was found to confront lots of environmental and legal barriers.
As a result, there was substantial variation in the levelized costs of #DAC depending on the set-up. The lowest capture costs were associated with #geothermal at 175.63 €/tCO2, followed by industrial waste heat, solar, and high-temperature heat pumps.
We also compare costs with current carbon price levels under the European Emission trading scheme: these fees are not expected to be sufficiently high enough to drive large investments in development and scaling of LT-DAC.
When it comes to carbon capture and storage #CCS, cost levels of #DAC could be comparable, especially if coupled with geothermal energy.
