“…[18][19][20] There are numerous existing materials and millions of hypothetical ones that can be generated in silico to be explored for DAC applications. [111][112][113][114][115] Their properties (e.g., density, solubility, permeability, volatility, viscosity, porosity, heat of absorption, heat of adsorption, thermal conductivity) cover a broad design space, making their exploration challenging (#1). Further materials research could help reduce the energy consumption or increase CO 2 removal efficiency (#2).…”
