Approach to cost effective carbon capture from air by producing carbon negative water

Abstract

The invention relates to integrated methods for direct capture of carbon dioxide and water from the atmosphere and their conversion into value-added products in an economical and carbon negative fashion. In one embodiment of the present invention, a portion of the water captured in a DAC process is treated, bottled, and sold as value-added drinking water, thereby offsetting the cost of the capture process. Preferably the drinking water is bottled in low carbon footprint packaging to offer cost benefit while maintaining overall carbon neutrality or negativity. In other embodiments of the invention, a portion of the captured water is split by photovoltaic electrolysis into hydrogen and oxygen as further value-added products. In other embodiments of the present invention, a portion of the captured carbon dioxide is chemically reduced, preferably utilizing hydrogen from the aforementioned photovoltaic-electrolysis process, to produce methanol for use as a carbon-advantaged fuel.
