Dioxide Materials develops materials for carbon dioxide sensing and remediation. Dioxide Materials is developing carbon dioxide sensors that allow a building's heating, ventilation and air conditioning (HVAC) systems to use less energy, saving money and lowering the building's carbon footprint. Presently buildings are ventilated with outside air to keep the inside air fresh and odor free. The ventilation runs all of the time even when the ventilation is not needed. This wastes energy because the outside air needs to be heated or cooled. Dioxide is building sensors to measure the indoor air quality and determine how much ventilation is needed based on occupancy. Dioxide Materials is also developing processes that convert carbon dioxide into gasoline or synthesis gas, creating a viable source of renewable fuels and a viable energy storage method for wind farms. Dioxide Materials is a leader in the use of artificial photosynthesis and has appeared in such prestigious journals such as Science and Nature Materials and mainstream press including Motor Trend magazine.
