This Small Business Innovation Research (SBIR) Phase II project aims to develop inexpensive carbon dioxide sensors for heating, ventilation and air conditioning (HVAC) controls. CO2 sensors are now being used to lower heating bills and improve air quality in new commercial buildings, but they have not been widely deployed in retrofits (i.e. A/C replacement), because the sensors are too expensive, and require too much power. In Phase I, Dioxide Materials has demonstrated a new design that requires 3 orders of magnitude less power, and are projected to cost a factor of 5 less than the CO2 sensors used in HVAC today. That will allow CO2 sensors to be used in building retrofits, and residential buildings saving energy, and lowering HVAC costs for a wide range of customers. These sensors use new combinations of catalytic materials that have never been characterized before. Consequently, there are significant scientific challenges in the work including 1)developing novel inks that show high catalytic activity for CO2 activation and can be printed by conventional screen screen printing processes. 2) developing technology to enhance the CO2 permeability through the electrolyte to enhance the measurement speed, 3) developing empirical models of the sensor response that can be used to develop algorithms, and later to be ported
into HVAC design software 4) understanding the effects of the room environment on the sensor response and develop methods to mitigate the response.
The broader impact/commercial potential of this project, if successful, will be to enable affordable control systems. Most HVAC systems are inefficient. They run full blast when buildings are nearly empty, and over ventilate because the air quality in a building is unknown. Several vendors have developed control systems that use CO2 sensors to assess the air quality and adjust the HVAC systems accordingly. Energy savings of up to $0.31/ft2/yr (i.e. $465/yr for a 1500 ft2 house) have been demonstrated, but the systems have
not been widely deployed because the needed CO2 sensors are too expensive. If successful, Dioxide Materials? new sensors will make advanced HVAC control systems affordable. Utility bills will go down. Further, utilities will not need to generate as much electricity, so greenhouse gas emissions will be reduced.

The objective of the proposed work is to create low cost, low power sensors for autonomous measurement of ocean carbon. In our Phase I effort, we showed that Dioxide Materials’ miniature CO2 sensors have the speed and sensitivity to meet NOAA’s requirements for sensing ocean carbon. The objective of the proposed work is to further develop the sensors so that they can be used directly in NOAA’s existing ocean carbon measurement system. Work incudes temperature compensation, so the devices can work in the Arctic, interface changes so the devices can communicate with NOAA’s existing hardware, and other changes. At the end of the program we propose doing a field test at NOAA’s location so we can verify performance for the intended application.

ABSTRACT: The objective of this project is to move an energy efficient process for the conversion of carbon dioxide and water into syngas, a key feedstock for the production of synthetic chemicals. BENEFIT: If we are successful we will have a new process to convert air water and sunlight into transportation fuels. That will result in a domestic source of fuels that does not compete with the food supply . It will also be a route to production of fuels at forward bases, allowing substantial reductions in the logistics burden associated with fuel transport.

Electrochemical devices comprising electrocatalyst mixtures include at least one Catalytically Active Element and, as a separate constituent, one Helper Catalyst. The electrocatalysts can be used to increase the rate, modify the selectivity or lower the overpotential of chemical reactions. These electrocatalysts are useful for a variety of chemical reactions including, in particular, the electrochemical conversion of CO
