The U.S. Department of Energy's Office of Science awarded a $200,000 Project Grant to Makel Engineering, Inc., a small business located in Chico, California, to develop a "BIO-GAUGE, Low Cost Biodiesel Fuel Fraction Sensor." This grant, awarded on July 22, 2024 under the Office of Science Financial Assistance Program (CFDA 81.049), supports the company's research and development of an innovative sensor system capable of accurately measuring the composition of biodiesel fuel. Makel Engineering, a Subchapter S Corporation specializing in advanced chemical sensing technologies, will leverage its expertise in microsensor instrumentation, harsh environment detection, and trace gas analysis to create this low-cost biodiesel fuel fraction sensor. The project aims to contribute to broader scientific and technological objectives of the Department of Energy's federal research programs in emerging energy technology domains.
