Hoyt Clarke Hottel Award

Background of Award

Prof. Hoyt Clarke Hottel was in charge of the Godfrey L. Cabot solar energy R&D program at MIT from the late 1930s to the mid 1960s. The Cabot program at MIT involved research on non-biological uses of solar energy by humanity. A parallel program at Harvard involved the use of plants.

Although solar heat collectors of a number of types had already been used in test centers for several centuries, Prof. Hottel and his co-workers were the first to develop accurate analytical models for solar heat collectors. Their modeling and testing work on flat plate collectors led to what is currently known as the Hottel-Whillier model. Original work, by Prof. Hottel and Dr. Byron Woertz, was so careful and precise that in the early 1940s it led to a calibration adjustment in the Eppley pyrheliometer. Prof. Hottel also developed the “utilizability” method for solar energy calculations, invaluable for long term system predictions before computer programs like TRNSYS and F-CHART were available.

On the MIT Cabot program, work was also done on house heating and cooling, selective surfaces, thermoelectrics, solar stills, phase change heat storage, and non-biological photochemistry. Three experimental solar houses were built and tested extensively. Another project of the Cabot team involved the development of lightweight solar stills to provide drinking water to the crew members of US planes shot down over the ocean in World War II.

Prof. Hottel was an extremely dependable and helpful thesis advisor to a large number of BS, MS, and PhD candidates in solar energy and other engineering topics. Sometimes Prof. Hottel forgot how helpful he had been: he paid students compliments on their work, and had to be reminded that he had suggested that approach to begin with. ISES honored Prof. Hottel with the very first Farrington Daniels Award in 1975. MIT honored him by establishing the Hoyt C. Hottel Lectureship in 1985, and the Hoyt C. Hottel Professorship in Chemical Engineering in 1995.

Nomination Information

This award, established by ASES in 2000, was originally set up to recognize accomplishments in the field of solar thermal technologies.  In recent years, this award has shifted its focus to recognize significant contributions in the applications of solar technologies, or tools that support the enabling of solar technologies, resulting in successful commercial endeavors.

The criteria for the 2021 Hottel Award are as follows:

  • The primary requirement is that the recipient has made a significant contribution to the commercialization of a specific solar energy application, or a tool or tools that enable successful solar energy applications.
  • Specific solar applications can include Solar Thermal, Solar PV, Concentrating Solar Power, other solar energy conversion processes, solar heat and power storage technologies, grid integration of variable solar energy, solar resource assessments and forecasting, and analytical models and software tools that enable the application and commercialization of these technologies.
  • Preference will be given to Hottel Award nominees who have demonstrated commercial applications or tools that support the U.S. solar industry.
  • Preference will also be given to Hottel Award nominees who are members of ASES or to individuals or companies who have supported ASES through its conferences, webinars, and publications.

Please include at least two letters of recommendation with your Hottel nomination form, and submit all nomination materials to awards@ases.org.

Nominations for each candidate shall be submitted electronically on the Nominating Form. The nomination form must be submitted by a current ASES member.

Nominations are now closed for 2021.
