Advanced Combustion Technologies

The California Energy Commission (CEC) is gathering information to inform a solicitation for a future solicitation on oxygen-enriched combustion and would appreciate your responses to the following:

1. The following will help us target our specific research:

  1. What are major barriers (technical, economical, and other) for wide adoption of oxygen-enriched combustion?
  2. What are examples of research that could eliminate barriers to wide adoption of oxygen-enriched combustion?
  3. What are examples of current or past projects involving oxygen-enriched combustion? What are important lessons learned from these projects?
  4. What California industries could benefit most from oxygen-enriched combustion?
  5. What are technical challenges that could result from higher oxygen content and higher combustion temperature (e.g., increased NOx emissions; accelerated degradation of materials in burners, furnaces, kilns)?
  6. Provide examples of existing projects using centralized oxygen generation, distribution via pipeline networks or other approaches that could benefit from R&D.

2. The following will help us establish performance metrics and technology status in California:

Besides cryogenic separation, pressure/temperature swing absorption, ion transport membranes, are there any other promising technologies that should be considered?

  1. For the technologies listed in item 2a:
    • What is the estimated energy requirement to produce oxygen at the following capacities: 1 metric ton of oxygen per day, 25 metric tons per day, 100 metric tons per day
    • What is the estimated capital and operational costs for 1 metric ton per day of oxygen production capacity?
  2. Identify California research teams working on oxygen-enriched combustion.
  3. Identify California companies who develop and sell equipment for oxygen production and oxygen-enriched combustion.

Innovative Waste Heat Recovery Technologies

Program Area: Industrial, Agriculture and Water

Description:  The California Energy Commission seeks information on innovative waste heat recovery technologies to inform future research initiatives and solicitations aimed at reducing natural gas use and greenhouse gas emissions in the industrial sector. We are interested in answers to the following:

  1. What California industries have large volumes of ultra-low (<250º F) or ultra-high temperature (>1,600º F) waste heat?
  2. What research is needed on advanced technologies or materials (including coatings) for recovering waste heat cost effectively in ultra-low heat or ultra-high temperatures?
  3. Should research focus primarily on the ultra-low or ultra-high temperature waste heat or, if not,  what other temperature ranges?
  4. What advanced heat recovery technology improvements are needed to increase wide spread deployment by industry?
  5. What are the cost and technical targets that must to be met to drive customer adoption (such as minimum rate of return or minimum percent heat recovery)?
  6. What complementary technologies and approaches can be combined to increase the value proposition of waste heat recovery systems?

Please submit responses to the Energy Commission docket 19-ERDD-1. Responses must be submitted by 5:00 p.m. on August 6, 2019.
