​​​​​Houston based CleanGen LLC is a Clean Energy & Low Carbon Solutions Project Development and Consulting Company with top tier internal EPCm/Technical, Commercial, Regulatory and overall Project Management capabilities.   Our focus is on highly modularized project designs which are based on the best commercially available technologies to reduce energy costs and CO2 emissions.   For over 30 years our team has led and participated in well over 100 Clean Energy and Low Carbon Solutions project evaluations/implementations in the US Gulf Coast, California, Alaska, Midwest, Rockies and Alberta.  

Outlined below are a sampling of our recent projects.  Contact us if you want to know more!


​​Cogeneration:  California​

Construction of two cogens in two California oil fields to provide onsite power and

steam for heavy oil operations.   Both cogens completed in 2017.  CleanGen defined

the projects, performed economic evaluations, performed all EPCm, worked closely

with site owner to obtain all permits/grid power interconnects and managed overall

project from start to finish.







​Cogeneration:  Texas

EPCm for construction of 4-train cogen at Texas Petrochemical facility.











Waste Heat Recovery and CO2 Capture:  Alaska

Techno-economic evaluation of applicable technologies in multiple Alaska

North Slope fields, to:

         1.  Determine best options for reducing energy supply costs

              (waste heat recovery, efficiency), 

         2. Reduce GHG emissions (efficiency and CO2 capture),

         3. Recover CO2/heat from geothermal wells and from oil/water/gas

             production fluids for potential utilization of heat/CO2 in oilfield

             operations. 





CO2 Capture + EOR + Sequestration:  California

​​CleanGen completed detailed CO2 EOR field development design for 200+ MMBO

in place field, in California,  including later final CO2 sequestration.

Feasibility study included comparative design and economics for:

         1. CO2 Gravity Stable / Gravity Drainage scheme ... including nitrogen  chase.

         2. Conventional WAG approach.

CleanGen submitted patent applications for a proprietary oxyfuel based

power and CO2 capture design, as well as completing designs and feasibility

assessments using oxyfuel equipment from other vendors.  Solvent based CO2 

capture options for onsite and offsite CO2 sources were also evaluated.   



Numerous additional studies and projects have been completed including but not limited to those below:


  1. CO2 Capture and Sequestration -- Techno/economic assessment for large independent oil company to capture CO2 from combustion facilities supplying steam to heavy oil recovery operations in California.  The study included installation of onsite cogeneration and CO2 capture facilities where the cogeneration was integrated with existing onsite PV Solar and Direct Access grid power supplies to meet onsite power and steam needs.  Options were developed to sequester the CO2 directly in-field (No CO2 EOR),  or to transport CO2 to a nearby field for use in EOR prior to long term CO2 sequestration. 
  2. CO2 Capture and Sequestration -- Techno/economic assessment for major oil company of several technologies for capture of CO2 from exhaust of turbine and engine cogeneration facilities, for use  in CO2 EOR and CO2 sequestration in the Texas Gulf Coast region.
  3. CO2 Capture and Sequestration -- Evaluated and ranked multiple CO2 EOR + Sequestration projects in the US Gulf Coast, California, Wyoming, Oklahoma, Kansas, West Texas and Canada.  Projects included CO2 supplied from natural sources and from existing industrial facilities with options to sequester the CO2 following EOR.
  4. CO2 Capture and Sequestration -- Identified and ranked multiple targets in the US and Canada for integrated oxyfuel-EOR - Sequestration projects which produced power/steam and provided CO2/N2 supply options for EOR, followed by CO2 sequestration.   Studies included preliminary plant/EOR design, cost and economics.  
  5. Acquisition Due Diligence, CO2 Capture & EOR -- Led topside facilities due diligence for acquisition of two existing EOR companies in North America, which used captured industrial CO2 for EOR.
  6. CO2 Pipeline/Other  Transport -- Techno Economic assessment  and comparison of CO2 transport options from CO2 capture location to CO2 sequestration location.  Options included:  1) acquisition and repurposing of abandoned pipeline;  2) new-build pipeline;  3) early truck and rail transport, following later by pipeline transport. 
  7. Integrated PV Solar and Cogeneration -- Evaluated / Ranked targets for PV Solar / Solar Steam, optionally integrated with Gensets/CHP in California oil fields, taking into account the latest  regulations and incentives. 
  8. Coalbed Methane+Oxyfuel+EOR --  Designed a Coalbed Methane (CBM), development plan to underpin CBM valuation as part of a larger acquisition due diligence effort, including potential use of produced gas for oxyfuel-EOR in nearby oil field.
  9. Waste Heat Recovery+Pipeline Compression Efficiency -- Evaluated design options and related costs/econs for waste heat recovery conversion to power and other use, at several gas compression stations in Louisiana and New York. 
  10. Alternative to Cyclic Steaming in Diatomite Heavy Oil Formation --  Evaluated alternative approaches to current cyclic steam methods for California Diatomite heavy oil recovery,  which can potentially reduce overall energy supply requirements and significantly increase oil recovery without use of traditional frac/other stimulation methods.
