Rendition of HECA Polygen Power Plant with fertilizer production facility.
HYDROGEN ENERGY CALIFORNIA CCS PROJECT (HECA CCS)
On November 6, 2009, DOE announced the signing of a Cooperative Agreement with Hydrogen Energy California, LLC (HECA) under the Clean Coal Power Initiative (CCPI) Round 3 program. With additional funding provided under the Recovery Act, the original DOE funding was $408 million. Along with private capital cost sharing, the HECA Commercial Demonstration of Advanced IGCC with Full Carbon Capture (HECA CCS) project will demonstrate an advanced coal-fired generating plant that co-produces electricity and fertilizer products. SCS Energy acquired the HECA power project from its original developers British Petroleum (BP) and Rio Tinto in May 2011. Due to the expiration of unused funds provided under the Recovery Act in September 2015, the total DOE funding for the project was reduced by approximately $122 million to $286 million. The period of performance for the DOE award ended January 2015, and HECA continues to fund project development independently.
The HECA CCS project will employ integrated gasification combined cycle (IGCC) technology to nominally generate up to 400 MWe (gross) of electricity and produce approximately one million tons per year of fertilizer using a 75 percent sub-bituminous coal and 25 percent petroleum coke fuel blend. The project will enable the capture of CO2 at a rate of approximately 2.6 million tonnes per year.
The HECA CCS project will utilize the Mitsubishi Heavy Industry (MHI) two-stage oxygen-blown gasification technology and combined cycle power block. A Rectisol® acid gas removal system will be employed to achieve the intended CO2 capture efficiency. Water quality and availability issues are addressed by utilizing local brackish groundwater treated on-site to meet all industrial process water requirements. The brackish groundwater will be supplied from the Buena Vista Water Storage District (BVWSD), which is a local water district with some groundwater sources not suitable for agricultural use. The project will also incorporate a Zero Liquid Discharge (ZLD) system. All project wastewater, including wastewater generated from the IGCC, raw water treatment, and cooling tower blowdown will be directed to ZLD system(s) with the recovered water recycled for reuse in the process. This further reduces the water demands of the project.
The project will be located in Kern County, California. Current participants include: MHI and Fluor.
PROJECT DEFINITION PHASE COMPLETED
Phase 1b Project Definition (Pre-FEED) was completed on schedule September 16, 2011 for the HECA project.
FINAL DETERMINATION OF COMPLIANCE ISSUED (AIR PERMIT)
On June 1, 2012, HECA submitted amended air permit and PSD permit applications to San Joaquin Valley Air Pollution Control District and UA EPA Region 9. A Preliminary Determination of Compliance was received on February 7, 2013. The Final Determination of Compliance was issued on July 9, 2013.
DRAFT EIS ISSUED
On June 30, 2013, the Department of Energy and the California Energy Commission jointly released the draft Environmental Impact Statement for the HECA project for public comment.
Delays associated with finalization of the carbon dioxide off-take agreement and other issues are impacting the HECA project. Although the period of performance for the DOE award ended on January 20, 2015, HECA continues to fund project development independently.
