Advanced Hydrogen Compressor for Hydrogen Storage Integrated with a Powerplant

This report summarizes work performed by Siemens Energy (SE) to design, build and test an advanced hydrogen compressor stage suitable for use in a hydrogen electrolysis system integrated with a powerplant to achieve energy storage in the form of compressed hydrogen. As hydrogen utilization increases to achieve energy storage and decarbonization of a variety of industries, the need is growing for improved and more cost-effective hydrogen compression technologies. The counter-rotating compression stage concept demonstrated under this contract and presented in this report offers a novel approach to achieve significantly more head rise per stage of compression, resulting in the potential for decreased capital cost and footprint compared to current state of the art centrifugal compression technologies. This report includes details of the design, testing, results, and subsequent validation of aerodynamic performance predictions.

LP CO 2 Compressor Final Technical Report

This report summarizes work performed by Dresser-Rand, A Siemens Business and subcontractors, under DOE award number DE-FE0026727, in pursuit of the design, construction and test of a 10:1 pressure ratio “Low Pressure” (LP) supersonic CO 2 compressor suitable for use as a first stage in a two stage 100:1 compression system. This LP compressor, in conjunction with a corresponding 10:1 high pressure compressor, provide the overall 100:1 compression ratio required to compress CO 2 from 22 psia (as generated by a CO 2 capture system) to the 2215 psia required to transport CO 2 via a pipeline to a suitable sequestration site. The compressor demonstrates application of Dresser-Rand’s supersonic compression technology at an industrial scale using CO 2 in a closed-loop testing facility. This scope of this technical report is to summarize all phases of the program executed from August 5, 2015 to the June 30, 2018. This program included the final testing of a “high pressure” (HP) compressor that had previously been built by Dresser-Rand and the design, fabrication, assembly and test of a corresponding LP compressor. In summary, the LP compressor exceeded the target pressure ratio and efficiency goals for the program at CO 2 flowrates suitable for those expected in coal fired power plant carbon capture systems. Initial and Final Techno-Economic Analysis reports were generated to show the value this compression solution brings to carbon capture and sequestration (CC&S) systems for the Case B12B coal fired power plant model. Integration of the DATUM S compression technology into a carbon capture and sequestration system was shown to result in a 27% reduction in the Cost of Electricity for the compression system, as well as a 21,500 gallon per hour reduction in required cooling water flow for the plant.
