The Department of Energy, Office of Nuclear Energy, has requested that a Hydrogen Technology Down-Selection be performed to identify the hydrogen production technology that has the best potential for timely commercial demonstration and for ultimate deployment with the Next Generation Nuclear Plant (NGNP). An Independent Review Team (IRT) has been assembled to execute the down-selection. This report has been prepared to provide the members of the Independent Review Team with detailed background information on the High Temperature Electrolysis (HTE) process, hardware, and state of the art. The Idaho National Laboratory has been serving as the lead lab for HTE research and development under the Nuclear Hydrogen Initiative. The INL HTE program has included small-scale experiments, detailed computational modeling, system modeling, and technology demonstration. Aspects of all of these activities are included in this report. In terms of technology demonstration, the INL successfully completed a 1000-hour test of the HTE Integrated Laboratory Scale (ILS) technology demonstration experiment during the fall of 2008. The HTE ILS achieved a hydrogen production rate in excess of 5.7 Nm 3 /hr, with a power consumption of 18 kW. This hydrogen production rate is far larger than has been demonstrated by any of the thermochemical or hybrid processes to date.This report was prepared in April-May 2009 specifically for the IRT, which at the end of its evaluation in July 2009, recommended that:DOE-NE should focus on the continued development of HTSE [High Temperature Steam Electrolysis] as the leading candidate for integration with NGNP in 2021. This conclusion is based upon the IRT judgment that HTSE has the highest probability of meeting the down-selection criteria described in the report, including efficient production of hydrogen at NGNP conditions.

“…Results were presented for the electrolysis of both steam and carbon dioxide separately. Recently, renewed interest in energy storage through hydrogen and syngas (synthesis gas, H 2 and CO) production has led to increased research into reversible SOFC and specific SOEC studies [3][4][5][6]. The production of high quality hydrogen as a means of energy storage for nuclear power has also recently been considered as a viable option [7].…”

“…Most of the materials selected for SOECs are those that have been in use in traditional SOFCs. Potential cathode materials include Ni-YSZ ceramic-metallic (cermet), samarium-doped ceria, and recently various LSCM (lanthanum strontium chromium manganite) doped perovskites [3,8]. Anode materials considered are LSM (lanthanum strontium manganite), LSF (lanthanum strontium ferrite), or LSCo (lanthanum strontium cobaltite), all combined with the electrolyte material [9].…”

This LDRD involved a collaboration between Sandia and the Colorado School of Mines (CSM) ins solid-oxide electrochemical reactors targeted at solid oxide electrolyzer cells (SOEC), which are the reverse of solid-oxide fuel cells (SOFC). SOECs complement Sandia's efforts in thermochemical production of alternative fuels. An SOEC technology would co-electrolyze carbon dioxide (CO 2 ) with steam at temperatures around 800 ºC to form synthesis gas (H 2 and CO), which forms the building blocks for a petrochemical substitutes that can be used to power vehicles or in distributed energy platforms. The effort described here concentrates on research concerning catalytic chemistry, charge-transfer chemistry, and optimal cell-architecture. technical scope included computational modeling, materials development, and experimental evaluation. The project engaged the Colorado Fuel Cell Center at CSM through the support of a graduate student (Connor Moyer) at CSM and his advisors (Profs. Robert Kee and Neal Sullivan) in collaboration with Sandia. 4 ACKNOWLEDGMENTSThis report is based largely upon the thesis written by Connor Moyer for his degree of Master of Science (Engineering) at Colorado School of Mines, which this LDRD helped fund. This project also leveraged modeling results from Dr. Huayang Zhu at Colorado School of Mines, who was primarily funded by the Office of Naval Research via an RTC grant (N00014-05-1-03339).5

Conceptual design of ammonia‐based energy storage system: System design and time‐invariant performance

2017

in Wiley Online Library (wileyonlinelibrary.com)Chemicals-based energy storage is promising for integrating intermittent renewables on the utility scale. High roundtrip efficiency, low cost, and considerable flexibility are desirable. To this end, an ammonia-based energy storage system is proposed. It utilizes a pressurized reversible solid-oxide fuel cell for power conversion, coupled with external ammonia synthesis and decomposition processes and a steam power cycle. A coupled refrigeration cycle is utilized to recycle nitrogen completely. Pure oxygen, produced as a side-product in electrochemical water splitting, is used to drive the fuel cell. A first-principle process model extended by detailed cost calculation is used for process optimization. In this work, the performance of a 100 MW system under time-invariant operation is studied. The system can achieve a roundtrip efficiency as high as 72%. The lowest levelized cost of delivered energy is obtained at 0.24 $/kWh, which is comparable to that of pumped hydro and compressed air energy storage systems.All cost data except that for the ammonia-based energy storage system are reproduced from Rastler. 8 [Color figure can be viewed at wileyonlinelibrary.com] 1 Stage number of the turbines [E-30/37,RE-5/7] Re HX 5000 Reynolds number of the main streams of all heat exchangers DV, decision variable; CP, calculated parameter; SP, specified parameter; SV, specified value.
