Development of Liquid Hydrogen Leak Frequencies Using a Bayesian Update Process
Sep 2021
Publication
To quantify the risk of an accident in a liquid hydrogen system it is necessary to determine how often a leak may occur. To do this representative component leakage frequencies specific to liquid hydrogen can be determined as a function of the normalized leak size. Subsequently the system characteristics (e.g. system pressure) can be used to calculate accident consequences. Operating data (such as leak frequencies) for liquid hydrogen systems are very limited; rather than selecting a single leak frequency value from a literature source data from different sources can be combined using a Bayesian model. This approach provides leakage rates for different amounts of leakage distributions for leakage rates to propagate through risk assessment models to establish risk result uncertainty and a means for incorporating liquid hydrogen-specific leakage data with leakage frequencies from other fuels. Specifically other cryogenic fluids like liquefied natural gas are used as a baseline for the Bayesian analysis. This Bayesian update process is used to develop leak frequency distributions for different system component types and leak sizes. These leak frequencies can be refined as liquid hydrogen data becomes available and may then inform safety code requirements based on the likelihood of liquid hydrogen release for different systems.
Toward Design of Synergistically Active Carbon-Based Catalysts for Electrocatalytic Hydrogen Evolution
Apr 2014
Publication
Replacement of precious catalyst with cost-effective alternatives would be significantly beneficial for hydrogen production via electrocatalytic hydrogen evolution reaction (HER). All candidates thus far are exclusively metallic catalysts which suffer inherent corrosion and oxidation susceptibility during acidic proton-exchange membrane electrolysis. Herein based on theoretical predictions we designed and synthesized nitrogen (N) and phosphorus (P) dual-doped graphene as a non-metallic electrocatalyst for sustainable and efficient hydrogen production. The N and Phetero-atoms could coactivate the adjacent C atom in the graphene matrix by affecting its valence orbital energy levels to induce a synergistically enhanced reactivity toward HER. As a result the dual-doped graphene showed higher electrocatalytic HER activity than single-doped ones and comparable performance to some of the traditional metallic catalysts.
Finding Synergy Between Renewables and Coal: Flexible Power and Hydrogen Production from Advanced IGCC Plants with Integrated CO2 Capture
Feb 2021
Publication
Variable renewable energy (VRE) has seen rapid growth in recent years. However VRE deployment requires a fleet of dispatchable power plants to supply electricity during periods with limited wind and sunlight. These plants will operate at reduced utilization rates that pose serious economic challenges. To address this challenge this paper presents the techno-economic assessment of flexible power and hydrogen production from integrated gasification combined cycles (IGCC) employing the gas switching combustion (GSC) technology for CO2 capture and membrane assisted water gas shift (MAWGS) reactors for hydrogen production. Three GSC-MAWGS-IGCC plants are evaluated based on different gasification technologies: Shell High Temperature Winkler and GE. These advanced plants are compared to two benchmark IGCC plants one without and one with CO2 capture. All plants utilize state-of-the-art H-class gas turbines and hot gas clean-up for maximum efficiency. Under baseload operation the GSC plants returned CO2 avoidance costs in the range of 24.9–36.9 €/ton compared to 44.3 €/ton for the benchmark. However the major advantage of these plants is evident in the more realistic mid-load scenario. Due to the ability to keep operating and sell hydrogen to the market during times of abundant wind and sun the best GSC plants offer a 6–11%-point higher annual rate of return than the benchmark plant with CO2 capture. This large economic advantage shows that the flexible GSC plants are a promising option for balancing VRE provided a market for the generated clean hydrogen exists.
On the Climate Impacts of Blue Hydrogen Production
Nov 2021
Publication
Natural gas based hydrogen production with carbon capture and storage is referred to as blue hydrogen. If substantial amounts of CO2 from natural gas reforming are captured and permanently stored such hydrogen could be a low-carbon energy carrier. However recent research raises questions about the effective climate impacts of blue hydrogen from a life cycle perspective. Our analysis sheds light on the relevant issues and provides a balanced perspective on the impacts on climate change associated with blue hydrogen. We show that such impacts may indeed vary over large ranges and depend on only a few key parameters: the methane emission rate of the natural gas supply chain the CO2 removal rate at the hydrogen production plant and the global warming metric applied. State-of-the-art reforming with high CO2 capture rates combined with natural gas supply featuring low methane emissions does indeed allow for substantial reduction of greenhouse gas emissions compared to both conventional natural gas reforming and direct combustion of natural gas. Under such conditions blue hydrogen is compatible with low-carbon economies and exhibits climate change impacts at the upper end of the range of those caused by hydrogen production from renewable-based electricity. However neither current blue nor green hydrogen production pathways render fully “net-zero” hydrogen without additional CO2 removal.
The Hydrogen Economy and Jobs of the Future
Nov 2018
Publication
Growth in the hydrogen and fuel cell industries will lead to vast new employment opportunities and these will be created in a wide variety of industries skills tasks and earnings. Many of these jobs do not currently exist and do not have occupational titles defined in official classifications. In addition many of these jobs require different skills and education than current jobs and training requirements must be assessed so that this rapidly growing part of the economy has a sufficient supply of trained and qualified workers. We discuss the current hydrogen economy and technologies. We then identify by occupational titles the new jobs that will be created in the expanding hydrogen/fuel cell economy estimate the average US salary for each job identify the minimum educational attainment required to gain entry into that occupation and specify the recommended university degree for the advanced educational requirements. We provide recommendations for further research.

The Role of Hydrogen in Achieving Long Term Japanese Energy System Goals
Sep 2020
Publication
This research qualitatively reviews literature regarding energy system modeling in Japan specific to the future hydrogen economy leveraging quantitative model outcomes to establish the potential future deployment of hydrogen in Japan. The analysis focuses on the four key sectors of storage supplementing the gas grid power generation and transportation detailing the potential range of hydrogen technologies which are expected to penetrate Japanese energy markets up to 2050 and beyond. Alongside key model outcomes the appropriate policy settings governance and market mechanisms are described which underpin the potential hydrogen economy future for Japan. We find that transportation gas grid supplementation and storage end-uses may emerge in significant quantities due to policies which encourage ambitious implementation targets investment in technologies and research and development and the emergence of a future carbon pricing regime. On the other hand for Japan which will initially be dependent on imported hydrogen the cost of imports appears critical to the emergence of broad hydrogen usage particularly in the power generation sector. Further the consideration of demographics in Japan recognizing the aging shrinking population and peoples’ energy use preferences will likely be instrumental in realizing a smooth transition toward a hydrogen economy.

Life Cycle Assessment of Hydrogen Transportation Pathways via Pipelines and Truck Trailers: Implications as a Low Carbon Fuel
Sep 2022
Publication
Hydrogen fuel cells have the potential to play a significant role in the decarbonization of the transportation sector globally and especially in California given the strong regulatory and policy focus. Nevertheless numerous questions arise regarding the environmental impact of the hydrogen supply chain. Hydrogen is usually delivered on trucks in gaseous form but can also be transported via pipelines as gas or via trucks in liquid form. This study is a comparative attributional life cycle analysis of three hydrogen production methods alongside truck and pipeline transportation in gaseous form. Impacts assessed include global warming potential (GWP) nitrogen oxide volatile organic compounds and particulate matter 2.5 (PM2.5). In terms of GWP the truck transportation pathway is more energy and ecologically intensive than pipeline transportation despite gaseous truck transport being more economical. A sensitivity analysis of pipeline transportation and life cycle inventories (LCI) attribution is included. Results are compared across multiple scenarios of the production and transportation pathways to discover the strongest candidates for minimizing the environmental footprint of hydrogen production and transportation. The results indicate the less ecologically intensive pathway is solar electrolysis through pipelines. For 1 percent pipeline attribution the total CO2eq produced per consuming 1 MJ of hydrogen in a fuel cell pickup truck along this pathway is 50.29 g.

1921–2021: A Century of Renewable Ammonia Synthesis
Apr 2022
Publication
Synthetic ammonia manufactured by the Haber–Bosch process and its variants is the key to securing global food security. Hydrogen is the most important feedstock for all synthetic ammonia processes. Renewable ammonia production relies on hydrogen generated by water electrolysis using electricity generated from hydropower. This was used commercially as early as 1921. In the present work we discuss how renewable ammonia production subsequently emerged in those countries endowed with abundant hydropower and in particular in regions with limited or no oil gas and coal deposits. Thus renewable ammonia played an important role in national food security for countries without fossil fuel resources until after the mid-20th century. For economic reasons renewable ammonia production declined from the 1960s onward in favor of fossil-based ammonia production. However renewable ammonia has recently gained traction again as an energy vector. It is an important component of the rapidly emerging hydrogen economy. Renewable ammonia will probably play a significant role in maintaining national and global energy and food security during the 21st century.

Hydrogen Production in the Swedish Power Sector: Considering Operational Volatilities and Long-term Uncertainties
Nov 2020
Publication
With more renewables on the Swedish electricity market while decommissioning nuclear power plants electricity supply increasingly fluctuates and electricity prices are more volatile. There is hence a need for securing the electricity supply before energy storage solutions become widespread. Electricity price fluctuations moreover affect operating income of nuclear power plants due to their inherent operational inflexibility. Since the anticipated new applications of hydrogen in fuel cell vehicles and steel production producing hydrogen has become a potential source of income particularly when there is a surplus supply of electricity at low prices. The feasibility of investing in hydrogen production was investigated in a nuclear power plant applying Swedish energy policy as background. The analysis applies a system dynamics approach incorporating the stochastic feature of electricity supply and prices. The study revealed that hydrogen production brings alternative opportunities for large-scale electricity production facilities in Sweden. Factors such as hydrogen price will be influential and require in-depth investigation. This study provides guidelines for power sector policymakers and managers who plan to engage in hydrogen production for industrial applications. Although this study was focused upon nuclear power sources it can be extended to hydrogen production from renewable energy sources such as wind and solar.

Current Status of Automotive Fuel Cells for Sustainable Transport
May 2019
Publication
Automotive proton-exchange membrane fuel cells (PEMFCs) have finally reached a state of technological readiness where several major automotive companies are commercially leasing and selling fuel cell electric vehicles including Toyota Honda and Hyundai. These now claim vehicle speed and acceleration refueling time driving range and durability that rival conventional internal combustion engines and in most cases outperform battery electric vehicles. The residual challenges and areas of improvement which remain for PEMFCs are performance at high current density durability and cost. These are expected to be resolved over the coming decade while hydrogen infrastructure needs to become widely available. Here we briefly discuss the status of automotive PEMFCs misconceptions about the barriers that platinum usage creates and the remaining hurdles for the technology to become broadly accepted and implemented.
