What are hydrogen carriers

bull Programrsquos definition

ndash Hydrogen carriers are hydrogen-rich liquid or solid phase materials from which hydrogen can be liberated on-demand Ideal hydrogen carriers have relatively high hydrogen densities at low pressure and near ambient temperature

bull Consensus from November workshop on hydrogen carriers

ndash Keep a broad definition of hydrogen carriers and let the requirements for specific applications narrow the scope of hydrogen carriers for consideration for those applications

2 US DEPARTMENT OF ENERGY OFFICE OF ENERGY EFFICIENCY amp RENEWABLE ENERGY FUEL CELL TECHNOLOGIES OFFICE

Examples of program activities on hydrogen carriers to date

bull Prior to 2010 ndash supported Air Products and Chemicals to investigate heterocyclic materials as potential hydrogen storage materials focused efforts on n-ethylcarbazole

bull 2018 ndash Initiated techno-economic analysis at Argonne National Lab to establish a baseline comparison between conventional compressed and liquid hydrogen delivery with several commonly cited hydrogen carriers

bull 2018 ndash Initiated preliminary efforts within HyMARC to investigate hydrogen carrier materials with an emphasis on ldquoadditionalrdquo potential benefits (eg chemical compression)

bull 2019 ndash included a topic in the FCTO FOA on hydrogen carriers selected 4 projects to investigate and develop novel hydrogen carrier concepts

bull Nov 2019 ndash Held a hydrogen carrier workshop in Golden CO - 74 participants representing industry universities and national labs and from N America Europe and Asia

Factors to consider for hydrogen carriers

1 Capacity of carrier productiondehydrogenation plants

a Production - assumed plants not built and sized just based on targeted H2 delivery per day

b Dehydrogenation - plants are sized for targeted hydrogen capacity

2 Production - cost and energy to produce hydrogenated carrier

3 Transmission ndash cost to delivery carrier from point of production to storage terminal (rail ship pipeline etc) and then to city gate (150 km by truck)

a For two-way carriers - includes cost to return dehydrogenated product to hydrogenation site

4 Dehydrogenation - cost and energy to dehydrogenate and release the hydrogen from the carrier at the city gate terminal

a Includes purification costs to clean-up the hydrogen

b For two-way carriers ndash includes replacement costs of lost carrier (eg evaporation side reactions etc)

Production Transmission Dehydrogenation Distribution 8 US DEPARTMENT OF ENERGY OFFICE OF ENERGY EFFICIENCY amp RENEWABLE ENERGY FUEL CELL TECHNOLOGIES OFFICE

Plant capacity matters

Example ndash methanol ndash production method can change as plant capacity varies to reduce capital costs

9 US DEPARTMENT OF ENERGY OFFICE OF ENERGY EFFICIENCY amp RENEWABLE ENERGY FUEL CELL TECHNOLOGIES OFFICE

Levelized cost for production

bull Levelized production cost for methanol the lowest when produced in high capacity plants (10k tonday)

bull Methylcyclohexane production through hydrogenation of toluene competitive with methanol levelized production cost

bull Ammonia production highest on a levelized production cost plants more capital intensive than methanol plants

Transmission cost comparison through various means

bull H2 capacity of the carrier is an important factor in determining the transmission cost by rail - Toluene has nearly the same train transmission cost as methanol on tpd basis but is gt3X costlier on kg-H2

basis

bull Toxicity and handling are also important factors in determining rail transmission costs - Ammonia has nearly the same H2 capacity as methanol but is gt2X costlier to move by train

bull Long H2 or carrier pipelines (gt1000 mile) do not offer significant cost savings - Pipelines may not be economically viable for two-way carriers

Comparison costs by rail by pipeline by ship for MCHtoluene

Factors to consider for hydrogen carriers

1 Capacity of carrier productiondehydrogenation plants

a Production - assumed plants not built and sized just based on targeted H2 delivery per day

b Dehydrogenation - plants are sized for targeted hydrogen capacity

2 Production - cost and energy to produce hydrogenated carrier

3 Transmission ndash cost to delivery carrier from point of production to storage terminal (rail ship pipeline etc) and then to city gate (150 km by truck)

a For two-way carriers - includes cost to return dehydrogenated product to hydrogenation site

4 Dehydrogenation - cost and energy to dehydrogenate and release the hydrogen from the carrier at the city gate terminal

a Includes purification costs to clean-up the hydrogen

b For two-way carriers ndash includes replacement costs of lost carrier (eg evaporation side reactions etc)

Transmission cost comparison through various means

bull H2 capacity of the carrier is an important factor in determining the transmission cost by rail - Toluene has nearly the same train transmission cost as methanol on tpd basis but is gt3X costlier on kg-H2

basis

bull Toxicity and handling are also important factors in determining rail transmission costs - Ammonia has nearly the same H2 capacity as methanol but is gt2X costlier to move by train

bull Long H2 or carrier pipelines (gt1000 mile) do not offer significant cost savings - Pipelines may not be economically viable for two-way carriers

Factors to consider for hydrogen carriers

1 Capacity of carrier productiondehydrogenation plants

a Production - assumed plants not built and sized just based on targeted H2 delivery per day

b Dehydrogenation - plants are sized for targeted hydrogen capacity

2 Production - cost and energy to produce hydrogenated carrier

3 Transmission ndash cost to delivery carrier from point of production to storage terminal (rail ship pipeline etc) and then to city gate (150 km by truck)

a For two-way carriers - includes cost to return dehydrogenated product to hydrogenation site

4 Dehydrogenation - cost and energy to dehydrogenate and release the hydrogen from the carrier at the city gate terminal

a Includes purification costs to clean-up the hydrogen

b For two-way carriers ndash includes replacement costs of lost carrier (eg evaporation side reactions etc)

Transmission cost comparison through various means

bull H2 capacity of the carrier is an important factor in determining the transmission cost by rail - Toluene has nearly the same train transmission cost as methanol on tpd basis but is gt3X costlier on kg-H2

basis

bull Toxicity and handling are also important factors in determining rail transmission costs - Ammonia has nearly the same H2 capacity as methanol but is gt2X costlier to move by train

bull Long H2 or carrier pipelines (gt1000 mile) do not offer significant cost savings - Pipelines may not be economically viable for two-way carriers

Page 12: Preliminary Techno-Economic Analysis of Hydrogen Carriers

Transmission cost comparison through various means

bull H2 capacity of the carrier is an important factor in determining the transmission cost by rail - Toluene has nearly the same train transmission cost as methanol on tpd basis but is gt3X costlier on kg-H2

basis

bull Toxicity and handling are also important factors in determining rail transmission costs - Ammonia has nearly the same H2 capacity as methanol but is gt2X costlier to move by train

bull Long H2 or carrier pipelines (gt1000 mile) do not offer significant cost savings - Pipelines may not be economically viable for two-way carriers

Comparison costs by rail by pipeline by ship for MCHtoluene

Volumetric capacity

Preliminary TEA suggests water removal is the most expensive process

TEA analysis suggests efforts are needed to perform regeneration at higher concentrations or a use case with cheap source of heat eg nuclear reactor

Deliverable capacity limited by the solubility of formate at 20 degC Usable capacity limited by the solubility of bicarbonate at 60 degC

Summary

bull Hydrogen carriers can be cost competitive with gaseous hydrogen production

ndash Production capacity can influence cost competitiveness

ndash Transmission costs can vary depending on nature of the hydrogen carrier

ndash Two-way carriers are disadvantaged by two-way transportation costs and replacement costs

bull Application specific requirements need to be considered when determining suitability of a hydrogen carrier

bull Boundary conditions should be considered when comparing different TEAs

bull Future activities

ndash Including comparison with liquid hydrogen transmission and distribution

ndash Expand analysis of other types of hydrogen carriers (eg formate salts)

ndash Investigation of impact of yield cycle life energy use etc

ndash Consider other potential benefits (eg chemical compression)
