March 9 2020
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

Levelized decomposition cost comparison
Levelized decomposition costs (LDC) are
comparable for the three carriers 061-078
$kg-H2 at 50 tpd-H2
At high throughput LDC decreases most for
ammonia However ammonia decomposes at
a high temperature (800oC) using a catalyst
(Ni) that may require further development and
field testing
Methanol decomposition method well
established but requires steam reforming and
water gas shift catalysts Cost may decrease if
methanol reformed at gt3 atm
MCH decomposes at 2 bar using a PGM

compressor

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

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

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

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

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

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)
