The goal of this capstone is to provide insight onto what pathways may be most economically efficient in establishing hydrogen infrastructure and determine what options could be applied for remote locations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Introduction<\/h2>\n\n\n\n<p>Hydrogen fuel is one of the fuels considered for replacing oil and gas in vehicles.&nbsp; There are many properties of it which are appealing: it has a high energy content, emits zero carbon at point of use, can be used for combustion or in fuel cells.&nbsp; However, since it is an energy carrier an energy source like solar energy, biomass or hydrocarbons must be used to produce it.&nbsp; Depending on the method for producing energy, the hydrogen fuel can be produced with very low greenhouse gas emissions.<\/p>\n\n\n\n<p>However it also faces many challenges as well.&nbsp; Hydrogen requires energy in order to be produced, and currently most hydrogen is produced by steam methane reformers, which produces greenhouse gas emissions.&nbsp; Transporting the hydrogen fuel is costly&nbsp; due to how the very low density of hydrogen gas, this makes it costly to store as it must be pressurized or liquefied prior to use.&nbsp; Along with that, there are always potential hazards with hydrogen\u2019s high flammability, requiring extra precautions while transporting, storing, and using.&nbsp; Very high hydrogen purity is required for use in Fuel cell electric vehicles, requiring expensive purification or production processes to be used.&nbsp; Currently the majority of hydrogen is produced for industrial applications such as making ammonia for fertilizers or used in oil and gas operations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Objectives<\/h2>\n\n\n\n<p>Hydrogen fuel may be a potential energy source where electrification, biofuels, carbon capture and storage are unable to efficiently replace fossil fuels. One such industry is for the shipping of goods, where weight, cargo volume, and down time are factors that can greatly affect the economics of shipping industries. The objective of this capstone project is to determine the possible hydrogen delivery pathways for fuel cell electric vehicles utilized for long haul road transport.&nbsp;<br><br>A comparison of the following hydrogen delivery pathways will be conducted:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Distribution of hydrogen by hydrogen tube trailers<\/li><li>Distribution of hydrogen by hydrogen pipeline<\/li><li>Onsite hydrogen production via electrolysis at fuel station<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Methodology<\/h2>\n\n\n\n<p>A levelized cost of hydrogen will be conducted using the following formula: <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"743\" height=\"171\" src=\"https:\/\/blogs.ubc.ca\/melceencapstoneprojects\/files\/2021\/04\/LCOH-formula.png\" alt=\"\" class=\"wp-image-880\" srcset=\"https:\/\/blogs.ubc.ca\/melceencapstoneprojects\/files\/2021\/04\/LCOH-formula.png 743w, https:\/\/blogs.ubc.ca\/melceencapstoneprojects\/files\/2021\/04\/LCOH-formula-300x69.png 300w\" sizes=\"auto, (max-width: 743px) 100vw, 743px\" \/><\/figure>\n\n\n\n<p>The useful life will be dependent on the hydrogen delivery pathway analysed while a discount rate of 15% is assumed for this study.

The figure shows that for long distance hydrogen distribution, the cost of using hydrogen tube trailers, hydrogen pipelines are approximately the same.

The cost of energy and the fuel station are large components for tube trailers, while the hydrogen pipeline is dominated by the capital expenditures from pipeline. The high pressure pipeline has reduced costs for the fuel station due to not requiring hydrogen compression or storage but the cost of energy to achieve the high pipeline pressure makes the LCOH roughly the same. The onsite electrolysis is largely dominated by the cost of electricity used for production suggesting that with cheaper sources of electricity the LCOH could be lowered.<\/p>\n\n\n\n<h2 class=\"has-medium-font-size wp-block-heading\">Sensitivity Analysis<\/h2>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/blogs.ubc.ca\/melceencapstoneprojects\/files\/2021\/04\/sensi-1.png\" alt=\"\" class=\"wp-image-877\" width=\"786\" srcset=\"https:\/\/blogs.ubc.ca\/melceencapstoneprojects\/files\/2021\/04\/sensi-1.png 723w, https:\/\/blogs.ubc.ca\/melceencapstoneprojects\/files\/2021\/04\/sensi-1-300x175.png 300w\" sizes=\"(max-width: 723px) 100vw, 723px\" \/><figcaption>Figure 3 &#8211; Sensitivity analysis of optimistic and pessimistic scenarios<\/figcaption><\/figure><\/div>\n\n\n\n<p>In the Sensitivity analysis the cost of hydrogen production, hydrogen storage, and hydrogen demand were adjusted to see the impact on the LCOH in this scenario. The cost of hydrogen production and storage were decreased while hydrogen demand was increased in the optimistic scenario while the opposite was done for the pessimistic scenario.<\/p>\n\n\n\n<h2 class=\"has-medium-font-size wp-block-heading\">Policy Options<\/h2>\n\n\n\n<p>Some policy options have been looked at in literature and have examined the effects of the following policy options:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Carbon tax<\/li><li>Cap and Trade<\/li><li>Capital Subsidies<\/li><li>Low carbon fuel standards<\/li><\/ul>\n\n\n\n<p>For energy policy options that could help to lower the LCOH, some research has been done on financial incentives and market based policies.&nbsp; Research has found that production subsidies and electricity incentives were the most effective policies to facilitate low-carbon hydrogen production.&nbsp; Capital subsidies were found to often promote hydrogen production with Steam methane reformer and did not scale well with high demand scenarios.&nbsp; This policy findings matches the study here where the energy used for transportation or hydrogen production are large components of the LCOH.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>We can conclude from this capstone that onsite hydrogen production with electrolysis has the lowest levelized cost of hydrogen out of the pathways examined.  This leads us to conclude that using hydrogen delivery methods may not be the most economically efficient pathway for hydrogen distribution.  The large distance required to be covered with a regular supply of hydrogen makes it very costly in terms of energy and capital expenditures required.  It was generally seen that the cost of hydrogen production affected the LCOH the most in the sensitivity analysis.  The onsite electrolysis could be a viable option for hydrogen production in remote areas as it has the advantage of not being as it can use off the grid energy resources and are able to provide Hydrogen fuel at a lower levelized cost than the delivered pathways.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Acknowledgements<\/h2>\n\n\n\n<p><img decoding=\"async\" class=\"wp-image-859\" style=\"width: 150px;\" src=\"https:\/\/blogs.ubc.ca\/melceencapstoneprojects\/files\/2021\/04\/1613969935393.jpg\" alt=\"\"> Mentor: Barbar Moawad, Navius Research Inc.<br>I would like to express my gratitude to my capstone mentor, Barbar Moawad for his mentorship, support and patience throughout this capstone project this term.<\/p>\n\n\n\n<p><img decoding=\"async\" class=\"wp-image-860\" style=\"width: 150px;\" src=\"https:\/\/blogs.ubc.ca\/melceencapstoneprojects\/files\/2021\/04\/Vladan-Prodanovic.png\" alt=\"\"> Course instructor: Dr. Vladan Prodanovic, MEL CEEN Program Director<\/p>\n\n\n\n<p>I&#8217;d like to thank Dr. Vladan for organizing the course this term for part-time CEEN students and for providing me the opportunity to work with Navius Research<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">References<\/h2>\n\n\n\n<p>Antony, A., Maheshwari, N.
