One of the major challenges at all stages is the energy efficiency of the devices involved. However, significant design challenges at each stage still exist – from its production to storage and transportation, to its end use. With a significant investment in a hydrogen ecosystem, technical challenges related to hydrogen are back in focus. The first Energy Earthshot, called Hydrogen Shot, targets lowering the cost of green hydrogen to $1/kg by the end of the decade. Department of Energy (DOE) just launched the Energy Earthshots Initiative in June for an accelerated energy transition. The biggest investment, globally, has come from the European Union, which accounts for more than half of hydrogen-based project investments in the early part of this decade. Investment in green hydrogen now exceeds $1 billion USD per year. The high cost is linked to the infrastructure investment and demand, which is now getting a boost because of regulations and proactive actions being taken by governments around the world. The cost of green hydrogen production (hydrogen produced using renewable energy) is around $5 USD per kilogram, which has made it less competitive compared to carbon-heavy fuels such as natural gas or kerosene. Three major challenges with hydrogen democratization are cost, infrastructure and scale. renewables or nuclear).” Three Key Challenges in Hydrogen Democratization Across Industries steelmaking or aviation) indirect electrification is possible via hydrogen produced by water electrolysis with low carbon power (e.g. “In the so-called hard-to-abate sectors (e.g. transportation or industry), benefiting from the strong decrease of renewable power costs, are key components of the roadmap for reaching the 1.5 C target by 2050,” says Claude Heller, former Director of Group R&D Programs for Air Liquide who is now a Senior Advisor for the Hydrogen Economy.

“The decrease of the carbon content of power and the electrification of many economic activities (e.g. Similar observations can be made for other sectors where hydrogen-based solutions must play a critical role alongside other important technologies – such as energy efficiency, batteries and carbon capture – to achieve the net-zero goal. It's important to note that electrification will continue to help reduce emissions, especially with short-haul flights, but more than 90% of emissions in the aviation sector are produced by mid- to long-range flights, according to the Air Transport Action Group. One proposed roadmap for net-zero carbon proposed for the aviation industry (see figure 1) shows that only a sustainable fuel, such as hydrogen, provides a realistic path to net zero by 2050. Let’s look at the aviation industry as an example. If we look at any of the industrial sectors in detail, we can see the potential impact of hydrogen to reduce greenhouse gas emissions. It provides many pathways toward sustainability – from energy storage to cleaner energy production and propulsion – while complementing other solutions, such as batteries. There are synergies among major industries like aerospace, energy and automotive to establish a sustainable infrastructure network for hydrogen. Hydrogen is a significant part of the solution for carbon neutrality.

Efficient implementations of the FDTD method in a high level language are also provided.Synergy Across Industries Point to Hydrogen Adoption Post processing methods such as network parameter extraction and far-field transformations are also detailed. It also provides step by step guides to modeling physical sources, lumped-circuit components, absorbing boundary conditions, perfectly matched layer absorbers, and sub-cell structures. Introduction to the Finite-Difference Time-Domain (FDTD) Method for Electromagnetics guides the reader through the foundational theory of the FDTD method starting with the one-dimensional transmission-line problem and then progressing to the solution of Maxwell's equations in three dimensions. The book provides all the background required to either research or apply the FDTD method for the solution of Maxwell's equations to practical problems in engineering and science. It can accompany an undergraduate or entry-level graduate course or be used for self-study.
