Although hydrogen is typically transported in liquid or gaseous form, the handling and operating constraints of pure hydrogen put a heavy strain on the storage containers. Hydrogen carriers are hydrides or compounds of hydrogen, forming through the chemical reaction of a metal or a chemical with hydrogen. Typically, this is easy to transport over long distances. Storing these carriers is also convenient and, with additional research and development (R&D) into hydrogen carriers, startups look to increase the purity and efficiency of the separation process to produce the hydrogen. Metal hydrides, like magnesium hydride, further possess the capacity to chemically store hydrogen in their metallic lattice. LOHC, chemical hydrides, and nanostructures are also under investigation and development for transporting hydrogen.

Flux Technology produces Metal-Organic Frameworks (MOF) for Hydrogen Storage

US-based nanotechnology startup Flux Technology develops MOF nanocomposites for hydrogen storage and transportation. MOFs usually consist of a regular array of positively charged metal ions surrounded by organic linker molecules.

6. Carbon Capture, Utilization & Storage (CCUS)

The current global production of hydrogen primarily uses fossil fuels, making it unsustainable. Popular methods like steam methane reforming and coal gasification contributes to greenhouse gas emissions, and until alternatives become cost- and power-effective, these will continue to be the main sources of hydrogen production. Incorporating CCUS, or blue hydrogen technologies drastically reduce the environmental impact of conventional production methods and increases the sustainability of the processes. These technologies are incorporated into large-scale hydrogen production venues to decrease carbon emissions or convert them into usable feedstock for other processes. For example, CCUS enables the production of fertilizers and is useful in enhanced oil recovery (EOR). Moreover, forming solid carbon by-products is an effective method of reusing the wastes of hydrogen production. Furthermore, redirecting gaseous carbon emissions for use in other industrial processes ensures zero waste and emission loops.

7. Hydrogen Distribution

A major hurdle for building the hydrogen economy is the transportation and distribution of the fuel. Depending on the site of production and usage, different methods of distribution are under consideration. The regional distribution of hydrogen through new pipelines or retrofitting current natural gas pipelines is gaining traction. Trains and ships also transport hydrogen, in either liquid or gaseous form, across regions. Tube trailers and liquid tankers are viable solutions for distributing hydrogen through highways. The handling of the hydrogen storage containers is important because of the flammability and material-embrittling nature of hydrogen. Hydrogen refueling stations also enable hydrogen highways and mitigate refueling challenges of hydrogen fuel cell vehicles, especially in trucks and buses.

The refueling network includes centralized generation units with distributed refueling, distributed generation, and third-party generation with offtake. The startup factors in distance from hydrogen supply sites and frequency of aggregation of fleets when choosing refueling sites.

8. Hydrogen Liquefaction & Compression

The need to develop containers that store hydrogen is crucial for scaling the hydrogen economy. The most usable form of storing liquid hydrogen is in cryogenic tanks, also known as dewars. These containers handle liquid hydrogen at a temperature of -253 C, without leakages, while sustaining purity. There are various types of dewars ranging from Type I to Type IV, depending on the materials in the walls and their carrying capacity. In addition, compressed gas storage tanks are useful to store high-pressure hydrogen gas. Hydrogen gas is relatively easier to handle in comparison to liquified hydrogen because of the temperature constraints of liquid hydrogen. However, it is not ready to use in industrial applications. Cryo-compressed hydrogen involves high-pressure storage of hydrogen to decrease boil-off upon exposure to the atmosphere, making it cost-effective and easy to handle.
