How can a hydrogen economy be implemented?

The successful implementation of a hydrogen economy requires advancements in hydrogen production, transportation (and/or distribution), utilization, and storage technologies, as well as the establishment of supportive policies and infrastructure to enable widespread adoption . Table 1.

Why do we need more energy to produce hydrogen?

Energy required for production: there are also significant losses in efficiency during the storage and transportation of hydrogen.

Are hydrogen storage technologies sustainable?

The outcomes showed that with the advancements in hydrogen storage technologies and their sustainability implications, policymakers, researchers, and industry stakeholders can make informed decisions to accelerate the transition towards a hydrogen-based energy future that is clean, sustainable, and resilient.

Can hydrogen be stored as a fuel?

This makes it more difficult and expensive to store and transport hydrogen for use as a fuel (Rivard et al. 2019). There are several storage methods that can be used to address this challenge, such as compressed gas storage, liquid hydrogen storage, and solid-state storage.

What are the benefits of hydrogen storage?

4. Distribution and storage flexibility: hydrogen can be stored and transported in a variety of forms, including compressed gas, liquid, and solid form . This allows for greater flexibility in the distribution and storage of energy, which can enhance energy security by reducing the vulnerability of the energy system to disruptions.

Will a hydrogen-based energy transition happen overnight?

A hydrogen-based energy transition will not happen overnight. Hydrogen will likely trail other strategies such as electrification of end-use sectors, and its use will target specific applications. The need for a dedicated new supply infrastructure may limit hydrogen use to certain countries that decide to follow this strategy.
