Hydrogen becomes an energy storage carrier

Is hydrogen an energy carrier?

The study presents a comprehensive review on the utilization of hydrogen as an energy carrier, examining its properties, storage methods, associated challenges, and potential future implications. Hydrogen, due to its high energy content and clean combustion, has emerged as a promising alternative to fossil fuels in the quest for sustainable energy.

What is hydrogen storage?

Hydrogen storage plays a pivotal role in harnessing and transporting hydrogen as an energy carrier. Diverse techniques have been devised to securely and effectively store hydrogen. Below is an overview of contemporary hydrogen storage methods, as depicted in Figure 19. The main hydrogen storage methods.

Why is hydrogen a promising energy carrier or fuel?

Outstanding properties and features of hydrogen make it a very promising energy carrier or fuel, although it is not naturally available as a ready to use substance. Different methods are being used in order to mass produce hydrogen.

Why is hydrogen a transport fuel?

Hydrogen contains more energy per unit of mass than natural gas or gasoline, making it attractive as a transport fuel (Table 1). However, hydrogen is the lightest element and so has a low energy density per unit of volume. This means that larger volumes of hydrogen must be moved to meet identical energy demands as compared with other fuels.

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 challenges in adopting hydrogen as an energy carrier?

The challenges in adopting hydrogen as an energy carrier, such as production costs, safety concerns, and infrastructure requirements are also explored. The future implications of hydrogen are promising but dependent on technological advancements and policy interventions.
