Convertible bonds for hydrogen energy storage

What motivates reversible hydrogen storage materials?

For example, compensating for intermittent renewable energy generation is an often-cited motivation for developing reversible hydrogen storage materials, but research has typically focused on cross-cutting needs rather than specific use cases (for example, robust catalysts to enable reversible hydrogen release from LOHCs).

How is hydrogen stored?

In the former case, the hydrogen is stored by altering its physical state, namely increasing the pressure (compressed gaseous hydrogen storage, CGH 2) or decreasing the temperature below its evaporation temperature (liquid hydrogen storage, LH 2) or using both methods (cryo-compressed hydrogen storage, CcH 2).

What is hydrogen energy storage?

Hydrogen is a versatile energy storage medium with significant potential for integration into the modernized grid. Advanced materials for hydrogen energy storage technologies including adsorbents, metal hydrides, and chemical carriers play a key role in bringing hydrogen to its full potential.

What are hydrogen-based strategies for high-density energy storage?

Hydrogen-based strategies for high-density energy storage 127, 128, 129 include compressed gas, cryogenic liquid (black circles) 130, hydrogen chemically bound as a hydride 63, 131, 132, 133, 134, 135, 136 (purple triangles) or as an LOHC 32 (orange squares) or hydrogen physisorbed within a porous adsorbent 24 (light-blue pentagons).

Are hydrogen carrier polymers inspired by reversible charge storage with bistable redox-active polymers?

Here, we focus on the design principles of hydrogen carrier polymers inspired by reversible charge storage with bistable redox-active polymers. The search for hydrogen carrier polymers has been focused on changes in the properties of redox polymers during charging.

Is hydrogen energy storage a viable alternative?

The paper offers a comprehensive analysis of the current state of hydrogen energy storage, its challenges, and the potential solutions to address these challenges. As the world increasingly seeks sustainable and low-carbon energy sources, hydrogen has emerged as a promising alternative.
