6 FAQs about [Problems with hydrogen energy storage]

What are the challenges associated with hydrogen storage?

There are several challenges associated with hydrogen storage such as low efficiency, long refueling times, and short life span of the materials used. To be suitable for transportation, it is necessary to make hydrogen denser in terms of energy. Storage is the fundamental technological issue for a successful hydrogen economy.

What are the challenges facing hydrogen energy?

One of the primary challenges facing hydrogen energy is achieving cost competitiveness with traditional energy sources. While hydrogen production costs have declined in recent years, particularly for renewable hydrogen produced via electrolysis, they remain higher than those of fossil fuels such as natural gas.

Is thermodynamics a hydrogen storage challenge?

As will be evident below, however, thermodynamics is only one of several hydrogen storage challenges.

Why is hydrogen storage so hard?

“Hydrogen storage is actually really hard because of the chemical composition of hydrogen, it has very low energy density, so compared to natural gas for example, it’s actually quite hard to store. It’s a small molecule, which makes it hard to contain as well, it’s not easy. Additionally, it’s got a very low freezing point.”

Why do we need a hydrogen storage system?

Hydrogen production, storage, and utilization processes must be optimized to maximize efficiency and performance. Electrolysis systems, fuel cells, and hydrogen storage technologies face challenges related to energy conversion efficiency, system reliability, and durability.

Why are high strength steels avoided in hydrogen storage systems?

High strength steels are avoided in hydrogen storage systems due to embrittlement. Assessing material's susceptibility to hydrogen permeation and trapping is crucial. Trace amounts of hydrogen penetrating the steel accumulates at the crack tips. Exposure time, material's microstructure and residual stresses are critical.
