Hydrogen is touted as the ultimate clean energy fuel and no one disputes its qualities. However, many challenges remain, including the safe storage and transportation of hydrogen fuel.
Despite numerous safety studies by universities, governments and automakers like Toyota still have a bad reputation for hydrogen. People want a storage solution that isn’t a high-pressure tank.
Deakin University might have that a solution: Its researchers have discovered an energy-efficient way to trap hydrogen gas in a boron nitride powder. The powder has a large surface area in relation to its volume, making it an ideal catching material.
Once the gas has been absorbed by the powder, it can be transported at normal atmospheric pressure, which is considered safer than a high-pressure tank or liquid hydrogen. The researchers point out that their technique is also less energy-intensive and more secure than the other storage alternatives.
When used as a fuel, the hydrogen can be released by heating the stream, which can later be reused for the same purpose. It remains to be seen whether this technique will scale to an industrial scale and how practical it would be in real-world applications, but it’s an intriguing breakthrough.
Of course, there’s also the question of how hydrogen is even produced, and hopefully from clean sources like this experimental alloy or plants.
