Hydrogen could be the future of energy - but there's one big road block

Read entire articleThe hydrogen embrittlement challenge is a highly complex materials and engineering problem. There are many aspects that still need to be understood before tangible solutions can be proposed.
For example, what are the conditions for hydrogen entry into different metals? Can this be controlled? Is it possible to completely stop hydrogen entry in metals using coatings or other surface treatments? What if these coatings get a scratch? If the hydrogen does get in, under what conditions will it cause failure of the metal? How much hydrogen is too much? How quickly will it accumulate? Can we design new engineering alloys that can better resist hydrogen embrittlement for the global hydrogen economy? If so, will the new alloys be economically feasible?
These questions can only be answered through collaboration between researchers and engineers who have a deep understanding of hydrogen embrittlement.
