Company Claims Room-Temp, Low-Pressure Hydrogen Storage
A company called H2MOF says it has found a way to store solid-state hydrogen at ambient temperatures and relatively low pressure. The tech is poised to undergo industrial-scale testing which, if proven successful, could address major challenges surrounding hydrogen storage and transportation.
Hydrogen is the smallest atom, but it packs an energetic punch. Many scientists have been keen to tap into this energy source as a potentially greener alternative to fossil fuels. But finding cost-effective and energy-efficient ways of storing it is one of several major hurdles that must be overcome before hydrogen can be more broadly adopted as an energy source.
The two main hydrogen storage options currently on the market involve compressing it under pressures between 350 and 700 bar (approximately 350 to 750 times greater than atmospheric pressure) and liquifying it by cooling it down to –253° C.
“Both processes are extremely energy intensive and generate energy losses equivalent to 15 to 40 percent of the hydrogen energy stored,” explains Samer Taha, co-founder and CEO of H2MOF. Both techniques also require expensive equipment and infrastructure on the hydrogen producer’s side, and in many cases on the hydrogen receiver’s side as well, he says.
These challenges prompted scientists at H2MOF to develop a novel material that binds with hydrogen. Leading the research are H2MOF co-founders Sir Fraser Stoddart, who won the 2016 Nobel Prize in Chemistry for his work on developing molecular machines, and Omar M. Yaghi, a professor of chemistry at University of California, Berkeley. (…)
