How might storing electricity in the form of solid hydrogen change the future landscape of energy? We believe it could change the performance of mobile power, lower the cost of renewable energy production, and change the nature of refueling your car by ‘swapping out’ boxes of fuel.
Hydrogen & Electricity = ‘Hydricity’
Electricity powers the future. Look beyond the transportation sector of liquid fuels, and most devices and machines run on electrons. Today, we understand the important role of electricity in our world, and tomorrow we might understand its sister companion – hydrogen.
Hydrogen might be the most misunderstood and misrepresented piece of the future energy landscape. Devotees often overstate it as the savior of Planet Earth, and staunch critics underestimate its short term challenges for longer term potential in energy systems and materials science.
A ‘Hydrogen economy’ is an economy driven by electricity. The hydrogen is merely a way of storing electron power via chemical bonds of hydrogen. So hydrogen and electricity are one in the same thing. Ballard Power Founder Geoffrey Ballad has coined the phrase ‘hydricity’ to help people understand the balance of these electrons carriers.
Fuel cells capture energy released when coated membranes strip apart those hydrogen-hydrogen bonds and merge it with oxygen to get water. This is a much more efficient (and cleaner) process when compared to blowing up carbon-hydrogen bonds via combustion. But it is also harder and more expensive (at least today!).
Advances in Hydrogen Storage
The two challenges for hydrogen are production and storage. For now we’ll focus on an emerging platform for high density, low cost and safe storage systems based on ‘solid’ hydrogen.
