Carbon 280 has basically developed a liquid battery, except rather than holding energy in the traditional electrochemical sense (i.e. lithium-ion battery), they have developed a material called hidrilyte which enables them to store hydrogen in a mineral-based magnesium oil. It is one of the few technologies I have come across that manages to improve its storage capacity with each cycle rather than diminish, and CO2 is never emitted during their process.
Not many people know how to store the smallest element in the universe at nearly 700 times the pressure of our atmosphere (1 atmosphere= ~14.69 pounds per square inch). As it turns out, in the hydrogen economy, such knowledge is deeply coveted.
So when I say circular economy, I mean that a population of 10,000 generates the waste that is just the right amount to power the vehicles that are owned by these 10,000 people.
The magic mix needed to get to $1.50/kg Hydrogen – Origen Hydrogen’s solid state electrolyzer innovation
Not even the best policy environments can overcome the reality of physics and unit economics. Cheaper materials to produce more efficient and affordable electrolyzers will enable low cost production of green hydrogen, but some rather steep market milestones still need to be met. Getting electrolyzers to a scale that enables sub $1.50 / kilo of hydrogen is a major milestone that will enable incredible decarbonization across the board.
