Ok, I see two semi-related assertions now:
>>> Pure CO2 and water to synfuels is still wildly energy inefficient.
> If the Hysatas electrolyzer is for real and scales up, making hydrogen is going to get way more efficient.
From the article, Synhelion has a thermal reactor now: solar radiation directed by heliostats into a thermal reactor that feeds a Fischer-Tropsch process. It seems difficult to establish relative efficiency of the whole to the Hysatas electrolyzer which is one component of a larger chain to capture and transmit energy to perform work.
If I were to assume a similar story for Hysatas where photovoltaics feed electricity to electrolyze water and a whole new infrastructure for fuel is stood up: What measure would measure and demonstrate the relative efficiency between the two processes?
- narrator 2y agoThe finding the biomass to make the methane from is the non-scalable, energy intensive part. You have to collect the biomass, load it on to a truck, ship it around on a truck, and then unload it and dispose of it after it's depleted. If you only need air, electricity and water to make the synthetic fuel, that's going to be scalable to a civilizational level scale.
- adolph 2y agoAre you suggesting scalability is the measure of efficiency?
