> than making hydrogen via electrolysis
i'd say synth gas would be more versatile option. Also they can like Iceland export the energy as aluminum or similar products taking a lot of energy to produce. (and a bit dreaming - i think Andes is the place to build a large rail gun style space launcher, and not just for one launch per week like, i mean large spaceport launching stuff non-stop and this is where beside launch energy you'd need energy to produce fuel for the upper stages)
- bryanlarsen 5y agoThe viability of synthetic gas really depends on the price of your carbon source. Direct air capture of CO2 is pretty expensive but subsidies can make it work. Ammonia is the conventional option for long distance shipping of hydrogen. The ammonia can be used directly as the fuel or cracked at the destination for its hydrogen.
- boibombeiro 5y agoSomething related. Brazil exports more water in form of grains and meat ("virtual water") to China than the huge South–North Water Transfer Project.
- ncmncm 5y agoMaking synth gas or ammonia would give them a multitude of markets competing for the product, vs. just China at the end of a wire. But Chile probably needs a lot of capital to build out the solar arrays. A guarantee like that might be necessary to get China to pony up.
