It is known that larger
hydrocarbon molecules like ethane and propane can also form hydrates, although longer molecules (butanes, pentanes) can not fit into the water cage structure and tend to destabilise the formation of hydrates.
And there is no reason to think that the R. eutropha could not be made to generate other products — perhaps complex
hydrocarbon molecules like those found in fossil fuels or even the whole range of chemicals currently synthesized from polluting resources, such as fertilizers.

Algae can also be used for biomanufacturing: Microscopic algae are turned into a living machine that can be genetically programmed to produce
molecules like lipids and
hydrocarbons ideally suited for biofuels.
Consequently, when the monomer
molecules are heated at 140 degree C for up to 20 hours, they line themselves up so that all the acrylate ends point in one direction and all the
hydrocarbon tails in the other —
like matches in a box.
Some of these
hydrocarbons are very light,
like methane gas — just a single carbon
molecule attached to three hydrogen
molecules.
The first step in such an electrolytic approach is splitting CO2, a tough, stable
molecule, into oxygen and carbon monoxide (CO), a slightly more energy - rich
molecule that can form the basis for
hydrocarbon fuels
like methanol.
Some of those large
molecules are
like small sheets of graphite with hydrogen attached to them: we call these polycyclic aromatic
hydrocarbons and they can be found in terrestrial counterparts
like mothballs, for example.
