The annual harvest is used as feedstock for local village - scale charcoal retorts (thus minimizing haulage energy needs) with simple fairly efficient retorts converting about 67 % of the wood's carbon to charcoal, with the rest mostly going into
hot hydrocarbon gasses that hold around 28 % of the wood's energy potential.

As the
hot hydrothermal fluid flows through this mud, it «cooks» organic material, forming methane (natural
gas) and oil - like
hydrocarbons.
That water also has to be
hot to separate the clingy
hydrocarbon — at least 50 degrees Celsius, which requires burning natural
gas to heat it.
The mixture of
hot, molten rock and
hydrocarbon - bearing coals is thought to have set the stage for massive greenhouse
gas release and global - scale climate change.
In the greater NZ region, we have undersea
hot springs (hydrothermal vents of the Kermadecs), marine
hydrocarbon seeps and
gas hydrates (offshore eastern North Island — possible analogues for oceans on Icy Worlds), and terrestrial (on land)
hot springs in the Taupo Volcanic Zone and elsewhere around the country.
The net effect is that the chemistry of the
hot gas mixture favors growth from small
hydrocarbons to larger ones with PAHs commonly being one of the end products.
