Pyrolysis bio-oils are produced by the thermal decomposition of biomass by heating in the absence of oxygen at more than 500 °C; fast pyrolysis of biomass is much less expensive than biomass conversion technologies based on gasification or fermentation processes. In comparison, increasing the H/C eff ratio of pyrolysis oil from 0 to 1.4

At this stage, cost estimates are uncertain, since methane cracking is not yet a fully mature technology. However, preliminary calculations show that it could achieve costs of €1.9 But these past attempts were limited by issues such as carbon clogging and low conversion rates.

Researchers at Tsinghua University in China have shown that sugarcane juice is a good feedstock for biodiesel production, when used to support the growth of the alga Chlorella protothecoides by heterotrophic fermentation. Conversion ratios of sugar/biomass and sugar/oil using SCH were 15.2 There are bottlenecks in this pathway.

The Coskata process can produce more than 100 gallons of ethanol per ton of dry, ash-free biomass material at a cost competitive with expected gasoline prices—around $1.00 Actual production cost will vary, either below or above $1.00 per gallon, based on the cost of feedstock and the cost of power for the specific plant, he noted.

Every time there is a conversion of energy from one form to another there are efficiency losses – a concept known as ‘energy vector transition’. The cost of platinum makes hydrogen fuel cells an expensive proposition even in comparison to lithium-ion batteries. Hydrogen ions are highly acidic and thus highly corrosive.

The 1979 Iranian crisis and related oil price shock accelerated Brazil’s conversion of its gasoline supply and automobile fleet.
