Phyllostachys nuda (bamboo) was evaluated for biofuel production using hydrothermal liquefaction. The measured biocrude mass and carbon recovery were 35.6 wt% and 53.1 wt% at 300 °C and 10 min, conditions which correspond to a mild reaction kinetic severity factor of approximately 7 and without the addition of catalyst. Technoeconomic analysis projected an Nth-plant break-even selling price of 2.75 USD per gasoline gallon equivalent (gge). This is a plant-gate production cost and is appropriately compared with wholesale rather than retail distillate prices. Well-to-wheel analysis indicated that bamboo-derived biofuel emits 3.5 g CO2-eq. MJ−1, corresponding to a carbon abatement cost of 35.2 USD per ton CO2 with the direct land-use change soil-carbon credit and 43.8 USD per ton CO2 without it. A first-order scaling estimate suggests that, under the yield and conversion assumptions used here, bamboo HTL could supply an energy equivalent of current U.S. corn-ethanol output using roughly 13% of the corresponding cultivated land area, a theoretical potential rather than a demonstrated supply outcome. Under the modeled Nth-plant conditions, an HTL biorefinery using fast-growing bamboo shows substantial economic and environmental potential.
