Scientists Have Found An Unlikely Alternative To Gasoline. It Could Cost About $2.75 A Gallon.

Scientists have identified an unlikely source of transportation fuel that could cost as little as $2.75 a gallon to produce at commercial scale, potentially offering an alternative to petroleum-based gasoline and diesel while generating substantially lower greenhouse gas emissions.

The source is bamboo, a fast-growing grass more commonly associated with furniture, construction and household products. Researchers at Worcester Polytechnic Institute (WPI) in Massachusetts have found that it can be converted into a crude-like oil suitable for further processing into liquid transportation fuels.

Their findings, published in the journal ''Sustainable Energy & Fuels," combine laboratory experiments with economic and environmental modeling to assess whether bamboo could become a commercially competitive fuel source.

The study estimates that bamboo-derived fuel could be produced for $2.75 per gasoline-gallon equivalent under mature commercial-scale conditions. That figure represents a modeled production cost, not a retail pump price, and does not establish what consumers would eventually pay at gas stations.

Researchers also found that the fuel could have greenhouse gas emissions 26 times lower than conventional petroleum diesel under the assumptions used in their life-cycle assessment.

"Our study suggests bamboo has a role to play in the future of fuel," said Michael Timko, professor and head of WPI's Department of Chemical Engineering, in the university's Oct. 14 announcement.

Timko and fellow researchers Timothy Woodard, Charles Cai of Aalto University in Finland and James Walters of Avos BioEnergy examined whether bamboo could offer an economical alternative to traditional fuel crops.

One of the more striking findings concerns farmland. The researchers estimate that bamboo could produce the energy equivalent of current U.S. corn ethanol output using roughly 13% of the cultivated land, based on their assumptions about crop yields and fuel conversion.

The researchers used a process called hydrothermal liquefaction, which subjects plant material to high temperatures and pressure in the presence of water. The process converts biomass into biocrude, an oil-like substance that can be further refined into transportation fuels.

Unlike conventional ethanol production, which commonly uses fermentation to convert sugars into alcohol, hydrothermal liquefaction processes plant material through heat, pressure and chemical reactions.

The research team tested Phyllostachys nuda, a species of bamboo, and reported a biocrude yield of 35.6% by mass under laboratory conditions of 300 degrees Celsius for 10 minutes without adding a catalyst.

Using the researchers' assumptions about soil carbon storage, producing and using bamboo-derived fuel would generate approximately 3.5 grams of carbon dioxide equivalent for each megajoule of energy.

That estimate covers the modeled fuel life cycle, rather than only the emissions produced when the fuel is burned. The team calculated an emissions-reduction cost of approximately $35.20 for each metric ton of carbon dioxide equivalent avoided when accounting for the modeled soil carbon benefit from land-use change. Without that benefit, the cost increased to $43.80.

Those results depend on the study's production and land-use assumptions and have not yet been demonstrated through commercial-scale fuel operations.

Corn dominates the U.S. ethanol industry, with most gasoline sold in the country containing a mixture of petroleum-derived gasoline and ethanol.

Nearly all fuel ethanol produced in the United States comes from corn starch, according to the U.S. Energy Information Administration. The most common gasoline blend contains approximately 10% ethanol, commonly known as E10.

The U.S. Department of Energy's Alternative Fuels Data Center identifies non-food plant materials, including grasses, agricultural residues and wood waste, as potential sources of advanced biofuels.

Such materials can sometimes be grown on land unsuitable for conventional food crops, although collecting, transporting and processing them economically remains a challenge. Bamboo's potential advantage is its combination of rapid growth, high biomass yields and relatively low agricultural requirements.

The researchers' farmland comparison remains a theoretical estimate, however, rather than evidence that existing bamboo cultivation could immediately replace the country's corn ethanol production.

Commercial adoption would also require further work to establish reliable bamboo supplies, expand processing capacity and refine the resulting biocrude into fuels meeting transportation standards.

The research arrives as the United States continues expanding its renewable fuel requirements.

In March, the Environmental Protection Agency finalized renewable fuel standards for 2026 and 2027, establishing volume requirements for several categories of biofuels, including cellulosic fuels made from plant fibers.

The agency also partially waived the 2025 cellulosic biofuel requirement because actual production fell short of the previously established target.

WPI's researchers believe bamboo could eventually contribute to fuel production for sectors where replacing petroleum with electricity remains difficult, including heavy-duty transportation and aviation.
