Researchers have developed new strains of marine algae that produce up to three times more biomass than conventional varieties, opening up the possibility of using them as fuel for ships and aircraft, according to APNEWS, stated ClickPetroleoEGas.
The breakthrough comes from scientists at the Woods Hole Oceanographic Institution in the United States, who have been working on cultivating fast-growing seaweed varieties. These algae can be converted into liquid biofuel using a process called hydrothermal liquefaction, which applies heat and pressure to organic material without relying on petroleum, the report said.
The fuel produced from algae could serve as an alternative to conventional fossil fuels used in aviation and maritime transport, sectors that currently depend heavily on petroleum-based energy sources. Researchers say algae-based fuels are among the few options that can be used without major changes to existing engines.
Despite the technological progress, the report highlighted a major hurdle in scaling up production. According to scientists, energy companies are reluctant to invest in large-scale algae farming without clear market demand, while producers are unwilling to expand cultivation without guaranteed buyers. This has created a cycle that continues to slow commercial development of the technology.
Marine scientist Scott Lindell, who led research funded by the US Department of Energy, indicated that the challenge is not the science but the lack of market certainty. The sector has struggled for years to move beyond pilot stages due to this gap between supply and demand.
Algae-based biofuels are considered a promising renewable energy source because of their fast growth rates and ability to produce high amounts of biomass. Studies have shown that such fuels can help reduce greenhouse gas emissions and provide a sustainable alternative to fossil fuels.
However, experts say that wider adoption will depend on policy support, long-term investment and the development of a stable market for algae-derived fuels, especially in energy-intensive industries like shipping and aviation.
