Plankton Power: A Microscopic Hope for Sustainable Fuel
Plankton are a diverse group of marine organisms, but for biofuel production, the focus is on phytoplankton, specifically their remarkable ability to produce oils and fats—the key ingredients for biodiesel and other biofuels. Phytoplankton can be grown in large ponds or bioreactors. Open pond systems mimic natural plankton blooms. Nutrient levels, water temperature, and even light intensity are carefully controlled to create ideal environments. Some phytoplankton species require periods of darkness to trigger oil production. However, open ponds are susceptible to contamination by unwanted organisms and environmental fluctuations. Bioreactors offer a more controlled setting. Scientists can fine-tune light wavelengths, CO2 concentration, and nutrient delivery to create the perfect recipe for rapid plankton growth. These closed systems also minimize contamination risks and allow for efficient harvesting of plankton biomass. However, maintaining sterile conditions and the high energy demands of running bioreactors can be a significant cost factor
