In an era where sustainable energy solutions are paramount, Temitope Daramola’s groundbreaking research on algae biomass purification is opening new pathways for cleaner biofuel production. His innovative work at Old Dominion University’s Biomass Research Laboratory has demonstrated a revolutionary, eco-friendly method to process algae for biofuel production, potentially transforming the renewable energy landscape.

“The challenge with using algae for biofuel has always been its high ash content,” explains Engr. Daramola. “This mineral content reduces combustion efficiency and causes equipment fouling, making it less practical for large-scale biofuel production.”

In his recent breakthrough study, Daramola and his team developed a green deashing strategy using nitrilotriacetic acid (NTA) and deionised water to purify algae biomass. The results have been remarkable, achieving up to 83% ash removal in some species.

A Game-Changing Approach

When asked about what sets this method apart, Daramola highlights its environmental sustainability. “Unlike traditional acid leaching methods, our approach is eco-friendly and can be recycled multiple times. We’re not just solving the ash problem – we’re doing it in a way that aligns with circular bioeconomy goals.”

The research focused on three different algae species, with Scenedesmus showing particularly promising results. “We managed to reduce the ash content from 15.2% to 3.8% while preserving the biomass’s essential organic components,” Daramola noted. “This is crucial because it means we’re not sacrificing the energy-producing potential of the algae while cleaning it.”

Temperature: A Critical Factor

One of the study’s key findings was the significant role of temperature in the deashing process. “We discovered that increasing the treatment temperature from 90°C to 130°C substantially improved ash removal efficiency,” explains Daramola. “This insight is vital for scaling up the process for industrial applications.”

The research also revealed that combining NTA treatment with deionised water rinses provided the best results, effectively removing both surface-bound impurities and deeply embedded metallic compounds.

Looking Ahead: Impact and Applications

The implications of this research extend beyond the laboratory. “What we’ve developed here could significantly impact the biofuel industry,” Daramola states. “Cleaner algal biomass means more efficient biofuel production, less equipment damage, and ultimately, a more viable renewable energy source.”

Daramola’s work has also addressed one of the major criticisms of biofuel production – its environmental impact. “By using biodegradable chemicals and implementing a recycling process, we’re ensuring that the solution doesn’t create new environmental problems while solving existing ones.”

The Path Forward

Looking to the future, Daramola and his team are focused on scaling up the process for industrial applications. “We’re currently working on optimising the recycling process and exploring ways to make this technology commercially viable,” he shares. “The goal is to make algal biofuels a practical, sustainable alternative to fossil fuels.”

This research, funded by Sandia National Laboratories through the U.S. Department of Energy, represents a significant step forward in sustainable energy production. As the world continues to seek alternatives to fossil fuels, Daramola’s work offers a promising pathway toward cleaner, more efficient biofuel production.

“The energy challenges we face today require innovative solutions,” Daramola concludes. “Our work shows that with the right approach, we can overcome technical barriers while maintaining environmental responsibility. That’s what sustainable development is all about.”

Through this groundbreaking research, Daramola and his team are not just advancing scientific understanding – they’re helping to shape a more sustainable energy future.
