Why Aquatic Biomass
If our energy would be derived from recent photosynthesis there would be no net increase in CO2

Why Aquatic Biomass
What source to use for fuels?
Depends on:• (Agricultural) land needed• Freshwater demand• Productivity
Microalgae -> lipids -> biodiesel

4Challenge the future
Current status
• Microalgal cultivation takes place at small to medium scale.
• Only economically interesting for high-value products
• Topic of research worldwide

5Challenge the future
Key Research Questions
• Increase lipid productivity • Light input• Carbon allocation in microalgae
• Enhance solid liquid separation after cultivation • 2 g / L starting concentration
• Come up with large scale processes• Size of Portugal needed for
transport fuel Europe• Marine environment

6Challenge the future
Future Prospects
• More philosophical than technical -> need renewable liquid fuels -> algae are the best candidate
• Must be cheaper than drilling a hole in the ground
• More than scientific breakthroughs are needed

7Challenge the future
Role of TUD
• If society wants renewable fuels, TUD can help supplying the solutions to do so
• The core of the process is biotechnology
• But we need maritime engineering, process engineering, chemical engineering …
