In recent years, the rapid increase of CO2 emission in the atmosphere and the resulting issues such as global warming and climate change have become significant barriers to environmental sustainability. My study focuses on the conventional and advanced thermal conversion of fast-growing biomass like macroalgae (seaweed) and microalgae for producing 3rd generation biofuel and biochar, aiming to establish a leading technology of algal biochar-biofuel system (ABBS) in Europe, and eventually find a cost-effective and environmental-friendly alternative to fossil fuels.

At the same time, my project regards algal biochar as the by-product of ABBS to significantly reduce the cost of algal biofuel, making it a competitive commercial product in Europe. Up to now, a wastewater-derived microalgae biochar was synthesised and proven safe to use as soil amendment agent with no phytotoxicity.

In addition, great electrochemical performance of as-obtained biochar makes it a potential promising battery and supercapacitor electrode material.
