NIAGARA aims to transform European biogenic waste streams—such as wastewater, digestate, and sewage sludge—together with microalgae into advanced biofuels for clean electricity generation through innovative fuel cell applications. The process integrates an advanced hydrothermal carbonisation (HTC) technology to convert biogenic wastes and microalgae into hydrochar and an aqueous phase. The hydrochar is gasified, while the liquid phase undergoes aqueous phase reforming (APR). Captured CO₂ is then reused through advanced sorbent technologies, and the resulting biofuel powers solid oxide fuel cells (SOFCs).
NIAGARA’s integrated process is designed to operate with a minimal carbon footprint and holds the potential to become carbon-negative over time, driving progress toward a circular, low-carbon bioeconomy.
