Manshu Agarwal, HutanBio: Algae’s one in a trillion chance for success

Date:

This week Oscar is joined by Manshu Agarwal, CEO, HutanBio a UK based company aiming to commercialise the use of Algae as a feedstock for sustainable aviation fuel production. 

Manshu has watched the algae story play out once already. A chemical engineer by training, he cut his teeth at Sapphire Energy and then Synthetic Genomics — two ventures that between them raised hundreds of millions of dollars chasing algae biofuels, only to run into the same wall: the biology simply wasn’t good enough to get costs down. Now at HutanBio, he’s back for round two, armed with what he believes is the missing piece.

That piece is Spherica — an entirely new class of algae, discovered after HutanBio’s founder spent a decade bioprospecting the oceans, screening a trillion organisms to find roughly 400 candidates and one genuine outlier. Spherica has a thick cell wall and packs around 300 thylakoid layers versus the 6-10 found in typical strains — translating into three times the oil productivity.

Agrawal walks through why that matters commercially: HutanBio is targeting under $1/litre at small scale and around 40 cents/litre (roughly $62/barrel) at full scale, using vertical, low-footprint photobioreactor systems developed first in Malaysia and now being scaled toward coastal deserts, starting with an MOU in Oman. 

He’s candid about algae’s credibility problem after two decades of hype and underdelivery — but argues the underlying case, heavy transport still has no cost-competitive liquid fuel alternative, hasn’t gone away, and that Spherica is the platform that finally gives algae a real shot at cost parity.
