Methanol marine fuels consultancy GREENMARINE and Vertoro, a Maersk-backed Dutch start-up focused on developing liquid lignin technology which can be used as a bunker fuel, has signed an agreement to jointly accelerate the market validation and commercial roll-out of lignin-alcohol as sustainable marine fuels.

“We at GREENMARINE Group are excited to join forces with Vertoro to bring their revolutionary lignin alcohol blend fuel to market,” said Fredrik Stubner, founder and CEO of GREENMARINE Group.

“This breakthrough technology redefines sustainable maritime fuels, delivering environmental benefits and cost efficiencies, paving the way for a greener, more competitive shipping industry.”

Dr. Michael Boot Boot, co-founder & co-CEO Vertoro, replied, “GREENMARINE Group has an excellent track record as a match maker for green fuel producers with engine manufacturers and shipping companies, opening many doors for us on both the fuel validation and offtake side.”

Vertoro, founded in 2017, produces liquid lignin exclusively from sustainably sourced forestry and agricultural residues by means of a patented thermochemical process. Like fossil oil, liquid lignin can be used as a platform for fuel, chemical and material applications.

Singapore-based bunker trading firm Sea Oil Petroleum Pte Ltd (Sea Oil), a wholly owned subsidiary of Thailand-listed Sea Oil Public Company Limited, has received International Sustainability and Carbon Certification (ISCC) EU certification, learned Manifold Times.

ISCC EU is a certification scheme that verifies compliance with the sustainability criteria for biofuels and bioliquids within the European Union. It ensures that biomass and biofuels used in the EU meet specific environmental and social requirements, including greenhouse gas emission reductions and traceability throughout the supply chain.

The milestone, which took place on 22 May after two months of processing, was reflective of the company’s aim to expand its bunker fuel product offerings to clients seeking sustainable solutions, Steve Goh, Head of Trading at Sea Oil, told the bunkering publication.

“It is important for the bunkering sector to remain relevant, adapt, and play an active role in supporting shipping’s decarbonisation journey,” said Mr Goh while adding that, “this is in line with our group’s green initiative and sustainability drive.”

“As such, Sea Oil seeks to do its part for climate change by giving options to support to our end users.

“By achieving ISCC EU certification, Sea Oil will be in a better position to provide green marine fuel solutions to customers embarking on this journey towards net zero.”

Manifold Times in May reported Sea Oil welcoming a Senior Bunker Trader to its team.

The company started 2025 with an expanded team on both international and local fronts.

The Directorate General of Shipping (DGS), Mumbai on 3 July issued a notice inviting comments from stakeholders on the draft circular on Biofuel bunkering Guidelines.

“Increasing global emphasis on decarbonising the maritime sector has accelerated the adoption of biofuels as a sustainable alternative to conventional marine fuels,” it explained.

“Biofuels, particularly drop-in types such as Fatty Acid Methyl Esters (FAME), Fatty Acid Ethyl Esters (FAEE), Straight Vegetable Oils (SVO), Hydrotreated Vegetable Oils (HVO), Bio-FT-diesel (bio-Fischer-Tropsch diesel) and Biomass-to-Liquid (BTL) fuels, offer considerable benefits by reducing lifecycle greenhouse gas emissions without necessitating major modifications to existing shipboard fuel systems.

“However, the absence of standardised national guidelines for biofuel bunkering operations in India introduces potential challenges related to safety, fuel quality assurance, environmental protection, and operational consistency.”

The proposed circular aims to bridge these gaps by establishing a clear regulatory framework for permitting, operational protocols, safety management, documentation, environmental safeguards, training requirements, and enforcement mechanisms specific to biofuel bunkering.

By implementing these guidelines, the Directorate seeks to ensure safe and reliable bunkering practices, promote the use of cleaner fuels in alignment with India’s environmental commitments, and support the growth of sustainable maritime infrastructure.

The guidelines are crucial for facilitating the responsible uptake of biofuels in the shipping sector, aligning Indian practices with international conventions, contributing to a modern, resilient, and environmentally conscious maritime ecosystem.

The full draft circular on biofuel bunkering guidelines can be obtained from DGS’ website here. Comments and inputs should be sent to: [email protected] and CC to: [email protected] by 18/07/2025.
