About Us
Founding Story
Frontier Fuels is a leading supplier of advanced marine biofuels in Germany.
Founded in 2023, we have quickly earned a reputation for reliability, innovation, and a commitment to real sustainability. As a physical supplier, we provide the shipping industry with cost-effective, high-quality, low-carbon fuels. From Hamburg and Bremerhaven to Cuxhaven, Kiel, and Rostock, we deliver across all major German ports — by truck or barge, wherever our customers need us.
Frontier Fuels was founded by a team with deep expertise across energy engineering, marine biofuels, and advanced data science. Led by Luc Siebinga, former developer of Marine Biofuels at VARO Energy, and Johann Maack, a Data Scientist with a background in consulting and AI research, Frontier Fuels blends technical innovation with operational expertise.
Our mission is clear: to drive the transformation of the shipping industry with cleaner, smarter fuels. We are passionate about enabling our customers with renewable energy solutions that meet today’s demands and fuel a better tomorrow — helping you stay competitive while making a lasting impact.
At Frontier Fuels, a sustainable future isn’t a goal — it’s already in motion.
