Common questions about the platform, the SAF market, and how to get involved.
About the platform
e-fuels·com is a market infrastructure platform connecting SAF producers, offtake buyers, and capital. We're building four modules: Market Intelligence (price indices, project data), SAF Trading (spot, forward, book-and-claim), Deal Room (structured offtake and finance), and Network Intelligence. Currently in private beta, onboarding founding network members.
The platform serves the full SAF value chain: producers at every development stage, offtake buyers (airlines, shipping companies), capital providers (infrastructure funds, DFIs), and technology and service providers. If you operate anywhere in the sustainable fuels market, there's a place here.
Market Intelligence launches 2026 for registered network members. The Deal Room opens in 2028. SAF Trading goes live in 2029. Early registration gives you access to each module as it launches, at permanent founder pricing.
We charge subscription fees for Market Intelligence access, transaction fees on deals closed through the Deal Room, and trading fees on the exchange. We don't sell participant data, take positions, or accept advertising. Our neutrality is commercially essential · the platform only works if every side of the market trusts it.
For producers
No. The producer registry covers every development stage · from feasibility through to operating assets. Earlier-stage projects are often the most valuable for the network, as they're the ones that need offtake and capital connections most urgently.
A member of our team reviews your submission personally and responds within 48 hours. We'll confirm your registration, discuss your project's needs, and map you to relevant buyers and capital sources. You get access to pre-launch Market Intelligence data immediately after onboarding.
Yes. You control exactly what information is shared and with whom. Detailed project data is only shared through the Deal Room under mutual NDA · never without your explicit consent. We don't aggregate or resell participant data.
The first 100 network members registered are locked in at a permanently discounted rate for every future subscription tier. This rate never increases regardless of what public pricing becomes. No minimum commitment period.
SAF & market
Sustainable Aviation Fuel (SAF) is a drop-in fuel for jet engines produced from non-petroleum sources including waste feedstocks, agricultural residues, green hydrogen, and captured CO₂. Chemically compatible with existing aircraft and infrastructure, SAF reduces lifecycle CO₂ by 50–99% compared to conventional jet fuel depending on pathway and feedstock.
HEFA (Hydroprocessed Esters and Fatty Acids) is currently dominant, using waste oils and fats. ATJ (Alcohol-to-Jet) converts alcohols into jet fuel. FT (Fischer-Tropsch) converts syngas from biomass into hydrocarbons. PtL (Power-to-Liquid) uses green hydrogen and captured CO₂ · highly scalable due to independence from biogenic feedstocks. PBtL (Plasma-Biomass-to-Liquid) is an emerging pathway using plasma technology to convert CO₂ into synthesis gas for fuel production. See the full technology comparison →
ReFuelEU Aviation is the EU regulation mandating SAF blending at EU airports · starting at 2% in 2025, rising to 70% by 2050. It applies to all fuel suppliers at EU airports and all airlines departing EU airports. The mandate creates a legally guaranteed demand floor underpinning long-term offtake contracts.
Book-and-claim allows the sustainability attributes of SAF to be separated from the physical fuel and traded as certificates. A buyer can claim the CO₂ benefit of SAF produced elsewhere · eliminating complex physical delivery requirements and enabling a global market to function at scale.
Access & pricing
Pricing is not yet publicly listed · the platform is in private beta. Founding network members are locked in at a preferential rate that will never increase. Once the platform launches publicly, pricing will be published by tier.
Basic network membership including a public listing in the producer registry will be available at no charge. Market Intelligence, Deal Room access, and trading are subscription or transaction-fee based.
Use the Express Interest form. Tell us your role and what you're looking for. We'll onboard you to the right part of the network and connect you with relevant counterparties.
Trust, data & operations
Every participant controls what data is visible and to whom. Aggregated market data · such as price indices and capacity totals · never reveals individual project details. Deal Room interactions are protected by mutual confidentiality terms, and raw data is never shared with competitors. Our revenue comes from subscriptions and fees, not from selling participant data.
The platform facilitates introductions and provides the infrastructure for structured deal-making, but is not a party to any transaction between participants. All offtake agreements and investment commitments are bilateral contracts between the parties. We recommend that all deals include appropriate dispute resolution clauses. German law and Munich jurisdiction apply to platform use.
Market Intelligence data will be available via API and CSV export from launch. We're building with interoperability in mind · including alignment with CORSIA reporting frameworks, RSB registry standards, and enterprise data formats used by commodity desks, rating agencies, and DFIs. Detailed API documentation will be published closer to the 2026 launch.
e-fuels·com is a global platform. The project registry already covers facilities in 22 countries across Europe, North America, the Middle East, Asia-Pacific, and Latin America. Regulatory monitoring covers ReFuelEU (EU), CORSIA (ICAO, global), and the US Inflation Reduction Act. As new SAF mandates emerge · including in the UK, Japan, India, and Brazil · we'll add those to the policy monitor.
Every producer and project is manually reviewed before inclusion. We cross-reference against public filings, EASA and ICAO databases, published offtake announcements, and direct dialogue with project teams. Data carries confidence ratings (1–5) so users can assess reliability. We do not auto-scrape or rely on unverified self-reporting.
