Electrol™ eDiesel is Drop-In Synthetic Fuel Produced from CO2 and Electricity
Twelve’s AirPlant™ Power-to-X platform expands production of diesel fuel harnessing abundant, onshore feedstocks of CO2, water and electricity.
Diesel is essential to the global economy, underpinning transportation, industry, defense, heavy equipment and critical infrastructure. Electrol™ eDiesel offers a different way to produce it, using abundant onshore feedstocks instead of relying exclusively on the conventional petroleum-based supply chain.
Produced through Twelve’s AirPlant™ Power-to-X platform, Electrol is designed to deliver the performance and compatibility of conventional diesel while expanding the feedstocks and geographies available for fuel production. The result is a new source of diesel that can work within existing infrastructure while supporting a more distributed and resilient production model.
What is eDiesel?
eDiesel is a synthetic hydrocarbon fuel designed to perform like conventional diesel while being produced through a different process. Rather than beginning with petroleum extraction and refining, eDiesel can be synthesized from CO2, water and electricity.
Because the end product is designed for use in existing diesel engines and fuel systems, operators do not need an entirely new propulsion or distribution infrastructure. The innovation is primarily upstream: changing how the fuel is made while preserving the equipment and operating systems that already depend on diesel.
How is eDiesel Produced?
Twelve produces Electrol™ eDiesel through its AirPlant™ Power-to-X platform. Power-to-X uses electricity to convert CO2 and water into synthesis gas, or syngas, which can then be converted and upgraded into hydrocarbon fuels with the properties required for diesel applications.
This production pathway changes the geography of fuel manufacturing. Because its primary inputs can be sourced across a broader range of locations, AirPlant can be deployed where power, CO2, water, infrastructure and demand align, creating new opportunities for onshore and distributed production.
Electrol™ eDiesel
Key Attributes
Drop-in compatible. Electrol is designed for use in existing diesel engines and fuel infrastructure, allowing operators to adopt a new fuel pathway without replacing fleets, generators or fueling systems.
Equivalent performance. Electrol is designed to provide the core performance characteristics expected from conventional diesel, including energy density, portability, storage and rapid refueling.
Up to 90% lower lifecycle emissions. When produced with low-carbon electricity and appropriate inputs, Twelve’s eFuels can deliver up to 90% lower lifecycle emissions compared with conventional petroleum-derived fuels.
Synthetic hydrocarbon fuel. Electrol is diesel produced through a different molecular pathway, not a new propulsion system or alternative energy carrier requiring a separate infrastructure ecosystem.
Key Advantages
Feedstock diversification. Power-to-X expands diesel production beyond petroleum by using CO2, water and electricity as primary inputs. That creates another supply pathway for an essential industrial fuel.
Onshore production. These inputs can be sourced domestically in many regions, reducing the need for production to follow petroleum resources and supporting greater industrial and energy resilience.
Distributed production. AirPlant technology can be deployed where energy, feedstocks, infrastructure and demand converge. This creates the potential for a distributed refining network rather than dependence on a relatively concentrated set of production assets.
Long-term price predictability. Power-to-X economics are driven largely by electricity, feedstock and plant costs rather than direct exposure to crude oil markets. That can create greater long-term visibility for customers seeking more predictable fuel economics.
Infrastructure compatibility. Drop-in compatibility preserves the value of existing engines, storage systems, distribution networks and maintenance infrastructure. The production technology changes without requiring the downstream system to be rebuilt.
Supply-chain resilience. Additional feedstocks, production nodes and geographies create greater optionality when conventional markets face refinery constraints, geopolitical disruption or supply-chain volatility.
Key Applications
Electrol is particularly relevant where energy density, portability, rapid refueling and reliability remain operational requirements. These applications often involve long asset lives, demanding duty cycles or infrastructure where diesel continues to solve a difficult energy and logistics problem.
Heavy-Duty Transportation. Long-haul trucking and freight require range, rapid refueling and high asset utilization. Drop-in eDiesel can diversify fuel supply while preserving existing fleets and fueling infrastructure.
Defense & Emergency Operations. Military, disaster-response and emergency operations depend on reliable fuel logistics, often across long or vulnerable supply chains. Distributed Power-to-X production can create additional options for producing fuel closer to demand.
Heavy Equipment. Construction machinery, excavators, loaders, generators and other equipment frequently operate under sustained loads and in locations where charging infrastructure is limited. Tokyu Construction cited this challenge directly in its investment in Twelve, noting that the construction industry has limited options for reducing emissions from heavy machinery and identifying Electrol™ diesel as a synthetic fuel with potential to support decarbonization across heavy-equipment applications.
Mining & Remote Operations. Remote industrial sites need energy that can be transported, stored and dispatched where required. Synthetic diesel retains those advantages while introducing a more flexible upstream production pathway.
Data Centers. Data centers rely on diesel backup generation to maintain power during outages, grid constraints and other disruptions. Because backup power also supports cooling and thermal-management systems, fuel reliability can be critical to maintaining both compute and cooling continuity.
Critical Infrastructure. Hospitals, telecommunications networks, industrial sites and distributed power systems depend on storable fuel that can be dispatched immediately when needed. Electrol can diversify that supply while preserving existing backup-generation infrastructure.
Agriculture. Tractors, combines and other agricultural equipment operate under demanding conditions and narrow seasonal windows. Drop-in eDiesel can provide another source of fuel where availability, portability and rapid refueling remain essential.
Expanding the Diesel Production Base with the AirPlant™ Distributed Refining Network
Diesel remains embedded across freight, industry, defense, agriculture and critical infrastructure, making production diversity a strategic concern. Dependence on a single dominant pathway concentrates exposure to petroleum feedstocks, refining capacity and the global supply chains connecting them.
Power-to-X expands that production base by enabling diesel to be manufactured from a different set of inputs and across a broader range of geographies. Electrol™ eDiesel brings that capability into an existing global fuel market while preserving the performance and infrastructure advantages that make diesel useful.
The broader opportunity is the AirPlant distributed refining network, with production nodes located where power, CO2, water, infrastructure and demand align. For industries where diesel remains essential, that creates a more diversified production system built around more feedstocks, more locations and more ways to supply the fuel.
