Hydrogen sources across the liquid organic hydrogen carriers market span green, blue, grey, pink and turquoise hydrogen, deployed at pilot, demonstration, commercial and utility scale.
Infrastructure types run from production facilities and export terminals through import terminals and industrial hubs to refuelling and distributed networks.
LOHC stands for liquid organic hydrogen carrier, the technology that binds hydrogen into a liquid for transport and releases it where required.
Source, scale and infrastructure are connected because what a project is for determines how large it must be and what facilities it needs.
An export corridor carrying renewable hydrogen from one continent to another requires utility-scale plant at both ends and terminals to connect them.
A demonstration project proving a technology requires none of that, and the two are barely comparable as commercial propositions.
Much of this market's current activity sits at the demonstration end, which is the honest starting point for understanding its infrastructure.
Scale is also what determines whether a project is financeable, since infrastructure investors assess projects on committed offtake rather than on technology merit.
The mismatch between where low-cost renewable hydrogen can be produced and where industrial demand sits is what creates the corridors this infrastructure serves.
That mismatch is geographic rather than technical, and it is the underlying reason hydrogen transport is a market at all.
This page describes sources, scales and facilities as market categories and provides no engineering, handling or safety guidance.
The hydrogen industry uses a colour convention to describe how hydrogen was produced rather than any property of the gas itself.
Hydrogen produced by any route is chemically the same substance, and the colours describe production history rather than the product.
It is worth stating plainly that this taxonomy is an industry convention rather than a regulated classification, and usage varies between jurisdictions and organisations.
Green hydrogen describes hydrogen produced by electrolysis of water using renewable electricity.
It accounts for the largest source concentration in this market, consistent with demand that rests on decarbonisation rather than on cost.
Blue hydrogen describes hydrogen produced from natural gas with the resulting carbon dioxide captured and stored.
Grey hydrogen describes production from natural gas without capture, which is how the great majority of hydrogen is made today.
Pink hydrogen describes electrolysis powered by nuclear electricity, and turquoise describes production routes yielding solid carbon rather than carbon dioxide.
Because definitions are not standardised, the same project may be described differently by different parties, particularly at the boundary between blue and grey.
That imprecision matters commercially, since offtake agreements and public funding frequently specify a colour without a universally agreed definition behind it.
Buyers and developers generally define their own criteria contractually rather than relying on the convention alone.
For LOHC providers the source colour matters less technically than commercially, since it determines which projects qualify for support and offtake.
Certification schemes have begun to replace the colour convention with measured carbon intensity thresholds, which is a more precise basis and is gradually displacing colour language in contracts.
The capacity segmentation in this market runs across four scales, and they describe genuinely different kinds of project rather than sizes of one kind.
Pilot scale installations prove that a technology works, typically at a research site or an industrial partner's facility.
They are funded as development rather than as infrastructure, and their purpose is knowledge rather than delivered hydrogen.
Demonstration plants operate at a scale intended to show commercial viability rather than technical feasibility.
They represent the largest capacity segment in this market today, which is the clearest single indicator of how early this market is.
Demonstration projects frequently carry public funding, since their purpose is to establish precedent that private capital will not finance alone.
Commercial scale describes plant built to operate as a business rather than to prove anything, and it is the fastest-growing segment.
The transition from demonstration to commercial is where this market's growth actually comes from, and it is what the forecast horizon is built around.
Utility scale describes the largest installations, associated with major export corridors and national infrastructure programmes.
Very few utility-scale LOHC projects are operating, and those announced are largely at development rather than construction stage.
Describing this progression honestly is more useful than presenting the market as commercially established, which it is not yet.
The gap between announced and operating capacity is substantial across hydrogen generally, and this market is no exception.
Scale also determines who can participate, since utility-scale projects require balance sheets and delivery capability that exclude most specialist providers acting alone.
Hydrogen production facilities are where the chain begins, and LOHC infrastructure attaches to them through co-located hydrogenation plant.
Co-location is necessary because moving hydrogen even a short distance before loading undermines the reason for using a carrier at all.
The plant involved is described among the systems this infrastructure is built around, and its capacity bounds what a production site can dispatch.
Export terminals connect the loaded carrier to marine or overland transport, and they are where LOHC's infrastructure argument is most visible.
A terminal handling a liquid at ambient conditions requires tankage and loading arrangements broadly comparable to conventional liquid fuel handling.
That comparability is what allows existing terminal infrastructure to be adapted rather than replaced, which is the technology's principal capital advantage.
Terminal operators are a distinct customer group in this market, since they own the infrastructure through which a corridor must pass.
Their participation is frequently the practical gate on whether a corridor develops, regardless of technology readiness at either end.
Export terminals concentrate at locations combining renewable resource with existing port infrastructure and energy export relationships.
Australia, Chile, the Gulf states and parts of northern Europe all hold positions on that basis.
The returning unloaded carrier must also be handled at these terminals, which is an infrastructure requirement conventional fuel export does not carry.
That two-way requirement is straightforward technically but must be planned and costed, and it is easily underestimated in project development.
Import terminals receive loaded carrier and are where dehydrogenation plant is generally located.
That location matters commercially because dehydrogenation requires energy, and an industrial location may offer heat or utilities a standalone terminal would not.
Import terminals concentrate in industrial regions with hydrogen demand, principally north west Europe, Japan and South Korea.
Port and industrial cluster infrastructure in the Netherlands and Belgium positions those countries as European import gateways.
Japan and South Korea have both adopted national hydrogen strategies and are structurally dependent on energy imports, which makes them natural import markets.
Industrial hydrogen hubs group production, storage, distribution and consumption within a defined area rather than connecting distant points.
The hub model is the principal organising structure for hydrogen investment in the United States and features in European programmes as well.
Hubs reduce the transport distance that made hydrogen logistics difficult, which changes what carriers are needed and why.
Hubs exist to serve industrial demand, and the industries this infrastructure ultimately serves determine what a hub must actually deliver.
Within a hub, LOHC's role is more likely to be storage and local distribution than long-distance transport.
That difference in role changes which technology categories are relevant, since storage solutions rather than transport chains become the requirement.
Hub development is generally publicly supported, which means participation depends on programme selection as much as on commercial merit.
Hub participation is generally competitive, with public programmes selecting among proposals rather than funding all of them.
Hydrogen refuelling infrastructure serves vehicles, and it is the application where hydrogen reaches an end user most directly.
Refuelling stations require hydrogen at high purity and at pressure, which means dehydrogenation and conditioning at or near the point of dispensing.
The distributed nature of refuelling is what makes it commercially difficult, since each site requires equipment that a central facility would not.
Mobile and modular LOHC solutions are relevant here precisely because fixed infrastructure at every site is hard to justify.
Refuelling demand has developed more slowly than early hydrogen mobility projections suggested, which is a market fact worth stating.
Heavy transport, buses and captive fleets have proved more viable than passenger vehicles, and they concentrate demand into fewer locations.
That concentration improves the economics of supply infrastructure considerably compared with dispersed passenger refuelling.
Distributed hydrogen networks describe supply to many smaller points of use rather than to a few large ones.
The model suits industrial gas company operations, since distributing gases to dispersed customers is what that industry already does.
LOHC's ambient-condition handling is genuinely advantageous in distributed supply, since delivery resembles conventional liquid delivery.
Against that, dehydrogenation at each delivery point adds equipment and cost that centralised supply would avoid.
How that trade-off resolves depends on the density and size of demand, and it is assessed project by project rather than in general.
Utilisation rates determine refuelling economics more than any other factor, and low utilisation has been the principal difficulty across deployed networks so far.
Green hydrogen describes hydrogen produced by electrolysis of water using renewable electricity. The colour taxonomy describes production history rather than any property of the gas, and it is an industry convention rather than a regulated classification.
Both are produced from natural gas; blue includes capture and storage of the resulting carbon dioxide while grey does not. Definitions are not standardised, so the same project may be described differently by different parties at that boundary.
An export terminal connects loaded carrier to marine or overland transport. Because an LOHC is handled at ambient conditions, such a terminal requires tankage and loading arrangements broadly comparable to conventional liquid fuel handling.
A hub groups hydrogen production, storage, distribution and consumption within a defined area rather than connecting distant points. Within a hub, LOHC's role is more likely to be storage and local distribution than long-distance transport.
