Fieldlab Industrial Electrification has opened a dedicated pilot facility at SubZero in Rotterdam, giving industrial companies and technology developers a physical environment for testing electrification, hydrogen, and Power-to-X systems under conditions intended to be closer to commercial operation.
The facility is located in the Merwe-Vierhavens district and is designed to help technologies move from development into industrial application. FLIE said the opening brought together industry, government, research, and innovation organisations, with the site providing shared infrastructure for equipment that needs to be connected, operated, and validated before deployment at working plants.
The opening also starts three initial pilot programmes involving FlowVolta, ZEF, Equans, and TNO. The work covers flexible electrolysis, direct air capture, fuel cell operation, and practical integration of hydrogen equipment with industrial utilities and wider Power-to-X processes.
FlowVolta will test a new generation of electrolyser systems designed to vary their operation with the availability of renewable electricity. ZEF will test a direct air capture system that removes carbon dioxide from the atmosphere for integration into an alternative fuels production process.
Equans will examine different operating profiles using an Inocel fuel cell, assessing how performance changes under conditions relevant to industrial and maritime energy systems. TNO is installing a commercial electrolyser to build practical experience around hydrogen production, storage, utility integration, and connection to other Power-to-X technologies.
Auke Ferwerda, FLIE partner on behalf of Platform Zero, said: “We’re giving the Power-to-X ecosystem in South Holland a physical space to actually test ideas.”
The value of that space lies in the awkward stage between a functioning prototype and equipment that a plant operator can install with confidence. Individual technologies can perform well on dedicated rigs while still encountering problems once they are exposed to industrial power supplies, cooling systems, control architecture, safety requirements, storage equipment, maintenance routines, and upstream or downstream processes.
Electrification in process industries is rarely a matter of replacing one conventional machine with an electrical equivalent. High temperature duties, steam systems, hydrogen production, chemical feedstocks, storage, and changing electricity availability can create interactions that are difficult to reproduce at laboratory scale.
Power-to-X projects add another layer because electricity becomes an input into a chemical or fuel production chain. Electrolysers, carbon capture equipment, compression, storage, synthesis systems, and process controls have to operate together, often while responding to renewable generation or electricity prices rather than running continuously at one fixed output.
The FlowVolta trial addresses that flexibility directly. An electrolyser tied closely to renewable generation has to tolerate changing power input without sacrificing efficiency, equipment life, or hydrogen quality. Those characteristics become increasingly important where operators want to avoid buying more expensive grid electricity whenever wind or solar output falls.
TNO’s work approaches the problem from the integration side. Producing hydrogen is only one part of a working system: utilities have to support the electrolyser, gas must be handled and stored safely, and downstream equipment needs predictable pressure, flow, and purity. Weakness at any of those interfaces can undermine otherwise successful equipment.
The direct air capture project adds carbon feedstock to the same industrial chain. Captured carbon dioxide can be combined with hydrogen in synthetic fuels or chemical processes, but commercial performance depends on energy consumption, capture rates, equipment utilisation, and the efficiency of whatever process follows the capture stage.
Fuel cells create a different operating question. Their performance is well understood in controlled environments, but industrial and maritime applications can expose systems to changing loads and duty cycles. Testing several usage profiles should provide evidence on how the Inocel system behaves when output is not held at one steady point.
FLIE is backed by TNO, FME, the Port of Rotterdam Authority, InnovationQuarter, Platform Zero, and Deltalinqs, with support from the Province of South Holland. That structure puts equipment developers alongside organisations representing infrastructure, industrial users, applied research, and regional economic development.
The Rotterdam location also matters. The port contains one of Europe’s largest concentrations of refining, chemicals, logistics, energy infrastructure, and heavy industry, giving developers access to potential customers that already understand the engineering constraints surrounding industrial decarbonisation.
A dedicated fieldlab can reduce the cost and disruption of testing new equipment on an operating production site, while allowing infrastructure and knowledge to be reused across several projects. It also creates a risk familiar to demonstration programmes: technologies can remain in repeated pilots without crossing into commercial procurement.
FLIE has therefore framed the facility around industrial application rather than indefinite experimentation. The more useful measures will be technologies qualified, operating data generated, integration problems solved, and projects that leave the hall for deployment in working industrial plants.
The first pilots cover several of the technologies currently competing for industrial capital, but they also expose the less glamorous work needed to make them useful. Utilities, controls, safety systems, maintenance, and interfaces will decide whether promising equipment survives the move from a test programme into routine operation.
