Topsoe has been selected to license hydrogen production technology for HDF Energy’s proposed BaseBlue Power plant in West Texas. The project would convert Permian Basin natural gas into hydrogen, capture carbon dioxide from the process and supply approximately 250MW of proton exchange membrane fuel-cell generation for data centres. HDF Energy is targeting electricity supply from 2030. Topsoe’s contract covers the SynCOR autothermal reforming technology, basic engineering, proprietary equipment and catalysts for hydrogen production and CO₂ capture.
The intended hydrogen production rate is approximately 400 metric tonnes a day. HDF Energy specifies a design capture rate of 98% for the carbon dioxide produced in the hydrogen-making process, representing around 1.1 million metric tonnes of CO₂ annually for compression, pipeline transport and underground storage. The capture figure is a project design target rather than a measured result from an operating plant. The electricity facility, the hydrogen process and the associated carbon transport and storage system will all require development and commissioning before the proposed service can begin.
Topsoe’s SynCOR process uses autothermal reforming, in which oxygen and steam react with a natural gas feed to produce synthesis gas. Partial oxidation inside the reactor supplies heat for the reforming reactions, reducing the need for an external fired reformer. The process uses a relatively low steam-to-carbon ratio, with reactor geometry, burners, lining and catalysts designed around high reaction temperatures. Oxygen supply, heat management and the downstream purification stages must be coordinated as part of the overall hydrogen production train.
The synthesis gas must undergo further processing before it can supply hydrogen to fuel cells. Carbon monoxide can be converted with steam in a water-gas shift reaction to produce additional hydrogen and carbon dioxide. Separation and purification stages then provide a hydrogen stream at the required quality, while the concentrated carbon dioxide stream is routed into capture and compression equipment. The exact balance of hydrogen production, auxiliary power consumption and capture performance will depend on the installed process and its operating conditions.
Electricity generation follows a separate electrochemical process. In a proton exchange membrane fuel cell, hydrogen enters the anode and oxygen from air is supplied at the cathode. The membrane allows protons to pass while electrons travel through an external circuit, producing electricity; water is formed at the cathode. Unlike combustion turbines, the fuel cells provide output through electrochemical conversion, but they still require fuel processing, cooling, controls and balance-of-plant equipment to operate as an integrated power station.
Data centre demand can change more rapidly than the conditions inside a large chemical processing unit. PEM fuel cells can vary electrical output quickly, while reforming, gas treatment and carbon capture have their own operating and control requirements. The project must therefore coordinate hydrogen supply and the fuel cell generating modules, including how variations in load are managed. HDF Energy describes the system as modular and scalable; the 250MW figure characterises the proposed generating installation, while the net electricity delivered will reflect auxiliary consumption and operating configuration.
The concentrated CO₂ stream is intended for capture before the hydrogen reaches the fuel cells, which produce water at the point of electricity generation. The 98% design capture rate covers the specified hydrogen production process and is separate from the plant’s complete greenhouse gas footprint. Natural gas supply, energy used by compressors and other equipment, transport of the captured stream and its permanent storage are all parts of the proposed operating chain. The development will require engineering and monitoring systems to substantiate capture and storage performance in service.
Topsoe will supply a defined process technology package from which HDF Energy and its engineering partners can develop the plant. The licensed scope includes specialist equipment and catalysts as well as process design, connecting the chemical conversion unit with the proposed carbon handling route. HDF Energy remains responsible for the broader power project and fuel cell arrangements. Permitting, gas supply, electrical systems and construction will determine the sequence by which these separate industrial systems can be assembled and tested.
The Texas location connects the design to two industrial systems: the Permian Basin’s natural gas supply and the electricity requirements of expanding data centre infrastructure. A dedicated hydrogen conversion and generation chain could offer an alternative to some other firm-power arrangements, but its economics depend on the cost of gas, carbon capture and storage, plant utilisation and the capital cost of the fuel cell system. Those parameters will determine whether the project can meet its proposed operating model when it reaches final design and execution.
HDF Energy plans to use BaseBlue as a replicable design for industrial users seeking firm power. In West Texas, the project timetable targets 2030 for electricity supply, with detailed integration work still required across natural gas conversion, CO₂ transport and fuel cell generation. The production rate, capture target and electrical output are connected engineering specifications, and their combined performance will be established only when the installed plant is commissioned and operated.
