Green H₂ is critical to achieving sustainability targets in the industrial sector. To accelerate the H₂ ramp-up, the technology company Siemens will be supporting companies in the H₂ industry with software tools based on generative artificial intelligence. Especially in H₂ production, these new solutions are intended to help significantly simplify the design, engineering and automation of H₂ production plants, enabling a quicker scale-up of H₂ production.

The new H₂ plant configurator is an intelligent chatbot based on generative artificial intelligence which enables users to create plant designs for H₂ production. In an iterative process, the configurator is fed with the desired design characteristics of a production plant. The AI then creates seamless block flow diagrams up to precise layouts of the system units and connections. In addition, the AI can predict plant-specific key figures such as possible power consumption, heat generation and a comprehensive list of the most important components. The data generated in this way represents the basic concept of a plant. It can then be transferred to engineering and simulation software such as Siemens' Comos and gProms, for example, to automatically create the piping and instrumentation diagrams.

"Green H₂ is crucial for the decarbonization of industry. It will be a scarce commodity for the foreseeable future. This makes it even more important to accelerate the ramp-up of production capacities,” said Axel Lorenz, CEO Process Automation at Siemens. “Generative artificial intelligence can provide support in the crucial phases of H₂ production to save considerable time and costs. With the H₂ plant configurator, it is easier than ever to plan and operate a more sustainable H₂ plant and thus lay the foundation for efficient production.”

Faster engineering with Comos AI. Siemens is also launching an AI-based tool for the project planning phase of H₂ plants. The Comos AI engineering assistant can create equipment specifications and diagrams based on natural language descriptions and automatically completes or corrects models and drawings. The assistant can also provide support during cross-domain phases in engineering or cross-product workflows by converting models, drawings, and information structures, for example for simulation software such as Simit from Siemens. In addition, users can use Comos AI to retrieve information from engineering-relevant products – via their own prompt or suggested by the assistant. In this way, the assistant provides answers to documentation, specifications, or technical details. By entering images, scans, or PDFs, it can also proactively deliver relevant resources and transform them into precise diagrams and models.

AI upgrade for the distributed control system. To simplify the automation of processes in H₂ plants, Siemens is launching an innovative module for the Simatic PCS neo distributed control system: SFC Generation. The module is integrated into the process control system and can create so-called sequential function charts (SFCs) using generative artificial intelligence. These charts provide a visual representation of process logic and allow users to easily manage complex workflows. This is possible based on specific prompts or by copying a prose process description into the module's chat window.
