The new way of working with Power-to-X

Plan smarter, collaborate better, and get bankable faster.

A complete workspace to align your team

Use Southern Lights to

Start with high-level inputs like location, business model, and technology choices, and build a structured project you can evolve over time.

As your data improves, refine the inputs without losing clarity. Our platform helps you avoid unnecessary complexity early on while still supporting detailed outputs later. Everything is versioned, structured, and ready to scale as your project matures.

Every project follows a standardized structure covering technical setup, cost data, and output profiles. This means your whole team works in sync with a clear overview of what’s been done, what’s changed, and what’s next.

Whether preparing for handoff to engineering or financing, or simply sharing progress internally, everything is organized, auditable, and easy to understand.

Your project is a living asset. As new inputs become available, like updated load profiles, improved CAPEX data, or fresh business insights, you can easily update assumptions and compare scenarios.

Understand the risks, optimize for performance, and keep your team moving in the right direction. With every iteration, you gain confidence and control.

Generate consistent, transparent reports that turn complex project data into clear reports.

Whether presenting to a board, seeking investor buy-in, or aligning internal teams, our platform gives you the tools to communicate your project’s KPI’s with credibility.

Everything is traceable and backed by real data, so decision-makers can move forward faster.

The Southern Lights software provides an intuitive and user-friendly platform for quickly gaining an overview of PtX scenarios focused on hydrogen and e-fuel production.

For deeper analysis, detailed insights are available, and the support team is both responsive and solution-oriented. Development of the software is carried out in close and pragmatic collaboration, ensuring the tool meets our needs.

Everything you need in one platform

Build and simulate projects that reflect real-world conditions

Let your project come to life. Define key parameters like power supply, electrolyzer setup, cost structure, and financing. Upload your own profiles or use defaults, everything feeds into a high-resolution simulation based on our powerful energy models.

Upload and combine solar, wind, and grid profiles to define your energy mix
Select electrolyzer technologies from our built-in catalog and configure how they operate
Add key system components like storage, compression, and downstream conversion (e.g. ammonia and methane)
Simulate performance, costs, and LCOH with real hourly behavior and degradation

Find the best system configuration

Our built-in optimization engine helps you determine the ideal size and configuration of your system to maximize profitability. No need to define components manually, just set your goals and constraints and let the software guide you.

Compare projects side-by-side

When you’re deciding between different configurations, the comparison feature makes it easy. Duplicate your design, tweak parameters, and compare results side-by-side in a clear, visual layout.

Create reports that build conviction

Our reporting tools make it easy to present your project in a way that builds conviction. Automatically generate clean, shareable reports that include inputs, assumptions, and outputs.
