Hystar Pitch Deck: All 20 Slides + Teardown

Hystar Series B Teardown: Engineering Credibility Over Marketing Hype

Hystar’s Series B pitch deck, used to raise $26M in 2023, is a distinct departure from the high-gloss, narrative-heavy decks typical of Silicon Valley software startups. As a Norwegian hardware company in the green hydrogen space, Hystar leans heavily into technical validation, infrastructure, and modular engineering. The deck serves as a progress report for Series A investors and a feasibility study for new Series B participants, proving that their PEM (Proton Exchange Membrane) electrolyzer technology is not just a lab concept, but a scalable industrial product.

Slide 1-3: Identity and Values

The deck opens with a minimalist title slide featuring the company logo and a date of January 4, 2023. Slide 2 provides a concise 'What we do' statement: 'Hystar specializes in ultra-efficient PEM electrolysers for the production of green hydrogen from water electrolysis.' This is a textbook example of a clear value proposition. It identifies the technology (PEM), the benefit (ultra-efficient), and the market (green hydrogen).

Slide 3 outlines the company values: Honesty, Innovation, Passion, and Ambition. While values slides are often considered filler, Hystar uses this to set the tone for the technical data to follow, specifically highlighting 'Honesty' as being 'open about what we can achieve' and giving 'candid feedback.' In the capital-intensive world of hydrogen, where overpromising is common, this emphasis on realistic reporting is a strategic choice to build investor trust.

Slide 4: The Technical De-risking Slide

This is arguably the most important slide in the deck for a Series B round. It details a 2020 short-stack test that ran for 4,000 hours. For hardware investors, durability is the primary concern. Hystar presents three specific metrics: a current density target of 3 A/cm2 at 1.9 V, degradation at less than 10μV/h, and low hydrogen crossover. By showing polarization curves and durability graphs, Hystar moves the conversation from 'if' the technology works to 'how well' it performs. The mention that tests were based on an 'off-the-shelf' stack platform suggests they aren't reinventing the wheel where they don't have to, which reduces execution risk.

Slide 5: Product Differentiation (Vega, Mira, Orion)

Slide 5 introduces Hystar’s product lineup, categorized by performance goals. They offer 'Vega' for efficiency (claiming a >10% decrease in energy consumption) and 'Mira' for high output (claiming a >150% increase in production rates). The inclusion of a polarization curve graph comparing Hystar to 'State of the art PEM electrolysers' provides a visual benchmark for their competitive advantage. This slide effectively communicates that Hystar has a versatile platform capable of meeting different customer needs—whether the customer prioritizes low operational costs (efficiency) or low capital expenditure (high output).

Slide 6-7: The Path to Gigawatt Scale

Scaling is the central theme of slides 6 and 7. Slide 6 illustrates the modularity of the design, showing the progression from a 0.7 MW stack to a 2 MW module, then to containerized solutions (2-50 MW), and finally to large plants (10 MW to 1 GW). This 'Lego-block' approach to engineering is highly attractive to investors because it simplifies manufacturing and deployment.

Slide 7 dives deeper into 'Orion,' their solution for 100 MW+ installations. It explains that 10 modules of 2 MW each form a 20 MW cluster with a shared 'Balance of Plant' (water treatment, cooling, and purification). By sharing these auxiliary systems across multiple stacks, Hystar demonstrates a clear path to reducing the total cost of ownership for large-scale industrial customers.

Slide 8-9: Infrastructure and Supply Chain

Slide 8 moves from theory to physical reality. It shows the Hystar facilities in Høvik, Norway, including HQ, R&D, and a 'GW automated production facility.' Including photos of the actual office and an aerial view of the site proves that the company has the physical capacity to execute its plans. This is a crucial 'proof of life' for a Series B hardware company.

Slide 9 outlines the production strategy. Hystar isn't trying to build every nut and bolt. They use 'proven suppliers' for components and focus their in-house efforts on 'Automized high-volume' stack assembly. The final step—system assembly—is handled through partnerships with system integrators and EPCs (Engineering, Procurement, and Construction firms). This asset-light approach to the final assembly stage suggests a scalable business model that won't require Hystar to become a massive construction company itself.

Slide 10: Traction and Achievements

The final slide in this set summarizes key achievements since the last funding round. It lists the successful test of the new stack design, the signing of the first customer demo project, the completion of the core team, and the securing of facilities and supply chain. This slide serves as a 'promises made, promises kept' summary, showing that the team has hit its previous milestones and is ready for the next phase of growth funded by the Series B.

What Works in Hystar's Deck

Technical Rigor: The deck does not shy away from engineering data. By including polarization curves and specific degradation rates (Slide 4), Hystar speaks directly to the technical due diligence teams that lead Series B rounds in the energy sector. This builds immediate credibility that a marketing-heavy deck would lack.

Modular Logic: The visual representation of scaling from 0.7 MW to 1 GW (Slide 6) is exceptionally clear. It tells a story of a technology that is ready for small-scale pilots today but is architected for the massive utility-scale projects of tomorrow. This addresses both short-term revenue and long-term market dominance.

Physical Proof: Showing the actual production facility and R&D center (Slide 8) is vital for hardware. It eliminates the 'vaporware' risk and shows that the company has already invested in the infrastructure necessary to scale.

What is Missing from Hystar's Deck

Detailed Team Slide: While the publisher summary mentions the company is Norwegian and Slide 10 notes the 'Core team is in place,' the provided slides do not feature a dedicated team slide highlighting the founders' backgrounds or previous exits. In a Series B, investors want to see the specific expertise of the leadership team in scaling industrial manufacturing.

Financial Projections and Unit Economics: There is no mention of the cost per kilogram of hydrogen produced or the projected revenue growth over the next 3-5 years. While the technical efficiency gains are clear, the translation of those gains into a profitable business model is left out of these slides.

Competitive Landscape: Slide 5 mentions 'State of the art PEM electrolysers' as a benchmark, but it does not name specific competitors or explain how Hystar will defend its position against established giants or other well-funded startups in the hydrogen space.

Lessons for Founders

Lead with Data, Not Adjectives: Hystar doesn't just say their electrolyzers are 'better'; they say they have a '>10% decrease in energy consumption' (Slide 5). Founders in technical fields should always quantify their advantages with specific, verifiable metrics.

Show the 'How,' Not Just the 'What': Many decks focus on the final product. Hystar spends significant time on the production process and supply chain (Slide 9). For Series B and beyond, investors are buying into your ability to manufacture and deliver at scale, not just your ability to build a prototype.

Use Modular Architecture to De-risk Scaling: If your product needs to reach massive scale to be viable, show a step-by-step path to get there. Hystar’s progression from stack to module to cluster (Slide 6-7) makes a 1 GW plant feel like a series of manageable engineering tasks rather than an impossible leap.
