The 'Ultra-Orphan' Approach to Decarbonization: Targeting Niche Industrial Problems for Breakthrough Gains
Why Precision ‘Therapy’ Also Matters in Decarbonization
What if the biggest climate wins are hiding where no one is looking?
In medicine, gene therapy has been quietly achieving breakthroughs by targeting ultra-rare, devastating diseases. For example, researchers have recently used gene editing to fix mutations causing Tay-Sachs disease in mice. It’s not just a technical feat, it’s a lesson in the power of precision.
Now, let’s map that mindset onto climate innovation. The industrial sector, especially hard-to-abate sectors like cement and steel, presents significant challenges and opportunities for climate tech and industrial decarbonization. Just two sectors, cement and steel, account for around 13.5% of global CO2 emissions. Yet, these areas are often sidestepped by mainstream decarbonization efforts. Why? Because the challenges are knotty, the potential gains seem small, and the solutions rarely fit tidy, one-size-fits-all models.
As practitioners, we’ve seen how conventional approaches miss the mark in heavy industry. Too often, startups chase the obvious, while deep tech innovators tackling granular, niche problems get overlooked. But what if, by embracing an “ultra-orphan” approach, zeroing in on these overlooked, high-impact challenges, we could unlock breakthrough gains for both the climate and the bottom line?
Of course, not every niche problem is worth solving. Careful selection is key. But if you’re wrestling with the tension between financial value creation and real sustainability, you might find your answer in the places most people ignore.
Learning from Gene Therapy: Why 'Ultra-Orphan' Targeting Works
The Ultra-Orphan Disease Model
Ultra-orphan diseases affect tiny patient populations. Developing a therapy is tough, expensive, and risky. Yet, when it works, the results are transformative. Take GEMMABio’s recent launch to develop therapies for ultra-orphan diseases. Even in a sector beset by setbacks, there’s fierce belief in the potential of precision innovation.
We often ask: what if climate innovation took a page from biotech’s playbook? Just as a faulty gene can cause outsized problems, a single emissions source, say, a unique chemical process or a specific kiln design, can undermine whole decarbonization strategies. Gene editing corrects the root cause. Why not do the same for industrial emissions? This analogy highlights how targeted interventions can yield outsize results, especially when the broader system depends on the fidelity of a single process.
Precision in Climate Innovation
Precision is about impact per effort. In gene therapy, it means correcting a specific mutation. In climate innovation, it’s about deploying deep tech, carbon capture, or AI exactly where it’s needed, tailoring solutions for a niche, hard-to-abate process.
This “ultra-orphan” lens reframes niche emissions problems as climate orphans: neglected, difficult, but with the potential for disproportionate impact if solved. And there’s a bonus, solutions in these spaces are often defensible and hard to copy, offering a real competitive advantage. Of course, biotech and climate tech are different worlds; regulatory and market realities don’t always map one-to-one. Still, the lesson holds: precision beats scattershot approaches, especially when resources are limited. The more precisely you align a solution with a unique problem, the greater your chance of both commercial and climate success.
The Case for Targeting Niche, Hard-to-Abate Sectors in Climate Tech Innovation
Where Mainstream Approaches Fall Short
Mainstream decarbonization often focuses on easy wins: renewable power, electric vehicles, energy efficiency in homes. These are essential, but they leave stubborn gaps. Many emissions-intensive niches, specialty chemicals, certain construction materials, advanced manufacturing processes, are left behind because they’re perceived as too small or too difficult. This oversight means some of the world’s most persistent sources of industrial emissions remain unsolved, quietly adding up to a significant climate burden.
Defining and Identifying “Ultra-Orphan” Problems
Ultra-orphan problems are those that, while representing a small market or unique technical challenge, cause outsized emissions or costs if left unsolved. Think of a plant with a unique process, a rare industrial solvent, or a chemical used in only a handful of factories worldwide.
Hydrogen-based steel production: Startups are reengineering steelmaking with hydrogen to dramatically reduce emissions. This has now moved out of the lab and it’s already making headway in niche, high-value applications.
Alternative cements: By developing new chemistries, innovators are cutting CO2 from one of the world’s dirtiest processes, often for specialty, high-performance uses.
Carbon Capture and Utilization (CCU) in specialty chemicals: Small in scale still, but these projects convert CO2 into valuable products, proving that targeted climate tech can deliver both environmental and commercial returns.
The Impact Multiplier in Niche Markets
However, when the right ultra-orphan challenge is solved, the impact is multiplied. In the UK, for instance, green buildings built to poor standards have cost owners £5 billion extra over seven years. That’s the hidden cost of ignoring tailored, integrated solutions in favor of generic fixes.
For example, in the MENA region, certain desalination processes emit substantial CO2 but are rarely prioritized for decarbonization solutions, targeting such overlooked processes can yield both regional and global climate impact. This type of focused innovation can create ripple effects, inspiring adjacent industries to adopt similar approaches and amplifying the original investment in innovation.
At Nexus Climate, we’ve seen firsthand how even small pilot programs in overlooked sectors can open doors to new markets and partners, sometimes sparking ripple effects across industries. Are you working on a niche decarbonization challenge? Here's why tackling these challenges could unlock real value for both climate impact and your business.
Selecting the right niche is crucial - seek opportunities that are often overlooked but significant enough to drive meaningful climate and business impact.
Overcoming Barriers: Financing, Policy, and Innovation in Hard-to-Abate Sectors
The Funding Gap for Hard-to-Abate Solutions
Securing funding for ultra-orphan decarbonization solutions is challenging, but actionable strategies exist to overcome these hurdles. Investors often shy away from niche solutions, worried about unclear market signals and scaling risk. Meanwhile, many climate tech startups are overvalued without delivering real impact. This gap between hype and substance means that genuinely transformative ideas can struggle to get the resources they need. As a result, pragmatic evidence of both climate and commercial impact becomes the differentiator for attracting capital.
Policy Levers and Ecosystem Enablers
Policy can be the difference between stalling out and scaling up. Tailored policy incentives, such as targeted grants for industrial pilots or accelerated permitting for deep tech solutions in heavy industry, have proven effective in catalyzing progress where generic policies fall short. Regulatory frameworks that support innovation, by rewarding emissions reductions, creating procurement pathways, or de-risking new tech, can accelerate the adoption of ultra-orphan solutions. At Nexus Climate, our policy advisory work is dedicated to creating a more favorable environment for early-stage innovation and investment. Understanding the policy landscape and anticipating regulatory shifts can also help innovators get ahead of the curve and de-risk their pathways to scale.
Internal Innovation: The Role of AI and Collaboration
Innovation isn’t just about the product or concept, it’s about how you build, test, and scale. Internal innovation, especially using AI and machine learning, is fast becoming a defining edge for climate tech startups, particularly in MENA and Europe. By leveraging these tools, teams can iterate faster and adapt their solutions to the unique needs of ultra-orphan sectors. Leveraging generative AI for rapid process optimization or predictive maintenance in industrial equipment has enabled several climate tech startups to reduce operational emissions faster and more cost-effectively. We advise clients to focus on the right ecosystem partners and to build internal innovation capabilities early. Collaborative approaches, not just within the company but across sectors, often reveal unexpected synergies and accelerate breakthroughs.
Struggling to attract funding for your niche tech? You’re not alone, and there are ways forward. Here’s a quick checklist:
Validate your climate and commercial impact with real data
Engage with policy advocates early
Invest in internal innovation (AI, ML, agile methods)
Find practitioner-led communities to collaborate and share insights
Yes, the road is tough. Policy and market dynamics don’t always reward the most impactful solutions. But the right partnerships and innovation mindset can tip the odds in your favor. When you can clearly demonstrate how your solution addresses a well-defined gap, even niche innovations can gain traction and scale.
