Who is PhaseTree and what do they do?

Copenhagen based startup, PhaseTree, was founded in 2021 as a spin off from the Technical University of Denmark (DTU). Their mission is to reinvent the material discovery process, using a unique combination of computer simulations, lab automation, and artificial intelligence (AI) to drastically shorten the time it takes to find and develop new materials.

Slow, up until now

At the moment, creating new materials for clean energy technologies is an incredibly slow and expensive process. The current industry norm is for this to take up to 20 years due to time consuming lab testing and trial and error experiments. However, PhaseTree’s solution, based on advanced multi scale modelling techniques, reduces this to just two years, thereby transforming the way sustainable materials are discovered.

Could help the move away from fossil fuels

This speed up could have major implications for mostly clean energy technology industries that rely on scarce or expensive raw materials, such as the battery, automobile, and steel sectors. By identifying alternative materials that are cheaper, more sustainable, and easier to produce, PhaseTree aims to help companies move away from their reliance on rare earth metals and fossil fuels.

How does PhaseTree’s technology work?

Unlike many AI driven material discovery tools that rely purely on data correlations, PhaseTree takes a different approach:. a “physics first, AI on top” approach. Their platform starts with well established scientific principles, then layers AI on top to refine predictions. This ensures that the materials they identify are not only promising on paper but actually viable in the real world.

PhaseTree’s three pronged approach includes:

• Physics based modelling. This involves analysing fundamental material properties like composition, atomic structure, defects and microstructures.
• AI refinement. Once strong candidates are identified using scientific principles, AI is applied to optimise their properties and manufacturing potential.
• Lab automation. Cutting down on manual testing time by integrating automated lab experiments that validate material performance faster than traditional methods.

As Jin Hyun Chang, co-founder and CTO of PhaseTree, explains: “Our approach accelerates discovery by combining physics-based modelling with AI, allowing us to rapidly identify and refine promising candidates that would traditionally take decades to develop.”

This “physics first, AI on top” method is what makes PhaseTree stand out in an increasingly crowded sector. In 2024 alone, AI powered material discovery startups raised over $260 million, with ten out of 17 funding rounds going to European companies, including ExoMatter, Dunia, and Orbital. However, while many of these companies depend heavily on AI driven correlations, PhaseTree tries to focus more on real world scientific accuracy.

Why PhaseTree’s work could be more important than ever

The race to discover new materials is not just about efficiency and innovation. It’s about economic and environmental survival. Therefore, some of the key reasons why PhaseTree’s work could be of particular importance now include:

• The rare earth crisis. With China controlling the majority of the rare earth supply chain, industries are facing soaring costs, limited access, and increasing geopolitical risks.
• Environmental impact. Many existing materials, such as those used in lithium ion batteries and steel production, have significant environmental drawbacks, including heavy reliance on fossil fuels and high CO₂ emissions.
• Manufacturing challenges. A material may work in a research lab, but that doesn’t mean it can be produced at scale.

PhaseTree’s CEO, Amit Luthra, has highlighted how its work directly addresses these challenges, saying: “From the outset, we design materials with manufacturability in mind, ensuring they can be synthesised at scale rather than remaining a theoretical concept or lab-scale prototype.”

Also, as Christian Lindegaard Jepsen, Partner at Heartcore Capital, a source of PhaseTree’s funding, explains: “Materials play a crucial role in developing clean energy and sustainable technologies. PhaseTree makes it easier and faster to find better alternatives that can help reduce environmental impact and improve efficiency.”

By focusing on low cost, abundant materials with straightforward synthesis routes, PhaseTree is hoping to maximise the likelihood of real world adoption by major industrial players.

€3 million funding to drive expansion

To take their work to the next level, PhaseTree has just secured €3 million from Denmark based venture capital firm Heartcore Capital. It’s understood that this funding will be used to:

• Expand R&D efforts, enhancing their material discovery platform.
• Grow the PhaseTree team, bringing in more scientists, engineers and AI specialists.
• Scale up collaborations with some of the world’s largest battery, automotive and steel manufacturers.

What this could mean for the future

If PhaseTree succeeds in scaling up its technology, it could change the way industries develop materials for the better by reducing their dependence on scarce, expensive and environmentally damaging resources.

Some of the potential impacts include:

• Cheaper, more efficient batteries that rely on readily available materials rather than rare earth metals.
• Stronger, lighter alloys for the automotive and aerospace industries, reducing fuel consumption and emissions.
• Faster breakthroughs in renewable energy technology, making solar panels and wind turbines more efficient and cost effective.

With the clean energy sector desperate for innovation, and supply chain disruptions making material discovery more urgent than ever, PhaseTree may well be in the right place at the right time.

What does this mean for your organisation?

By combining the accuracy of scientific modelling with the speed and efficiency of AI, they are setting a precedent for how next generation materials can be developed. The fact that PhaseTree’s approach can significantly reduce development timelines and costs could reshape entire supply chains. This could make sustainable materials more accessible for businesses that have historically struggled with long and expensive R&D cycles. With global demand for cleaner, more efficient materials growing rapidly, this innovation could arrive at a crucial turning point for industries that are under mounting pressure to reduce their environmental impact.

For UK businesses, this development could open up significant opportunities. For example, as industries face increasing regulation on carbon emissions and sustainability, the ability to source materials that are not only greener but also cost effective, could provide a real competitive advantage. British manufacturers, particularly in sectors such as automotive, aerospace and energy, could benefit from greater access to advanced materials that reduce reliance on imports and offer more stable supply chains. With the UK aiming to become a leader in green technology and advanced manufacturing, partnerships with companies like PhaseTree could support efforts to drive innovation domestically while reducing exposure to global market volatility.

Beyond the business world, the impact of faster, more sustainable material discovery could help society as a whole. For example, the widespread availability of new, more efficient materials could lower the cost of renewable energy infrastructure, making technologies like solar power and wind energy more affordable for consumers. Also, the battery industry, which is crucial to the success of electric vehicles and energy storage, could see faster progress towards alternatives that reduce reliance on scarce or ethically problematic resources. In turn, this could help accelerate the transition to low carbon transport and cleaner energy grids, benefiting both the environment and consumers.

That said, while PhaseTree’s approach is promising, it remains to be seen how quickly industries can actually integrate these materials into large scale production. The challenge isn’t only about discovery but also ensuring that new materials can be manufactured at scale, meet regulatory requirements, and gain industry wide adoption. Although PhaseTree’s focus on manufacturability from the outset is a positive step, real world implementation will be the true test of its success.
