The Strategic Vision: Where Hydrogen Meets Water

AP Ventures stands at the forefront of a transformative convergence between hydrogen technologies and water innovation. Their £500M Fund III represents a strategic recognition that these two sectors are inextricably linked in the push toward industrial decarbonization.
The fund’s thesis centers on the understanding that hydrogen production requires substantial water resources, while water treatment and management increasingly demand energy-efficient solutions that hydrogen can provide. This symbiotic relationship forms the cornerstone of AP Ventures’ investment strategy.
Their approach targets technologies that bridge these sectors in novel ways. For instance, they prioritize investments in electrolysis innovations that improve water efficiency in green hydrogen production. Simultaneously, they back solutions that leverage hydrogen’s potential in wastewater treatment processes, particularly in energy-intensive industrial applications.
What sets AP Ventures apart is their holistic view of the industrial ecosystem. Rather than treating hydrogen and water as separate investment verticals, they identify opportunities where advancements in one area catalyze improvements in the other. This methodology has proven particularly valuable in addressing the water-energy nexus challenges faced by heavy industries.
The fund’s strategic focus extends to three key areas: decarbonization technologies that optimize water usage, water treatment solutions that enable more efficient hydrogen production, and circular economy approaches that maximize resource recovery. This creates a multiplier effect where improvements in one domain cascade through the entire industrial system.
Critically, AP Ventures recognizes that the transition to a hydrogen economy cannot succeed without solving associated water challenges. Their investments reflect this reality, supporting technologies that address both the water intensity of hydrogen production and the energy intensity of water treatment.
This strategic alignment with both sectors positions AP Ventures to capitalize on the growing industrial demand for sustainable solutions while addressing critical environmental challenges. Their approach exemplifies how strategic investment can drive innovation at the intersection of crucial resource management challenges.
As discussed in Is Hydrogen More of a Water Sector Miracle or a World’s Decarbonization Problem?, this dual focus on hydrogen and water technologies represents a crucial evolution in how we approach industrial sustainability, creating a blueprint for future investment in clean technology solutions.
Portfolio Power: From Lab to Market

AP Ventures’ distinctive investment methodology combines deep technical expertise with hands-on portfolio support. Their ticket sizes typically range from £1-10 million for early-stage companies, scaling up to £20+ million for growth-stage opportunities. This flexible capital deployment allows them to support ventures through multiple funding rounds as companies mature.
What sets AP Ventures apart is their highly engaged investment approach. The firm takes active board positions in nearly all portfolio companies, providing strategic guidance beyond just capital. Their team of technical experts and industry veterans work closely with management teams to accelerate commercialization efforts, forge strategic partnerships, and navigate scale-up challenges.
This hands-on philosophy stems from AP Ventures’ deep understanding that breakthrough technologies in hydrogen and water sectors face unique hurdles in moving from lab to market. The team leverages their extensive network of industrial partners and customers to create commercial opportunities and validation pathways for portfolio companies. They also facilitate technology collaboration between portfolio companies where synergies exist.
A key focus is helping portfolio companies build robust business models that can attract follow-on capital. AP Ventures often leads investment rounds but also excels at bringing in strategic co-investors who can add further value. Their portfolio support includes assistance with business development, recruitment of key personnel, and guidance on intellectual property strategy.
The firm maintains a balanced portfolio across technology readiness levels – from early-stage breakthrough innovations to later-stage companies with proven commercial traction. This diversification allows them to manage risk while maintaining exposure to potentially transformative technologies. They are particularly drawn to solutions that can scale globally and create meaningful environmental impact.
Integrating environmental, social and governance (ESG) considerations is central to AP Ventures’ investment process. Beyond financial returns, they measure success through metrics like carbon emissions avoided, water saved or purified, and jobs created. This dual focus on commercial success and positive impact has helped establish AP Ventures as a trusted partner for entrepreneurs tackling critical sustainability challenges.
The Water Technology Thesis

AP Ventures’ approach to water technology investment reflects a deep understanding of the sector’s critical role in industrial decarbonization and sustainable development. Their thesis centers on breakthrough technologies that can dramatically improve water treatment efficiency while reducing energy consumption and environmental impact.
The fund prioritizes three key areas within water technology. First, they target advanced purification solutions that can handle complex industrial wastewater streams, particularly those from mining, oil & gas, and manufacturing sectors. Their interest extends to technologies that can selectively remove high-value materials like lithium and rare earth elements during the treatment process.
Second, AP Ventures focuses heavily on water treatment innovations that align with their hydrogen expertise. This includes technologies for producing ultra-pure water needed in green hydrogen production, as well as solutions that can handle the unique wastewater challenges of hydrogen facilities. This strategic alignment between their water and hydrogen portfolios creates valuable synergies for both sectors.
Their third area of focus is resource recovery and circular economy solutions. They actively seek technologies that can transform wastewater treatment from a cost center into a value generator through the recovery of energy, nutrients, and valuable materials. This includes innovations in biogas production, phosphorus recovery, and the conversion of treatment byproducts into valuable commodities.
When evaluating potential investments, AP Ventures applies rigorous criteria. Technologies must demonstrate clear competitive advantages in either treatment efficiency, energy consumption, or operational costs. The fund favors solutions that can scale rapidly and have potential applications across multiple industries. They particularly value innovations that can help industrial customers meet increasingly stringent environmental regulations while improving their bottom line.
Markedly, AP Ventures takes a long-term view on water technology investments, recognizing that development cycles in this sector often require patient capital. They typically invest in post-prototype technologies that have demonstrated technical feasibility and are ready for commercial scale-up. Their sweet spot lies in solutions that can deliver both environmental benefits and compelling financial returns.
The fund’s investment strategy reflects a sophisticated understanding that water challenges are intrinsically linked to energy, climate, and industrial productivity. This holistic perspective shapes their portfolio construction and helps them identify technologies that can deliver outsized impact across multiple dimensions.
