Developing bankable water and biomass infrastructure.

ACEX structures projects that turn produced water and agricultural residues into long-horizon industrial assets. We secure feedstock, integrate proven engineering, and design capital stacks that can attract institutional partners.

Ventures.

Two asset classes. One disciplined development model.

ACEX develops Water and Biomass-to-Carbon projects where industrial fundamentals can be secured early. We prioritize feedstock certainty, proven engineering, and long-horizon capital stacks. Each venture advances only when the path to bankability is clear.

Water Treatment

ACEX develops produced water treatment and desalination assets for industrial environments. We treat produced water as a recoverable resource and prioritize projects with defined supply, clear permitting pathways, and anchored industrial demand.Our approach integrates proven engineering partners with robust commercial structures that support reliable operations and predictable cost profiles. Projects progress only when feedstock terms, technical performance assumptions, and reuse or discharge pathways align with a long-horizon investment case.

Development focus

  • Produced water treatment for oil & gas and industrial basins

  • Reuse, agricultural supply, or compliant discharge pathways

  • Long-term supply and operational reliability

Biomass to Carbon

ACEX develops biomass-to-carbon projects that convert agricultural residues into stable carbon products, including biochar. Where durability can be verified, carbon revenue provides an additional stream. We prioritize high-volume residue streams and secure supply before technology selection and financial structuring.Our model integrates proven thermochemical processes with commercially realistic routes to market, balancing local agricultural demand for biochar with high-quality carbon removal criteria. Projects are advanced only when feedstock aggregation, operating assumptions, and verification logic can be aligned into a disciplined capital stack.

Development focus

  • Agricultural residues with scalable, contracted supply

  • Biochar for soil/industrial use + durability-aligned CDR

  • Structured offtake and verification pathways

Approach.

From resource stream to bankable asset.

ACEX advances projects only when fundamentals can be structured into a long-horizon asset. We secure feedstock and demand, match them with proven engineering, and design capital stacks, including concessional or carbon finance where justified, so assets can withstand technical scrutiny and attract institutional partners.

Development focus

We prioritize residues and produced water streams where volume, quality, and logistics can be contracted early. Without highly certain supply conditions, we do not advance development.

Proven engineering integration

We work with technologies that have operating reference plants and defined performance envelopes. Integration is adapted to local constraints, while core process risk is minimized from the outset.

Capital stack design

We structure projects around long-term industrial offtake and realistic operating assumptions, layering equity, debt and, where justified, carbon or concessional finance to improve resilience while preserving economics.

About.

From resource stream to bankable asset.

ACEX is a sustainable infrastructure developer headquartered in Denmark. We structure water and biomass projects into long-horizon assets by aligning feedstock security, proven engineering, and disciplined capital stacks. The firm is independent, founder-led, and works with a limited number of industrial and financial partners who share a long-term view on asset performance.

ACEX in Brief

Independent developer headquartered in Copenhagen, Denmark.


Focused on produced water treatment and biomass-to-carbon projects.


Acts as principal developer and project integrator, not an advisory shop.


Holds projects in dedicated SPVs with local operators and capital partners.

How we Partner

We engage at early structuring, before key assumptions are locked.


Leads de-risking and capital stack; partners run operations and permitting.


We work with a focused group of industrial off-takers and long-term capital partners.


Aligns economics via fees and, where relevant, SPV equity.
