Water, membrane & electrochemical technology advisory

From promising prototype to proven technology.

Independent technical assessment and hands-on development support to evaluate performance, reduce scale-up risk and build a credible business case.

Technology readiness level (TRL)

From experimental proof of concept to complete, qualified systems: we clarify what has been demonstrated, what remains uncertain and what evidence is needed before the next investment.

The founder’s track record

20+

years developing water and energy technology

11

granted patents as inventor, from 14 patent families in membrane and electrochemical processes

3

technologies commercialised, from research to market

5+

years as Head of Technology and CTO, Berghof Membranes

Selected experience

Experience gained across doctoral research and technology leadership roles, spanning membrane development, process engineering and commercialisation.

Reverse electrodialysis

Osmotic energy

Context

Wetsus and University of Twente · Doctoral researcher · 2005–⁠2009

Personal contribution

Identified how membranes, spacers and ion transport limit power output, and invented an ion‑conductive spacer.

Outcome

PhD thesis (2009) and granted patent EP2405994B1, now held by REDstack, which later took RED to pilot scale with partners.

Capacitive deionisation

Water treatment

Context

Voltea · R&D Manager, then Technology Manager · 2009–⁠2017 · Netherlands and USA

Personal contribution

Managed R&D and technology development during Voltea’s growth phase, and introduced in‑house IP management processes.

Outcome

Named inventor in several Voltea patent families, including granted US patents, as Voltea expanded in European and US markets.

Tubular membranes and systems

Separation and forward osmosis

Context

Berghof Membranes · Head of Technology and CTO · 2017–⁠2022 · Executive leadership team

Personal contribution

Led a team of about ten, plus external contractors, developing second‑generation structured tubular membranes and specialised tubular forward‑osmosis membranes.

Outcome

Named inventor in Berghof patent families on structured tubular membranes and tubular forward‑osmosis membranes.

The questions clients bring to us

Investors and acquirers

An independent technical view before you commit capital.

Is this start-up’s energy claim credible at full scale?

Does this pilot actually test the claim it is meant to prove?

Technical due diligence →

Technology companies

Senior technical leadership and engineering support without a full-time hire.

What should our R&D team build next, and what should it stop?

What will it take to move from pilot to a first commercial plant?

CTO advisory →

Industrial operators and utilities

Clear numbers before you choose a process, supplier or brine strategy.

What will this plant really cost per cubic metre of water?

Can our brine become a revenue stream instead of a disposal cost?

Which membrane process fits our water, and who can supply it?

Techno-economic evaluation →

Four ways to work with us

Every engagement starts with an agreed scope, deliverable and fee.

Technical due diligence

When

Before you invest in, acquire or license a technology.

Decision

Whether to proceed, and on what conditions.

Technology readiness
Performance claims
Scale-up risk

Cost position

Technical differentiation
Team capability

Written report with findings, red flags and a clear recommendation

Fixed scope and fee

Techno-economic evaluation and business case

When

Before you commit capital to a process, plant or product.

Decision

Whether the economics justify the next investment step.

CAPEX and OPEX
Energy use
Cost of water (USD/m³)
By-product revenue
NPV, IRR and payback

Auditable financial model and business case for your board or investors

Fixed scope and fee

Membrane and process engineering

When

From early proof of concept through laboratory validation, pilot development and full‑scale implementation.

Decision

Which process, membrane and test plan to commit to.

Proof-of-concept assessment and experimental design

Process design
Membrane selection
Pilot reviews

Test protocols

Scale-up

Design reviews, test plans and engineering recommendations

Project-based or day rate

CTO advisory

When

You need senior technical guidance without a full‑time hire.

Decision

What to develop next, what to stop and how to resource it.

Technology roadmap

R&D management
Technology and IP strategy
Hiring
Board support

A prioritised technology roadmap, development milestones and regular decision reviews, as agreed in scope

Monthly retainer

IP work covers technical differentiation and technology strategy; it is not a legal patent opinion. Cost estimates and business cases support investment decisions; they do not guarantee outcomes.

Client experience
