About

Who I Am

I am an energy infrastructure strategist with over two decades of practical experience across distributed generation, combined heat and power (CHP), biogas, microgrids, and resilient power systems. My entire career has been spent in onsite power generation and infrastructure deployment. This vantage point that gives me a grounded understanding of both the engineering realities and the commercial hurdles behind major projects.

Over the years, I’ve worked on projects across vastly different grid environments, cultures, and regulatory regimes, notably across Europe, North America, Africa, South Asia, and Australasia. My goal is simple: turn complex energy and environmental technologies into practical, measurable infrastructure and explain them in understandable logical terms.

As a senior executive at Clarke Energy, I’ve watched the data center power landscape undergo a huge shift. A decade ago, onsite baseload generation was considered an edge case for outlier projects; the grid was assumed to be reliable and ready. Today, power availability is the defining constraint of digital infrastructure.

I recently wrote Five Nines and Fast Power to help investors, operators, and developers make sense of this shift and navigate high-stakes energy decisions.

Infrastructure isn't just a collection of physical assets, it is a dynamic system that must continuously evolve alongside technology, economics, regulation, and society.

What I Focus On

The central question I keep returning to is this:

How do you build power infrastructure that is reliable from day one, commercially viable for over a decade, clear in its decarbonization pathway, and flexible enough to adapt as energy markets shift?

That challenge remains identical whether you're powering a manufacturing campus in Nigeria, a biogas plant handling municipal waste in India, or a hyperscale data center navigating severe grid queues in the United States. While local economics and grid carbon intensities vary, the core infrastructure puzzle is the same.

My work centers on distributed energy systems, hybrid architectures, CHP, and resilient design for facilities that simply cannot afford an outage. Right now, my primary focus is at the intersection of AI-driven data center demand, grid capacity bottlenecks, and the critical role behind-the-meter generation plays in bridging speed-to-power with long-term net-zero goals.

How I Got Here

My path into energy was anything but linear. With a postgraduate background in environmental technology, my early career involved commercializing water treatment and novel waste management technologies.

Those early startup attempts taught me a fundamental lesson: the gap between a working innovation and a deployed infrastructure system is vast and it can only be bridged by sound engineering, clear policy, pragmatic economics, and operational discipline.

From pioneering biogas and landfill gas projects in the early 2000s, to islanded grid development across Africa and Asia, to modern commercial and industrial microgrids in the U.S., the common thread in my work has been deploying infrastructure that performs reliably in the field, not just on a balance sheet or in a feasibility study.

Beyond project execution, I regularly contribute to the global dialogue on infrastructure transition. I joined the British Prime Minister’s trade delegation to Africa in 2018 and have addressed audiences at the United Nations COP23, COP24 and COP26 summits, Microgrid Knowledge, DICE, Data Center Dynamics, and numerous other international industry forums.

My work and commentary has appeared through organizations including the BBC News, CNBC Africa, Infrastructure Investor, Data Center Dynamics, Microgrid Knowledge and POWER.

Governance and Advisory Roles

Good infrastructure depends on rigorous stewardship. Alongside my executive roles, I have served in statutory, charitable, and industry governance positions for over twenty years, shaping how I evaluate risk, board oversight, and long-term capital allocation.

  • Industry Leadership: I serve as Vice President and Management Board member of the COGEN World Coalition, sit on the Council of the World Biogas Association, and contribute to the iMasons Climate Accord Power Working Group (chairing sub-groups focused on behind-the-meter generation and international power dynamics). In 2009, I was also a founding member of the UK’s Anaerobic Digestion and Bioresources Association (ADBA).

  • Commercial and Not-for-Profit Governance: Early in my career, serving as Company Secretary for an early-stage environmental tech business provided a firm grounding in statutory responsibilities. Later, as Trustee and Board Director for Call Plus (now Being There), I oversaw financial governance, strategic rebrand initiatives, and organizational continuity to support individuals facing life-limiting illnesses.

These roles reinforce a central principle: governance obligations and fiduciary duty are just as critical to infrastructure resilience as engineering integrity.

What This Site Is For

This site brings together original commentary, industry analysis, and a record of my work spanning more than twenty years.

It is not a portfolio. It is an effort to make the thinking behind complex energy decisions transparent and actionable for investors, developers, and policymakers navigating a rapidly shifting sector. Everything here is written from the perspective of someone who has spent two decades building energy systems in challenging environments.
