Zak Mir talks to Paul Emmitt, CEO of Powerhouse Energy, about recent progress at the company, including its pioneering integrated technology that converts non-recyclable waste into low-carbon energy, and its revenue-generating engineering consulting division. They discuss PHE's proven technology, its projects and newsflow drivers.

Powerhouse Energy: Turning Non‑Recyclable Waste into Low‑Carbon Energy

Powerhouse Energy is positioning itself where two urgent problems intersect: mounting non‑recyclable waste and the need to decarbonise industrial energy. The company has developed an integrated waste‑to‑energy solution that converts difficult waste streams into useful products — syngas, hydrogen or power — using a robust, proven process based on a rotating kiln.

What Powerhouse Energy offers

At its core, Powerhouse Energy provides a technology platform and engineering capability that turns problematic waste into real value. Rather than competing with recycling, it tackles the residual fraction that typically goes to landfill or is incinerated.

Key outcomes the company targets:


  • Production of syngas that can be used for power or as a chemical feedstock

  • Hydrogen production from syngas

  • On‑site power to reduce reliance on grid electricity or volatile natural gas

  • Support for corporate decarbonisation and waste management strategies


How the technology works — simple and proven

Powerhouse Energy’s process is a gasification system built around a rotating kiln. That configuration brings two advantages:



  • Robustness — rotating kilns are a proven industrial technology with predictable behaviour and maintenance profiles.


  • Flexibility — the system handles a wide range of non‑recyclable feedstocks and produces a controllable syngas stream for different downstream uses.


The downstream equipment—gas cleanup, conditioning and conversion units—uses established industrial technology, which lowers technical risk for potential customers and investors.

The Feedstock Testing Unit: the turning point

One of the most important recent milestones was the completion of a feedstock testing unit (FTU) at the company’s Brandon site in March last year. The FTU serves several crucial purposes:


  • It lets potential clients bring their waste and see how it performs through the process.

  • It provides a platform for ongoing R&D and for tuning the process to specific feedstocks.

  • It acts as a commercial proof point that the technology works at scale prior to a full build‑out.

As the CEO put it succinctly:

"The technology is here for people to see and see work."


Commercialisation pathway and project landscape

Powerhouse Energy is working across several geographies and project types, from licensing and royalties to design‑build‑operate models where it retains control of delivery.

Current project highlights and opportunities include:


  • An Australia project operating under a licensing and royalty arrangement, where the client controls the timeline and delivery.

  • A proposed design, build and operate facility at Balamina (planning application submitted), which would allow the company to drive the project and capture engineering revenues.

  • Active discussions in the Middle East, Europe and the Caribbean for a mix of larger and smaller commercial units.


Importantly, many enquiries are becoming tangible opportunities: in the past 12 months the company received roughly 50–60 enquiries and has around a dozen genuine opportunities under discussion. That pipeline is a positive signal of market interest.

Why market valuation lags — and what will change it

Powerhouse Energy’s market capitalisation sits around £15 million, while the global waste‑to‑energy market runs into the billions. That gap reflects the typical early‑stage dynamic: technology proven at demonstration scale must cross the commercial threshold before valuations re‑rate.

The decisive inflection point will be a signed contract for the first commercial unit. That could be:


  • The Australia project concluding financial due diligence and executing the contract

  • A smaller commercial unit (2.5–10 tonnes per day) sold to a customer to prove on‑site commercial operation


Obtaining a first commercial order validates technology, starts revenue recognition and reduces perceived risk for future customers and investors. The company is open to creative commercial structures to overcome the "nobody wants to be first" problem, including moving or deploying the FTU to a partner site as a demonstration of commerciality.

What to watch next

For anyone tracking the company, the next major newsflow drivers are clear:


  1. Execution of the first commercial contract — Australia or a smaller pilot commercial unit.

  2. Planning approval and progression of the Balamina design‑build‑operate project.

  3. Closing one of the mid‑sized international opportunities in Europe, the Middle East or the Caribbean.

  4. Deployment options for the FTU to accelerate commercial proofs and client acceptance.


Where Powerhouse Energy sits in the energy transition

There is sometimes a binary narrative that only electrification and “100% renewable” solutions are green. In practice, the waste problem persists and requires pragmatic, low‑carbon solutions. Powerhouse Energy is not positioned as a replacement for recycling but as a complementary pathway: it deals with materials that would otherwise be landfilled or poorly controlled incinerated.

By turning that residual waste into syngas or hydrogen, the company helps organisations meet waste management targets, reduce fossil fuel dependence for site power and advance decarbonisation strategies in industries where waste remains an intractable problem.

Summary

Powerhouse Energy has moved from concept to demonstrable technology. With a functioning feedstock testing unit, a growing pipeline of enquiries and concrete projects under discussion, the company’s next milestone is commercial traction — a signed first unit. When that happens, it will mark the transition from technology validation to revenue generation and should materially change market perception.

For organisations wrestling with non‑recyclable waste and industrial decarbonisation, Powerhouse Energy offers a pragmatic, proven route to convert waste into useful, low‑carbon energy streams.
