Independent
Vendor-neutral
Engineer-led
Engineering complex energy systems from concept to operation.
Since 2017, TOKEF has worked where others hesitate: residues, waste streams and biomass that carry more risk than reward for conventional engineering — and more energy than their owners realize.
We are engineers first. Our recommendations are vendor-neutral, grounded in laboratory fuel data and process modelling, and carried from feasibility through FEED, procurement, construction and commissioning by the same technical team.
The result is not a report on a shelf. It is a plant that runs, an emissions file that closes, and an operator team trained to own the asset after we leave.
From fuel characterization to plant optimization — each practice reinforces the next, so decisions made early survive contact with reality.
Gasification converts biomass, residues and refuse-derived fuels into clean syngas — a versatile energy carrier for power, heat, hydrogen and fuels. The technology is demanding; that is precisely where we are strongest.

The same engineers who validate the fuel remain accountable through commissioning. Knowledge does not change hands mid-project — and neither does responsibility.
Objectives, feedstock reality and regulatory context framed into a viable project definition.
Technical and financial validation — fuel analysis, technology screening, economics and risk.
FEED, basic and detail design: process, heat & mass balance, P&IDs and specifications.
Vendor-neutral tendering, contract strategy and EPC negotiation on the owner's side.
Site supervision, QC and execution control against schedule, budget and specification.
Structured start-up, performance testing and acceptance against guaranteed figures.
Operator training, process optimization and long-term technical partnership.
Our methodology combines computational modelling, laboratory measurement and disciplined compliance engineering — so performance guarantees rest on evidence, not optimism.

Quality policy
Every engineering deliverable passes internal technical review before it reaches a client. Every figure we publish traces back to a measurement, a calculation or a standard — and when something cannot yet be verified, we say so.
Every thermal project we advise on starts in the laboratory. Fuel characterization converts assumptions into measured values — the difference between a design that works and one that only looks right on paper.

We apply AI and automation the way engineers should: where they measurably improve availability, efficiency and safety — not where they decorate a slide deck.
Automated control systems engineered for thermal processes.
Machine learning on plant data, ahead of failures not after.
CFD and process models that de-risk design decisions.
AI-driven energy reduction for digital infrastructure.
Decarbonization is not a brochure. It is mass and energy balances that keep residues out of landfill and fossil carbon out of the atmosphere — verified, monitored and engineered into the process.
Residue streams converted into energy products with defined value.
Fossil displacement measured in tonnes, documented per project.
Energy recovery engineered to capture what single-purpose plants lose.
Local fuels, local energy — infrastructure that holds under volatility.
TOKEF Energia was founded in 2017 to develop efficient, environmentally responsible projects with a high technological profile. We hold no technology shareholdings and sell no equipment — our only product is sound engineering judgment.
That independence is not modesty. It is why our feasibility conclusions can be trusted by investors, lenders and boards.
Next step
Talk with engineers who have designed, de-risked and commissioned thermal conversion systems — and who will tell you honestly if a concept does not hold.
