An integrated approach to optimise the small-scale XTL facility

XTL ventures are typically large, complex and require high levels of capital investment.

They are also characterised by high failure rates.

We believe that by reducing the scale many of the risks can be overcome.  It is entirely feasible to build smaller scale, manageable and cost competitive XTL plants that unlock energy.

AST can demonstrate that small scale XTL is cost comparable with the leading producers.  The key is a rigorous optimization of the plant that focuses on 4 key elements:


Pre-assembly of plant components to minimise site installation costs.


Design and select each item of equipment for reuse,  avoiding special once-off unique processing units.

Value Chain

Reduce all waste by ensuring that only value adding elements are incorporated into the design.

Business Model

Analysis and optimisation of the total business model to fit localisation needs

What we do

AST works to reduce project risk and improve the economics of a XTL venture by standardising the capacity of a production train to a more manageable scale.

We adopt a rigorous integrated approach to optimising the entire project value chain.


This smaller scale and economic advantage makes this technology ideally suited for unlocking smaller quantities of stranded gas reserves, low quality coal or biomass.

Low risk strategies for growth

The small-scale facility can readily be scaled up when funding permits by adding additional production trains that all follow the same standardised approach,  eliminating much of the complexity and risk of scale up.

The execution and start-up  of subsequent trains is significantly faster leading to a much improved return on the investment.

The outcome

The result is a facility that produces synthetic fuel at a smaller, more manageable scale that is cost competitive compared with the largest scale plants.
