Leigh Creek Energy Ltd (ASX:LCK) is making significant progress at the pre-commercial demonstration (PCD) facility at its Leigh Creek Energy Project in South Australia, with gas flows continuing for 53 days.

LCK is aiming to produce high-value products such as electricity, methane and fertilisers from the remnant coal resources at Leigh Creek, utilising in situ gasification (ISG) technologies.

Development of a typical ISG chamber: The Leigh Creek facility is currently in the pyrolysis stage

As the temperature and consequent size and configuration of the gasification chamber increase, conditions develop exponentially for stable gasification processes to be maintained, typically at temperatures above 1,000 degrees Celsius.

The principal chemical reactions during this phase relate to the interaction of very hot gases interacting with the coal to form syngas (synthetic gas).

This is the commercial gas production phase which the company is continuing to work towards.

Gas flows have been continuing for 53 days

LCK managing director Phil Staveley said : “The PCD is developing as expected, both technically and operationally.

“LCK’s on-site operations team and Adelaide based technical experts continue to manage the development of the PCD gasification chamber toward commercial flow rates, by managing the gasifier’s operating parameters, such as pressure, water inflow and outflow rates.

“This process is continuing and importantly has not stopped since the gasifier was initiated on 10 October 2018.

“Through this we continue to work closely with the regulator to ensure appropriate oversight.”

LCK’s recent progress is bringing the company closer to commencing the process to upgrade a portion of its 2,964 2C resource to proven and probable reserve status.

The company’s major objective is to achieve commercial syngas flow and commencement of the resource upgrade process in Q4 2018.
