Capitol Aggregates and Skyonic are progressing with plans to install CO2 capture technology at Capitol’s cement mill in San Antonio, Texas.

Skyonic has worked with Zachry Corporation, owner of Capitol Aggregates and engineers Ford, Bacon & Davis to complete Phase 1 project design work, which received a grant of $3 million from the US Department of Energy and the National Energy Technology Laboratory.

The Capitol-SkyMine plant, expected to be operative by 2014, is designed to capture around 75,000 tonnes of CO2 from flue gas emitted by the plant and recycle the emissions into hydrochloric acid, sodium bicarbonate and other byproducts.

In 2010, Skyonic received a $25 million grant from the  DoE to develop its proprietary carbonate mineralization technology, SkyMine®, which will be deployed at the cement mill. It has been successfully testing pilot SkyMine technology at the plant since then.

Timing

Skyonic broke ground in October 2013 and it is expected that the plant will be starting up in 2014.

Finance

The total cost of the capture facility is estimated at $125 million. The project has to date received $3 million in Phase 1 funding from the DoE and NETL. Skyonic has received $25 million from the DoE to develop its SkyMine® capture technology.

In mid-2012 the project attracted new funding partners Northwater Capital Management, ConocoPhillips, BP, and PVS Chemicals, who will now support construction costs and other R&D and operations.
