AGL to add CO2 capture to Torrens gas power plant in Adelaide

AGL Energy has revealed plans to build a state of the art carbon capture plant at its Torrens Island gas power station near Adelaide, Australia’s largest natural gas-fired generator.

The utility has partnered with French-based industrial gases company, Air Liquide, to develop the facility, which is expected to capture and purify up to 50,000 tonnes of CO2 emissions from the 1280MW power station’s exhaust a year.

The CO2 recovered from the plant will then be used in applications including the carbonation of beverages, carbon dioxide snow for the wine industry, waste water treatment instead of using acids, and in public swimming pools.

There was no mention, however, of how CO2 recovery at the plant might be affected after 2017 – the year AGL plans to retire more than one-third of the capacity of Torrens Island, which it bought in 2007 for $417 million.

AGL said in December 2014 that it would shutter four out of eight of power station’s generating units – a group of the plant’s “older units” (built nearly 50 years ago) known collectively as ‘A station’, with an aggregate capacity of approximately 480MW.

“Based on the current market outlook AGL has decided that the Torrens Island A station will be mothballed in 2017,” said AGL Group general manager of merchant energy, Anthony Fowler, adding that the decision would be reviewed if those conditions – including rising gas prices – changed materially.

Regardless, the Torrens carbon recovery plant will be the first of its kind in South Australia to capture CO2 from existing emissions, and the first to capture carbon from a power station for the CO2 market in Australia.

The project also fits with AGL’s recent corporate makeover, which has seen the establishment of a renewables-focused New Energy division, the launch of an energy storage product, and the release of a Greenhouse Gas Policy, committing to decarbonisation of its electricity generation by 2050.

“Innovative processes such as the Air Liquide CO2 recovery plant will be critical in helping reduce emissions from the electricity generation sector,” said AGL managing director and CEO Andy Vesey in a statement on Thursday.

In Victoria, AGL has a post combustion capture pilot plant at its Loy Yang coal power plant that’s been operating since 2008, with plans to build a second at the site by the end of 2015. Both Victorian plants are part of a carbon capture storage research project with the CSIRO.

Construction will begin soon on the SA plant, which is expected to be operational by the second half of 2016.

    I can see it now. Abbott parading the carbon capture as a solution for the future. And while it is better than nothing it is widely accepted that carbon capture is yet another attempted lifeline for coal. Think of it as smoking cigarettes through 3 filters instead of one – it’s still going to cause you harm because it is fundamentally dangerous.

    And for anyone interested here’s a great read on the optimism coal still has – despite everything. http://www.canberratimes.com.au/business/mining-and-resources/glencores-peter-freyberg-defends-coal-20150604-ghgajs

      The coal industry increasingly looks like a bunch of turkey’s prepared to celebrate Christmas;)

    Burning Natural Gas produces 550g CO2 per KWh = 550t per GWh. Rated at 1280 MW the Torrens Island gas power station at 100% capacity 24x7x52 would produce 11,200 GWh per year producing over 6 million tonnes of CO2. Capture of only 50,000 tonnes is an insignificant 1% of the plants CO2 emissions.

    This scheme is CC not CCS i.e. there is no storage of the CO2. Rather like some weird eco-sensitive sports fishing for CO2 “capture and release”….

    Developing profitable applications for carbon dioxide might be a good thing.
    Algae Tec has commercialised a process that needs a reliable supply of low cost carbon dioxide to feed algae. The process also uses concentrated sunlight to increase the growth of algae.
    Algae can produce edible oils and compete with palm oil plantations. This is an example where converting carbon dioxide into a raw material could reduce rainforest destruction.

      As with the Torrens Is. scheme, Algae Tec’s process is not sequestration. The overall path is still underground to atmosphere. At best, it halves carbon intensity. Not good enough to solve the problem we face.

    Hm.. if they could capture some Argon while they’re at it prices for welding gases might come down a bit, mostly just for stainless steel, but hey 😉

    Make no mistake, this has NOTHING to do with carbon capture AND storage, this proposal will not improve the GHG profile,of this generationg plant whatsoever. This is merely an ancillary profit boosting system. Whether the CO2 is released directly out the plants stack or 3 months later from your beer is irrelevant, you have still taken geologically sequestered CO2 and added it to the atmosphere.
