Algae.Tec in deal to convert NSW coal plant CO2 into biofuel

ASX-listed Australian biofuel company Algae.Tec has signed a groundbreaking deal with NSW government-owned power company Macquarie Generation to site an algae carbon capture and biofuel production facility alongside a 2640MW coal-fired power plant in the Hunter Valley.

Announced today, the deal – which it is billing as a “world first” –  will see Algae.Tec build an algal oil plant next to Macquarie’s Bayswater coal-fired power station in the Hunter Valley, where the coal plant’s carbon dioxide will be captured – 270,000 tonnes of it a year – and fed into an enclosed algae growth system and then converted into biodiesel.

Algae.Tec executive chairman Roger Stroud told RenewEconomy in an interview this morning that the agreement represented a milestone for the company, whose primary order of business has been to develop a relationship with a significant CO2 emitter.

Last November, Algae.Tec announced an MOU with German airline Lufthansa, to identify a site in Europe to build an algae plant to produce A-grade biofuel for the airline – a deal that Stroud says hasn’t come to fruition quite yet.

“We now have an agreement with one of the largest coal-power groups in Australia,” Stroud said today. Not to mention one of the country’s largest emitters, who, contrary to popular opinion, “genuinely want to try and reduce their emissions.”

At this stage, Stroud says the company is looking at a price tag of about $140 million for the Hunter Valley project, and is in talks with a US group about a bond issue in Europe, and with three other groups about funding sources.

Algae.Tec hopes to complete the funding round by the end 1st quarter in 2014. In the meantime, they will be conducting a permitting program and feasibility study, with the goal of kicking off construction of the plant by the beginning of 2nd quarter next year – using Worley Parsons, as previously announced – and then commencing production by end 2014.

“It’s a tight timeframe,” Stroud told RenewEconomy, “but we hope that if we can do these things in parallel, we’ll get there. And if we can’t do it by then, it’ll be close.”

Once in production, Stroud says the plant will initially supply biodiesel for use in transport and mining in the Hunter Valley region. To this end, the company has an off-take agreement with Biodiesel Industries Australia, whose Maitland commercial biodiesel plant was the first of its kind in Australia, producing a blended fuel that powers the Newcastle City Council’s car fleet and is sold to Caltex at an order of more than 600 million litres.

Stroud says Algae.Tec hopes it can now help provide a “purer feed” biodiesel to Caltex and others, and then in the longer term, the plant’s algal oil will be hydrogenated to produce A-grade jet fuel as well.

The company says it has learned a lot from its Nowra pilot facility, and developed quite a few innovations that will make the Hunter Valley plant “far more efficient and more flexible,” in that it will be built on a smaller footprint than was originally envisaged.

    Am I missing something here? The CO2 from burning the coal still ends up in the atmosphere, admittedly after being cycled through algae and then diesel? Surely the net result is still global warming by release of fossil fuel CO2?

      I think you are correct, the ultimate carbon intensity is diminished by the amount of fossil diesel displaced (less losses in the process), I suppose in the order of 20-30%?

      Doesn’t really matter where the algae gets its CO2 from – if it absorbs and releases the same quantity of CO2 then the biofuel itself is considered renewable. The net result is that the same release of CO2 from the power station delivers two rounds of energy release. One could also say that the power station’s large scale concentrated flow of CO2 enables the biodiesel to be economic. But you’re right that this solution assumes the power station’s emissions are not capable of change, and doesn’t appear to value the opportunity for the algae to be sequestered/buried as a means of carbon capture and storage.

        Thanks for the comment. I guess sequestering the carbon after having the algae convert it would be a pretty expensive process that would have to make the power generated from the coal uneconomic.

        Bottom line is we need to stop CO2 emissions and the algae thing is a bit like CCS… fiddling at the edges and a smokescreen. How do they clean up the power plant emissions to just deliver CO2 anyway?

        This is mostly true. But you have to consider that the production of biodiesel also results in the generation of glycerol as a by-product. There are technologies around that can utilise this glycerol, and effectively sequester it. Thereby, some of the CO2 from the power plant may end up converted to glycerol and later sequestered. Not an ideal arrangement, but a lot better than pure CO2 emission into the air / use of fossil diesel in transport…

      Glad to see others spotting this. I had a battle getting New Scientist editors to acknowledge it. But it’s the politicians and bureaucrats we need to enlighten. At a guess, the power station dodges C-tax, and since transport fuel is still exempt the secondary emission doesn’t pick up the bill.

    Algae.tec seem fishy to me. Have a look at their 2012 annual report. I have no inside information whatsoever, just didn’t think that the R&D expenditures looked right for a company at the demonstration stage. Algae.tec is paying their top 3 management (about $400k each, $1.2M total) more than they spent on R&D (<$1M). I wonder what someone who knows something about reading an annual report would make of the disclosure that Algae.tec only has ~30 employees, but six of these are members of the Executive Director's immediate family?
