EWM | Carbon capture
Cheaper than a plant without it
Source
Carbon Capture Journal Newsletter
Description
Compared to a standard gas power plant, the working fluid is CO2, rather than water/steam.
Benefits
Operational costs are lower (compared to a standard gas power plant) because CO2 is a more efficient working fluid than steam. This is true even when the energy demand of the air separation unit (to create oxygen inlet stream) is taken into consideration.
Risks/Disadvantages
The heat exchanger in the CO2 cycle needs to be large to improve the cycle efficiency, while existing turbines for steam and gas are not suitable for CO2 yet (ref. to Moullec, Energy Procedia, 2013 (37), pp 1180).

Science Alert, 4 Nov 2014
Description
The team at Cloud Collective, Switzerland aimed to create an algae garden that uses the highway’s excess of carbon dioxide coupled with sunlight to transform the polluted landscape into a smart space for urban farming.
The system itself is quite simple, the algae are cultivated inside tubes, and a series of pumps, filters and solar panels aid the process.
Benefits
Once the algae mature, they can be produced into a number of different products, including biodiesel, nutrients, medication and cosmetics.
Rish/disadvantages
Economic viability of the system is still uncertain

Description
A highly sophisticated, multi-vessel photobioreactor (PBR) is being developed by the scientists at Cawthron Institute, New Zealand to improve the production of high value algae products. The Cawthron scientists developed the PBR in response to their industry partner’s needs to optimize the growth conditions of algae species.
Currently, the new technology PBR is under trial for algal growth models and it will be scaled up for the commercial use.
Supreme Biotechnology, a New Zealand- based Nutraceutical Company known for the high-value algae compound astaxanthin, is keen to utilize the new equipment to optimize their algae growth on a commercial scale.
Benefits
Improved production high-value algae products.
Rish/disadvantages
The algae production is still largely at a laboratory scale and there is little information about algae production at a large/industrial scale (Koller et al., J. of Cleaner Production, 2012 (27), pp377).
