    Modular Microalgae-based CCU systems

    When we think of hard to abate CO2 emitting sectors, we think of cement factories, steel production, and chemical production. Those seem (to me) too duanting a challenge to jump to from scratch when it comes to CCU. How do you scale and learn and improve from nothing to those large and complex and voluminous CO2 emissions. ? The answer is beer !. It turns out breweries world-wide account of a significant amount of CO2 production from the brewing process. 190 billion liters of beer are produced yearly which at ~4kgCO2 per 100liter yields 8Gt CO2 emission from beer. However, there are breweries of all sizes and micro-breweries typically come in at ~200 000l/yr=8tCO2: a more manageable starting point. The idea would consist of developing a modular and cheap low-tech photo-bio-reactor that can be installed into micro-breweries to capture their CO2 emissions. This would offer the opportunity to learn and improve and the modularity would enable incremental steps towards larger breweries and eventually larger CO2-producing industries.
