Project Presentation: Sanjana
- We would like to model the net impact of our project in terms of carbon fluxes (emitted and sequestered). What fluxes do you think we need to account for, and what is the level of sophistication our model must provide to be useful to people in the field? Soorya
- Are there any second-order effects that can lead to carbon fluxes? For example, do you think transportation and electrical power required for our project are likely to emit carbon fluxes that we need to consider in our model? How much will it matter if we neglect them? Arsh Yes we need to consider the second-order effects, transportation not so much.
- How big should we make this project for our project to have a measurable difference on the environment? Would we need to convert some particular fraction of petrochemical synthesis to our carbon-capture based method to reach any climatically relevant tipping points? Soorya
- Who would you expect the stakeholders in such a technology to be? How should we engage with them to try and get them to use it? Are there particular regulations or government incentives or a desire to greenwash that you think we can leverage? Arya
- There are many ways to implement our project idea. We could implement it in large-scale factories that capture and use atmospheric carbon, or hook it up to carbon dioxide purified from industrial effluents, or even use it as a self-contained local power source (where we use butanol as a fuel to generate power and then trap the CO2 and use it to reproduce butanol). We're investigating which of these is most feasible from an economic perspective, but what about from a climate perspective? Would you recommend that we prefer any of these over the others? Akash
- How long can we expect the residence times of the carbon we capture to be with our idea? How does this change between succinate and butanol (butanol will be burnt to release CO2 back into the atmosphere, while succinate is used to produce various chemicals)? What do the residence times mean for the potential impact of our project in reducing atmospheric CO2? What other parameters would determine the net impact of our idea on the levels of CO2 in the air? Akash
- Does the geographic location of the plant matter? Are there certain regions where reducing carbon efflux is more urgent? Ashli
- What kind of methods exists for long-term storage of the carbon captured by biomass? How could we modify our existing idea to allow for long-term carbon sequestration? Could you recommend resources on where we could read up more on carbon capture strategies? What are the merits and demerits of biomass-based carbon capture methods?
Extra
- best ways to explain climate change in terms of local effects
- is it feasible for this method to be carbon neutral if not carbon negative?
- other sources for our project (to make it modular), that we can add to our "future plans" section

Meeting Notes:
- We first present our project. Included that we're interested in both butanol and succinate
- Joy: how much co2 is getting fixed? did we consider respiration etc.?
- Is the crude being reduced in your project?
- How many barrels of crude oil will be needed for the current manufacturing for succinate
- Carbon credits, how much can you capture, power req., space req., monetary req.
- what happens to our carbon afterwards
- he thinks it'll get very messy very quickly, we might not need to get into it
- Neena: we don't need to worry about the residence time, what matters is the final product
- Ways to modify our project now to make it long-term sequestrable
- they talked about the natural biological sinks: for eg. plankton and their shells
- plankton ecology is not limited by food though, but more to iron, phosphorous
- they talked about the natural biological sinks: for eg. plankton and their shells
- answers to conversion rates
- bioreactor cost per cubic metre
- flue gases temperature, other toxic compounds
- "Raghu Murtugudde" mahatma@umd.edu
- has worked in carbon sequestration
- can use Neena as a reference
