Replace coal and oil with renewable natural gas (biomethane) by Ocean Foresters

How does this plan reduce the carbon footprint? If each molecule of CH4 burns to two water molecules and one carbon dioxide molecule, then we are still pumping CO2 into the air instead of sequestering it.

Draft biographies for the 20+ scientists and engineers on the Ocean Foresters team are listed in Mark's profile. (As is Mark's.) We can substantially improve the nexus between the Electric power sector, the methane economy, and our ocean seaweed forests with information from our three concepts the Paul G. Allen Ocean Challenge and finalists revisions in: Hydraulic fracturing; Scaling renewables; Replacing diesels; and Agriculture and forestry. Mark57g - The seaweed ocean forests ecosystem has two CO2 capture-and-store opportunities. 1) The bio-CO2 produced during anaerobic digestion. 2) The combustion CO2 captured in the exhaust of CH4 combustion.

We found that this proposal lacked focus -- we recommend focusing exclusively on biogas harvested from seaweed, which needs to be described in greater detail in terms of technology, challenges, etc. Proposal may also be better suited for a different contest. We welcome you to keep developing your ideas with the CoLab community and your colleagues, and entering again next year. Thank you for engaging with the CoLab!
