Get Involved

We know that it works in theory – we need to understand how we can make it work in practice. There are many questions that we still need to answer and we are appealing to anyone who can help us develop this project further.

We are looking for assistance in the following specific areas:

  • Next Steps

    We intend to develop the process through using your insight and experience.
  • Energy Balance

    The process requires energy: energy to quarry the limestone, energy to crush it into pieces, energy to calcine it into lime and energy to dispose of the lime in seawater.
  • Economic Viability

    The process requires money: money to extract the limestone, money to purchase the fuel, money to transport the materials, money to pay the capital cost of the equipment, money to operate and maintain the equipment and money to manage the process.
  • Environmental Impact Assessment

    The process will have impacts on the environment: on terrestrial systems due to mining activities, on atmospheric systems due to the calcining process, on aquatic systems due to disposal of lime into seawater.
  • Legal Considerations

    The process needs to operate within the bounds of the law.
  • Potential Locations

    The process needs to be located somewhere: somewhere where the required raw materials are cheaply available and sufficiently closely located to one another to be practical and economic to be useful.
  • Energy Sources

    What kind of energy could be used to drive the process: fossil fuels are used to drive the calcination reaction in existing plants, but what other sources of energy could be used? Solar irradiation, geothermal, wind, wave, nuclear.
  • Growing Biomass in Arid Environments

  • Website Development

    This website is integral to the open source development of the process.
  • Policy Implications

    If the process works as intended and produces a robust and economic carbon negative process, then it will have profound implications on public policy.
