[geo] Geoengineering, Marine Microalgae, and Climate Stabilization in the 21stCentury

[Michael Hayes]

This is a well done paper. Solving for the energy, nutrient, water, and 
regulatory nexus may, however, be best found through establishing the 
cultivation infrastructure on the high seas beyond the EEZ.

I currently have a proposal submitted to ARPA-E for the development and 
deployment of such an offshore installation.

Best regards,
Michael

KEY POINTS

  *   Industrial microalgae cultivation offers many advantages to help society 
achieve its climate stabilization targets.
  *   Microalgae‐derived biopetroleum products can contribute to mitigating and 
reversing effects of CO2 emissions.
  *   Microalgae cultivation can play important indirect role in reducing CO2 
emissions by displacing conventional agriculture.


Abstract: Society has set ambitious targets for stabilizing mean global 
temperature. To attain these targets,
it will have to reduce CO2 emissions to near zero by mid-century and 
subsequently remove CO2 from
the atmosphere during the latter half of the century. There is a recognized 
need to develop technologies
for CO2 removal; however, attempts to develop direct air-capture systems have 
faced both energetic and
financial constraints. Recently, BioEnergy with Carbon Capture and Storage 
(BECCS) has emerged as a
leading candidate for removing CO2 from the atmosphere. However, BECCS can have 
negative consequences
on land, nutrient, and water use as well as biodiversity and food production. 
Here, we describe
an alternative approach based on the large-scale industrial production of 
marine microalgae. When
cultivated with proper attention to power, carbon, and nutrient sources, 
microalgae can be processed
to produce a variety of biopetroleum products, including carbon-neutral 
biofuels for the transportation
sector and long-lived, potentially carbon-negative construction materials for 
the built environment. In
addition to these direct roles in mitigating and potentially reversing the 
effects of fossil CO2 emissions,
microalgae can also play an important indirect role. As microalgae exhibit much 
higher primary production
rates than terrestrial plants, they require much less land area to produce an 
equivalent amount of
bioenergy and/or food. On a global scale, the avoided emissions resulting from 
displacement of conventional
agriculture may exceed the benefits of microalgae biofuels in achieving the 
climate stabilization
goals.
