Around the Pier: Could Algae Kill Two Birds with One Stone?
New collaboration will test organism’s ability to consume greenhouse gas and create an energy source
Scripps Institution of Oceanography at UC San Diego and Southern California Gas Co. (SoCalGas) will design an innovative system in which algae consume carbon dioxide (CO2) emissions from natural gas combustion and cost-effectively convert it into valuable byproducts such as biomethane, biodiesel, and animal feed.
For several years, researchers at Scripps and a number of commercial companies around San Diego and elsewhere, have been studying how algae can most efficiently be developed into a clean, renewable biofuel to one day replace non-renewable fossil fuels. Taking this research a step further, Scripps’ researchers hope to leverage algae’s natural ability to absorb CO2 in the environment and convert it into oil rich biomass or biomethane or refined fossil fuel replacements. After extracting the oils for biodiesel, the remaining biomass can be sold as a safe, protein-rich animal feed.
The new collaboration between Scripps and SoCalGas includes an investigative research and systems engineering study to explore how algae production systems currently in development could most effectively capture industrial CO2 emissions. Targeted CO2 sources include natural gas power plants, large engines used in natural gas compression and water pumping, and boilers used to produce steam for industrial processes such as enhanced oil recovery.
“If the Phase I analysis proves such systems can be safe and economical, we then hope to enter into a Phase II agreement to help SoCalGas build and operate a module of a commercially scaled system, and test its capabilities at a site to be selected within Southern California,” said Dominick Mendola, a senior development engineer in the laboratory of Greg Mitchell, a Scripps research biologist who is exploring marine algae for their potential as a new biofuel source.
“Recovering CO2 from combustion and turning it into a valuable commodity such as biomethane, biodiesel, or a high-quality animal feedstock is great for the environment while creating valuable products,” said Hal D. Snyder, vice president of customer solutions for SoCalGas. “None of this is easy, but working with world-class scientific organizations like Scripps Institution of Oceanography and UC San Diego greatly improves our chances of success.”

Ok, after reading this, my head exploded. We’re trying to use algae to consume greenhouse gas? How do you guys come up with these ideas? Lol. I’m glad you do though.
Is it just me or is California the one always on the cutting edge of green technology?
Could algae, perhaps NOT defatted, provide an emergency food for polar bears? I have visions of big bales of the stuff on floating ice islands, perhaps anchored to the ocean floor, throughout the ice free area of the Arctic, ice islands produced by giant ice makers that run on ocean current energy, wind, and/or solar. It’s not that I think polar bears matter more than humans at all–but I do think having a heart for their needs can focus us on what we ALL need which includes not only fixing the GHG issue, but also working to restore the reflective cover over the Arctic Ocean. Surely building ice makers is far less of a technological feat that making oil drilling platforms, and a lot more necessary. Thanks very much for the algae work!
