China is the world’s fastest-growing market for the clean-tech industry. Despite latent skepticism, many see much opportunity in China for entrepreneurial activities, but only a few have actually acted on it.

ABO member Accelergy Corp. is one of several algae companies that have decided to act. Based in, Accelergy is working with Chinese partners to develop and deploy its algae-based technology that captures CO2 and converts it into biobased products, most notably a fertilizer. According to the agreement, Accelergy will be leading the international effort to deploy the technology (including facilities in the North America), while SARI will be managing the commercialization in China.

TerraVia and VMG Partners have formed TerraBrands: a venture to bring algae into mainstream food markets. As a recent Fortune article explains, the partnership is very natural. TerraVia has a strong background in the algae-industry and VMG has the capital and experience necessary to break into the target markets.

This isn’t new territory for VMG, which works with other health-focused companies, but it is certainly a new venture for TerraVia. Just this year, TerraVia changed its name from Solazyme and shifted its focus from algae-based biofuels to algae-based food products.

Although TerraVia’s products are relatively new to the space, algae as in ingredient is not new to the food industry. It is a widely-accepted superfood and has made its way into products as popular as Naked Juice.

The future for this new partnership seems bright. As Kara Cissell-Roell of VMG points out, there is a “massive opportunity” in the space and TerraBrands is planning to capitalize on it.

Algae technologies have a unique potential to use the CO­₂ from fossil fuel power plants as they grow, transforming what is now considered a harmful waste gas into a valuable feedstock for countless products.

The U.S. Department of Energy’s (DOE’s) Office of Fossil Energy is seeking information from industry, academia, research laboratories, and others to learn about specific beneficial carbon use and reuse technology opportunities for the U.S. power generation sector. The Bioenergy Technologies Office is also interested in employing bioenergy feedstocks as carbon utilization technologies.

To complement existing efforts to develop, demonstrate, and deploy carbon capture technologies, DOE is interested in supporting new and innovative approaches to beneficially utilize CO­₂ from fossil fuel power plants. These technologies include biological utilization technologies, such as algae cultivation.

As we noted in a recent post, Carbon Balance and Management journal published a study in late 2015 touting the emissions reduction potential of algae when used as animal feed. The authors highlight the tension between food security and bioenergy production and point to the simple solution of using commercially grown algae as a partial feed substitute. Algae’s land-sparing qualities mean that it could address food scarcity and land issues at the same time.

A key tenet of the study deserves a deeper dive: that on a large scale, the use of algae as animal feed establishes the conditions “for cascading greenhouse emissions savings and a return to preindustrial atmospheric carbon concentrations.”

Yet even at small scales the incorporation of algae into animal feeds could have a significant effect, much more so than marginal improvements in bioenergy production. Table 3 of the study (shown below) charts the projected atmospheric CO2 concentrations in the year 2100 based on the results of the model used in the study. According to the table, if 10% of feeds were algae-based and 25% of emissions were sequestered using CCS, global warming would be limited to 2 degrees. Any further increase in application for either CCS or algae as a feedstock would march towards being a carbon sink.

Although perhaps a hypothetical analysis like this should be taken with a grain of salt, it is nonetheless a remarkable result that algae and CCS could together act as such a significant pathway towards limiting global emissions. And in many ways an even more remarkable result that an impact could be had with modest introduction of either.

The use of algae as a feed for animals has the potential to play a big role in limiting global carbon emissions while also providing the world with more sustainable protein sources, according to a new study published in Carbon Balance and Management. In fact, the authors find that algaculture combined with a modest amount of carbon capture and sequestration could even help bring atmospheric carbon concentrations down to preindustrial levels by the end of the century.

The study, ‘New feed sources key to ambitious climate targets,’ quantifies the emissions reduction potential of using algae as a feedstock by modeling  the social, environmental and economic impacts of various technology development scenarios.

The detailed analysis shows that cultivating algae for use as animal feed would have a significant effect on emissions at any scale. Even without the application of CCS the use of algae as animal feed could be expected to limit global temperature change by as much as 0.7° C by the year 2100. That’s quite a large portion of the temperature changes that are expected to occur due to climate change without significant mitigation efforts.

The promise of algae-based feeds exceeds that of other biomass solutions, which all too often face competition for arable land and freshwater supplies. Algae, on the other hand, can be grown on marginal lands, using saltwater or wastewater, and produce yields many times that of traditional crops.

The bottom line for agriculture is that algae-based feeds, which have been proven to be equal to other feeds in nutritional value and digestibility, could free large swaths of arable land while addressing the food security issues that come with a growing global population.

Based on feasible costs, the authors estimate that algae could have supplied 40% of global feeds in 2013 for between $420-920 billion USD (2013), highlighting as a comparison the $550 billion USD (2013) given in fossil fuel subsidies that year.

While the authors do site some challenges that come with deploying new technology, such as the expansion of carbon capture and storage and production of algae at a large scale, they highlight the fact that the use of algae as a feedstock can have an impact on virtually any scale and that the effort would be technologically feasible.

In the words of the authors, algae-based animal feed is a “promising and simultaneous solution to food security and climate change and these systems merit greater attention and closer scrutiny than they have thus far received.”
