ABOUT US

Our Mission is to mitigate climate change through low-carbon algal biofuels

Viridos is working with microalgae, building a scalable platform for low-carbon intensity biofuels, which can decarbonize entire industries from aviation, commercial trucking, and maritime shipping. Through this process, Viridos is creating products that are in harmony with nature and providing solutions needed for a greener, more prosperous future.

By establishing production sites to grow Viridos-engineered microalgae in saltwater, we are creating the foundation for a biofuel future that moves away from fossil fuels without competing for precious resources such as fresh water and arable land.

As we move closer to commercialization, our team of scientists are developing more advanced bioengineering tools and knowledge to create new products and processes that will support a sustainable bioeconomy.

ABOUT US

Multiple benefits of the Viridos technology

  • Decarbonizes two difficult to abate industries: Aviation and Heavy Transport
  • Creates new agronomic opportunities that don’t compete with traditional farming
  • Puts otherwise unproductive land into sustainable production
  • Provides jobs and careers across the entire education spectrum from farm workers to Ph.D. scientists
  • Direct and indirect economic impact
  • Provides a strategic fuel alternative for the United States and our allies, for example, Australia, to supply fuel to the Pacific Rim region.

Our mission is nothing less than helping
to save the planet.

We are creating solutions for sustainability that don’t yet exist.

At Viridos, our purpose is to design, bio engineer, and deploy microalgae to produce algae oil at scale as the preferred feedstock for renewable fuels. Particularly for airplanes, trucks, ships, and trains, where payload and range are essential, the need for an energy-dense liquid fuel will only grow. The challenge is therefore, how to replace existing fossil jet fuel and diesel with sustainable and scalable alternatives?

Sustainable aviation fuel (SAF) and renewable diesel (RD) already exist but the bio-feedstocks from which they are refined are of limited quantity and they are often produced from plant oils. As demand for SAFand RD continues to grow rapidly to reduce greenhouse gas emissions, we are running out of options. Producing plant oil at the quantities needed is severely limited by the amount of arable land and freshwater resources available. This creates an unacceptable compromise: grow crops for food and feed, or divert them to produce biofuels?

We have a bold mission: break that compromise through our proprietary and sustainable high oil-producing microalgae that grow in saltwater in sunny and warm climates in algae farms built on marginal land. These algae farms can scale as they can be built on unused arid land and rely on ocean water, not freshwater. By achieving areal oil productivities that far surpass any crop plant, large quantities of algae oil can be sustainably grown on much less land.

While this is a bold mission, at Viridos, we have some unique capabilities that enable us to achieve it. These include continuous genomic innovation, systems to maximize biological productivity, a sensor network platform to enable precision agriculture for algal cultivation, and scalable deployment platforms.

We are replacing today’s unsustainable approaches with products and processes that reduce greenhouse gas emissions and ultimately help create a future where we all can thrive. 

We are excited to welcome new partners and investors as we move closer to commercialization.

They are joining us for five simple reasons:
Urgency of our mission – We are tackling one of the most vital, but hardest to decarbonize, segments of our economy – heavy-duty transportation. It’s an urgency that’s hard to ignore.
Genomic expertise – Our unparalleled scientific achievements are evidence of an IP toolkit and skilled team capable of tackling even greater challenges.
Translating from lab to the real world – Converting lab-based innovations into real-world applicability is fundamental to achieving our Purpose.
Sustainability of our solution – Minimizing land and freshwater use and maintaining ecosystem compatibility are only a few examples of meeting our goal to provide future generations with solutions, not more problems.
Scale of our vision – Our commitment to working with world-class partners is at the heart of our vision and defines the global scale of our solutions.

We've been innovating on behalf of the planet and its residents since 2005.

Since our founding, we’ve pioneered genomic innovations that have been incorporated into new technologies, spun off into companies across multiple industries, and codified in more than 100 patents.

Viridos is a California-based biotechnology company
harnessing the power of photosynthesis in microalgae to mitigate climate change.

Founded as Synthetic Genomics (SGI) in 2005 by leading figures in synthetic biology, including J Craig Venter and Nobel Laureate Hamilton Smith, SGI quickly established itself as a powerhouse for innovative research, transplanting the first genome, synthesizing the first bacterial genome, and creating the first synthetic cell. Over more than a decade, we’ve created a legacy of genomic innovations, building the tools, scientific data, and applied knowledge to address unsolved sustainability challenges. We are now applying our synthetic biology expertise with a complete focus on humanity’s greatest challenge: climate change.

To reflect our complete focus on microalgae for a greener future, we renamed the company in 2021 to Viridos, from viridis = green, fresh in latin, os = operating system that powers a cell.

 

We’re a team committed to building transformative solutions to address climate change.
