Algae: The Next Frontier

We’re warming. I know this may seem hard to fathom, especially when many of us are struggling to fit as many sweaters as possible under our winter jackets just to take a walk outside, but we are warming.

And it’s not pretty. Globally, we are running out of chocolate, houses are crumbling, California is in drought, and the Netherlands is sinking.

carbon_captureTwo words:

Carbon. Capture.

Well, technically, the proper nomenclature is four words: “Carbon Capture and Storage”. Otherwise known as CCS, Carbon Capture and Storage is the process of capturing greenhouse gas emitted by large industrial plants, compressing this gas for transportation, and then injecting it into a rock formation, where it can be permanently stored.

But that’s just one method.

Today, much of the gasoline in the U.S. and Brazil encompasses somewhere around 10% ethanol, which is essentially corn (and sometimes sugarcane) turned into fuel. The limitation with ethanol is that for this concept to truly be scalable, corn would have to dominate farmland. In other words, unless we want to live in cities inundated with corn stalks, there’s simply not enough space.



Algae, similar to corn, are able to sequester carbon out of the air. The competitive advantage here is that 70% of the earth’s surface is unused water. Algae does not require tending to.

But the end game is turning sequestered carbon into fuel, and this is not being done on a commercialized basis.


…Why not? Glad you asked. Three major reasons.

1. Strain development – in other words, not all algae are created equal. Some algae are more efficient at sequestering and churning carbon. The struggle lies in finding the algae.

2. Cultivating and harvesting – algae are floating everywhere. Scientists and environmentalists have been striving to find a way to efficiently capture these floating plants.

3. Extraction – unearthing crude oil from algae is not easy. There are refineries dedicating to performing such a task, but it is not cheap.

Algae to fuel is hardly a new concept. What’s new is that recent breakthroughs in technology have enabled the cost to come down to about $7.50 per galloon.

This is progress, but it is not enough.

The Department of Energy has granted $48.6 million dedicating to developing a fuel source from algae. Yet, this is just a drop in the bucket. Here’s the real problem. Oil companies should be doing more than just lip service. Exxon, Chevron, Shell and the other big players have expressed interest, but there has been very little action.

We should all be dreaming of the day when we go to the gas station and say “Fill me up with some green algae please!”

  1. That’s amazing! $7.50 seems close to getting to commercialization. I did not realize we were that close. Thanks.

    1. Kyle – thanks for reading! When it comes to technology, efficiency and cost are negatively correlated. This is an amazing, and hugely important, characteristic of technology. We see the same concept with solar energy and grid parity. The cost of installing solar panels has drastically decreased to the point where we have reached “grid parity” (the cost of installation is equivalent to or cheaper than purchasing electricity from the grid) in approximately 80 countries.

  2. If the oil companies want this, then it will happen!

  3. Agreed. Royal Dutch over here on this side of the pond has been trying to get several carbon storage schemes underway – associated with utilities. No progress yet, but sounds great ! Hope there is more progress on these projects. far too little so far Cheers!

  4. Jeremy – thanks for weighing in. The UK efforts are highly commendable. I was actually in London earlier this year to learn more. Cheers – TSI.


  5. Great post, TSI. I bet the oil companies will get really interested when someone outside of their world figures out how to make algae-based fuel at, say, $2/gallon. Sounds like that’s not pie-in-the-sky. Keep up the good work.

    1. Thanks greensportsblog. $2 / gallon algae-fuel would be incredible!
