DailyDirt: Blooming Business For Algae
from the urls-we-dig-up dept
Growing fuel from algae is a goal that plenty of scientists have been working on for years. Creating an economically viable process for doing this would be a real game-changer, but so far, there are still some major challenges (and the price of oil is looking remarkably low nowadays, too). Still, progress for growing biofuels from algae is inching along, and here are just a few examples.- One of the problems for using algae to produce biofuels is that these organisms normally produce lipid oils when they are starved for nutrients -- but they don't grow well under those conditions. However, engineering some diatoms to produce lipids without hindering their growth has been achieved. [url]
- An algae pilot plant in Alabama is making diesel and jet fuel -- and treating waste water at the same time. Algae Systems puts waste water, algae and CO2 into large plastic bags and lets the algae grow for a few days offshore in the sun. This process currently produces 3,000 gallons of fuel per acre per year and treats 40,000 gallons of water per acre per year, so it still needs to scale up before everyone is driving/flying around using this biofuel.

- An algae-powered building in Hamburg relies on heat from growing algae to make the building (somewhat) self sufficient. This BIQ building sucks carbon dioxide out of the air, creating biomass, and uses traditional solar panels to augment its power needs. The upfront building costs are significant, but if it can continue to operate with minimal ongoing energy costs, the investment will pan out in the future. [url]
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

history is repeating ... yet again
In the late 1970s, there was a fortune spent on research and development (the bulk of it taken out of the hides of US taxpayers) into so-called "synfuels" -- alternative-energy projects that were dumped within a few years when the Republican-led government pulled the plug on funding, and the final nail in the coffin for synfuels was when the price of petroleum collapsed (and then remained low for the next quarter-century).
Today, getting fuel from algae (or any other farmed crop) would simply be a huge money-loser for as long as petroleum prices remain low, which could be for many years to come (largely depending on US-Russia relations).
But it's indeed funny how these things appear to run in predictable cycles. Which coincidentally, like women's clothing fashions historically have, repeat about ever 30 years. :)
