The large traders ditched algae biofuel final yr, with ExxonMobil amongst these making a rush for the exits. Nonetheless, hope springs everlasting among the many small fry. The US Division of Power remains to be forging forward with new algae-related packages, and a brand new EU consortium is cranking up as nicely.
The Algae Biofuel Conundrum
First, the excellent news. Algae farming may present for a extra sustainable, dependable vitality crop provide chain. As a substitute of utilizing up arable land or mowing over various ecosystems, an algae operation may leverage a broader vary of website places, together with each indoor and out of doors infrastructure.
One sticky wicket is the best way to earn money off the little oil-soaked inexperienced goblins. ExxonMobil supported a longrunning algae analysis mission for greater than 10 years, offering some favorable publicity for itself on the sustainable fuels facet alongside the best way, earlier than formally passing the algae torch in 2023 (see tons extra algae biofuel tales right here).
One other concern includes the general carbon footprint of algae biofuel. Some stakeholders are leaning on the concept of deploying algae farms to absorb extra carbon dioxide from the air. Nonetheless, final yr a real-world lifecycle evaluation indicated that algae biofuel manufacturing may outpace diesel gas for carbon emissions.
A New Hope For Algae Biofuel
That doesn’t imply traders have given up hope. In yet one more “back from the dead” improvement, final October the EU launched a brand new 4-year, €5 million algae biofuel collaboration known as the FUELGAE mission.
Fuelgae represents a flip of the script. As a substitute of including off-the-shelf carbon seize techniques to algae farming operations, the first focus is to give you new techniques to seize carbon from industrial operations and steer them into an algae biofuel operation.
When it comes to attracting non-public sector companions, Fuelgae is working the United Nations Sustainable Improvement Objectives angle, which casts a large internet for personal sector {dollars}. Fuelgae additionally factors out that the European Inexperienced Deal coverage units a carbon impartial purpose of 2050, with biofuels enjoying a key function in decarbonizing the transportation sector.
“Among various biofuels, algae offer a great advantage because of their growth rates, photosynthetic efficiency, and ability to produce lipids and carbohydrates required for biofuel production,” Fuelgae explains, skipping over the difficulties.
Fuelgae has already recruited 14 companions to show showcase initiatives deploying carbon emissions from two websites in Europe, a biorefinery and a metal mill. This system can be networked with different EU algae initiatives as nicely.
US Has Eyes On The Algae Prize
Issues are additionally heating up right here within the US. That features the macroalgae (aka seaweed) facet. Earlier this yr, the Bioenergy Applied sciences Workplace of the US Division of Power teamed up with the Workplace of Fossil Power and Carbon Administration to launch a brand new $18.8 million funding alternative underneath the title of MACRO, for Blended Algae Conversion Analysis Alternative.
Realistically, the staff notes that macroalgae “are underutilized and are difficult to convert due to their variability, unique chemical make-up, and storage instability.” Nonetheless, the payoff could be important.
“Overcoming these conversion challenges will help build algae biomass supply chains, accelerate their demand, and ultimately, drive the U.S. bioeconomy by enabling greater volumes of sustainable aviation fuel (SAF) and carbon dioxide (CO2) conversion to algae,” they word.
In addition they word that seaweeds and different “wet waste” assets play a big function within the 2050 decarbonization purpose set for the US by the Biden-Harris administration, with a specific emphasis on supporting sustainable aviation fuels and the rising bioeconomy normally.
The chosen awardees will probably be introduced in September, with one matter space devoted to extra R&D. That will sound like a child step, and it’s, however the Power Division staff factors out that this a part of the funding spherical addresses “gaps in storage, mobilization, and conversion of readily available algae, including offshore farmed seaweeds, seaweed wastes, and blends of seaweed with other waste algae,” amongst different need-to-know areas.
A second matter space is extra aligned with the Fuelgae timeline. Awardees on this class will give attention to algae farming (micro or macro) with an help from carbon dioxide emissions from energy crops and different industrial sources.
Extra Algae For Sustainable Meals Programs
In an fascinating twist, the second matter space is targeted on value-added merchandise except for algae biofuel.
“Applications are sought that utilize anthropogenic (e.g., fossil fuel derived) CO2 emissions, including concentrated CO2 supplied from DAC technologies, in the cultivation process and then convert macro- and/or micro-algae into low-carbon agricultural applications or bioproducts such as animal feed,” the Power Division explains.
The appliance course of closed final month, and a complete of eight awardees will probably be introduced in September. In the meantime, the Power Division is already funding one such mission, which is able to lead to fish meals created from microalgae if all goes in response to plan.
Alternatively, the bar has been set fairly low at animal feed. Some algae traders have already spurted far forward of the sphere. Within the newest information on that rating, earlier this yr a consortium composed of the Singapore-Netherlands startup Sophie’s Bionutrients and the New Zealand microalgae agency NewFish, together with analysis establishments within the Netherlands and New Zealand, introduced a brand new collaboration on GMO-free, dairy-free various meals for people.
In a press assertion, the companions clarify they’re a part of a “global mission to develop microalgae as the base for sustainable nutrition and novel food products that eliminate animal suffering and promise an ecological footprint far superior to that of intensive industrial farming.”
“This partnership will serve as a starting point for deeper global collaboration between the parties and will accelerate the microalgae foods and nutrition industry. We are solving a global issue, which requires a collective solution,” mentioned NewFish common supervisor Hamish Howard.
The Algae Biofuel Market Is Flexing Its Muscle tissues
Circling again to algae biofuel, it seems that persistence is starting to repay. On April 3, the agency Analysis and Markets famous that globally, the algae biofuel market “has experienced remarkable growth.” In addition they credit score North America with selecting up a management function.
“The global shift toward sustainability is a key driver in the global algae biofuel market, driving both innovation and investment in this renewable energy sector,” Analysis and Markets explains. “This transformation is motivated by the urgent need to address climate change, reduce reliance on fossil fuels, and create more sustainable energy solutions.”
The large query is whether or not or not the algae biofuel market can maintain progress, as forecast by Analysis and Markets. If it does, that would definitely vindicate the Power Division.
For that matter, some US researchers are already envisioning algae biofuel farming on Mars. You probably have any ideas about that, drop a word within the remark thread.
