We have ‘Big Oil’, so why not ‘Big Biopower’? (And what does it mean for the solar and wind industry?)
Enter Adage (Chadds Ford, PA) a new joint venture biomass development company formed by nuclear energy vendor AREVA (Bethesda, MD) and electrical utility giant Duke Energy, N.C).
ADAGE will be focused on enabling green biopower energy solutions for the US electricity market tapping waste organic materials like wood chips.
BioPower via Waste to Energy?
Bio energy means many things. While most people think of biofuels from corn, this first generation ‘food crop’ source is not the future of bioenergy. (Don’t get distracted by corn ethanol, bio energy potential is vast!)
Real bio energy growth is likely to come from a combination of plant, algae/bacteria and organic waste sources. A leading ‘non-food’ crop resource is Jatropha, but biofuels can also use enzyme supported systems (cellulosic ethanol) or applying chemistry to create hydrogen rich fuels from waste streams.
Bio energy also uses the higher conversion efficiencies of carbon-eating algae to produce biodiesel, and hydrogen-breathing bacteria for electricity.
Organic material supplies would come from regional industrial suppliers with excess wood wastes and ‘forestry operations within about a 50-mile radius around the biomass power plant.‘
So Adage will develop projects in regions with well established industries that can deliver steady streams of organic waste. [And it is important to note that waste to energy strategies have an obvious limitation based on amount of waste available.)
‘Combustion() based BioPower, but Carbon Neutral‘
Today, electricity is produced by burning things. The energy released from burning off carbon-hydrogen bonds leads to steam that spins turbines to produce electricity. Adage’s form of ‘waste to energy’ is in essence – carbon neutral.
Adage will be burning (I am verifying this claim. See comment section) organic material (trees / plant material) resulting in CO2 emissions, but that carbon is recaptured by trees and plant life. (Assuming more trees, crops and plant life are replaced!)
It might sound sketchy, but the burning of biomass waste is much better than releasing the massive amount of energy of coal that have been locked away in ground deposits for millions of years. So it is a step forward!
Despite its carbon neutral approach, Big BioPower might be a hard pill to swallow for eco-purists which favors non combustion power generation of solar and wind. The prospect of ‘Big BioPower’ could bring an unexpected twist for solar and wind producers looking to tap ‘renewable energy’ credits for state utilities.
More on Big Biopower’s opportunities and challenges ahead for solar and wind
Algae and bacteria can be used to capture energy from carbon-rich waste streams from coal plants, agricultural farms, food processing facilities, wastewater treatment plants and - yes, catfish farms.
Arizona-based PetroSun Biofuels (Subsidiary of PetroSun) has announced plans to integrate algae systems with catfish farm ponds for commercial algae-to-biofuel operations. PetroSun Biofuels is quickly becoming a biofuel startup with global reach. It already operates an open algae biofuel farm in Texas, has licensed its technology outside of the US, and is working to launch operations in China.
PetroSun BioFuels and Biomass Partners have identified up to 80,000 acres of catfish ponds within the state of Mississippi that hold the potential for commercial algae bioenergy systems. Based on PetroSun's annual potential production rate of 2,000 gallons per acre, the existing 80,000 acres of ponds would produce 160 million gallons of algal oil annually for conversion to biodiesel. The remaining algae biomass (e.g. fatty acids) could be processed into ethanol, animal feed, fertilizer and other biomaterial products.
PetroSun is working to secure land surface rights and existing farm ponds located in Alabama, Mississippi, Louisiana and Arkansas but has not yet announced dates for planned production facilities.
2008 was a big year in energy and one that we could very well look back upon as the platform to the not so distant future of energy. Much has happened. To help you make sense of it all, we here at The Energy Roadmap have sifted through our bookmarks, Google Notebooks, back of the napkin lists, Twitter searches, interview transcripts, and RSS feeds to come up with the top 10 energy stories that will have an impact on our culture, society, and lives.
Algae bioenergy is based on a powerful idea that is still just off the radar of mainstream conversations on the future of energy. We can 'grow energy' by tapping 'carbon eating' algae that create usable forms of hydrocarbons for fuel or biomaterials.
The idea seems strange and futuristic, but it actually describes our past. We already tap the power of bioenergy everyday. Coal is ancient plant life, and oil is (likely) ancient microbes that lived in shallow oceans. Both plants and microbes fuse hydrogen and carbon bonds using the power of sunlight. But algae is a more efficient in that conversion and results in a higher hydrogen to carbon ratio. That means a cleaner burning fuel!
Everytime you turn on the light (via coal power plant) or drive a car you are capturing the energy released from carbon-hydrogen bonds form by ancient biology. Now energy visionaries are looking at how we can tap the same processes today to 'grow energy' without relying on food crops like corn or soy.
This week The Takeaway has been running Power Trip a series of programs on the future of energy. Earlier this week, Host John Hockenberry visited algae biofuels company Bionavitas in Seattle, WA.
The US Departments of Energy (DOE) and Agriculture (USDA) have released its National Biofuels Action Plan [4.9MB] detailing Federal agency and private partnership efforts to accelerate the development of ‘a sustainable biofuels industry’. While first generation biofuels such as corn ethanol have been under tremendous scrutiny in recent months, the US agencies appear to be positioning themselves to offer measurably sustainable biofuel resources that will rely heavily on next generation resources (e.g. non-food, waste biomass) and biologically driven conversion processes. [Principles outlined in Biofuel Plan Factsheet]
The official word – We have Plan
“Federal leadership can provide the vision for research, industry and citizens to understand how the nation will become less dependent on foreign oil and create strong rural economies,” USDA Secretary Schafer said. “This National Biofuels Action Plan supports the drive for biofuels growth to supply energy that is clean and affordable, and always renewable.”
Translation: We are hedging our bets on the future of bioenergy!
Looking beyond the rhetoric of energy security, and clear tip of the hat to rural agricultural politics and the influence of mainstream agricultural players, target-based plans do secure federal funding streams for next generation bioenergy solutions. And there are significant funds headed towards innovative start up companies that could develop game-changing bio industrial applications. These start ups could ease our reliance on traditional petrochemicals for making fuels, fertilizers and raw materials processing.
But the key takeaway might be that the DOE is hedging R&D investments on traditional chemical biofuel refining processes (traditional catalysts) by also advancing potentially lower cost biological conversion processes (enzymes/algae).
To develop low cost cellulosic biofuels from non-food biomass feedstock, the agency announced $12.3 million contract with bioenergy startup Novoyzme. The company will be contracted to develop enzymes capable of breaking down strong cellular plant walls under its named project DECREASE (Development of a Commercial-Ready Enzyme Application System for Ethanol).
According to Novoyzme, the company has confirmed plans to launch the enzymes required for commercially viable production of ethanol from cellulose by 2010, midway through this contract, with plans to reach an enzyme cost target that is even further reduced by 2012. But there is still rural politics infused as the primary feedstock is expected to be leftover corn biomass waste.
A group of researchers from Boston College and MIT have created a new catalyst that could reduce the negative environmental impact of hydrocarbon or ‘petrochemical’ derived materials found in everyday products.
[Don’t run away! Big words, but simple concepts!]
The new catalyst is used in a very common and energy intensive process known as olefin metathesis. Just think of olefins as simple carbon and hydrogen packets (image of ethylene) that are used to make more complex chains that form the backbone of materials used in everything from cleaner fuels, soaps, bags, to pharmaceuticals. The process, ‘metathesis’, simply means transforming the order of AB + CD into AD +BC
How does a simple packet of hydrogen and carbon vary so much in
different industry applications? In the most simple terms – the difference between a ‘good’ compound for people and the Earth, from a ‘bad’ compound is the use of additives (other elements) and the shape of the molecule chain (polymers). These variations make materials more or less reactive to things like light, water, and heat. It also makes it more or less soluble, biodegradable or toxic. The goal is to create compounds that break down into non-toxic elements that do not harm ecosystems. The more precise we are in building key polymer materials, the less harmful waste we produce.
Why is this important to the future?Another step towards ‘greener’ hydrocarbon materials
The BC/MIT catalyst will help to reduce the waste and hazardous by products of this massive industrial chemical reaction as we try to make chemistry more ‘green’ and environmentally friendly.
“In order for chemists to gain access to molecules that can enhance the quality of human life, we need reliable, highly efficient, selective and environmentally friendly chemical reactions,” said Amir Hoveyda, Professor and Chemistry Department chairman at BC. “Discovering catalysts that promote these transformations is one of the great challenges of modern chemistry.”
The idea is simple. Tap the power of biology for energy production, energy conversion, energy storage and carbon utilization.
The most common forms of energy (coal and oil) arrived here via ancient biochemical pathways. Coal is ancient biomass likely ferns. Oil is likely ancient micro organisms that lived in shallow seas. In both cases life (biology) used the power of sunlight to re-arrange carbon, hydrogen and oxygen. (Algae and bacteria are better converters compared to plants and also result in higher hydrogen to carbon ratio.)
Today, we use this ancient bio energy to power our world. When we drive our cars we are burning chemical bonds created by algae and bacteria.
So instead of extracting this ancient bioenergy, why not grow it here?
Growing Energy using Algae and Bacteria
Today there are dozens of bio energy startups tapping the power of plants, algae and bacteria to ‘grow energy’.
The most disruptive idea being explored by startups is to channel coal stack carbon dioxide emissions into water filled bags with carbon-eating algae which can re-purpose carbon and hydrogen into fatty acids which can be used to create liquid biofuels.
‘Growing Energy’ Meme Background
One of the turning points of the ‘growing energy’ meme was a talk delivered by Juan Enriquez at the 2007 T.E.D. Conference. This 18 minute talk is a wonderful first step in answering the question – ‘why biology’?
has long been considered one of the most forward looking technology visionaries in Silicon Valley. He is also one of many Silicon Valley investors becoming very interested (and invested) in the convergence of biosciences and the energy industry. Jurveston sits on the board of Craig Venter’s new company Synthetic Genomics which hopes to tap the power of synthetic biology for energy production.
In this 6 minute ZDNET presentation clip from AlwaysOn GoingGreen conference held on September 10-12th, 2008, Jurvetson explains the implications of accelerating changes in biology, genetics, and synthetic biology to the future of energy.
Accelerating changes in biology and cleantech
The future of biology is likely to converge with other industries like energy within the next 10-20 years.
Bio energy is very complicated subject with enormous potential to change how we produce biofuels, hydrogen and bio-material feedstocks. But it is also in its early ‘hype’ stages of development and we need framers who can eloquently describe how these changes in biology and genetics might someday change energy.
Fortunately for us – Steve Jurveston is one of those visionaries who can explain this convergence of biosciences and energy.
A research group led by Montana State University Professor Gary Strobel has found a fungus (Gliocladium roseum) inside a Patagonia rainforest that produces hydrocarbon chains similar to diesel fuel or “myco-diesel”.
Why is this important?
Our world is powered by capturing the energy released from carbon-hydrogen chains from wood, coal, oil and natural gas. This chemical energy was formed by ancient biological processes via plants, algae and bacteria. But what if fungi could do the same thing?
If we expect to move beyond an extraction economy that taps ancient bio energy via coal and petroleum, we need to find substitute sources of energy producing systems. Rather than look at energy conversion via plants (e.g. corn), researchers are looking at more ancient forms of life to find the most efficient metabolic systems involved in energy conversion.
When can I put myco-diesel in my vehicle?
There is still a very long way to go before we can develop energy roadmaps and forecasts for fungi derived fuels. For now, smart money is on cellulosic and algae derived biofuels. This is an important discovery, but we have no applied evidence that it could easily scale to produce large amounts of usable forms of liquid fuels at a low cost. But this is an important first step and a significant discovery around the fundamentals of bioenergy!
Could coal emerge as the biggest energy story of 2009? We think so!
Coal is likely to become President elect Barack Obama’s first great energy policy challenge- as evidenced by the coal industry’s ‘Congratulations’ ad on CNN.com
Why coal? Big Story for 2009: Problems with ‘Big Grid’
As prices at the pump drop in response to the global economic slowdown, we can (sadly) anticipate less media and public attention to the long term challenges of oil. Fortunately we have a problem of equal magnitude- an aging, some say failing, electric utility grid run by large enterprises who are already rethinking their changing role in the next century.
There is a short list of big issues for ‘Big Grid’ – building a 21st Century ‘Smart Grid’ around software and storage, integrating utility scale renewables (solar, wind, biomass waste), addressing regulatory challenges of carbon emissions, and working with private sector entrepreneurs who are advancing technologies that could disrupt long-held pricing structures and operating principles of our antiquated grid.
Today, we cannot talk about the future of utility grid energy or global energy and climate issues without confronting the challenges of coal. ‘Clean Coal’ refers to various methods of capturing energy from coal while reducing the amount of pollutants. Critics argue that coal can never been ‘clean’, while supporters of ‘cleaner’ coal argue that we must develop cost effective strategies that can reduce the impact of coal being burned in the US, China and around the world.
There is an echo chamber of cynicism around the topic of corn ethanol. Unless you are a corn farmer or part of the ethanol lobby, evergyone agrees that this is not a sustainable path.
So the world is moving forward. The conversation is now focused on next generation bioenergy solutions that avoid the problems of 'crop' based biofuels.
The US government has placed a ceiling on future growth for corn derived fuels, and now the Obama administration has announced up to $25 million in funding for research and development of technologies and processes to produce biofuels, bioenergy, and high-value biobased products.
The money will fund projects related to: Feedstocks development; Biofuels and biobased products development; and Biofuels development analysis.
What is happening? 'Biology' is coming of age as a driver of industrial and energy applications.
Why 'Bioenergy'has more to do with Bio-Industrialism than Farming
Bioenergy visionaries with algae and bacteria aren't the only players in town trying to corner the market on the 'future of biofuels'. We cannot forget the Chemists.
Biofuels are expanding along two paths- one is based on chemical engineering, the other on biological processes.
Chemistry vs Biology We can create biofuels by applying chemical engineering processes (e.g. ethanol via fermentation, or biodiesel via transesterfication) with high reliability and scale, but usually at a high cost.
Or we can let Mother Nature do the work. Biology taps the power of algae and bacteria that contain special enzymes that reorganize molecules into a format that can be used to make biofuels, or converted into electricity via a fuel cell.
Biology could offer lower cost and turn carbon emissions into a feedstock, but first we must overcome challenges of scaling up volume production, and the unpredictable nature of biomolecular systems.
Wisconsin Focuses on Path of Chemistry For now, chemical conversion is the more immediate opportunity and fits within the current paradigm of processing energy and materials feedstocks. And engineers are working to overcome the challenges to reduce the number of steps, and facilitate reactions at a lower temperature with non-toxic, abundant resources.
Now scientists at the University of Wisconsin-Madison have developed a two-step method to convert cellulose into a biofuel called DMF. Professor Ronald Raines and graduate student Joseph Binder highlight the two step process: First, they convert the cellulose of untreated biomass into the "platform" chemical 5-hydroxymethylfurfural (HMF) which is used in 'a variety of valuable commodity chemicals'. Generally HMF is made using processed glucose or fructose rather than raw biomass.
Step Two: Creating a New Biofuel with Gasoline Qualities
