Pig Urine: The Latest Substitute for Fossil Fuels

Michael Kanellos: September 8, 2008, 5:55 AM
Copenhagen--Yes, you can make plastic forks out of it. Agroplast, a green chemistry start-up in Denmark, has figured out a way to produce plastics, fuel additives and other products from the urine of barnyard animals. The system automatically collects the urine, separates out the urea, and then prepares the urea for a useful life beyond the farm. Chemical manufacturers now use urea in a variety of products, but it is largely artificially produced by cracking natural gas, or methane. That top picture you're looking at is a solid plastic bottle made from urea from the farm-collected urea. That stuff in the white dish is what urea looks like when solidified. It sort of has a texture like Crisco, in case you were wondering. Getting urea straight from the farm has a number of benefits, says Chairman Jes Thomsen. For one thing, you're not digging up buried fossil fuels to make chemicals. The urea comes from a renewable process. Two, pig waste product is now a major problem for farmers. In the U.S., farmers have to pay collectors around $86 per pig per year (not counting subsidies) to dispose of the waste. Pigs produce a lot more waste than can be used as fertilizer. Third, there are a lot of pigs out there. the pigs in the U.S. produce enough urine to cover the urea needs of the states. The U.S. now imports 50 percent of its urea. The pig population in Canada, the U.S. and the six largest European countries comes to 200 million pigs. If you collected four percent of that urine, you're talking 2. 5 million tons a year. Fourth, it's cheaper. Thomsen estimates that the company's products could cost half to produce as those produced with natural gas, once Agroplast hits volume. Farmers in Europe also get credits for employing high tech solutions like this. Fifth, you could drastically cut down shipping costs and fuel consumption. Natural gas comes from the Middle East and Russia. "But s... is everywhere," said COO Bent Hundrup. Here is how it works. The company has a collection system that lets the waste from pigs fall through a grate. Once beneath the grate, the urine is rapidly separated from the manure. If the separation isn't accomplished quickly, the urine turns to ammonia, said Thomsen. Ammonia is actually the source of the terrible smells on farms (chalk up another benefit.). Agroplast then removes the yellow color, water and other materials. It's a tricky process. "Urea is a small molecule," Thomsen said. The company's first product, coming next year, is AgroBlue, which is sprayed into the tailpipe of diesel cars and trucks to eliminate NOx fumes. It is a mixture of urea and water. It is chemically identical to Adblue, a formula produced right now out of urea-produced methane. The EU mandates these sort of chemicals and the U.S. will have similar regulations soon. (That's Jes holding the bottle of AgroBlue, by the way.) Plastics will follow. The AgroBlue product was simply easier to produce, explained Hundrup. Bioplastics are clearly moving beyond corn. University of College Dublin is experimenting with a way to convert difficult-to-recycle plastic into a biodegradable form of plastic with the help of bacteria. The company does not sell the equipment. Instead, it installs a system on large farms (or near groups of smaller farms) and then charges farmers to eliminate their waste, albeit in an economically advantageous way to the farmer. In some cases, the company may even offer to take waste away for free as a way to build market share. Agroplast then processes the chemicals and sells them The company has proven the technology works in prototype plants in the U.S. and Europe and is currently seeking funding to build commercial-sized plants. A single module of their technology would serve 25,000 pigs and cost $2 million dollars. And once they do get into mass manufacturing, the plants will probably become one of the more popular and memorable third grade field trips around. There's another benefit.

Biomass Energy: the Global Potential in Numbers

Michael Kanellos: September 5, 2008, 6:06 AM
Copenhagen—Biomass is the original source of energy for humanity (It’s lasted far longer than bear skins, the original insulation) and still one of the most pervasive. But can it continue to scale? Yes, says Claus Felby of the University of Copenhagen, but we’ve got to figure out better ways to harvest it. Globally, the amount of energy contained in the biomass produced by plants annually is five times larger than our current energy consumption, he said in a lecture at Copenmind, a technology transfer conference that took place this week. Put another way, that's 5X our energy consumption in indirect solar power. Right now, though, the world only gets 10 percent of its energy from biomass. 'We need to increase it by a factor of three to four," he said. "If we cannot supply enough sustainable biomass, we cannot develop a sustainable economy. Economic growth will depend on ecological growth." Two-thirds of it could be used for heating and the other 1/3 could go to transportation. Does the land exist to expand like that with existing crops and current technologies? No. He did an examination of Denmark's own land capacity. If you wanted to run 10 percent of Denmark's vehicles on biofuels, you would need 1.5 million hectares. Denmark only has 2.5 million hectares under cultivation. So what can we do? 1. Cross-breed new types of plants. 75 percent of a plant's mass is sugar. We need to develop plants that will yield the types of sugars that are more easily extracted and converted to fuel. 2. Stop eating so much, particularly meat. This could have the biggest dent. Right now, only 1 percent of cropland globally is dedicated to biofuels. Close to 70 percent are used to grow feed for animals. 3. New types of power plants. In 2009, Europe's first combined biomass/biofuel power plant will start producing. This plant, located in Denmark, produces ethanol and power, and the waste heat is captured to help run the plant. It's been in development for seven years. 4. Better farming techniques. Felby created an economic model to determine how much could be saved (in fertilizer, carbon credits etc,) if farmers optimized production with multicrop growing and other techniques designed to reduce energy consumption. He concluded that efficiency techniques could save 1359 Euros per hectare per year.

A New Bioplastic, Made by Bacteria

Michael Kanellos: September 2, 2008, 6:36 PM
Copenhagen—The employee of the decade in green tech is scum. University College Dublin (UCD) has come up with a way to recycle old plastic bottles and containers with microorganisms. The end result—the thing that comes out of the bacteria’s digestive system--is a new piece of plastic. The difference, however, is that the plastic that comes out of the process is biodegradable. It can go safely into a landfill and will disappear over time, said Kevin O’Connor, the lead researcher on the project during a presentation at Copenmind, a university tech transfer conference taking place this week. If the process can be brought up to an industrial level, it could help the world get rid of the nation-sized mass of plastic that humanity has generated. Right now, there are two general ways of dealing with old plastic. Some countries, like England and Ireland, ship it to other countries after doing the green thing and recycling. Plastic bottles have a low recycling value; hence, a lot of the plastic ends up in landfills forever. (But the Irish are big into recycling—a 15 cent tax on plastic bags dropped their use by over 99 percent, O’Connor said.) The other method to “recycle� plastic is to burn it. Sweden, Switzerland, Germany and other countries practice it. It yields useable energy, but it’s not the cleanest practice in the world either. UCD’s process works like this. Polypropylene (plastic) is cooked until it turns into a styrene oil. The oil is then fed to microorganisms, which metabolically turn it into globules of fatty acids. When 60 percent of the bacteria consists of those fatty acids, the microorganism is split open and the harvested fatty acids are converted to a biodegradable plastic. See why bacteria make such good workers? Try to do that to your new hire from Cal State Fullerton and the first thing he’ll do is file a worker’s compensation claim. It’s good plastic too. The glass transition temperature—the temperature that makes it brittle—is a low minus 43.3 degrees Celsius, so it’s freezer safe. You can heat it to 278 Celsius. “But it will degrade in a compost heat at 32 degrees because the microorganisms (in the landfill) release enzymes,� he said. Industrial microbiology is the basis of a number of other start-ups, including Cambrios (microbes making industrial chemicals) and AgraQuest (biopesticides). Melting the plastic into an oil requires energy. The overall balance, however, is better than if you made a second, separate bottle, O’Connor asserted. A kilogram of plastic yields 350 grams of new plastic. The missing oil goes to the microorganism: they feed off the oil to grow. The group has filed for a few patents. Next year, it wants to move out of the lab and do a multi-kilogram recycling center with a large waste company. Keep your eye on Ireland in cleantech and advance science, by the way. For years, the Irish tech industry primarily concentrated on serving as an outsourcing destination for multinationals. But in about 2000, the government—realizing that Ireland was no longer a low-cost center—began to invest in technology transfer center and incubators. The pitch made to scientists is straightforward. Unless researchers can’t come up with interesting commercial applications, funding may get cut during austerity times, Pat Frain, who runs NovaUCD (the school’s incubator) told me earlier this year. Plus, you might become incredibly wealthy. Other incubation centers in Ireland are working on ocean power, semiconductors and material science. (See this masterpiece of cinema for more.) Another interesting project at UCD: BiancaMed, which has a wireless device that can tell you what happens to your body while you sleep. Whether or not the incubator program ends up creating successful start-ups, however, won’t like be known for another five years.

Toyota Plugs Lithium Ion Batteries, Reluctantly

Michael Kanellos: September 2, 2008, 6:39 AM
Copenhagen—Toyota and lithium just don’t mix. Masatami Takimoto, executive vice president for the technology department at Toyota, acknowleged during a presentation at Copenmind, a technology conference taking place here this week, that the Japanese auto giant will inevitably put lithium ion batteries in some types of cars. Toyota, for instance, will probably put lithium ions into commuter cars and will also likely use a lithium ion battery in its plug-in hybrids. In fact, the company will in the near future send out lithium ion batteries to those testing the plug-in Prius. Right now, those plug-in Priuses contain two regular Prius batteries, which cuts the all-electric driving range down to around 13 kilometers. Challenges, though, persist with lithium-ion batteries, he said. They are expensive. They can’t drive cars very far and they weigh a lot, which in turn hurts mileage. Thus, enthusiasm is tempered. “Lithium ion batteries will probably be used in vehicles, but we still have problems,� Takimoto said. “We do think it’s appropriate to use lithium ion batteries in commuter cars.� And don’t expect an all-electric car with lithium ion batteries, or any kind for that matter, for a while. Batteries don’t have the energy density that can compete well with liquid fuels or even fuel cells. “We at Toyota believe that plug-in hybrids are the most practical way for an ordinary vehicle to take advantage of electricity,� Takimoto said. Take a look at the shot of his PowerPoint slides from the conference. That little bar at the left near "inferior"? That’s the energy density of lithium ion batteries. Next over is combustible hydrogen (not fuel cells) and compressed natural gas. and next beyond that are the liquid fuels. Takimoto also pointed out that all-electric cars were a tough sell in the past. In the 90s, the company put out an all-electric version of the RAV4. It didn’t sell well because customers were concerned about price and range. Despite all the skepticism surrounding hydrogen fuel cells, he said that the concept still has a future. Take a look at this second power point slide. The brick walls represent the technological and other hurdles that will need to be overcome for a particular technology to succeed. For fuel cells, the biggest challenges are figuring out ways to make hydrogen cheaply without generating carbon dioxide. (Now, most companies make it by cracking methane at high temperatures, which releases large doses of CO2.). Transporting hydrogen will also take work. But look at the size of the barrier. It’s a lot smaller than the one for electricity. A hydrogen fuel cell car being tested by Toyota gets 560 kilometers on a tank of the gas. “We should assume that electricity and fuel cells will be necessary,� he said. Cars, particularly commuter cars, will also get smaller. He showed a picture of the iQ, a Smart-car sized commuter vehicle that can fit four passengers coming soon. It’s less than three meters long. (How do they get four adults in? The seats are really, really thin, like outdoor furniture). The other interesting point about his slides is the projection for liquid fuel. In short, they are going to be around for a while. Diesel and gas will naturally have to be cut down. The automotive industry can’t survive unless we do something about dwindling supplies, air pollution and CO2 emissions. He noted that 60 percent of the NOx gases in Japan come from diesel transportation, and diesel isn’t popular in Japan. To that end, Toyota is experimenting with cellulosic ethanol, flex fuel vehicles, and even looking at things like natural gas to liquids (GTL) and coal to liquids. The hybrid, though, still rules at Toyota. As of August, the company has sold 1.6 million hybrids to date. These cars have cut fuel consumption worldwide by 2.9 billion liters and carbon dioxide emissions by 7.5 million tons. The company wants to be selling a million hybrids a year in the 2010s. So far, Toyota has come out with 12 models of hybrids and will have a hybrid option in all of its lines of cars in the 2020s, he said. These figures include Toyota’s diesel hybrid buses.

From Debs to Estrin and Palin

Eric Wesoff: September 2, 2008, 4:37 AM
It’s Labor Day week, so I’m going to quote Eugene V. Debs. Debs doesn’t get quoted much or even remembered much so I’d like to do it.
Eugene V. DebsIn this country – the most favored beneath the bending skies – we have vast areas of the richest and most fertile soil, material resources in inexhaustible abundance, the most marvelous productive machinery on earth, and millions of eager workers ready to apply their labor to that machinery to produce in abundance for every man, woman, and child – and if there are still vast numbers of our people who are the victims of poverty and whose lives are an unceasing struggle all the way from youth to old age, until at last death comes to their rescue and lulls these hapless victims to dreamless sleep, it is not the fault of the Almighty: it cannot be charged to nature, but it is due entirely to the outgrown social system in which we live that ought to be abolished not only in the interest of the toiling masses but in the higher interest of all humanity…
Eugene Debs, labor leader, five-time Socialist Party candidate for president, dubbed "the most dangerous man in America," said this just before being sentenced to 10 years in prison for speaking words powerful men did not like, in the midst of a wrong, stupid war that never should have been fought. Anyway speaking of wrong and stupid, and ignoring the Republican Vice Presidential selection for now, lets’ talk about Judy Estrin’s new book, “Closing the Innovation Gap.� Estrin was the CTO of Cisco, whose innovation has long been the ability to acquire and integrate other people’s technology, which is certainly a skill, but not exactly the innovator’s mojo that makes Silicon Valley tick. Estrin has credentials – she has founded successful small companies and serves in the boardrooms of successful big companies. I spent an hour at Kepler’s skimming her book and another session reading her book on Amazon. But despite the obsequious blurbage from local geek-celebs McNamee and Cerf, I didn’t really get her point, other than trying to sell mediocre management books. She provides anecdotes and case studies from P&G, Pixar and HP Labs, amongst others, but it smacks of someone who has spent too much time in the Disney and Cisco boardrooms and has forgotten her startup garage roots. Because innovation is alive and well in Silicon Valley, on Route 128 in Boston, in the Pacific Northwest, in Colorado, in Austin, and in tech clusters all over this nation. It’s just not where Estrin is looking for it. Maybe she’s looking for it in networking companies. Wrong place, I guess. She speaks of Venture Capitalists not willing to take risks. But in greentech and  renewable energy markets, VCs are tearing it up. Cool Earth Solar uses balloons to focus sunlight – it’s a longshot but VCs are bankrolling it. SolFocus, A CPV startup, really was founded in a garage. VCs have not been shy about funding every algaepreneur (Thanks, Ed.) like Solazyme or Greenfuel or Livefuels with a new pond scum strain and the potential to create biofuels from the stuff. If anything, these VCs seem to be attracted to crazy ideas. Electric cars in really strange configurations are being backed all over the U.S. There have been at least 150 new solar power companies funded by VCs in the last three years.  That’s 150 new companies. Just in solar. (Contact me if you’d like that list). Estrin also talks about impatient investors and and short-term mentality. She’s wrong again. Silicon Valley investors are investing in energy firms, knowing full-well that the gestation period for a solar firm or a biofuel firm is a long time. It’s not a software company where you lock 20 coders in a room with an espresso maker, a foosball table and 10 cases of Ramen noodles. These investors know it’s going to take a lot of investment and a long time to make a real energy company. Nanosolar was founded in 2002 and received its first venture round in 2002. It just recently closed another round for $300 million. None of these investors expected a quick turnaround. What thwarts innovation are spineless politicians and the fossilized and corrupt government control of R&D spending. Recent examples are the ITC idiocy from our Congress and Senate. Nancy Floyd of Nth Power and Dave Edwards at VantagePoint could testify to the government’s shortsightedness in sabotaging the American wind industry with an on-again, off-again tax framework. Just ask them. We do need lots more government sponsored R&D. And we need it to be controlled by technologists and entrepreneurs, not policy-hacks and bureaucrats. We need a revamped educational system with an emphasis on science and perhaps a little less creation “science.� (See earlier Vice Presidential citing). Lastly, technology like solar doesn’t always advance because of innovation, it advances because of political clarity and an informed and willful public. That’s the innovation we need.

General Motors Decides on Battery Maker for Volt—Will it Help or Hurt A123 IPO?

Michael Kanellos: August 29, 2008, 5:39 PM
The beauty contest is over. Unfortunately, we don't know the winner. Bob Lutz, chairman of General Motors, said in a press conference in Joliet, Ill. that the automaker has decided on a battery maker for the Chevy Volt, the hotly anticipated plug-in hybrid coming toward the end of 2010. Lutz, however, didn't say which of the two battery makers GM is working with has selected. The money-losing automaker has been working with two vendors: Compact Power, whch is a U.S. based subsidiary of South Korea's LG Chem (Life's Good with Chemicals) and Continental Automotive Systems. Continental has been working with A123 Systems. GM is also an investor in A123. For A123, the Volt contract is a make or break moment. The battery developer filed documents earlier this month to hold a $175 million IPO. It generated $41.3 million in revenue but posted a $31 million loss last year. The company's largest customer right now, Black & Decker, cut back purchases in the first quarter. In all, A123 has raised $132 million. Being part of the Volt contract would give the company the opportunity to drastically grow revenue. The batteries in plug-ins are a lot bigger and more expensive than those in power tools. Consumers and policy makers have also gone bonkers for plug-ins. If GM builds a decent car, it could go a long way toward reversing the company's fortunes. I saw a prototype last year in Los Angeles and spoke to Andrew Farah, one of the chief engineers on the project. GM has clearly taken this seriously and wants to have a hit. It's not a half-hearted effort. On the other hand, if GM goes with brand B, there will be a flurry of people writing the A123 obit.

Algae Oil Maker Solazyme Gets $45.4 Million More

Michael Kanellos: August 26, 2008, 4:51 AM
Solazyme is continuing to move away from the pack in algae oil. The South San Francisco-based company has raised $45.4 million in a Series C funding, according to PE Hub. Investors included Braemar Energy Partners, Lightspeed Venture Partners and Harris & Harris group. The total includes $6.4 million in convertible securities. That brings the total raised by Solazyme, when grants and everything is mixed in, to close to $70 million by some estimates. The company is both one of the oldest algae oil companies (dating way back to the first half of the decade) and one of the most novel. Rather than grow algae in ponds or closed-in water tubes called bioreactors through phototsynthesis, the company has identified species that grow by feeding off sugars in the dark. Solazyme effectively puts these algae and discarded plant matter into kettles and brews up algal blooms. The algae is then harvested for oil. Solazyme also genetically optimizes the natural strains of algae. By eliminating the need for water, Solazyme doesn't have to worry about separating the algae from the water to harvest oil, a big problem. It can also control the growth of algae. The company initially tried to grow algae through photosynthesis but switched. (See further explanation of the company's technology and business plan from founders Harrison Dillon and Jonathan Wolfson in this masterpiece of cinema.) Solazyme also likes to point out that it has made oil, barrels of it, unlike many of the twenty plus algae companies out there today. It also has a development deal with Chevron. The company will also sell oil to the cosmetic industry and likely the food industry. I actually tried some brownies made with algae oil. They were good. The money will be used to scale up their existing manufacturing facilities. (Right now, the company is housed in a building that once served as an ice cream factory.) Critics, though, note that sugar isn't free, and say that the ecomonics of growing algae with water and free sunlight may win out. So we must wait and see The company also isn't the only one working on novel extraction or growing techniques. OriginOil is concocting a system that will force feed algae and then extract oil from the hapless critters with microwaves. Synthetic Genomics, meanwhile, is working on genetically modified algae that will expurgate their own, like sea cucumbers.
