BioNitrogen: Valuable Technology, Management Questions
by Debra Fiakas CFA My last post outlined how Bion Environmental Technologies, Inc. (BNET: OTC/QB) is transforming livestock waste into organic fertilizer. Bion is not the only aspiring fertilizer producer. BioNitrogen Holdings Corp. (BION: OTC/PK) was recently patent protection for a process to produce urea from stranded natural gas. Instead of burning off the unwanted gases, oil and gas operators can turn it into an economically viable by-product. There is more than just cash flow at stake for oil and gas producers. Burning off stranded gas increases harmful emission that can lead to penalties in the...

In a new white...
Southern Company’s Carbon Capture Testing
by Debra Fiakas CFA Coal emissions photo via BigStock An electric utility of Southern Company’s size - $38.3 billion in market capitalization - is not among the typical company covered in the Small Cap Strategist weblog. Southern (SO: NYSE) owns and operates six dozen power plants in the southeastern U.S., generating 12,222 megawatts of power from a mix of fossil fuel, hydroelectric, nuclear and solar plant assets. The company earned $2.68 in earnings per share on $16.5 billion in total electric power sales. Sales dipped in 2012...

Praxair’s Long Road to Capturing Carbon
by Debra Fiakas CFA In 2007, industrial gas supplier Praxair (PX: NYSE) teamed up with power plant equipment dealer Foster Wheeler (FSLT: Nadaq) to work on demonstration projects for cleaning up coal-fired electric generating plants. At first the duo planned to pursue clean coal technologies and oxygenated coal combustion systems. The joint press release at the time indicated Praxair’s “oxy-coal’ technology would be applied to Foster Wheeler’s ‘circulating fluidized-bed steam generators.’ The oxycombustion process is one of several proposed methods to capture carbon dioxide from coal-fired power plants. In a retrofit situation, pure oxygen would replace air...
Tetra Tech: Energy Engineer
by Debra Fiakas CFA In the coming years power generators will be under pressure to meet new standards for lower carbon emissions embedded in the EPA’s Clean Power Plan. Each state has to meet a set of standards set by the EPA based that state’s particular circumstances in electrical generation. The carbon pollution limits begin in 2022 and ramp to full effect by 2030. Power generators could meet standards by reducing harmful emissions from existing fossil fuel-fire plants. Unfortunately, that may prove too costly at some of the older plants. It is logical that power generators...
China Everbright Greentech
by Debra Fiakas CFA Investors based in the U.S. need to look far and wide for new stock issues from renewable energy companies. Capital markets activity has slowed in the last couple of years, in part to due to their own success. In reaching new efficiency in energy production, renewable energy companies are generating their own internal capital and are not as dependent upon the capital markets. The Hong Kong market has come to the rescue of U.S. investors with a ‘green’ offering China Everbright Greentech Ltd. is now trading on the Hong Kong Exchange with the...
Plastics from Carbon Dioxide
by Debra Fiakas CFA In the last post, I promised to close out this series on carbon dioxide capture with a note on a third example of Department of Energy funding for innovations in turning carbon dioxide (CO2) into a valuable raw material. Besides changing the chemistry of inorganic compounds and feedstock for biofuel production, CO2 has some potential for plastics. In 2010, the DOE placed a bet of $18.4 million on Novomer, Inc., which is a self-described sustainable chemicals developer. The bet appears to be paying off as Novomer and its partners go into production...
Earnings Roundup: Metals Prices Boost Covanta and Umicore
By Tom Konrad, Ph.D., CFA
You don’t have to own mining companies to benefit from rising metals prices.
This is a roundup of first quarter earnings notes shared with my Patreon supporters over the last week. Waste to energy operator Covanta and specialty metals recycler Umicore are both benefiting from skyrocketing metals prices.
Just as renewable energy and energy efficiency stocks have long shown that investors don’t have to own fossil fuel companies to benefit from rising prices of fossil fuels, recyclers like Covanta and Umicore are showing that you don’t have to own environmentally damaging mining companies to benefit from rising...
Capturing CO2 for Environmental Remediation
by Debra Fiakas CFA In 2009, the Department of Energy (DOE) awarded $17.4 million in funding to a gaggle of companies pursuing practical uses for carbon dioxide. The recipients were asked to kick in a total of $7.7 million. A year later in 2010, the DOE picked six projects to a second round of support totaling $82.6 million. Industrial giant Alcoa, Inc. (AA: NYSE) leads one of the winning groups, including partners U.S. Nels, CO2 Solutions (CST: V or COSLF: OTC/BB) and Strategic Solutions. The DOE gave the Alcoa team $13.5 million to complete a pilot...
A Concrete Proposal
The Economist recently had a story on how the cement industry is beginning to confront the fact that the industry produces 5% of the world's emissions of greenhouse gasses. Carbon dioxide is emitted not only by the fossil fuels used to create the heat used in the creation of cement, and by the chemical reaction in that process. Unfortunately for us, cement is a remarkably useful building material, not least as a structural material which can also serve as thermal mass in passive solar buildings. All the large cement firms: Lafarge, Holcim, and Cemex (NYSE:CX) have joined a voluntary...
Plasma Arcs For Pig Waste
This week MagneGas (MNGA: NASDAQ) announced new work completed toward plans to enter the commercial pork sector with a proprietary manure processing and disposal solution. Management held a meeting with the North Carolina Department of Environmental Quality and the U.S. Army Corps of Engineers to discuss MagneGas technology to treat agriculture waste and the state’s required environmental permit protocols. MagneGas aims to sell to pig farmers equipment based on its innovations.
The company wants to help pig farmers address environmental problems cause by manure accumulation with its proprietary waste sterilization process. Handling pig waste using conventional methods can be costly, but failure to...
The Low Cow-bon e-Cow-nomy
Jim Lane This month in Finland, a team of intrepid researchers herded one thousand European cows one-by-one into a glass “metabolic chamber” to measure their methane emissions, digestion, production characteristics, energy-efficiency, metabolism, and the microbial make-up of their rumens. The Project is known as RuminOmics, but if it had been titled The Truman Show II: When the Cows Come Home, we wouldn’t have been a bit surprised. The Cow Emission Crisis. No Kidding Around. The ultimate aim of the study was to find an optimal, low-emission, high-yield cow, and the team noted in its premise that of all greenhouse...
A Coal Stock…Almost
This morning, I read an article in this week's Economist that summarized well what I've been hearing over the past few weeks: coal is back in fashion with power utilities. As pointed out in the article, on a BTU basis, coal remains the cheapest fuel for thermal generation, an the prospect of high carbon prices is not deterring even European power generators from investing in coal-fired assets. A few months ago, Tom discussed his peak coal portfolio. The long-term perspective is of course critical to keep in mind, and that piece helps putting recent news around...
Phycal Captures CO2 Funding for Biofuel
by Debra Fiakas CFA As part of its program to promote beneficial reuse of carbon dioxide, the Department of Energy awarded a total of $27.2 million ($3.0 million in the first phase and $24.2 million in a second phase) to a consortium led by alternative energy developer Phycal, Inc. (private). According to the DOE website, Phycal is to develop an integrated system to produce biofuel from microalgae cultivated with captured carbon dioxide (CO2). The biofuel is to be blended with other fuels for power generation or as drop-in diesel or jet fuel. It is a bit of...
The EPA’s Carbon Rule: Likely Stockmarket Winners
By Harris Roen Greenhouse gas emissions by economic sector A seismic shift in the power generation landscape is starting to sink in. It has been two weeks since the EPA announced its new proposed carbon rules, one of the flagship efforts of the Obama Administration to address climate change. This shift is meant to move the country in the direction of inevitable changes coming to the energy economy. It is important for investors to know which companies and sectors stand to benefit from the...
