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...
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...
Three Water Recycling Stocks
by Debra Fiakas CFA The water series continues as we attempt to get arms around the very large market to package, deliver, purify, treat, and recycle water. As the need for water increases with population and economic activity, the use of waste waters has become an imperative. In this post we look at three companies helping to clean up, reclaim and otherwise recycle waste water. Ecosphere Technologies, Inc. (ESPH: PK) has introduced several water solutions that can be used in agriculture, mining, industry, or municipal applications. The company’s flagship Ozonix Technology is a chemical-free system to recycle...
Mantra’s Promise of Innovation
by Debra Fiakas CFA How often do we see the crowd rooting for the underdog? You could hear the cheers for Mantra Energy (MVTG: OTC) last week at the Marcum Microcap Conference in New York City. Mantra is a developmental stage company pursuing technologies to harness carbon dioxide for energy. Of course, the company has no revenue and therefore no earnings. Indeed, its technologies are so unique and as yet at such an early stage some might find them almost fanciful. Yet for some investors, a fanciful underdog is even better than another. Mantra sees itself...
Air Products Goes Operational with Carbon Capture
by Debra Fiakas CFA In October 2009, the U.S. Department of Energy selected a dozen projects aimed at bringing relief to a planet suffocating in a cloud of toxic carbon dioxide emissions. The DOE called the program it’s Large-Scale Industrial Carbon Capture Storage Projects and wrote checks for $575 million out of American Recovery and Reconstruction (ARRA) funds. A little more than a year later the DOE weeded out all but three projects for the second phase of the program. Besides Leucadia Energy (subsidiary of Leucadia National, LUK: NYSE) and Archer Daniels Midland...
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...

OriginClear: Metals out of the Muck
After the worst of the wind and rain had died down from Hurricanes Harvey and Irma, and people began making their way back home, it became apparent that citizens of Texas and Florida would have more worries. The U.S. Environmental Protection Agency disclosed that at least thirteen toxic waste sites in Texas were flooded and damaged by Hurricane Harvey and another forty-one Superfund sites were negatively affected. Legacy contamination includes lead, arsenic, polychlorinated biphenyls, benzene and other carcinogenic compounds from historic industrial processes. After Hurricane Irma over six million gallons of wastewater reportedly flowed out to the coast and...
FuelTech: Pushing on a String of New Orders
by Debra Fiakas CFA Earlier this month Fuel Tech, Inc. (FTEK: Nasdaq) announced the receipt of order for air pollution control systems totaling $2.0 million. The customers are strung out across the U.S., Europe and China, but they all have dirty combustion systems and need to reduce toxic nitrogen oxide (NOx) and carbon dioxide (CO2) emissions or risk running afoul of government clean air standards. These shipments are just the most recent in a string of orders Fuel Tech has won in recent months. In late August 2015, the company received similar air pollution contracts from...
OriginClear Gambles on Marketing Program
by Debra Fiakas, CFA
Last week waste water treatment developer OriginClear (OCLN: OTC/QB) announced pilot projects for rental of its commercial water systems for pool cleaning. The company has several patents to its credit, protecting its innovations. OriginClear has developed a proprietary catalytic process to clean up solids from waste water as well as an oxidation technology to eliminate microtoxins in water. Unfortunately, the company has struggled to extract value from its efforts. OriginClear has yet to report profits. Indeed in the most recently reported fiscal year ending December 2019, revenue of $3.588 million only barely covered cost of goods of $3.217 million, let alone operating expenses that...
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...
Bion: Waste To Dollars
Earlier this week Bion Environmental Technologies (BNET) received approval of a patent for its proprietary ammonia recovery process. Bion’s technology converts livestock wastes into ammonium bicarbonate. Patent protection in the U.S. paves the way for Bion to deliver an environmentally friendly chemical to the market at attractive profit margins.
Ammonium bicarbonate is used for a variety of purposes from leavening to crop additives. It is the fertilizer market that has caught Bion’s attention. The company intends to ‘close the loop’ for the agricultural sector by helping livestock producers economically dispose of waste and then delivering a fertilizer for food crops that qualifies as organic.
It is an attractive...
Greenhouse Gas Management Stocks: Key To A Real Climate Change Portfolio?
There has been a lot written lately about how to turn climate change into an investment opportunity, including on this site. Not all of it is, however, especially useful or relevant. In the worst cases, commentators have ascribed the 'climate change investment opportunity' label to just about any industry out there, indiscriminate of whether or not there really is a strong and direct connection. If you are seriously interested in playing the climate story, you should stay focused on near and medium term opportunities with real and tangible links to what is currently going on with the climate...
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...
Ten Insights into Carbon Policy and Its Implications
On November 27, I attended the National Renewable Energy Laboratory's (NREL) Fifth Energy Analysis Forum, hosted by NREL's Strategic Energy Analysis & Applications Center. The forum focused on carbon policy design, the implications for Renewable Energy and Energy Efficiency. As a stock analyst focused on that sector, I am extremely lucky to have NREL as a local resource: the quality and the level of the experts at NREL and the ones they bring in is probably not matched anywhere in the country, and conferences like these provide priceless insights into what these Energy Analysts are thinking. Why should investors...
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...
