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...
Tetra Tech’s Two-Penny Disappointment
by Debra Fiakas, CFA
Tetra Tech’s (TTEK: NASDAQ) quarter earnings report last week was met with high drama as traders reacted with surprisingly vehement disappointment over the recent financial performance of the engineering and technology business. The company’s stock price gapped down in the first day of trading following the announcement, falling through a significant line of price support. The shares continued to fall and finished the week at a price not seen since mid-April 2017 before the stock began its recent drive higher.
The drama unfolded after Tetra Tech reported net earnings of $0.52 per share on $498 million in total...
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...
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...
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...
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...
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...
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...
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...
What Shouldn’t Be in a Green Energy Portfolio
The London Accord took a look at what portfolio theory would suggest as the most effective ways to address Climate Change. Knowing which technologies don't make the cut is at least as useful as knowing which technologies do. Tom Konrad, Ph.D., CFA I recently looked at a paper from the London Accord which used portfolio theory to recommend the best mixes of technologies to deliver different levels of carbon abatement. The most useful technologies to achieve the needed levels of carbon abatement were Forestry, Hydropower, Biofuels, Wind, Efficiency, and Geothermal. I suggested stocks that investors might consider to invest in...

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...
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...
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...
Kadant: Will Investors Clean Up With This Bargain Green Stock?
Everybody likes a bargain. Investors really like a good cheap buy. A review of our four alternative energy industries revealed three stocks trading below industry average multiples of forecasted earnings. This is the second article in the series, thee first looked at Ormat (ORA:NYSE). A couple of weeks ago shares of Kadant, Inc. (KAI: NYSE) registered an particularly bullish formation - at least from a technical standpoint. A ‘triple top breakout’ was formed in a point and figure chart, suggesting demand for the stock outpaces supply. Given the new momentum that has developed, the stock could reach...
