Boiler Maker in Need of a Shot
by Debra Fiakas, CFA
A reserve split is in the works to keep shares of Babcock & Wilcox Enterprises(B&W) listed under the symbol BW on the NYSE. The stock price of this storied environmental engineering had slipped below the Exchange’s minimum price requirements. Ten shares will be melded into one beginning July 23, 2019.
Reverse merger math alone will not solve B&W’s problems. One hundred and fifty two years in business, B&W has been providing environmental technologies and services for energy and industrial customers since the company’s first boiler was sold right after the American Civil War. The company boasts that Thomas Edison was one of...
Axion Power is Poised to Dominate Energy Storage for Stop-start Idle Elimination
John Petersen After eight years of rarely speaking above a whisper, Axion Power International (AXPW.OB) has found its voice, taken the scientific wraps off its PbC® battery technology and shown potential customers, competitors and investors that it's carrying a big stick and is poised to dominate energy storage for stop-start idle elimination – a cheap and sensible fuel efficiency and emissions reduction technology that's expected to grow at spectacular rates for the rest of the decade as shown in the following forecast of battery demand in vehicles equipped with stop-start systems. In a new white...
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 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...
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...
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...
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...
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...
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...
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...
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...
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...
The Worst Waste
Jim Lane Peter Brown of FFA Fuels, promotes his company these days with the pithy slogan, “Fuels from the Worst Waste Around.” Which of course raises the legitimate question, what is the worst waste, and can we find a use for it? Discussions of worst waste will usually focus on the obvious say, landfill or the odious say, medical or nuclear waste. Toxicity and longevity are typical concerns, and that’s one of the reasons why nuclear energy remains controversial to this day. No Waste in Nature As LanzaTech’s Jennifer Holmgren observed in a recent article by...
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...
While Others Seek to Inject CO2, Airgas Sells It
by Debra Fiakas CFA Just one of the many suppliers of industrial and commercial carbon dioxide, Airgas, Inc. (ARG: NYSE) recently announced plans to build a new carbon dioxide plant in Houston. The press release hit news wires right along with announcements of carbon capture projects and other investments to reduce greenhouse effect from too much CO2 in the atmosphere. In one those strange twists that makes our world so interesting and vexing at the same time, is the fact that we use carbon dioxide all the while we invest wildly to reduce CO2...
