Chinese and EU Clash Over Airline Emissions
Doug Young China’s increasingly contentious trade relations with Europe suffered another setback late last week, when the EU threatened to fine Chinese airlines that were refusing to comply with a new controversial program to reduce greenhouse gases. China responded with its own threat by saying it won’t accept the EU’s planned carbon tax, raising the prospect of a dangerous new trade war. This latest in a recent series of trade conflicts between China and both Europe and the US is developing into a troublesome pattern that could spin out of control, endangering the nascent global economic...

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...
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...
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...
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...
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...
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...
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...
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 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...
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...
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...
OriginOil Renames Product – Will It Help The Business?
by Debra Fiakas CFA Mid-March 2014, OriginOil, Inc. (OOIL: OTC/QB) relaunched its waste water treatment process for shale gas producers. The company’s CLEAN-FRAC and CLEAN-FRAC PRIME products are now called OriginClear Petro. OriginOil is expanding into the industrial and agricultural waste water treatment markets using the product name OriginClear Waste. The company has been toiling away since 2007 perfecting its “Electro Water Separation” process that uses electrical impulses in a series of steps to disinfect and separate organic contaminants in waste water. In June 2014, OriginOil management declared its development stage completed and start of full...
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...
