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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
Carbon Capture and Storage: By the Numbers
"We have over 200 years of coal reserves, and we have to/will use them." I have heard some variation of this line far too many times, and I have little patience for it. Here's why: We don't have over 200 years of reserves. The real number for economically accessible coal is less than half that. A square, 100 miles on a side in the Southwestern deserts of the US could meet the electricity needs of the entire nation, if solar energy were converted to electricity at 10% efficiency. There's a lot of desert in the Southwest, and we're...
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...
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...
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...
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...
