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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
