A new scientific analysis published today in Science, urges a focus on methane and soot (black carbon) emission reduction to deliver the quickest and greatest range of benefits – ranging from improved human health to increased crop yields.

The major reason for focusing on reduction of these particular greenhouse gases (GHGs) is that methane and soot have a significantly stronger greenhouse effect than carbon dioxide (CO2), but remain in the atmosphere for a much shorter time period. Therefore a reduction today means a rapid effect in “….weeks or months, not decades or centuries,” according to atmospheric physicist Veerabhadran Ramanathan, of the Scripps Institution of Oceanography at University of California, San Diego.

Even better news: out of about 400 emission control measures studied, the team of researchers noted that just 14 of those steps generated 90% of the benefits. Third on the list is capturing methane — also known as biogas, from landfills in the U.S. and China. Other steps on the “top 14″ list involve capture of methane from other sources, such as coal mines or petroleum exploration. In addition, the study found that many of these measures provide more economic value in benefits than their cost.

The study doesn’t go into how much more GHG reduction and economic benefit could result from use of captured and cleaned methane to displace the use of dirtier fuels such as coal and diesel. That’s an obvious next step, and one that FirmGreen has been pursuing since 2002, with its strategy of displacing dirtier transportation fuels with cleaned methane (known as biomethane) from wasted resources such as landfills, waste water treatment plants, and livestock operations.

“Reliance on oil is the greatest immediate threat to U.S. economic and national security, and also contributes to the long-term threat of climate change,’’ the report states. (page IX of the Executive Summary) Fine so far: we agree!

In the transportation sector, the DOE intends to focus on technologies that “significantly reduce oil consumption and diversify fuel sources for on-road transportation.” Step one (see the chart above) involves continued increases in Corporate Average Fuel Economy (CAFE) standards. Beyond improving fuel efficiency, the DOE seems to have concluded that electrification of fleets represents the next best step. What?

Considering that almost 20% of our electricity generation is still powered by coal, electrification of vehicles will do little to reduce carbon emissions. So a push toward EV’s prior to cleaning up our electrical generation seems odd. However, recent government efforts to support primarily one biofuel – ethanol – have come under heavy criticism and may partially explain the lack of enthusiasm for biofuels. It’s no secret that ethanol production from corn puts it in competition with food supplies, and may require more energy to produce than can be obtained from using the fuel. Current research in this area is focusing on use of waste crop products, such as corn stalks and husks, but researchers admit that such fuels are multiple generations away from market viability. Hydrogen and fuel cells aren’t anywhere near ready for prime time either. Hence, the DOE concludes a shift to EV’s is the best near-term opportunity to reduce reliance on petroleum for transportation.

The report mentions another hurdle for biofuels besides ethanol: alternative transportation technologies must compete with the established fueling infrastructure. That hurdle is real, but it is unlikely to be overcome if there is little will to do so. We think another fact stated in this same report (p.17) provides ample reason for a will to surmount this hurdle: oil imports at current prices contribute 70% of the United States’ trade deficit. Budgets are tight these days, but some funding of new fueling infrastructure would also create some jobs, ultimately increasing tax revenues.

The DOE mentions natural gas as a transportation fuel, and then seems to dismiss it as a solution: the report states that “recent expansion of domestic gas reserves has…raised the possibility of exports.” In other words, not only do we have enough for domestic use, but we could actually export to other nations. Strangely, the report then concludes that such a linkage to global markets could make the US economy vulnerable to price swings in that market. This is amazing: it’s a little like concluding that Saudi Arabia’s economy is vulnerable to swings in the global price of oil. Technically true of course, but historically economic vulnerability from oil price swings has been much greater for nations that import than for those that are net exporters.

Some disclosure is appropriate here: FirmGreen is in the business of recovering and cleaning wasted methane (natural gas) from sources such as landfills and waste water treatment plants to produce natural gas fuel equivalent to pipeline quality. Obviously, policies that support adoption of natural gas as a transportation fuel could benefit our company. However, we fail to see how transitioning from a fuel for which we must import almost 50% of what we use, to a fuel that we have in sufficient enough quantity to export makes the US more economically vulnerable.

In fairness to the report, another stated goal is to derive 80% of America’s electricity from clean-energy sources by 2035. A great idea, and one that will require continued innovation, especially in the area of energy storage (i.e., battery technology) and improving the grid to reliably deal with fluctuations in production inherent in renewables such as solar and wind. Domestic natural gas, including biomethane would have a supporting role to play here as well – that of clean backup power when the sun isn’t shining or the wind isn’t blowing. However, greater adoption of renewables for power generation could still be expected to free up domestic natural gas supplies for transportation use. That this is the essence of the Pickens Plan doesn’t mean it’s a bad idea. Until we shift to cleaner power generation, a shift to EV’s will do little to clear the air, though it may slightly reduce demand for imported petroleum.

In our view, improving fuel efficiency is good policy. But we believe a rapid shift toward alternatives such as domestically produced natural gas for transportation is more likely to deliver near-term as well as long-term benefits, both environmentally and economically, over a strategy of electrifying our fleets.
