Research says policies and subisides for plug-ins wrong

A new paper from research professors at Carnegie Mellon University, Arizona State University, and an engineer at the RAND Corporation says that subsidies and policies targeting plug-ins with small battery packs would produce more benefits at lower cost. Contrary to current policies and subsidization schemes.

The paper by Associate Professor Jeremy J. Michalek of Carnegie Mellon University, Assistant Professor Mikhail Chester of Arizona State University and Constantine Samaras of the RAND Corporation will publish in the summer issue of the journal Issues in Science and Technology and is based on an earlier study by the authors regarding electric vehicle adoption strategies.

The researchers contend that promoting the adoption of higher-cost, lower production vehicles like plug-in electrics (PHEV) and battery electrics (BEV) with large battery packs provides little benefit in a dollar-for-dollar comparison. Vehicles with smaller battery packs, such as non-plug-in hybrids, and short-range plug-ins, offer more benefits per dollar spent.

This study is based on a false premise. The objective of the current incentives is to spur the development of new battery technologies. To do so they need to create a market that justifies the private sector R&D spending that is needed to create new battery technologies that won't have to be subsidized. The idea that the end goal of the program is to lower the emissions on the tiny number of current technology cars that incentives apply to is just ludicrous. The final paragraph is just astounding, "They note that future changes in battery chemistry and composition may have larger benefits at lower cost, but these changes could take decades to realize and public policy is generally near-term in scope." Politicians finally look farther forward than the next election and their reward is being undermined by misguided studies like this. Very sad.
From the Energy Improvement and Extension Act of 2008, arguments in the Congressional Record (110th Congress, pages ~2,000 onward), I see nothing from anyone supporting this bill about how this would create a "long term" approach to "adoption" or promote future battery technologies. In fact, if you read what was written in this article and the papers these professors wrote, you'll see that even your belief that this would promote long-term battery production by giving incentives to make money selling EVs is flawed. No one making EVs is profiting by much, Lindsay. Many of them, if you read my article on "Compliance Cars" are building electrics purely because California is forcing them to - and those electrics will be in extremely limited, unprofitable numbers. So I'll have to say that everything you've stated in an attempt to refute these studies and my writeup on them is based on nothing but imaginary goals you yourself wish these plug-in incentives promoted. In reality, the PHEV tax credit is nothing more than a public relations scheme, as is 90% of what comes out of Washington, frankly.
