clean energy technology
Though it is unlikely that the first generation of plug-in electric vehicles (PEVs) will be adopted by the masses, there is a compelling case for everyday consumers to take a look at these vehicles when they become available this winter. There is no silver bullet to solving climate change, but PEVs could play an important role as one of a broader set of solutions. As is the case for many climate solutions, the benefits from PEVs are more than environmental. In this three part series, I’ll make the case for PEVs based on the gamut of issues that matter to Americans – national security, the environment, and their wallets.
The first two weeks of August saw two big news items from the U.S. Department of Energy (DOE) related to carbon capture and storage (or CCS, for an overview of CCS see the our Climate TechBook CCS brief). First, on August 5, DOE announced its plans for FutureGen 2.0. One week later, President Obama’s Interagency Task Force on CCS delivered its final report and recommendations regarding overcoming “the barriers to the widespread, cost-effective deployment of CCS within 10 years, with a goal of bringing five to ten commercial demonstration projects online by 2016” (see the separate post regarding the task force’s report).
Why is this FutureGen announcement from DOE important? CCS is anticipated to be a key technology for achieving large reductions in U.S. and global greenhouse gas (GHG) emissions (for example, see the recent projection from the International Energy Agency that CCS could provide nearly one fifth of all global GHG emission reductions by mid-century). Initial commercial-scale CCS demonstration projects are a critical step in advancing CCS technology; these projects provide valuable experience and confidence in “scaling-up” CCS technologies and technology improvements and cost reductions from “learning by doing.” The aforementioned report from the Interagency Task Force on CCS notes that FutureGen is one of ten planned CCS demonstration projects supported by DOE (see Table V-2 of the task force’s report for the list of seven power-sector and three industrial CCS projects).
The FutureGen project has had a somewhat tumultuous history. In 2003, DOE announced its plan to work with an industry consortium on the FutureGen plant to demonstrate commercial-scale integrated gasification combined cycle (IGCC) technology coupled with (pre-combustion) CCS at a single new coal-fueled power plant (with DOE covering most of the project’s costs). In 2007, the industrial consortium selected a site in Mattoon, IL, for the FutureGen power plant. In 2008, though, DOE abandoned the idea citing the escalating cost estimates for the FutureGen project and decided instead to pursue cost-sharing agreements with project developers to support multiple CCS demonstration projects (this time with DOE covering a smaller fraction of project costs). DOE received only a small number of applications for this restructured FutureGen approach, and this change of plans came in for some criticism from the Government Accountability Office (the GAO report also provides a helpful overview and history of what might now be referred to as “FutureGen 1.0”).
In 2009, the Obama Administration revived plans for a single FutureGen plant and restarted work with the industrial consortium on preliminary design and other activities, promising a decision in 2010 on whether to move forward with the project. That decision came on August 5 and included another shift in DOE’s plans for the FutureGen project (now dubbed “FutureGen 2.0”). Energy Secretary Chu announced the awarding of $1 billion in Recovery Act funding for the repowering of an existing power plant in Meredosia, IL, as a coal-fueled power plant using oxy-combustion and CCS. With “FutureGen 2.0,” DOE decided to change from building a new plant to repowering an existing one and chose a different technology (oxy-combustion with CCS rather than IGCC with CCS).
When subsidizing initial CCS demonstration projects, policymakers should support a variety of relevant technologies and configurations. With respect to applying CCS technology to coal-fueled electricity generation, there are factors that are expected to make certain variants of CCS technology more appropriate for certain circumstances. These factors include the application of CCS with: new plants vs. retrofitting/repowering existing plants; different coal types; and various geologic formations for CO2 storage. Importantly, there are three types of CO2 capture technology—pre-combustion, post-combustion, and oxy-combustion—with the latter two appropriate for use at existing coal-fueled power plants (see our Climate TechBook CCS brief for details).
With its new approach for “FutureGen 2.0” DOE has focused on large-scale demonstration of oxy-combustion. Of the ten CCS demonstration projects supported by DOE, FutureGen will be the only one to use the oxy-combustion technology. Of the 34 large-scale power plant CCS projects worldwide tracked by MIT, only four (counting FutureGen) use or plan to use oxy-combustion, and FutureGen will be the only such oxy-combustion project in the United States. Given the greater focus so far given to the two other alternative CCS approaches, oxy-combustion is likely the CCS technology that can most benefit from the FutureGen large-scale demonstration project.
With its new approach for “FutureGen 2.0,” DOE is taking an important step in demonstrating a portfolio of different CCS technologies. Such demonstrations, along with other supportive government RD&D policies, provide a critical “push” for low-carbon technologies. Long-term policy certainty (such as from a GHG cap-and-trade program) for the private sector regarding future GHG emission reduction requirements can provide the necessary technology “pull” to guide private investments in widespread deployment of CCS and other low-carbon technologies.

Last week, the Obama Administration’s Interagency Task Force on Carbon Capture and Storage (CCS) released its final report and recommendations. President Obama created the task force, co-chaired by the Department of Energy (DOE) and the Environmental Protection Agency (EPA) and involving 14 executive departments and federal agencies, in February. The President’s directive charged the task force with delivering “a proposed plan to overcome the barriers to the widespread, cost-effective deployment of CCS within 10 years, with a goal of bringing 5 to 10 commercial demonstration projects online by 2016.”

By all indications, the climate bill is done for the year. A casualty of … well, you’ve been hearing the blamefest.
So what’s next?
Unfortunately, none of the problems we sought to fix with the climate bill have been solved by ignoring them.
Power companies and businesses still need to know what carbon emission requirements lie ahead of them before investing millions of dollars in new equipment – especially for carbon capture and sequestration, nuclear power, renewable energy, energy efficiency, and other low-carbon alternatives.
The Midwest Governors Association (MGA) recently held a briefing in Washington for congressional and federal agency staff to highlight key regional developments in clean energy job creation. As the Senate prepares to take up energy legislation this summer, state government officials and representatives from business groups and environmental organizations in the Midwest described the progress they have made promoting renewable energy in order to create jobs, benefit the environment, and increase energy security.
This post was written with Cynthia J. Burbank, National Planning and Environment Practice Leader at Parsons Brinckerhoff. It first appeared in the National Journal Transportation Experts Blog in response to the question: What should transportation departments do for electric cars?
The call for the government to act to promote plug-in electric vehicles (PEVs), and all clean alternative fuels for that matter, is to correct the clear market failures that exist in today’s petroleum-based transportation sector.
Historically, petroleum has been a key driver in the growth of the economy and development of nations worldwide. Gasoline and diesel fuel’s impressive energy density, portability, and low production cost made it the fuel of choice for nearly a century. All the while there have been costs, although they haven’t always been obvious. Petroleum’s impact on climate change and U.S. energy security, and the risks of drilling, result in real and significant costs to society, and currently the price of petroleum does not include those externalities.
It will probably take some time to fully understand what went wrong in the Deepwater Horizon oil spill, and what ought to be done to make sure it doesn’t happen again. But at least one thing is already perfectly clear: recent technological advances in extracting oil in deep water offshore have been dramatic, whereas unfortunately the same cannot be said for technological advances in spill prevention and cleanup techniques.
Why is this the case? Innovation is complicated, but we do know something about it. In the private sector, the profit motive is a primary driver of innovation. Because of the world’s seemingly insatiable demand for petroleum products (mainly gasoline and diesel), oil companies have invested hundreds of millions of dollars in offshore drilling technology (just one company, GE Oil & Gas, reported offshore oil and gas drilling-related R&D spending of $150 million from 2009-2011) in order to reap tens of billions in proceeds from fuel sales (for fiscal year 2009, MMS reported oil production worth $20.2 billion from the Gulf of Mexico federal outer continental shelf). According to the U.S. Energy Information Administration (EIA), oil production from federal offshore areas accounted for 29 percent of total domestic oil production in 2009. In 2009, ultra-deepwater offshore drilling (drilling in more than 5,000 feet of water) accounted for about a third of total federal offshore oil production, and ultra-deepwater production tripled from 2005 to 2009. Until recently there has been no comparable incentive for spill prevention and cleanup techniques: the pre-Deepwater Horizon spill record had been excellent, lulling both regulators and oil companies into complacency.
The free market by itself cannot motivate investment in spill prevention and cleanup technology, because spills themselves yield public damage, not private profits. Our government, on behalf of the public interest, could have put rules in place that would have motivated the private sector to make such investments – such as requiring oil companies to actually demonstrate that spill prevention technology works as a condition for obtaining drilling rights.
We have an analogous situation with respect to energy security and climate change. The free market by itself is driving innovation, but in the wrong things: in energy investments that are warming the climate and making us ever more dependent on foreign oil. We need our government to intervene on behalf of the public interest to motivate private investment and innovation in clean energy, through comprehensive energy and climate legislation.
The catastrophe in the Gulf is still unfolding, and will ultimately provide many lessons relevant to our energy and environmental future. But one lesson we can take to heart and act on right away is that there is a profound public interest in spurring innovation in clean and safe energy and that the private market on its own will not adequately provide it. It is our job as the public to demand it, and it is our government’s job to use all the tools at its disposal – from regulations to incentives to penalties – to make it happen.

Previous posts in this series discussed how the demand for electricity from plug-in electric vehicles (PEVs) would affect the grid as well as a potential problem related to clustering. This final post describes an opportunity for these vehicles to help increase the stability of the grid and hold down utility rates for consumers. As a reminder, a PEV is either an all-electric vehicle (EV) or a plug-in hybrid electric vehicle (PHEV).
In our previous post in this series, we provided evidence that the existing electrical grid has enough spare capacity to accommodate plenty of plug-in electric vehicles (PEVs), if the right incentives are put in place. In this post, we will discuss a technical problem that has its roots in social behavior.
The transition from traditional powered vehicles to electric vehicles will not be without its hiccups. While the aggregate impact of PEVs on the grid is likely moderate, one concern is clustering, which can be thought of as the realization of the famous comic strip Keeping up with the Joneses. If people buy what their neighbors have, this could lead to a clustering of PEVs in certain neighborhoods which might place excessive demand on local areas of the grid.
One of the main concerns over the electrification of vehicles is their impact on the electrical grid. Will they lead to power outages due to the increased demand in certain areas? Will a marked increase in electricity demand raise prices for consumers who don’t own a plug-in hybrid electric vehicle (PHEV) or an all-electric vehicle (EV)? In a series of blog posts, we’ll take a look at a claim from some utilities that vehicle electrification could actually help improve the stability of the grid while keeping costs low through a process called frequency regulation.
In this post, we’ll try to answer the capacity question. In order to determine whether the grid has the capacity to handle the influx of Plug-in Electric Vehicles (PEVs or PHEVs/EVs), utilities must estimate at what time of day these vehicles will demand power from the grid and how many of them the grid can charge at a time without causing power disruptions.
