Four Bright Green Spots in the Budget
As I’ve mentioned before, I’ve been spending a lot of time this year helping clients see how the American Reinvestment and Recovery Act (ARRA) can help support their environmental initiatives.
But last week, when the President sent Congress the fine print of his proposed Fiscal Year 2010 budget, even I had a start: Never before has US government set out to make its spending so green. Not even the stimulus.
Here’s a list of Four Green Bright Spots:
1. Pouring Money Into Water. The Environmental Protection Agency’s funding will increase roughly 30 percent from the $7.6 billion in the fiscal 2009 omnibus to $10.5 billion.
There’s a massive increase for water infrastructure, including $2.4 billion for the Clean Water State Revolving Fund, a low-interest wastewater loan program that helps states construct water treatment facilities. (The fund received just $689 million in fiscal 2009.) The Drinking Water State Revolving Fund would receive $1.5 billion, up from $829 million this year.
2. Carbon Infrastructure. The EPA will dedicate $17 million to the development of a GHG registry for US greenhouse gas emissions. As we’ve written before, this is a necessary first step toward regulating carbon emissions.
3. Oil is Out. Over at the Department of Energy, the proposed spending is flat from last year. Of course, that doesn’t include the nearly $40 billion showered on the department from the stimulus law for alternative-energy and efficiency initiatives. There are significant changes in emphasis on spending, though when it comes to fossil fuels. The budget completely cuts funding for the oil research and development program authorized by the 2005 Energy Policy Act. Finally, a budget that leaves behind the perverse incentives supporting fossil fuels that are costing us so much more than their sticker price.
4. Adaptation Gets Attention. State Department is contributing $600 million to two World Bank funds, one that supports clean technology in the developing world and the other that helps spur adaptation solutions in countries struggling with climate change. Over at Interior, the department is touting $183 million in increases for clean energy and the mitigation of climate impacts on the home front.
I’m sure there’s more to find, but the four points give some sense of this extraordinary bright green spending plan that, if adopted, will change the federal government’s impact on the economy.
The United States Through a Carbon Lens
We wrote earlier this week about the prospect of a national GHG registry that could provide an up-close view of the nation’s carbon emitters. While we’re waiting, a team at Purdue has delivered a fascinating tool that provides a taste of that future. The Vulcan Project is a initiative funded by NASA and DOE that is taking emissions data from 2002 and presenting it in extraordinarily accessible ways.
This week, the Vulcan team released an application for Google Earth that allows everyone to view emissions state by state or county by county across the United States. You can even layer over emissions from power plants and transportation. The team has posted a You Tube video demonstrating their work here.
For the first time, you can fly over emitters and get a visual sense of what pollution is coming from where. I believe tools like this will be crucial to spark entrepreneurial solutions to address climate change.
Renewable Portfolio Standards: An Avenue for Fostering Alternative Energy Projects
Government’s response to the focus on climate change must be holistic and visionary. One regulatory avenue for fostering alternative energy projects that assist in the battle against climate change is a Renewable Portfolio Standard (RPS). At its core, an RPS is a requirement that retail electricity suppliers purchase a certain percentage or quantity of renewably generated energy. Currently 25 states and Washington DC have mandatory targets for retail electricity purchases and 4 states have non-binding goals. In 2007 the House of Representatives passed an RPS, but the US Senate did not.
While most RPS programs share a common goal of encouraging the production of renewably generated energy, they vary in terms of purchase goals, timeframes for compliance and eligible technologies. Wind, solar, and geo-thermal are eligible under most of the RPS programs, but eligibility criteria varies widely with respect to other technologies and fuel sources such as bio-mass, landfill-gas, municipal solid waste, hydropower, and fuel cells. While the advantages in terms of climate change impacts associated with renewably generated energy may seem obvious (no emissions), less obvious may be the results stemming from the expansion of several states’ RPS programs into non-renewable areas.
The variety of RPS programs has allowed for many designs and policies to be demonstrated. Although not technically renewable, combined heat and power, energy efficiency and demand side energy efficiency have found their way into several of the RPS programs. By reducing demand for electricity, air emissions from current fossil fuel fired power plants is reduced to the extent that power is not needed. Arguably, the impact from reducing the demand of one megawatt of power, should have the same air emissions impact as the creation of one megawatt of renewably generated power and as such the nexus to demand management and energy efficiency in an RPS becomes self evident. Energy efficiency, demand management, and renewable energy should co-exist in an RPS and are a fundamental part of the future of our energy delivery system. As states continue to adopt and refine RPS programs, policy makers should bear in mind what this future of a sustainable energy delivery system may look like.
The US Department of Energy (DOE) has promoted (in part) a vision of the future that includes a hydrogen based energy delivery system that begins with small-scale distributed generation (DG) systems fueled by hydrogen. These DG systems provide stationary power and may also dispense hydrogen for hydrogen-fueled vehicles. DOE has funded several projects that evaluate the potential for the generation of wind-to-hydrogen, solar-to-hydrogen, geothermal-to-hydrogen and hydro-to-hydrogen, hydrogen generation systems. The common denominator is that renewably generated electricity is used to power an electrolyzer to generate hydrogen. Renewably generated hydrogen is the future. To bridge the gap to the future, however, Renewable Portfolio Standards should be developed that include hydrogen generated from fossil fuels.
One notable Wind-to-Hydrogen (also Solar-to-Hydrogen) demonstration funded by DOE is in Hawaii at the Kahua Ranch test site. There, the wind turbine has been configured to produce 48VDC, the solar array has been redesigned to produce 48VDC and each of these generation sources is connected to 24 battery cells allowing 48VDC short term electricity storage. The electricity is used to power an electrolyzer that generates hydrogen which is then stored in a low pressure hydrogen storage tank. When electricity is needed the hydrogen is used to run a 48VDC Plug Power Gencore Fuel Cell system.
Fuel cells utilize hydrogen and hydrogen-rich fuels to generate electricity and useful heat in a remarkably efficient way. A fuel cell is an electrochemical device that combines hydrogen and oxygen to create electricity heat and water. Because the conversion of hydrogen occurs without combustion, fuel cells do not produce the emissions normally associated with combustion such as carbon dioxide, oxides of nitrogen, carbon monoxide and particulates. Fuel cells are secure, reliable and high-quality power at the point of demand, with some systems able to provide high quality thermal energy as well as electric energy. Because many renewables like wind and solar produce intermittent power, a natural symbiotic relationship exists since fuel cells have the ability to generate electricity regardless of weather conditions. Fuel cells can act as a power storage technology converting off-peak generated wind and solar energy to peak power. Clean power that emits virtually no pollution during the power generation is a natural complement to intermittent renewable technologies such as wind and solar.
Introducing fuel-neutrality for fuel cells into every RPS in the short term will provide a bridge to renewably generated hydrogen. Currently, supplies of renewably generated hydrogen are scarce and the delivery systems not readily available. Simply put, today’s fuel cells that use existing fossil fuels (much more efficiently and cleaner than any combustion engines) can also use hydrogen from renewable sources as they become cost-competitive and the production and delivery of renewably generated hydrogen catches up with the demand. In this manner, the use of hydrogen from the conversion of hydrocarbons is seen as a temporary expedient to the long-term development of fuel cells. Moreover, even when they run off of fossil fuel derived hydrogen, the inherent efficiencies of the fuel cell systems, and the lack of combustion is an incremental advancement in the fight against climate change.
The vision of the future displayed in the Kahua Ranch project will only be advanced in the short term if fuel cells that utilize hydrogen reformed from fossil fuels are made a part of any federal RPS. At its core, a RPS should promote technologies that have a legitimate chance of substantially lowering pollution, reducing stress on the utility grid, spurring economic development, increasing our energy independence and fostering demand for hydrogen production and delivery systems that will eventually be renewably generated.
Initially, it may sound counter intuitive, but by allowing hydrogen generated from fossil fuels in any RPS, a critical component to generating the demand for renewably generated hydrogen will be in place and our path toward a more sustainable and energy independent future will be advanced. This model is not without precedent. New York, Pennsylvania, Connecticut, Minnesota, Colorado, Maine all include fuel cells as renewable resources regardless of the fuel supplied.
