Obama Administration launches series of actions to accelerate EV adoption; inc. $4.5B in loan guarantees, pursuing 350 kW fast charge

The Obama Administration has announced a series of actions from the Federal government, private sector, and states, as well as a new framework for collaboration for vehicle manufacturers, electric utilities, electric vehicle charging companies, and states, all geared towards accelerating the deployment of electric vehicle charging infrastructure and putting more electric vehicles on the road.

The collaboration, forged by the White House in partnership with DOE and the Department of Transportation (DOT), the US Air Force and US Army, and the Environmental Protection Agency, is centered on a set of Guiding Principles to Promote Electric Vehicles and Charging Infrastructure. 46 organizations have signed on to the principles so far.

Among the actions announced are:

  • Unlocking up to $4.5 billion in loan guarantees and inviting applications to support the commercial-scale deployment of innovative electric vehicle charging facilities;

  • Launching the FAST Act process to identify zero emission and alternative fuel corridors, including for electric vehicle charging across the country, and standing up an effort to develop a 2020 vision for a national network of electric vehicle fast charging stations that will help determine where along the corridors it makes the most sense to locate the fast charging infrastructure;

  • Announcing a call for state, county, and municipal governments to partner with the Federal government to procure electric vehicle fleets at a discounted value;

  • Leveraging the power of data and hosting an Electric Vehicle Hackathon to discover insights and develop new solutions for electric vehicle charging;

  • Publishing a guide to Federal funding, financing, and technical assistance for electric vehicles and charging stations; and

  • 35 new businesses, non-profits, universities, and utilities signing on to DOE’s Workplace Charging Challenge and committing to provide electric vehicle charging access for their workforce.

During past eight years the number of plug-in electric vehicle models has increased from one to more than 20, battery costs have decreased 70%, and the number of electric vehicle charging stations has increased from less than 500 in 2008 to more than 16,000 today—a 40-fold increase.

Electric vehicle coalition. In collaboration with the Administration, 46 industry members signed on to the following Guiding Principles to Promote Electric Vehicles and Charging Infrastructure. This commitment signifies the beginning of a collaboration between the government and industry to increase the deployment of electric vehicle charging infrastructure.

The text of the Guiding Principles:

Building on existing partnerships among federal government, states and communities, electric vehicle and charging infrastructure manufacturers and retailers, electric utilities, national laboratories, universities, and nongovernmental organizations, we endorse the following guiding principles to enhance electric vehicle use and create a national, household, workplace, and urban charging infrastructure that is available to all Americans:

  • Drive the market transformation to electric vehicles by making it easy for consumers to charge their vehicles with grid-connected infrastructure that is accessible, affordable, available and reliable, and interconnected with other low-carbon transportation options where feasible.

  • Promote electric vehicle adoption by increasing access to charging infrastructure and supporting the development of plug-in electric vehicles that are as accessible, available, and convenient as gasoline-powered vehicles.

  • Promote a robust market for vehicle manufacturers, utilities, equipment service providers, and support industries that ensures a consistent user experience, customer choice, and allows for a streamlined permitting process.

  • Enhance American manufacturing competitiveness, innovation, and the development of advanced technology.

  • Attract and leverage private, State, and Federal investment in electric vehicle deployment, infrastructure, research and development, and education and outreach.

  • Enable smart charging and vehicle grid integration through solutions such as demand response, and other energy storage and load management strategies.

The Administration also announced a series of executive actions and directions to increase the charging infrastructure in the US.

Charging infrastructure financing:

  • Unlocking Up $4.5 billion in Loan Guarantees and Inviting Applications to Support Innovative Electric Vehicle Charging Facilities: The DOE’s Loan Program Office (LPO) issued a supplement to its Title XVII Renewable Energy and Efficient Energy (REEE) Projects Solicitation, clarifying that certain electric vehicle (EV) charging facilities—including associated hardware and software—is now an eligible technology under the solicitation.

    The solicitation can provide up to $4.5 billion in loan guarantees to support innovative renewable energy and energy efficiency projects in the United States. Loan guarantees can be an important tool to commercialize innovative technologies because these projects may be unable to obtain full commercial financing due to the perceived risks associated with technology that has never been deployed at commercial scale in the United States.

  • Publishing a Guide to Federal Funding, Financing and Technical Assistance for EVs and Charging Stations: DOE and DOT are publishing a guide to outline specific examples of funding programs, financing incentives, and technical assistance to help advance the nation’s economic, environmental, and energy security, through the support of EVs and charging stations that reduce petroleum use and greenhouse gas emissions from the transportation sector. It will also list current tax credits and incentives applicable to EV charging. The DOE’s Alternative Fuels Data Center provides a comprehensive database of federal and state programs that support EVs and infrastructure.

Supporting the development of electric vehicle charging corridors. The DOT is now soliciting nominations from State and local officials to assist in making designations for alternative fuel corridors. Section 1413 of the FAST Act requires that the Secretary of Transportation designates national EV charging, hydrogen, propane, and natural gas fueling corridors, and the nomination process will ensure that the corridors proposed for designation will create a national network of alternative fuel facilities.

In designating corridors, the DOT will (1) consider the nominated facilities, (2) incorporate existing corridors designated by States, and (3) consider the demand for, and location of, existing fueling stations and infrastructure. DOT will also evaluate applications based on their ability to reduce emissions and collaborate across the public and private sector. Details on this program can be found here or here.

DOE and DOT have also agreed to partner on the development of a 2020 vision for a national network of fast charging stations for EVs in order to facilitate coast to coast, nationwide zero emissions travel.

Building upon DOT’s planned designation of alternative fuel corridors under the FAST Act, DOE and DOT, in cooperation with the DOE National Laboratories, DOT Volpe Center, and other government and industry stakeholders, will commence efforts in fiscal year 2017 to develop criteria that will help identify specific locations for siting fast charging infrastructure adjacent to the DOT-designated national and community corridors.

The proposed effort will address four key areas important to evaluating the potential for a national network for fast charging including:

  1. siting criteria for charging locations;
  2. charging and utility infrastructure needs and cost assessment;
  3. impacts of electric demand charges to consumers and utilities; and
  4. potential longer-term innovations including evolution up to 350 kilowatt (kW) fast charging.

The partnership will address these questions to provide the necessary information for the basis of a dialogue with stakeholders to help define public-private partnerships, funding, and financing models for implementing a national fast charging network. Along those lines, the DOE and DOT will be convening stakeholders this fall to identify critical needs for a national network of fast charging stations.

Expanding the EV fleet. The Office of Federal Sustainability is inviting State, county and municipal government fleets to join forces with Federal agencies to maximize their collective buying power, and aggregate their EV and charging infrastructure purchases. In doing so, governments at all levels can lower their procurement costs, expand technology availability, and increase automotive manufacturers’ demand certainty.

The Office of Federal Sustainability will partner with government and agency fleet purchasers to coordinate and aggregate the purchasing of EV fleets, with distinct acquisition procurement strategies to be determined. Alone, the federal government plans to purchase more than 500 plug-in hybrid electric vehicles (PHEV) or EVs in fiscal year 2017.

Municipal fleet electrification. DOE’s Office of Energy Efficiency and Renewable Energy (EERE) will be signing a Memorandum of Understanding (MOU) with the American Public Power Association (APPA) to collaborate on municipal fleet electrification.Through this agreement, EERE and APPA will ensure collaborative efforts to enable electrification of personal and fleet transportation in municipalities throughout the United States. EERE and APPA will provide information to increase education and awareness of the benefit of EVs to public power utilities and local officials, and develop a community action plan focused on smaller communities with fewer than 200,000 electric customers. The partnership will also work to enhance workplace charging efforts at public power utilities, study the impacts of EVs in public power communities, and share insights regarding infrastructure installation and EV interaction with the modern grid.

Technology innovation. The White House Office of Science and Technology Policy (OSTP) will host an EV hackathon this fall. Hackathons are events that bring together coders, data scientists, topic experts, and interested members of the public to discover insights and develop new solutions. The event will take place in concord with the release of anonymized data on EV charging stations to the research and software development community. The ‘EV Hackathon’ represents a unique opportunity to bring together the EV and software communities to collaborate to enhance EV deployment.

On another front, DOE will partner with industry, the National Laboratories, and other stakeholders to develop a study that will examine the vehicle, battery, infrastructure, and economic implications of direct current (DC) fast charging of up to 350 kW, which is expected to be completed by the end of 2016.

A 350 kW charging system could charge a 200-mile range battery in less than 10 minutes. The implementation of DC fast charging has the potential to impact many technology areas and tackle key technological barriers associated with high rate charging (50 kW and above), and fast charging increases the utility of EVs, aides in their adoption, and helps enable widespread use of EVs.

A multi-partner team, led by PNNL as part of the Battery500 research consortium, will receive an award of up to $10 million per year for five years to drive progress on DOE’s goal of reducing the cost of vehicle battery technologies.

Battery costs exceeded $500/kWh when President Obama launched his EV Everywhere Grand Challenge goal of making EVs that are as affordable and convenient for the American family as gasoline-powered vehicles, and low-cost, high performance batteries are a key component of the strategy to attain the President’s goal.

The Battery500 Consortium aims to triple the specific energy (to 500 Wh/kg) relative to today’s battery technology while achieving 1,000 electric vehicles cycles. This will result in a significantly smaller, lighter weight, less expensive battery pack (below $100/kWh) and more affordable EVs. The Battery500 consortium will include four DOE National Laboratories and five universities in an effort aimed at achieving revolutionary advances in battery performance. Consortium partners include the following:

  • Pacific Northwest National Laboratory (research partner and advisory board)
  • Brookhaven National Laboratory
  • Idaho National Laboratory
  • SLAC National Accelerator Laboratory
  • Binghamton University (State University of New York)
  • Stanford University (research partner and advisory board)
  • University of California, San Diego
  • University of Texas at Austin
  • University of Washington
  • IBM (advisory board)
  • Tesla Motors, Inc. (advisory board)

Increasing charging infrastructure in homes and workplaces. The Standard for High Performance Green Buildings will consider a revision to encourage EV-ready building practices. By employing EV-Ready building practices, multi-unit dwelling and commercial building developers can prepare a facility with electrical infrastructure to accommodate a future charging station installation, resulting in significant cost savings for building owners and tenants.

To encourage more EV-Ready development in cities and states across the country, an EV-Ready building code measure has been introduced to the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) 189.1, a standard for high performance green buildings that in 2018 will become the basis for the International Green Construction Code. Through the adoption of this EV-Ready building practice, cities and states can align with the EV building strategies identified by Federal agencies in the 2016 Guiding Principles for Sustainable Federal Buildings.

Expanding DOE’s Workplace Charging Challenge. DOE’s Workplace Charging Challenge encourages America’s employers to commit to providing EV charging access for their workforce. Participating employers include organizations that are assessing their employees’ need for charging to those who have successfully launched workplace charging programs. DOE’s Workplace Charging Challenge has grown to more than 350 partners since its launch in January 2013, and is on track to meet its goal to partner with 500 United States employers by 2018. The 35 new partners include:

Finally we see the first steps towards truly accelerating the adoption of EVs. Everything is coming together and we will be looking at a VERY different landscape by 2020.

- Over 2 million EVs on American roads
- Over 10,000 charging stations and 100,000 charge points.
- Virtually all major manufacturers offering multiple 200-300mile EVs
- Under $25K EVs available for mass adoption.

- Coal usage on the grid will be below 30% of electricity generation
- Wind, solar, hydro and nuclear will be approaching 50% of the grid.
- There will be no new diesel LDV vehicles from any manufacturers.

We're reaching an inflection point.

Bobcom52

The aim to reach a charging rate of 350kW is admirable.
I guess it will be interesting to see what policies get up after the next election.

Global warming will be stopped by technological progress like self-driving BEVs and affordable solar power. Politics will not be important in that regard. On that issue it will not matter whether Hillary or Trump takes office. There are too many interests for anything material to happen. Nevertheless, IMO Trump may protect the free world from the global rise of fascist Islam whereas Hillary obviously cannot.

When self-driving vehicles are a reality in 2 to 3 years from today BEVs will become the most affordable way to transport people and goods because BEVs unlike gassers and diesels can be build to last a million miles and electricity is by far the cheapest type of fuel. For BEVs to make economic sense they need to do at least 50,000 miles per year and preferable 100,000 miles per year and we need self-driving tech to do that for all vehicles made.

Tesla new Master Plan will allow Tesla owners to add their fully autonomous cars and Tesla Trucks to Tesla’s coming autonomous transportation fleet when the owner is not using his own vehicle. In that way the owner can do the usual 15,000 miles on his car by himself and another 85,000 miles can be done by making it available for Tesla’s transportation services. If the Tesla owner is just paid 10 cents per mile and gets refunded for electricity and extra service for interior maintenance (like new seats for every 200,000 miles) he could make 8,500 USD per year (85,000*0.1=8,500USD).

A good list of progress milestones, DaveD. All at risk in the US if Americans elect climate-change deniers.

Engineer-Poet

I read the words of Henrik and DaveD and wonder if they're nuts.  Fast EV charging demands large amounts of power at the beck and call of the driver.  Who in their right mind thinks that wind or solar can have ANY significant role in this?!  The only carbon-free sources of electric power which are there when called upon are water behind a dam and uranium in a reactor.

Opbrid

350kW isn't that difficult, but it helps to bump up the voltage to 750V or higher to lower the amperage. We're doing 650kW with buses for some time now, and 350kW is becoming quite common in the bus charging industry. Of course we don't use hand held plugs which helps a lot.

HarveyD

Ground e-transportation followed by limited air e-transportation will eventually require more clean low cost electricity. Hydro has not been fully (globally) exploited yet but new plants are further away from users and cost much more than 10 and 20 years ago.

Recent Hydro PPs cost about $0.06/kWh versus $0.22/kWh for NPPs. Both can supply clean 24/7 energy but NPPs cost 3X more and are not (yet) acceptable to the majority.

Longer term (2050+) NPPs may be improved and secured enough for better acceptability but high cost may still be a problem.

Wind and Solar (with enough lower cost storage) may become the most affordable alternative clean electricity sources for the next 35+ years. The majority of PHEV and BEV owners will easily adapt and automatically connect to the grid when energy is available and/or at lowest cost. Availability and lowest cost normally coexist. Rooftop solar panels + home storage units will eventually fill a good percentage of needs in many places. NGPPs will fill in on an as required basis.

There will be no shortage of clean electricity!

@Harvey, occasionally you write so presciently that I wonder where this insight hides the rest of the time.

HarveyD

@e-c-i.com:

For many posters, it is still difficult to admit that most transportation means will be electrified with clean REs by 2035/2040 via flash ultra quick chargers.

Very few posters will admit that bio-fuel FCs may become the solution of choice for PHEVs and larger e-vehicles by 2025/2030 or so,

However, fully ADVs may not become common place much before 2030 or so for 101 reasons.

Engineer-Poet

Harvey thinks

  • the hydropower which suffices for the 8 million of Quebec can be scaled to the 350 million living north of Mexico, and
  • "biofuels" which consume 40% of the US maize crop to make about 10% of its LDV fuel (and an even smaller fraction of the energy therein) will become a "fuel of choice", rather than a gap-filler.

Harvey thinks this because he can't do arithmetic.

HarveyD

E-P.

1) Canada can go from (2014) 61% REs to 90+% REs by 2030/2035 with more hydro + Solar ++ Wind and by NOT exporting low cost REs to USA like Nfl, BC and QB are planning to do.

2) Bio-fuels, for future more efficient FCs, do not have to be produced with edible corn/maize. Forestry, agriculture, domestic and industrial wastes and many other non-edible feed stocks could be used.

NB: USA farmers and fuel firms used corn because surpluses had forced corn prices very (too) low. A few ethanol plants pushed corn prices up by 2X and 2.5X and large corn producers were happy.

Engineer-Poet

Ah, Harvey AT LAST admits that his solution is limited to Canada; not even the USA, let alone the rest of the world, has the required elements of geography to do the same.

Actually, Harv, the USA used to have a program of keeping large grain reserves and holding cropland out of production to prevent prices from cratering when big crops came in.  That got unpopular when the price went up too much once (sound familiar?) after which overproduction was the rule.  Ethanol was the new sink for the surplus... and never mind what all the extra nitrate pollution, soil erosion and loss of wildlife habitat did to everything else.

Now the USA turns enough maize into motor fuel to affect world prices.  Meat producers were trying to get the ethanol mandate reduced or dropped when grain prices spiked again a few years ago, and the food riots which started the Arab Spring (which is now the Islamist Winter) were directly traceable to those same high grain prices.

HarveyD

Tks E-P for confirming that bio-fuels should not be produced with edible feed stocks such as corn/maize, grains, sugar beets, sugar canes etc.

Since growing (young) forest sink a lot more CO2 than older forest, faster growing trees could be harvested more often and used to produce relatively clean biofuels for future Nissan biofuel FCs. It may reduce forest fires as a fringe benefit? With warmer climate, older forests will burn more often and temporary increase GHGs?

HarveyD

To produce relatively clean biofuels with feed stocks from non food producing lands, the following fast growing trees could be used:

Very fast growing (Royal Empress) trees could be planted and harvested every 3 to 5 years in Southern USA (zones 7 to 11) and/

Very fast growing (Lombardy and Hybrid Poplars) trees could be planted and harvested every 4 to 6 years in mid and Northern USA and Southern Canada.

In some cases, existing trees may have to be harvested to make room for faster growing varieties.
