  • The Batteries for Advanced Transportation Technologies (BATT) Program is supported by the U.S. Department of Energy Office of Vehicles Technologies (FCVT) to help develop high-performance rechargeable batteries for use in electric vehicles (EVs) and hybrid-electric vehicles (HEVs). The work is carried out by the Lawrence Berkeley National Laboratory (LBNL) and several other organizations, and is organized into six separate research tasks.

  • The Chilean Agency for Energy Efficiency is developing an energy efficiency labeling system for new vehicles due out in 2011 and will be mandatory starting in September.  (Diario Financiero, 12/16/10)
  • Scientists at the University of Costa Rica are developing solar cells sensitized with dyes from local plants.  Benefits of the cells include its cheaper production price, flexibility and thinness, and ability to produce power with very little light.  However they are not yet as efficient as the present day silicon solar cells. (El Financiero CR, 12/14/10) Mitsubishi Motors will release the first electric car in Costa Rica, called iMiEV.  The car is 100% electric, automatic, is powered by a lithium-ion battery, has room for five people and will cost $61,500.  According to the company, Costa Rica was chosen for car’s release in the Americas due to its environmental record and goal to become carbon neutral by 2021.

    The Fraunhofer Institute is using a redox flow battery, a type of cell that uses two electrolytic fluids exchanging protons through a membrane. This process generates electricity. Although this type of battery isn't new, the Fraunhofer Institute improved the energy density, making it equivalent to that of a lithium ion battery.

  • The paper discusses the use of a dual energy storage system based on batteries and supercapacitors in hybrid electric vehicles (HEV). The battery has a large energy density, enabling an all-electric driving range of 100 km, while the supercapacitor has a large power density and provides peak power during acceleration and regenerative breaking. The paper discusses the benefits and drawbacks of both storage systems and the specific requirements imposed by the hybrid drive train. Coupling such a HEV to the grid allows interaction between grid and HEV, providing the grid with a controllable load. Depending on the communication between the hybrid fleet and the grid, this load can be controlled by adjusting the electricity price in order to allow a higher penetration of intermittent renewable energy sources such as wind parks in the grid and if the communication allows the transmission system operator to reduce the load imposed on the grid by the hybrid fleet, the hybrid fleet can become part of the secondary frequency control reserve. In case of sudden demand or supply fluctuations, the hybrid fleet can assist in primary control of the grid. Due to the dual energy storage system the HEVs can also provide fast load tracking to keep the voltage in microgrids at the desired set point. An experimental setup with a battery, grid coupling and induction machine proves the feasibility of the concept.

The transition to a Zero Emission Vehicles fleet for cars in the EU by 2050 - 1 views

  • Decarbonising transport is central to achieving Europe’s policy commitments on climate change. T ransport is expected to deliver a 60% greenhouse gas (GHG) emissions reduction target of the EU for 2050. Achieving these commitments is expected to require a complete decarbonisation of the passenger car fleet. The more ambitious COP21 commitment to limit temperature rises to 1.5°C will also likely demand a complete decarbonisation of transport by 2050.
  • Attaining a 100% ZEV fleet by 2050 will require all new car sales to be ZEV by 2035 (assuming a similar vehicle life-time as today) and a substantially faster introduction of ZEVs and PHEVs than current policy and likely 2025 policies will achieve .
  • Compared to the CO2 emission reductions targeted in the current EU plan, the transition to a 100% ZEV car fleet by 2050 will result in an additional reduction of the cumulative CO2 emissions in the period 2020 and 2050 of 2.2 to 3.9 gigatonnes. The current EU White Paper for T ransport, targets to reduce the transport emissions by 60% compared to 1990.

  • The best option for a rapid emission reduction is to focus on BEVs rather than PHEVs whereby the EU goes directly and aggressively to 100% ZEV sales. A scenario where PHEVs are first will push the strong ZEV growth further into the future and will ultimately require a larger effort at a later time. However, the impact of (an early fleet of) PHEVs on reducing ZEV costs, increasing consumer acceptance and promoting investments in charging / fuelling infra is difficult to predict / model and may play an important role as well.
  • The “Tank to Wheel” amount of energy needed for transport will be reduced by 78% compared to today for a transition to a BEV passenger car fleet. A transition to a 100% fuel cell electric vehicle fleet will result in a 46% reduction of energy for the EU’s car fleet.
  • Around 1,740 million barrels of oil per year could be saved by 2050 with the transition to a zero-emission passenger car fleet, the equivalent of € 78 billion at the current price of 45 $ per barrel.
  • The GHGs from oil will potentially get higher if shifting to for example oil sands .
  • Purchase cost parity is assumed to be achieved in the period 2022-2026 for a BEV and a comparable internal combustion engine vehicle (ICEV), with BEVs being comparatively lower in cost after that. Parity at Total Cost of Ownership (TCO) level will be achieved 2 to 4 years before the purchase cost parity is achieved. The average TCO for a ZEV will be €0.04 to €0.06 per kilometre less than an ICEV by 2030.
  • This represents societal savings of € 140 billion to € 210 billion per year for a 100% ZEV EU car fleet.
  • A mass market for ZEV cars will create synergy for the cost competitive development of a ZEV LCV (Light Commercial V ehicles) market representing 17% of the light vehicles emissions. It will also accelerate the development of a HDV (Heavy Duty V ehicle) ZEV / PHEV market for passenger and goods transportation. It will also free up advanced biofuels for other transport sectors.
  • A lithium-ion battery manufacturing capacity of 400 to 600 Gigawatt hours will be required at the point where 100% of the passenger cars in Europe sold will be BEV . This is the equivalent of around 10 to 14 “Giga factories” representing a value of €40 to 60 billion per year for cars alone.
  • In addition, as BEVs have superior driving performance characteristics and people used to driving electric do not return to ICEVs, the transition may become demand driven once the price, range and infrastructure barriers have been removed.

  • There’s a promising new entry in the race to build cheap batteries for storing energy from solar panels and wind turbines. Stanford researchers led by Yi Cui, a professor of materials science and engineering, have demonstrated a partially liquid battery made of inexpensive lithium and sulfur. Cui says the battery will be easy to make and will last for thousands of charging cycles. Cui believes that the material and manufacturing costs of the battery might be low enough to meet the Department of Energy’s goal of $100 per kilowatt-hour of storage capacity, which the DOE estimates will make the technology economically attractive to utilities. Existing batteries can cost hundreds of dollars per kilowatt-hour of capacity, although several companies are working to commercialize cheaper ones (see “Ambri’s Better Battery” and “Battery to Take On Diesel and Natural Gas”).

  • Most experts agree that prices for energy storage will fall in coming years, but disagree over how far and how quickly. This is an important debate because a significant drop in battery prices could have wide-ranging effects across industries and society itself. In particular, cheaper batteries could enable the broader adoption of electrified vehicles, potentially disrupting the transportation, power, and petroleum sectors.

  • GM's engineers have been flogging the mules -- known formally as "engineering development vehicles" -- pretty hard for a couple of months now and they've got the lithium-ion batteries and electric drivetrain pretty much sorted. Lutz finally got a chance to take one of the range-extended electric vehicles for a spin and notes on his blog, "While the car is still most definitely a work in progress, the thrill of driving electrically -- that instant, silent torque -- is certainly present and accounted for."
