The transition to a Zero Emission Vehicles fleet for cars in the EU by 2050 - 2 views

  • The transport sector is expected to deliver a 60% reduction in greenhouse gas (GHG) emissions in the EU by 2050. Achieving these commitments is expected to require a complete decarbonisation of the passenger car fleet.

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.

    It took me 4 years to respond, but that should not stop me. Energy touches on many aspects of society. We have for example the energy-water nexus which received a lot of attention over the past years. Food is basically energy, and the food sector is a big energy users. Oxygen, hydrogen, methanol, ... are produced with energy and can be combusted ...

    I wonder whether the 21st century will be about the energy & data. Some of the major new industries emerging are data driven. Warfare becomes cyber-warfare. On the other hand, climate change is the defining challenge for our generation, and it mainly relates to energy.

    After 4 years, this post merits more than a few random thoughts, but let's start here.

Renewable energy in Europe - approximated recent growth and knock-on effects - European... - 3 views

  • This report introduces several methods the European Environment Agency (EEA) has developed for assessing and communicating early RES growth and the important knock-on effects that RES growth has on the energy sector and related areas. The report provides specific information at EU and country level on estimated RES progress in 2013, estimated gross avoided carbon dioxide (CO2) emissions and avoided fossil fuel use due to the additional use of renewable energy since 2005, as well as an assessment of the statistical impacts of growing RES use on primary energy consumption.

Grid-scale energy storage applications in renewable energy integration: A survey - 2 views

  • This paper examines both the potential of and barriers to grid-scale energy storage playing a substantive role in transitioning to an efficient, reliable and cost-effective power system with a high penetration of renewable energy sources. Grid-scale storage is a term that describes a number of different technologies with a wide range of characteristics. This versatility leads to the use of storage to perform a number of grid-services. We first enumerate these services, with an emphasize on those that are best suited to mitigate the effects of uncertainty and variability associated with intermittent, non-dispatchable renewable energy sources. We then provide an overview of the current methods to evaluate grid-integrated storage, summarize key findings, and highlight ongoing challenges to large-scale adoption of grid-scale energy storage. We focus on one particular area that is critical to both the efficient use of energy storage in the power grid and its long-term economic viability: the conflict between the technical benefits of this resource, which can provide both power and energy related grid-services (in some cases simultaneously), and the economic challenges of compensating these services within the current market structures. We then examine recent progress in addressing these issues through regulatory changes and other initiatives designed to mitigate previous market failures. This discussion is followed by some remarks about ongoing regulatory and market design challenges. The paper closes with a summary of the ideas presented and a discussion of critical research needs.

Capital-energy substitution: Evidence from a panel of Irish manufacturing firms - 2 views

  •  
    "We use a translog cost function to model production in the Irish manufacturing sector over the period from 1991 to 2009. We estimate both own- and cross-price elasticities and Morishima elasticities of substitution between capital, labour, materials and energy. We find that capital and energy are substitutes in the production process. Across all firms we find that a 1% rise in the price of energy is associated with an increase of 0.04% in the demand for capital. The Morishima elasticities, which reflect the technological substitution potential, indicate that a 1% increase in the price of energy causes the capital/energy input ratio to increase by 1.5%. The demand for capital in energy-intensive firms is more responsive to increases in energy prices, while it is less responsive in foreign-owned firms. We also observe a sharp decline in firms' responsiveness in the first half of the sample period."

Logging Occupancy to Optimize Energy Use - Energy Efficiency Markets - 2 views

  • Every occupant in a building creates demand for lighting, ventilation, thermal comfort, and electrical power. Lighting, heating, and cooling unoccupied spaces is a huge source of energy waste in buildings, and many studies have shown that building occupancy profiles have a significant impact on building energy use and operational controls.

    Closer alignment of occupancy patterns to building equipment schedules can be an effective low-cost/no-cost energy efficiency strategy leading to more intelligent control of buildings, a better balance between occupant comfort and energy savings, and lower utility bills. This includes, but is not limited to, HVAC temperature set points, lighting schedules, and economizer schedules.

Energy Harvesting the Next Big Thing for the Smart Grid | The Energy Collective - 0 views

  • Solar panels capture energy from light and convert it to electricity.   This is the most visible form of energy harvesting, but it is hardly the only one.  Energy harvesting captures energy lost as heat, light, sound, vibration, or movement.  Devices that harvest or scavenge energy can capture, accumulate, store, condition, and manage this energy into electricity for consumption.  That’s important, because our existing electricity infrastructure is extremely wasteful in its use of energy.  For instance, today’s technologies used in electricity generation are not energy efficient.  Traditional gas or steam-powered turbines convert heat to mechanical energy, which is then converted to electricity.  Up to two thirds of that energy input is lost as heat.  Those old incandescent bulbs (technology invented by Thomas Edison in 1879) were real energy losers too.  Ninety percent of the electricity flowing into incandescent bulbs ends up as waste heat. That’s lost energy, which is why smart federal legislation banned incandescents in favor of more energy efficient sources of lighting starting in 2012.

Clever MIT floating wind turbines can store power for when the wind doesn't blow : Tree... - 0 views

  • A single 25-meter sphere at a depth of 400 meters could store up to 6 megawatt-hours of power, so a large offshore wind farm with hundreds or even thousands of those could become a giant on-demand battery, potentially producing as much power as large power plants (it all depends on how far you scale up the idea). These anchor/storage spheres could be built on land and then brought out to sea. No need for too much super-expensive deep sea construction.

    Preliminary estimates indicate that one such sphere could be built and deployed at a cost of about $12 million, Hodder says, with costs gradually coming down with experience. This could yield an estimated storage cost of about 6 cents per kilowatt-hour — a level considered viable by the utility industry.

Battery Could Provide a Cheap Way to Store Solar Power | THE GREEN ENERGY BLOG - 0 views

  • 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”).
