Audi highlights its range of electrification efforts; Q7 diesel PHEV, A7 fuel cell PHEV, BEV, 48V and more; 750 Wh/l by 2025

November 17, 2015

Audi presented a range of its ongoing work on electromobility and efficiency—from fuels and systems to full vehicles—under the “Future Performance Days 2015” banner.

On the full vehicle side, Audi put forward the Audi Q7 e-tron 3.0 TDI quattro plug-in hybrid (earlier post); the Audi A7 h-tron quattro fuel cell vehicle (earlier post); the Audi e-tron quattro concept battery-electric SUV (earlier post); the Audi TT clubsport turbo concept (earlier post); the Audi RS 5 TDI competition concept (earlier post); and the Audi R18 e-tron quattro (earlier post). On the systems and fuels side, Audi discussed battery technology; wireless charging; 48 V electrification (earlier post); Audi fuel cell technology; and Audi e-fuels (earlier post).

Ryder to fuel natural gas fleets in California with 100% biomethane from Clean Energy Fuels

November 12, 2015

Ryder System, Inc. and Clean Energy Fuels Corp. announced an agreement for Ryder to switch the fuel at their stations in Orange and Fontana, CA, to Clean Energy’s Redeem renewable natural gas (RNG)—i.e., biomethane. (Earlier post.) The fuel at the two stations will be available in both compressed natural gas (CNG) and liquefied natural gas (LNG) to individual and public fleet vehicles.

Clean Energy’s renewable natural gas vehicle fuel is derived from biogenic methane or biogas—methane that is naturally generated by the decomposition of organic waste. The methane gas is then processed, purified and sent into the interstate natural gas pipeline and made available exclusively to Clean Energy customers.

Audi e-gas plant qualified to participate in balancing market to stabilize grid

July 15, 2015

The Audi e-gas plant in the city of Werlte in Lower Saxony (earlier post) produces CO2 neutral-fuel (synthetic methane from water, renewable electricity and CO2); it now also contributes toward stabilizing the public power grid. After successfully completing a test sequence, the plant is now qualified for participating in the electricity balancing market.

In the German electrical energy mix, the share of renewable energies is growing rapidly, reaching 33% in the first half of 2015. However, regional expansion of wind and photovoltaic generation plants leads to increasingly larger load fluctuations. It is therefore important to have flexibly available consumers such as the Audi e-gas plant to buffer load peaks and thereby stabilize energy grids.

UPS enters agreement with Clean Energy Fuels for renewable natural gas (biomethane) in the US

May 05, 2015

UPS has entered into an agreement to purchase renewable natural gas (RNG) for its delivery vehicle fleet from Clean Energy Fuels Corp. RNG (biomethane) can be derived from many abundant and renewable sources, including decomposing organic waste in landfills, wastewater treatment and agriculture.

The deal signifies UPS’ plan to expand significantly its use of renewable natural gas for its alternative fuel and advanced technology fleet. The company has a goal of driving one billion miles using its alternative fuel and advanced technology fleet by the end of 2017. Clean Energy Fuels, co-founded by T. Boone Pickens, is the exclusive producer of Redeem, the first RNG made available in commercial quantities.

E3 study finds low-carbon gas fuels option for meeting Calif GHG reduction goals

January 28, 2015

A new study by Energy Environmental Economics (E3) consulting suggests that low-carbon gas fuels are a viable option for meeting California’s greenhouse gas (GHG) reduction goals and can simultaneously help achieve pollution emission reduction targets.

Low-carbon gas fuels or “decarbonized gas” refers to gaseous fuels with a net-zero, or very low, greenhouse gas impact on the climate. These include fuels such as biogas, hydrogen and renewable synthetic gases produced with low lifecycle GHG emission approaches.

California makes first investments in $100M energy research & development program; also biogas and H2

December 11, 2014

The California Energy Commission approved its first $10 million to fund Electric Program Investment Charge (EPIC) research and development (R&D) projects during its monthly business meeting today. The Commission also approved grants for the operation of a hydrogen fueling station, biofuel production, geothermal exploration and rooftop solar for schools.

EPIC is a multi-year, research investment program focused on electricity-related innovations, finding new energy solutions and bringing clean energy ideas to the marketplace. The program’s 2012-2014 plan calls for investing $330 million between 2014 and 2015 in innovative technologies that provide benefits to electric ratepayers served by Pacific Gas and Electric Co., Southern California Edison, and San Diego Gas & Electric Co. The seven awards approved will fund applied R&D projects that will develop utility-scale renewable energy generation technologies.
