CarboSax: new joint venture for more sustainable carbon fiber production forms in Germany

October 13, 2016

PD Glasseiden, a Germany-based producer of fiberglass; European Carbon Fiber GmbH; and the ForschungsCampus Open Hybrid LabFactory e.V., established under the auspices of the Lower Saxony Research Centre for Vehicle Technology at the TU Braunschweig and Volkswagen AG have formed a joint venture—CarboSax GmbH—to pursue developing, manufacturing and distributing more sustainable carbon fibers in Germany.

In the first step at a location in Chemnitz, Saxony, CarboSax will build a pilot line for the sustainable production of carbon fibers. The objective of this carbon fiber pilot line production is a significant reduction in production costs by 30% over currently available commercial carbon fibers. This cost reduction is required to further enable the use of carbon fiber in mass production in the automotive industry, mechanical engineering and wind power. An equal objective is a reduction of at least 50% in CO2 emissions from carbon fiber production.

Siluria Technologies and Air Liquide partner to develop and deliver novel catalytic process technologies to global energy markets

June 07, 2016

Siluria Technologies has entered into a strategic partnership with Air Liquide Global E&C Solutions, the engineering and construction business of the Air Liquide Group, to collaborate on the development of novel catalytic processes utilizing both companies’ expertise in gas conversion technologies.

The novel process offering will be developed using the proven innovation platform that has given rise to Siluria’s revolutionary Oxidative Coupling of Methane (OCM) technology (earlier post), but will be focused on entirely new fields beyond the companies’ current product offerings. Siluria and Air Liquide Global E&C Solutions have agreed to work as partners in the commercialization—including marketing and licensing—of the jointly developed process technologies resulting from the collaboration.

Santa Monica signs 5-year deal with Clean Energy for renewable LNG for bus fleet; deploying CWI Near-Zero NOx engine

June 02, 2016

The City of Santa Monica, California has awarded Clean Energy a multi-year liquefied natural gas (LNG) contract to fuel its Big Blue Bus (BBB) fleet of vehicles. The 5-year deal, worth an estimated $3 million per year, will enable BBB to continue using Clean Energy’s Redeem brand of renewable natural gas (RNG), rated up to 90% cleaner than diesel. BBB began using Redeem by Clean Energy in January 2015. (Earlier post.)

BBB, one of the first transit agencies in the nation to contract for Redeem, will also become one of the first agencies to incorporate the new Cummins-Westport 8.9L ISL G Near-Zero 0.02 NOx engine, the first mid-range engine in North America to receive emission certifications from both US Environmental Protection Agency (EPA) and Air Resources Board (ARB) in California that meet the 0.02 g/bhp-hr optional Near Zero NOx Emissions standards. (Earlier post.) ARB has defined this certified Near Zero NOx emission level as equivalent to a 100% battery truck using electricity from a modern combined cycle natural gas power plant.

CNG Fuels and National Grid unveil first high-pressure grid-connected CNG filling station; biomethane option

March 21, 2016

UK-based CNG Fuels, in partnership with National Grid, has unveiled a new state-of-the-art filling station in Leyland, Lancashire, allowing vehicles to fill up on compressed natural gas (CNG) directly from the high-pressure local transmission system.

The new facility is the first of its kind in the UK and features a high-pressure connection, delivered by National Grid. This key piece of transport infrastructure is capable of refueling more than five hundred HGVs per day. The first major customer, Waitrose, part of the John Lewis Partnership, filled up at the new facility at unveiling, as a fleet of branded heavy-duty trucks rolled onto the forecourt.

New HPAC lignocellulose pretreatment method could accelerate cellulosic biofuel production

December 28, 2015

A team from Chonnam National University in Korea has developed a new pretreatment method for lignocellulosic biomass that is more efficient and effective for the downstream biocatalytic hydrolysis of various lignocellulosic materials. This, they suggest, will accelerate bioethanol commercialization.

The new hydrogen peroxide (H2O2)-acetic acid (CH3COOH) (HPAC) pretreatment removes lignin without the use of high temperatures or strong acids. It can be applied to multiple lignocellulosic materials; reduces enzyme loading and downstream enzymatic hydrolysis time; and lowers generation of fermentation inhibitors during the process. An open-access paper on the process is published in the journal Biotechnology for Biofuels.

FuelCell Energy pathway for hydrogen from digester gas has negative carbon intensity for CA LCFS

December 23, 2015

Connecticut-based FuelCell Energy (FCE) has applied for a prospective pathway for California’s Low Carbon Fuel Standard (LCFS) for the production of hydrogen fuel produced from biogas derived from the mesophilic anaerobic digestion of wastewater sludge at a publicly owned treatment works (POTW).

The biogas is cleaned, then internally reformed in an integrated hydrogen energy system (Tri-Gen DFC) that produces hydrogen fuel for transportation; electric power for plant operations and export; as well as thermal energy for plant use. Once the internal energy demands of the pathway have been met, any energy not utilized for process is considered to be surplus to the system boundary and is credited to the FCE pathway.

UPS to use biomethane for Memphis and Jackson alternative fuel fleet

December 21, 2015

UPS will supply its fleet in Memphis, Tenn., and Jackson, Miss., with an estimated 15 million diesel gallon gas equivalents of renewable natural gas (RNG)—biomethane—as part of a multi-year agreement with Memphis Light, Gas and Water and Atmos Energy Marketing, LLC.

Atmos will secure landfill gas and provide it to MLGW for conversion to LNG, which will be delivered to the UPS facility by tractor-trailer. The deal is part of an initiative announced earlier this year by UPS to significantly expand its use of renewable natural gas in UPS’s alternative fuel and advanced technology fleet. The company has a goal of driving one billion miles with its alternative fuels fleet—known as the Rolling Laboratory—by the end of 2017.

Hydrogen from biomethane; gasoline & diesel from tree residue; cellulosic ethanol among new proposed California LCFS fuel pathways

December 18, 2015

California Air Resources Board (ARB) staff posted 32 new Low Carbon Fuel Standard (LCFS) fuel pathway applications for comments at the LCFS website. Among the multiple applications for different processing pathways of corn or sorghum ethanol are four pathways from LytEn for hydrogen produced from biomethane; four pathways for renewable gasoline and diesel produced from tree residue from Ensyn; and one application for cellulosic ethanol using corn stover feedstock from POET.

The LCFS is a regulation to reduce the carbon intensity (CI) of fuels sold in California by 10% by 2020. The LCFS applies to liquid and non-liquid fuels. If a product is above the annual carbon intensity target, the fuel incurs deficits. If a product is below that target, the fuel generates credits which may be used later for compliance, or sold to other producers who have deficits. So far, fuel producers are over-complying with the regulation. (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.
