Infographic: biomass feedstock and the supply chain

with one comment


Genera recently published an infographic overview of different biomass feedstocks and guidelines for choosing the best solution for every biomass project. The infographic highlights key supply chain elements and explores which biomass crops are best suited for an application.

While not comprehensive to all feedstocks, the document gives customers, stakeholders, and policy makers a better understanding of the unique dynamics associated with biomass feedstocks.

Genera says choosing the right feedstock or feedstock portfolio is critical to the success of any project. “In many cases, raw feedstock is 50 percent or more of the total cost of producing renewable biofuels and biochemical. Optimizing a project’s feedstock portfolio has a significant impact on profitability.”

NRDC airline scorecard ranks airline biofuel use

with one comment


NRDC aviation biofuel picHere’s the deal: air travel emissions pump more than 650 million metric tons of carbon pollution into the air each year – that’s equivalent to the pollution from 136 million cars. It’s not likely that airplanes will go away anytime soon, which makes the increased use of sustainable biofuels critical to reducing the industry’s carbon footprint.

According to a first-of-its-kind scorecard released earlier this month by the Natural Resources Defense Council, “the industry is making strides in adopting sustainable biofuels, with some airlines doing better than others as they incorporate these new fuels into their fleets. Air France/KLM is by far the leader of the pack.”

Debbie Hammel, senior resource specialist with NRDC’s Land & Wildlife Program and author of the scorecard, As the world rises to the challenge of curbing climate change and cutting carbon pollution, addressing air travel pollution has to be part of the mix. The aviation sector has been pretty proactive about this issue, and an industry-wide increase in the use of sustainably produced biofuels is definitely on the horizon.”

NRDC’s Aviation Biofuel Sustainability Scorecards evaluated airlines’ adoption of biofuels, focusing on the use of leading sustainability certification standards, participation in industry initiatives to promote sustainability certification, public commitments to sustainability certification in sourcing, and the monitoring and disclosure of important sustainability metrics.

Port of San Francisco urged to restrict fossil fuels

leave a comment »


portofsf_jeremyredingThe San Francisco Board of Supervisors is urging the Port of San Francisco and the city’s Department of the Environment to develop policies that will bar the transportation and export of hazardous fuel materials in San Francisco.

Supervisors Malia Cohen and Scott Wiener introduced the resolution to prohibit the movement of crude oil, coal, and petroleum coke (petcoke) through San Francisco, citing safety concerns, dangers to the environment, public-health hazards, economic pitfalls, and public opposition. The resolution passed the board unanimously last week.

“San Francisco has always been known as a city at the forefront of environmental change. This resolution barring the handling of polluting, climate-warming fuels proves yet again that it is a city that leads the world in envisioning a better way to live,” said Stacey Geis, Earthjustice managing attorney of the California office.

Less is more, more or less: Matt Ridley’s strange alchemy

leave a comment »


alchemyMatt Ridley, the UK author, journalist and member of the House of Lords, recently asserted in a Wall Street Journal article that the “world’s resources aren’t running out.” Well maybe, sorta. If you are into the mental gymnastics of conservative doublethink.

I could not let his piece pass without providing, shall we say, a different and more intellectually honest (I hope) viewpoint.

He asks: “How many times have you heard that we humans are ‘using up’ the world’s resources, ‘running out’ of oil, ‘reaching the limits’ of the atmosphere’s capacity to cope with pollution or ‘approaching the carrying capacity’ of the land’s ability to support a greater population? The assumption behind all such statements is that there is a fixed amount of stuff—metals, oil, clean air, land—and that we risk exhausting it through our consumption.” Read the rest of this entry »

Airbus electric aircraft flies

with 2 comments


E-Fan Technology Demonstrator (2)_loRecently I wrote about Boeing’s all-electric satellite, which might launch later this year. Not to be outdone, apparently, Airbus Group flew the first all-electric aircraft late last month, called the E-Fan.

The E-Fan is an all-electric trainer aircraft made of composite material.

Leaving jet fuel behind means there is slight hitch: at the moment the the plane can fly for about an hour on a single charge. In any case this is a pretty big deal, because the largest aerospace and defense company in Europe and the world’s leading commercial aircraft manufacturer is backing it, is planning to build the trainer in series and is also planning to use what it learns to eventually develop a regional passenger model.

Boeing putting something electric in space

with one comment


??????All-electric satellite propulsion is getting a boost from Boeing, which says it is “on track” to deliver the world’s first all-electric xenon-ion propulsion satellites in late 2014 or early 2015 after meeting key production milestones on its initial 702SP (small platform) satellites.

Boeing announced that it has completed static qualification testing, verification and assembly of the primary structures for 702SP inaugural customers ABS and Eutelsat, meaning the satellites are well on their way to launch. The initial contract for the satellite was signed in 2012 between Boeing and Satmex. Eutelsat acquired Satmex in January 2014.

The four 702SP communications satellites will launch in pairs, and once in orbit, they will be entirely powered and propelled by electricity, rather than relying on rockets. The first two are scheduled for launch aboard a single SpaceX Falcon 9 rocket early next year. An all-electric satellite dispenses with heavy chemical propulsion and uses electric propulsion not only to maintain itself stably in orbit over 15 years, but also to raise the satellite from where it is dropped into orbit by its carrier rocket to its final destination in geostationary orbit.

Seattle, Tacoma get EPA grants for clean diesel initiatives

leave a comment »


Mt Rainier over Port of SeattleThe ports of Seattle and Tacoma received nearly $2 million In grants under a new Environmental Protection Agency initiative that recognizes U.S. ports for improving environmental performance and sustainability.

It’s a great move because port areas generate some of the worst diesel emission problems in the nation, whether it’s from the cargo ships that dock at terminals without powering down their engines, the terminal equipment that services the ships, or the hundreds of trucks moving to and from terminals to load and unload the cargo.
