New in Biofuel: Cellulosic Ethanol Plants to Ease Gas Consumption

Cars love inefficiently sucking down dead dinosaur juice, though hopefully for not much longer. In the meantime some companies have figured ways to produce cellulosic ethanol cheaply using more sustainable ways – basically a cheaper way to make biofuel for cars to burn on their way to wherever cars go.

Modern biofuels are better to use than dinosaur-based biofuels (which take millions of years to manufacture and I haven’t seen dinosaurs in years) so until we kick humanity’s gas addiction let’s use biofuels.

Novozymes, the world’s largest industrial enzyme producer, today launched a new line it says will yield ethanol from plant wastes at an enzyme price of about 50 cents a gallon. The latest product of a decade of research, this marks an 80 percent price drop from two years ago, according to Global Marketing Director Poul Ruben Andersen.

The advances, Andersen said, will help bring cellulosic ethanol production prices to under $2 a gallon by 2011, a cost on par with both corn-based ethanol and gasoline at current U.S. market prices.

Yesterday, Novozyme’s competitor, California-based Genencor, a division of enzyme giant Danisco, announced its own new enzyme product, which falls within a similar price range of about 50 cents to make a gallon of fuel, according to Philippe Lavielle, executive vice president of business development.

New Ankle That Recycles Energy

Here’s a neat idea: a body part that uses itself to propel itself.

ankle

We developed a microprocessor-controlled artificial foot that captures some of the energy that is normally dissipated by the leg and “recycles” it as positive ankle work. In tests on subjects walking with an artificially-impaired ankle, a conventional prosthesis reduced ankle push-off work and increased net metabolic energy expenditure by 23% compared to normal walking. Energy recycling restored ankle push-off to normal and reduced the net metabolic energy penalty to 14%.

Shipyards to Wind Farms

A proposal making the rounds in the UK calls for modifying shipyards (which aren’t doing so well in the current economy) into modern wind farms. A good reuse of industrial space.

On a visit to Newcastle, the Liberal Democrat leader said that disused shipyards should be upgraded to allow them to produce the new equipment.

Under a Lib Dem plan, all port authorities on the North Sea and Irish Sea would be able to bid for a share of a £400m pot to convert shipyards into wind turbine plants.

Clegg said: “We need to make sure we come out of this recession with a rebalanced and green economy.

“New offshore turbines, with blades the size of the London Eye, need to be built and launched from modern docks, so we need to upgrade our shipyards to take advantage of this massive opportunity.

“Just imagine the docks and shipyards along the coastline of Britain coming to life and leading the world in this new technology.

Hydrogen Challenger: Sustainable Energy on the High Seas

The Hydrogen Challenger is a tanker ship that has gone from 20th century ideas to storing 21st century hydrogen energy.

Hydrogen Challenger

From Wikipedia:
Hydrogen Challenger is a 66 meter (216′ 6″) refitted coastal tanker for mobile hydrogen production, it is fitted with a vertical axis wind turbine that generates electricity for the electrolysis of water to fill the hydrogen storage tanks. The total storage and transportation capacity is 1,194 m³ (42,000 ft3), it is stationed in the German Bight or near Helgoland (where the most wind is) and docks in Bremerhaven where the produced hydrogen is delivered to the market.

Distributed Solar Power Lights the Future

Large solar power installations require a lot of space and a lot of approvals. As a reaction to this, smaller solar power installations have been approved and placed close to transmission centres. This is a more reliable and sustainable energy network than what existed before.

Over the past few weeks, some 1,300 megawatts’ worth of distributed solar deals and initiatives have been announced or approved. At peak output, that is the equivalent of a big nuclear power plant.

Two weeks ago in California, regulators authorized the utility Southern California Edison’s program to install 500 megawatts of solar on commercial rooftops. A few days later, they recommended that Pacific Gas and Electric, the dominant utility in Northern California, be given the green light for its own 500-megawatt initiative that aims to install ground-mounted photovoltaic arrays near electrical substations and urban areas.

The Sacramento Municipal Utility District said in January that it took only a week to sell out its 100-megawatt solar program, which offers developers the opportunity to build photovoltaic projects of up to five megawatts.

And last week, the New York Power Authority announced a program to install 100 megawatts of solar arrays around the state.

“All of this is a great indication that solar prices are continuing to get a lot cheaper and that results in scale,” said Adam Browning, executive director of Vote Solar, a San Francisco nonprofit that promotes renewable energy.
