ABS moves a step closer to OTEC (ocean thermal energy conversion) certification for the OTI design

From the October 2011 issue of (IMarEST) Marine Engineering Review:

American Bureau of shipping (ABS) class society has issued AIP (Approval in Principle) for the version of the ocean thermal energy conversion (OTEC) system developed by the company OTEC International LLC.

Key elements evaluated by ABS include: spar hull sizing for the deep draft spar design; energy conversion equipment located in the spar; handling and storage of hazardous materials; deepwater mooring system; cold water pipe conduit suspended from the base of the spar; construction and attachment of the cold water pipe conduit; and power transmission cable with its securing, anchoring and suspension arrangements. ABS reviewed the design for an extended 30-year facility on-station life.

ABS has issued Approval in Principle for both the 25MW and 100MW designs; OTI could be eligible for ABS’ class notation A1, Floating Offshore Installation (FOI) Spar, SFA(30).

Some more information is available on the OTI site

I consider the involvement of a classification society very good news.

In effect a confirmation from a third party that the technology is fundamentally sound.

Quite a fundamental requirement if we want this to eventually become a commercial success, right?

In our blog we previously covered some other OTEC projects here:

OPT Powerbuoy deployed in Hawaii

Ocean Power Technologies, Inc. announcement of deployment of one PowerBuoy wave energy device at the Marine Corps Base at Kaneohe Bay on the island of Oahu, Hawaii.

The announcement continues by saying that the location is “approximately one mile offshore in 100 feet of water” and that it is “generating power in accordance with its specifications for local wave conditions and the test protocol being used” not sure what that means, maybe a military secret… :)

In any case this seems to be a new enhanced PowerBuoy model with “a more efficient power take-off system”, OPT says.

The announcement also mentions on-going collaboration between OPT and the US Navy with more installations in the pipeline.

US Offshore Wind Project Updates | RenewableEnergyWorld.com

The U.S. has made great strides in installing renewable energy projects in the last five years. Renewables account for a larger percentage of U.S. energy generation than ever before and the country has surpassed Germany to lead in installed wind capacity worldwide. Germany and its European neighbors however remain far ahead of the U.S. when it comes to taking advantage of offshore wind resources. That may change in the next few years however as the U.S. regulatory, political and business climate becomes more friendly to wind developers looking to go offshore.

Possibly the largest challenge facing U.S. offshore wind energy developers however is the lack of a stable policy and incentive regime that would bring more players into the industry.

The American Wind Energy Association (AWEA) held its Offshore Wind Workshop earlier this month in Boston to look at the progress that has been made for U.S. offshore wind and what hurdles are left to overcome before the first turbine hits the water.

Project Updates

But just which project will get that first turbine in the water is still a matter of speculation. In total there are four companies with more than 10 projects in different states of development. Each company — Cape Wind, Bluewater Wind, Fisherman’s Energy and Deepwater Wind — is developing projects on the East Coast.

The most well-publicized and possibly controversial offshore wind project in the U.S. is Cape Wind. The project, which has spend eight years in development, would put turbines in Massachusetts’ Nantucket Sound. The project had a lot of opposition to overcome, first from residents in towns on the sound worried it would ruin their views and lead to higher electricity prices, and later from environmental groups concerned with the wildlife impact. These issues have since been addressed.

More recently, a group of Native Americans have said the project would obscure the view from an ancient burial ground, this issue is working its way through the regulatory process and is expected to be resolved by the end of 2009.

Not all of the news about Cape Wind has been negative however. The project was given a favorable Environmental Impact Statement from the U.S. Minerals Management Service, its grid connection in Barnstable, Massachusetts was approved by the Massachusetts Citing Board and National Grid has said that it will negotiate a power purchase agreement for the electricity the project might one day produce.

Jim Gordon, president of Cape Wind said that he thinks the U.S. will see an offshore wind project realized sooner rather later and its one of the keys to fighting the effects of climate change, especially for East Coast cities like Boston where trillions of dollars worth of infrastructure could be damaged or destroyed by rising seas and stronger storms that would be a result of climate change and an economy that needs to put people back to work to grow.

“Right now if Cape Wind was operating we would be producing 422 megawatts of clean renewable energy. That’s 422 megawatts of emissions free power that blows off our coast that will be harnessed by workers from this region,” Gordon said. “The Natural Resources Defense Council has said that Cape Wind represents one of the largest single greenhouse gas reduction initiatives in the United States. We’ve missed out these many years on mitigating many tons of greenhouse gases, but I believe and I hope that the American offshore wind industry is no going to emerge and reach its full potential.”

While Massachusetts has been the first stand of sorts for offshore wind, Delaware might be the spot of the industry’s first major victory. Bluewater Wind, formerly owned by Babcock and Brown, and now a subsidiary of NRG Energy, has leases in place and is set to deploy a series of meteorological (met) towers to determine the best sites for turbines in 2010.

The company also has one 200-MW PPA in place with Delmarva Power and has been selected to provide 55 MW of power to the state of Maryland under a PPA. Bluewater CEO Peter Mandelstam said that the company has interconnection agreements in place and also begun the federal permitting process.  He said the process is easier now as a result of the Obama Administration’s renewable energy goals.

“The most important investor, the most important advocate and the most important public official for offshore wind is President Barack Obama. This industry was dead, but the restructuring of the tax credit, the loan guarantees, the various stimulus provisions and the new regulatory regime totally revived us. We can’t say enough good things about President Barack Obama. He mentioned our Delaware project on Earth Day and going into Copenhagen, he talked about offshore as one of his six pillars to mitigating climate change,” Mandelstam said.

Two other development companies, Fishermen’s Energy and Deepwater Wind are taking different approaches to developing offshore wind projects.

Fishermen’s Energy is taking what it calls a community-based approach to offshore wind. The company was founded by leading Northeast commercial fishing companies so that they could be part of and benefit from the emerging offshore renewable energy industry. The company’s CEO Dan Cohen said that commercial fishing executives knew there was a need for workers to do the construction, operations and maintenance for offshore wind projects, jobs uniquely suited to commercial fishermen who already work offshore and the know waters.

Fisherman’s is involved in two projects: the first is a 350-MW project that the company plans to work on in conjunction with Bluewater Wind and Deepwater Wind. The second is demonstration project located in the waters just off the coast of Atlantic City, New Jersey. This 20-MW project is expected to be built by 2012 and rules for the build out of this project are currently drafted by the New Jersey Board of Public Utilities.

Deepwater Wind plans to do exactly what’s implied by its name, namely build projects 15-20 miles offshore, minimizing the impact of not-in-my-backyard (NIMBY) protests and taking advantage of the stronger wind regimes in those waters. The company has been awarded met tower leases and plans to put them in the water in the next year.

Deepwater, which is part of a consortium developing a project in the waters off Long Island, expects that its first project in the water will be the 30-MW Block Island project off the coast of Rhode Island, which is still pending federal approval. In conjunction with this project, the company is also working to develop Quonset Point, a former U.S. Navy base, into a dedicated offshore wind development hub for the Southern New England area.

Hurdles Still to Overcome

Some challenges remain however. First and foremost is the lack of the vessels needed to install these projects. There are currently no vessels in the U.S. equipped to install these turbines, and while a number of them exist in Europe they cannot simply be brought across the Atlantic Ocean and put to work.

The Jones Act precludes any European based specialty vessel from taking part in commerce in U.S. waters, including the installation of offshore energy projects. While many have suggested that ships used by the oil industry could simply be converted, the cost would likely be prohibitive and U.S. ship builders will have to build wind specific vessels, which Mandelstam said will create thousands of jobs for ports and ship builders that take advantage of the need.

“Seven thousand seven hundred green jobs would be created by building three turbine installation vessels,” he said. “As chairman of the offshore group in the U.S., I participated during the Bush Administration to analyze how we’d get to 20% wind, including 54,000 MW of offshore wind. The choke point is vessels. The Obama Administration has put up a TIGER Grant and the Philadelphia Regional Port Authority has applied and we may gain access to those vessels if there’s an announcement in February 2010.”

Like any other renewable energy or conventional generating assets, in order for offshore wind projects to be built they will need transmission lines and utilities willing to buy the electricity they carry. In some ways this is where the U.S. industry is putting the cart before the horse.

Transmission plans are already underway within the ISO New England region to bring tens of gigawatts of wind power online and the ISO has produced a report for New England’s Governors Association presenting them with a number of scenarios that would bring offshore wind energy to residents of New England.

Even though this transmission capacity is still in the planning stage, utilities are lining up to buy the power once its online. Delmarva Power, National Grid, the state of Maryland and the Long Island Power Authority have already signed power purchase agreements (PPAs) with developers. The biggest advantage that utilities and ISO New England are looking at is the location of offshore wind resources. Who pays for it however remains the big question.

Gordon van Welie, president of ISO New England said that while his company has made a number of transmission investments onshore, they need to wait for a national renewable energy and transmission plan to be in place before a scenario from their report to governors, most likely costing around $6 billion, is chosen and invested in.

“The rhinoceros in the room is the transmission cost allocation,” Welie said, referring to the fact that who pays for the $6 billion in transmission will depend on who is thought to be getting the most benefit from its installation and costs are likely to be split between project developers, grid operators and utilities.

Possibly the largest challenge facing U.S. offshore wind energy developers however is the lack of a stable policy and incentive regime that would bring more players into the industry, from all sides. No matter the policy, be it feed-in tariff, production tax credit, cash grants or renewable energy credits, developers, financiers, utilities and grid operators are calling for more stable incentives and policies.

Long term policy surety would give banks more confidence investing in infrastructure, transmission, construction operations and maintenance vessels as well as generating equipment. Rhode Island Governor Donand Carcieri, who serves as vice chairman of the Governors’ Wind Energy Coalition said that while the states are leading the way, a federal standard is needed to move forward.

“Offshore wind power is one of the most reliable and sustainable sources of energy in the United States, and we are on the path to develop this nation’s first deep water, offshore wind project,” Governor Carcieri said. “The impact of offshore wind is tremendous, from spurring economic development and new jobs to providing stable energy costs, and will move our country towards energy independence.”

First U.S. Hydrokinetic Project Begins Commercial Operations | EERE News

August 26, 2009

First U.S. Hydrokinetic Project Begins Commercial Operations

The first federally licensed in-stream hydrokinetic power project in the United States began operating commercially on August 20 on the Mississippi River in Hastings, Minnesota. Hydrokinetic projects produce power from moving water without the use of a dam, and they include wave energy systems and in-stream turbines, which can capture the energy from tidal flows or the flow of a river. The Hastings project, an in-stream turbine from Hydro Green Energy, captures the flow from the output channel of an existing hydropower dam.

The turbine, anchored downstream from the dam on a tethered barge, has a nameplate capacity of 100 kilowatts, and an expected output of about 35 kilowatts. After approval of the project by the Federal Energy Regulatory Commission (FERC) last December, the turbine was quickly installed on the barge and has been undergoing testing since mid-February. The turbine was evaluated for its impact on fish in the river, and an environmental research firm’s pre-installation model estimated that 97.5% of fish passing through the turbine would survive the journey. Actual results of a June test, not yet publicly released, were higher, the company says. A second turbine with increased power and efficiency is slated to come online next spring. See the Hydro Green Energy press release (PDF 310 KB).

Hydrokinetic power is also making waves in Maine, which has become the first East Coast state to sign a Memorandum of Understanding (MOU) with FERC relating to the energy source. Maine agreed on August 19 to coordinate with the federal commission on tidal power projects off its coast. The MOU establishes Maine’s support of FERC’s procedures for a short-term license for experimental pilot projects. FERC and Maine also agreed to notify each other of proposed tidal energy projects and will work together to identify potential issues and to set a schedule to process permit applications. FERC had previously signed similar hydrokinetic agreements with the states of Oregon and Washington. See the FERC press release and the full MOU (PDF 370 KB).

Exxon Mobil to Invest in Oilgae | Energy Business Daily

Exxon Mobil to Invest in Oilgae
The international oil giant Exxon Mobil, whose chief executive had been infamous for mocking ethanol, one of the alternative energies as “moonshine,” is poised to enter in the field of biofuels. Exxon is going to announce investment of $600 million in producing liquid transportation fuels from algae — organisms in water found from pond scum to seaweed. They plan to tie up with Synthetic Genomics, the biotechnology company founded by the genomics pioneer J. Craig Venter.

The agreement is likely to address a major flaw in the strategy of the world’s largest and richest oil company, which had hitherto been criticized by environmentalists for being indifferent to global warming and also being reluctant to develop renewable fuels.

According to one of its prominent research analyst, despite the infamous “moonshine” remark a few years ago by its chairman and chief executive, Rex W. Tillerson, the company has spent many years exploring various fuel alternatives.

Vice President Emil Jacobs at the R&D of Exxon’s research and engineering unit stated that they have looked at every option keeping in mind several parameters, especially scale as if one is unable to scale up a technology then one should not get involved at all according to him. He added that it is easier said than done as production of algae-based fuels in commercial scale is still 5-10 years from now.

Environmentalist are definitely going to question the company’s sincerity and commitment considering Exxon’s huge profits from petroleum in the recent years. Kert Davies, research director at Greenpeace agrees about the need for new products in the market but doubts about the sincerity of big oil companies to put substantial efforts. Exxon’s move into biofuels, so far the preserve of venture capital and biotech firms, is likely to be a shot in the arm for the US administration.

Presently nine percent of Envi liquid fuel is derived from corn-based ethanol. Congress intends to push it up to the level of 36 billion gallons by 2022.

Being tricky, Mr. Tillerson’s skepticism about development of biofuel is not unfounded. Corn-based ethanol due to its low energy content and dubious environmental record had been the subject of severe criticism from many quarters. Exxon’s estimate is algae will yield yearly about 2,000 gallons of fuel per acre of production compared to 650 gallons for palm trees, 450 gallons for sugar canes and 250 gallons for corn.

Exxon’s tie up with Synthetic Genomics has also boosted the work of Dr. Venter, known for decoding the human genome in the 1990s, who has been working to find micro-organisms to turn in to fuel. In Dr. Venter’s opinion algae is the ultimate biological system capturing sunlight to convert carbon dioxide into fuel.

Algal biofuel aka oilgae by environmentalists, is a promising technology as fuels extracted would have same molecular structures like petroleum products including gasoline, diesel and jet fuel which will be compatible with present transportation infrastructure which has been proven by an algae-based fuel powered test flight by Continental Airlines.

Pentagon has also evinced interest in alternative fuels like algae to reduce its oil dependency.

Although cost-effective mass production is still far, algae’s advantages over other biofuels in growing them in areas unsuited for food crops or in brackish water or even sea water is considerable. Possibility of algae cutting down greenhouse gases is enormous. Exxon along with Synthetic Genomics plans to pioneer a genetically modified variety to absorb huge quantity of carbon dioxide like those emitted by power plants.

Exxon’s plans investment of $300 million for in-house studies and another $ 300 million for successfully meeting research and development milestones. Although a modest sum considering Exxon’s earning of $45.22 billion last year, the companies are projecting their partnership as a long-term R&D effort with possible investment running into billions.

Joule Biotechnologies Introduces Revolutionary Process For Producing Renewable Transportation Fuels

Two years into development, innovative startup enables path to energy independence; Unveils proprietary production system capable of supplying unlimited quantities of renewable fuel at costs competitive with fossil fuels

Cambridge, Mass.—July 27, 2009—Joule Biotechnologies, Inc., an innovative bioengineering startup developing game-changing alternative energy solutions, today unveiled its breakthrough Helioculture™ technology—a revolutionary process that harnesses sunlight to directly convert carbon dioxide (CO2) into SolarFuel™ liquid energy. This eco-friendly, direct-to-fuel conversion requires no agricultural land or fresh water, and leverages a highly scalable system capable of producing more than 20,000 gallons of renewable ethanol or hydrocarbons per acre annually—far eclipsing productivity levels of current alternatives while rivaling the costs of fossil fuels.
 
“There is no question that viable, renewable fuels are vitally important, both for economic and environmental reasons. And while many novel approaches have been explored, none has been able to clear the roadblocks caused by high production costs, environmental burden and lack of real scale,” said Bill Sims, president and CEO of Joule Biotechnologies. “Joule was created for the very purpose of eliminating these roadblocks with the best equation of biotechnology, engineering, scalability and pricing to finally make renewable fuel a reality—all while helping the environment by reducing global CO2 emissions.”

Joule’s transformative Helioculture process leverages highly-engineered photosynthetic organisms to catalyze the conversion of sunlight and CO2 to usable transportation fuels and chemicals. The scalable SolarConverter™ system facilitates the entire process—from sunlight capture to product conversion and separation—with minimal resources and polishing operations. This represents a significant advantage over biomass-derived biofuels, including newer algae- and cellulose-based forms, which are hindered by varying obstacles: costly biomass production, numerous processing steps, substantial scale-up risk and capital costs.

The modular SolarConverter design is engineered to meet demand on a global scale while requiring just a fraction of the land needed for biomass-based approaches. It can be easily customized depending on land size, CO2 availability and desired output. The functionality is proven and can readily scale from smaller operations with limited land to extensive commercial plants. Additional benefits enabled by the system include:

  • Multiple Product Lines—The same conversion technology and modular system used to produce SolarFuel liquid energy will also enable the production of SolarChemical™ products, several of which have already been demonstrated at laboratory scale.
  • Optimal Storage of Solar Power—Because Joule harnesses the sun to produce energy in the form of liquid fuel, it overcomes a major obstacle to the broad-based use of solar power, namely storage. SolarFuel liquid energy has up to 100 times the energy storage density of conventional batteries, and can be very efficiently stored and transported with no degradation of power.

“Today’s leading scientists and engineers have been called upon to solve one of the greatest challenges of our time: how to take promising theories and turn them into real, impact-making strides towards energy independence,” said Noubar Afeyan, founder and chairman of Joule Biotechnologies. “Joule is doing exactly thatcreating an entirely novel solution that combines the best of solar energy and biofuels, while eliminating their respective weaknesses. The result is a system that can operate at very large scale and provide efficient conversion and storage of solar power without relying on fossil or agricultural products as raw materials.”

Joule SolarFuel liquid energy meets today’s vehicle fuel specifications and infrastructure, and is expected to achieve widespread production at the energy equivalent of less than $50 per barrel. The company’s first product offering, SolarEthanol™ fuel, will be ready for commercial-scale development in 2010. Joule has also demonstrated proof of concept for producing hydrocarbon fuel and expects process demonstration by 2011.
