NINO MARCHETTI, EarthTechling.com, May 27, 2010

A commercial wave-powered demonstration facility a mile off of Freeport, Texas in the Gulf of Mexico is on its way to being one of the first in the world to not only demonstrate the potentials of clean energy through wave power, but also showcase the desalination of salt water for clean drinking water via renewable ocean energy. The facility is to be managed by Independent Natural Resources, Inc. (INRI), through its wholly-owned subsidiary Renew Blue, Inc. (RBI)

INRI said it has gotten the go ahead from both the U.S. Army Corps of Engineers and the Texas General Land Office for the facility. Once online later this year, INRI’s wave power facility will use the company’s SeaDog pump system to capture both kinetic and potential energy using what is described as “a simple pump design with few moving parts and no electronics.” Some of the power being generated will be diverted into the fresh water desalinating process, which reportedly will be able to produce “up to 3,000 gallons of fresh water per day as a demonstration of its ability to provide clean water on a municipal scale.” It is believed a facility such as this could be capable of producing much more than that amount of drinking water as well if needed.

“It is an exciting time for us as we move closer to demonstrating a renewable energy technology that can provide base load electricity and fresh water for municipalities, commercial business and local entities,” said Douglas Sandberg, vice president for INRI.

The Federal Energy Regulatory Commission (FERC) and the State of California have signed a Memorandum of Understanding (MOU) to coordinate procedures and schedules for review of hydrokinetic energy projects off the California coast.

This marks the fourth hydrokinetics MOU that FERC has signed with other states, following agreements signed last year with Washington and Maine, and with Oregon in 2008. Today’s agreement ensures that FERC and California will undertake all permitting and licensing efforts in an environmentally sensitive manner, taking into account economic and cultural concerns.

“This agreement with California shows FERC’s continuing commitment to work with the states to ensure American consumers can enjoy the environmental and financial benefits of clean, renewable hydrokinetic energy,” FERC Chairman Jon Wellinghoff said.

“I am delighted the State of California has signed an MOU with the Commission on developing hydrokinetic projects off the California coast,” Commissioner Philip Moeller said. “This completes a sweep of the West Coast which, along with Maine, is showing its commitment to bringing the benefits of clean hydrokinetic energy to the consumers of the United States.”

FERC and California have agreed to the following with respect to hydrokinetics:

  • Each will notify the other when one becomes aware of a potential applicant for a preliminary permit, pilot project license or license;
  • When considering a license application, each will agree as early as possible on a schedule for processing. The schedule will include milestones, and FERC and California will encourage other federal agencies and stakeholders to comply with the schedules;
  • They will coordinate the environmental reviews of any proposed projects in California state waters. FERC and California also will consult with stakeholders, including project developers, on the design of studies and environmental matters; and
  • They will encourage applicants to seek pilot project licenses prior to a full commercial license, to allow for testing of devices before commercial deployment.

GAYATHRI VAIDYANATHAN, New York Times, March 2, 2010

Harnessing the ocean waves for emission-free power seems like a tidy concept, but the ocean is anything but tidy. Waves crash from multiple directions on a seemingly random basis, and converting the kinetic energy into electricity is a frontier of alternative energy research that requires grappling with large unknowns.

But with several utility companies and states, and in one case, the U.S. Navy, investing in wave power, or hydrokinetic energy, may not be too far off in the utility mix. At least two companies hope to reach commercial deployments within the next three to five years.

Off the coast of Orkney, Scotland, is the Oyster, a white- and yellow-flapped cylinder, 40 feet tall and firmly locked into the ocean’s bed. With a total of seven moving parts, two of which are pistons, it captures waves as they near the coast. Oyster funnels them into a pipe and carries the power inland to a hydroelectric power generator. The generator has been supplying the United Kingdom’s grid with 315 kilowatts of energy at peak power since October.

A farm of up to 100 Oysters could yield 100 megawatts, according to Aquamarine Power, the Scottish company that developed the technology.

“From an environmental perspective, in the sea you have a very simple machine that uses no oil, no chemicals, no electromagnetic radiation,” said Martin McAdam, CEO of Aquamarine.

The Oyster provides a tiny fraction of the 250 gigawatts of power that the water is capable of providing, including conventional hydroelectric energy by 2030, according to the United Nations. At least 25 gigawatts of that will come from marine renewables, according to Pike Research, a clean technology market research group. The non-conservative estimate is as much as 200 gigawatts. And 2015 will be the benchmark year to determine which of these estimates will be true.

The field of hydrokinetic power has a number of companies such as Aquamarine, all with unique designs and funded by utility companies, government grants and venture capitalists. If at least 50% of these projects come online by 2015, marine power could supply 2.7 gigawatts to the mix, according to Pike Research. A gigawatt is the electrical output of a large nuclear power plant.

‘PowerBuoy’ joins the Marines

There are six marine renewable technologies currently under development that aim to take advantage of ocean waves, tides, rivers, ocean currents, differences in ocean temperatures with depth, and osmosis.

“The energy landscape is going to be a mix of different energy sources, with an increasing proportion coming from renewables,” said Charles Dunleavy, CEO of Ocean Power Technologies, a New Jersey-based research group also developing wave energy. “We aim to be a very big part of this.”

The company has been testing its wave energy device, called the PowerBuoy, in the ocean since 2005. It recently launched another device a mile offshore from the island of Oahu in Hawaii and connected it to the power grid of the U.S. Marine Corps base. It now supplies 40 kilowatts of energy at peak, enough to power about 25 to 30 homes.

“The Navy wants to reduce its reliance on imported fossil fuel; they have a strong need to establish greater energy independence,” said Dunleavy.

The buoy captures the energy from right-sized waves (between 3 and 22 feet tall), which drive a hydraulic pump. The pump converts the motion into electricity in the ocean using a generator embedded into its base. A subsea cable transfers the power to the electrical grid. A buoy farm of 30 acres could yield 10 megawatts of energy, enough to supply 8,000 homes, said Dunleavy.

The structures rise 30 feet above water, and extend 115 feet down. They would not be a problem for commercial trawlers, which are farther offshore, or for ship navigation lanes, said Dunleavy. Recreational boaters, however, may have to watch out.

‘Oyster’ competes with the ‘top end of wind’

In comparison with a system such as the Oyster that brings water ashore to power turbines, creating electricity in the ocean is more efficient, said Dunleavy. “You lose a lot of energy to friction,” he said.

But Aquamarine’s system of having onshore power generation will cut down on maintenance costs, according to McAdam. Operation costs are expected to consume as much as 40% of the budget of operating a marine power plant, according to Pike Research.

Ocean Power is already selling its device for individual commercial use and building larger units of 150 kilowatts off the West Coast of the United States and for the utility company Iberdrola’s unit in Spain.

It is also developing the first wave power station under the Department of Energy’s stimulus program at Reedsport, Ore., according to Dunleavy. The farm, which currently has a 150-kilowatt unit, could grow by nine additional buoys.

And as for price, which is a major concern, Dunleavy said that cost compares with other renewables.

“It is cheaper than solar thermal and photovoltaics, and in the range of biomass,” he said. “It is at the top end of wind.”

The Oyster is also aiming to position itself as an alternative to wind power for utilities. McAdam said that by 2013, his company hopes to be a competitor to offshore wind installations. And by 2015, he hopes to compete with onshore wind.

FRANK HARTZELL, Mendocino Beacon, February 25, 2010

The Southern California investment company with a federal permit to develop wave energy in waters off Mendocino has entered into a partnership with one of the world’s top companies in the field.

GreenWave Energy Solutions recently entered into a memo of understanding, or MOU, with Ocean Power Technologies (OPT) of New Jersey, a move which makes wave energy off the village of Mendocino much more likely than ever.

Earlier this month, Ocean Power Technologies earned a federal license to develop wave energy off Reedsport, Ore., a groundbreaking move in the Federal Energy Regulatory Commission (FERC) process.

Ocean Power Technologies had its own FERC wave energy preliminary permit off Cape Mendocino but last year gave up on that site as impractical. OPT, which has since eclipsed many of its hydrokinetics competitors, plans to bring its experience to developing waters off Mendocino, the FERC permit states.

OPT recently deployed one of its Power Buoys off Hawaii, where it is also developing wave energy. OPT has been granted the exclusive right to sell their patented WEC devices to GreenWave for the generation of electrical power off Mendocino.

The existence of GreenWave’s FERC preliminary permit already spells doom for the creation of any new Marine Life Protection Act (MLPAI) Initiative protection of the claimed area.

GreenWave told FERC in its latest progress report that the firm has a target date of April 2012 for filing a license to actually develop electricity off Mendocino.

A preliminary permit gives exclusive study rights to an area to the applicant and also provides automatic preference to a license to actually produce power in the ocean.

“The proposed 100 megawatt GreenWave Mendocino Wave Park is estimated to generate an average of 250 GigaWatt-hours annually. GreenWave has contacted most or all of the stakeholders … and will continue to conduct community outreach and informational efforts to keep all stakeholders apprised of progress and plans related to the environmental studies and development of this proposed wave energy project,” the FERC filing by GreenWave President Wayne Burkamp states.

GreenWave and Ocean Power Technologies plan joint meetings locally beginning in March, the filing states. The two firms plan to file full details of the wave energy project with FERC by March and then discuss those plans in public meetings with locals.

Wave energy has generated substantial local opposition led by local fishermen. The environmental community in Mendocino has also opposed wave energy. Environmentalists in Humboldt County have not been involved in the issue.

PG&E, faced with local opposition, withdrew its Fort Bragg wave energy development application and continued its effort in friendlier Humboldt County, then added a second site in Southern California.

National environmental groups signed off on wave energy in a letter to president Obama. But the Obama administration studied the issue and, like Fort Bragg residents, learned the technology raised serious environmental issues and was too theoretical to help with the nation’s energy needs in the foreseeable future. In the meantime, fishing and civic groups have been seeking to construct a public process that protects the ocean.

A group formed in Fort Bragg, Fishermen Interested in Safe Hydrokinetics (FISH) is the lead plaintiff on a lawsuit against FERC challenging FERC’s issuance of the exclusive development rights to waters off Mendocino to GreenWave. The city of Fort Bragg, County of Mendocino, the Ocean Protection Council, the Pacific Coast Federation of Fishermen and the Recreational Fishing Alliance are also part of the challenge.

The lawsuit, with filings due in federal court this spring and summer, asserts that FERC failed to follow environmental laws or create a comprehensive plan before issuing wave energy permits.

“GreenWave has reviewed the allegations contained in the complaint and believes the allegations are without merit. GreenWave is monitoring this litigation and will provide any support that FERC believes necessary,” GreenWave’s recent filing states.

PG&E said the reason it abandoned its Fort Bragg development site was Noyo Harbor is unsuitable. That hasn’t discouraged GreenWave so far.

Background

The exclusive three-year preliminary permit granted in May 2009 to GreenWave stretches from just north of Albion to off Point Cabrillo, about a half-mile to three miles offshore.

Five men from the Thousand Oaks area of Southern California, including Tony Strickland, a Republican state senator, formed GreenWave Energy Solutions about two years ago.

Strickland, one of the state’s most ardent deregulators and anti-tax advocates, won the state Legislature’s closest race last November by a handful of votes, California’s closest major race. He made his involvement in alternative energy a key part of his campaign.

Green Wave Energy Solutions when formed was composed of Burkamp, Strickland, engineer Bill Bustamante and prominent housing developers Dean Kunicki and Gary Gorian.

Calls to GreenWave’s message phone number revealed Strickland and the others are still involved.

GreenWave does not mention Strickland, or any local members of the California Legislature among its communications with the Legislature in its report to FERC.

“GreenWave has participated in numerous meetings with California state government officials regarding various aspects of the permitting process and the political dynamics of development of a wave farm, in this district. GreenWave has met with various legislative personnel including California State Assemblyman Felipe Fuentes (39th District). Assemblyman Nathan Fletcher (75th District), and Gov. Schwarzenegger’s Chief Deputy Legislative Assistant, John Moffatt.

“These meetings involved discussions regarding the future of wave energy in California, working to streamline the permitting process in California and questions related to legislation which would assist in wave energy development,” the FERC filing states.

The Marine Life Protection Act Initiative process has concentrated solely on restricting and banning fishing, despite broader general ocean protection goals in the act. An opinion issued by the California Attorney General’s office states that any prior legal claim (such as a preliminary permit for wave energy) precludes the establishment of any type of new marine protected area. However, that fact has not yet been introduced into the discussions of creation of “arrays” or fishing restricted areas, despite large areas off limits in both Humboldt and Mendocino counties due to permits granted to PG&E and GreenWave.

PennWell Publishing, February 22, 2010

Construction has begun off Oregon’s coast on a commercial U.S. wave energy farm, which is being developed by Ocean Power Technologies and is planned to supply power to about 400 homes, according to national media reports.

The system will be installed off the Oregon coast near Reedsport, and it will represent the first phase of an expected 10-PowerBuoy Reedsport wave power station with a generating capacity of about 1.5 MW. The development would be the first commercial-scale wave power farm in the United States.

The first buoy will measure 150 feet tall by 40 feet wide, weigh 200 tons and cost $4 million, according to Phil Pellegrino, spokesman for New Jersey-based developer Ocean Power Technologies, Inc. OPT has chosen Oregon Iron Works to construct its first commercial wave energy PowerBuoy system in North America.

Nine additional PowerBuoys will be constructed and installed under the second phase of the project. The additional buoys are scheduled to be deployed by 2012 at a total cost of about $60 million.

Ocean Power Technologies recently received an A$66.5 million (US$61 million) grant from the Australian government to build a 19-MW wave power project off the coast of Victoria, Australia.

Ocean Power Technologies plans to complete its first PB150 wave energy device in the UK for deployment in Scotland in mid 2010.

JOHN UPTON, San Francisco Examiner, January 28, 2010

Tracking gray whales as they migrate past the San Francisco shoreline will help provide key information for a proposed plan to for a wave energy farm.

The mammals — which can grow up to 50 feet long, weigh up to 40 tons and are considered endangered on the West Coast — migrate between the Alaskan coast to the shores off Mexico, where they give birth to their young.

During their travels, the whales pass near Ocean Beach — but there is a lack of information about exactly where.

Moss Landing Marine Laboratories researchers will partner with San Francisco and track the mammals’ depth and distance from the shoreline using visual surveys and satellite tracking devices. A review of existing scientific literature will also be undertaken.

“There’s a fair amount of data on gray whales down around Monterey,” San Francisco Public Utilities Commission Project Manager Randall Smith said. “But there’s a data gap off the San Francisco coastline.”

The study will help city officials decide how and where to safely place an array of potentially-revolutionary underwater devices that might eventually deliver power as cheaply as solar panels.

The farm would capture and convert into electricity the power of arctic storm-generated waves as they pulse toward Ocean Beach.

A wide variety of devices are being developed worldwide that could help capture the wave power: Some bob near the surface, others float midwater like balloons, and a third type undulates like kelp along the seafloor.

Learning about gray whale migration patterns will help officials determine which devices would minimize the risk of whale collisions and decide where they should be located.

Research by UC Berkeley professor Ronald Yeung previously identified Ocean Beach as having strong potential for the nascent form of energy generation.

A wave study completed by San Francisco city contractors in December confirmed the site’s potential, according to Smith.

“Potentially, we could do a 30-megawatt wave farm out there,” Smith said.

The timelines and investment structure of the wave project are unclear, largely because the U.S. Minerals Management Service — which historically managed gas and oil deposits — was recently charged with regulating offshore renewable energy projects.

While the SFPUC waits for the service to finalize its permit application procedures, it’s forging ahead with an environmental review of the project required by California law, which includes the whale study.

Gray whales – the giant mammals are an endangered species.

Annual migration: 10,000 miles
Length: Up to 50 feet
Weight: Up to 80,000 pounds
Lifespan: In excess of 75 years
Maturity: Six to 12 years
Gestation: 12 to 13 months
Newborn calves: 14 to 16 feet long; 2,000 pounds

DAVID TOW, Future Planet, January 16, 2010

By 2015 India and China will both have outstripped the US in energy consumption by a large margin. Cap and Trade carbon markets will have been established by major developed economies, including India and China, as the most effective way to limit carbon emissions and encourage investment in renewable energy, reforestation projects etc.

There will have been a significant shift by consumers and industry to renewable energy technologies- around 25%, powered primarily by the new generation adaptive wind and solar energy mega-plants, combined with the rapid depletion of the most easily accessible oil fields. Coal and gas will continue to play a major role at around 60% useage, with clean coal and gas technologies still very expensive. Nuclear technology will remain static at 10% and hydro at 5%.

Most new vehicles and local transport systems will utilise advanced battery or hydrogen electric power technology, which will continue to improve energy density outputs.

Efficiency and recycling savings of the order of 30% on today’s levels will be available from the application of smart adaptive technologies in power grids, communication, distribution and transport networks, manufacturing plants and consumer households. This will be particularly critical for the sustainability of cities across the planet. Cities will also play a critical role in not only supporting the energy needs of at least 60% of the planet’s population through solar, wind, water and waste energy capture but will feed excess capacity to the major power grids, providing a constant re-balancing of energy supply across the world.

By 2025 a global Cap and Trade regime will be mandatory and operational worldwide. Current oil sources will be largely exhausted but the remaining new fields will be exploited in the Arctic, Antarctic and deep ocean locations.  Renewable energy will account for 40% of useage, including baseload power generation. Solar and wind power will dominate in the form of huge desert solar and coastal and inland wind farms; but all alternate forms- wave, geothermal, secondary biomass, algael etc will begin to play a significant role.

Safer helium-cooled and fast breeder fourth generation modular nuclear power reactors will replace many of the older water-cooled and risk-prone plants, eventually  accounting for around 15% of energy production; with significant advances in the storage of existing waste in stable ceramic materials.

By 2035 global warming will reach a critical threshold with energy useage tripling from levels in 2015, despite conservation and efficiency advances. Renewables will account for 60% of the world’s power supply, nuclear 15% and fossils 25%. Technologies to convert CO2 to hydocarbon fuel together with more efficient recycling and sequestration, will allow coal and gas to continue to play a significant role.

By 2045-50 renewables will be at 75-80% levels, nuclear 12% and clean fossil fuels 10-15%. The first Hydrogen and Helium3 pilot fusion energy plants will be commissioned, with large-scale generators expected to come on stream in the latter part of the century, eventually reducing carbon emissions to close to zero.

However the above advances will still be insufficient to prevent the runaway effects of global warming. These long-term impacts will raise temperatures well beyond the additional two-three degrees centigrade critical limit.

Despite reduction in emissions by up to 85%, irreversible and chaotic feedback impacts on the global biosphere will be apparent. These will be triggered by massive releases of methane from permafrost and ocean deposits, fresh water flows from melting ice causing disruptions to ocean currents and weather patterns.

These will affect populations beyond the levels of ferocity of the recent Arctic freeze, causing chaos in the northern hemisphere and reaching into India and China and the droughts and heat waves of Africa, the Middle East and Australia.

The cycle of extreme weather events and rising oceans that threaten to destroy many major coastal cities will continue to increase, compounded by major loss of ecosystems, biodiversity and food capacity. This will force a major rethink of the management of energy and climate change as global catastrophe threatens.

Increasingly desperate measures will be canvassed and tested, including the design of major geo-engineering projects aimed at reducing the amount of sunlight reaching earth and reversal of the acidity of the oceans. These massive infrastructure projects would have potentially enormous ripple-on effects on all social, industrial and economic systems. They are eventually assessed to be largely ineffective, unpredictable and unsustainable.

As forecasts confirm that carbon levels in the atmosphere will remain high for the next 1,000 years, regardless of mitigating measures, priorities shift urgently to the need to minimise risk to life on a global scale, while protecting civilisation’s core infrastructure, social, knowledge and cultural assets.

Preserving the surviving natural ecosystem environment and the critical infrastructure of the built environment, particularly the Internet and Web, will now be vital. The sustainability of human life on planet Earth, in the face of overwhelming catastrophe, will be dependent to a critical degree on the power of the intelligent Web 4.0, combining human and artificial intelligence to manage food, water, energy and human resources.

Only the enormous problem-solving capacity of this human-engineered entity, will be capable of ensuring the continuing survival of civilisation as we know it.
