The Associated Press reported Monday that the Bureau of Ocean Energy Management, Regulation and Enforcement said the companies are allowed to resume work at previously drilled wells. The government ordered that work on those wells be suspended after the Deepwater Horizon Gulf rig disaster last April and said it would require companies to complete environmental reviews before being allowed to drill.

For those companies that were in the midst of operations at the time of the deepwater suspensions (last spring), todays notification is a significant step toward resuming their permitted activity, said Michael Bromwich, bureau director.

The 13 companies that received the notice are: ATP Oil Gas Corp.Chevron USA Inc.Cobalt International EnergyHess Corp.Marathon Oil Co.Murphy Exploration Production Co.-USANoble Energy Inc.Walter Oil Gas Corp.

Ocean Energy on the Verge of Rapid Growth?

January 6, 2011 by admin  
Filed under Ocean Energy

Is the global ocean energy industry at a turning point? With all the attention focused on energy efficiency and smart grid, and with more mature renewable sectors like wind struggling, we haven’t heard much about ocean energy in the last year or two.

Financing is tight and venture capital is extra-cautious as the world struggles to get through this tough recession. It’s not the best time for a new industry to gain footing.

High initial costs and long development lead times makes the industry dependent on government support. Ocean energy has received much less support than solar or wind, but that could change. Costs are high because prototypes must stand up to ocean storms, and in the U.S. they must navigate a confusion of overlapping offshore permitting authorities.

After only a dozen wave and tidal prototypes were installed in 2009, more than 45 projects will have been tested in 2010 and 2011, according to IHS Emerging Energy Research. If these prototypes are successful, IHS believes the global ocean energy project pipeline is poised to begin scaling. They estimate that more than 1.8 GW of ocean projects in 16 countries are currently in the pipeline.

Could Ocean Energy be Problematic for Marine Life?

But concerns are surfacing that the electro-magnetic fields created by tide and wave generators (and the cables that bring their electricity to shore) could interfere with the natural guidance systems used by marine life.

Salmon, sharks, sea turtles, lobsters and crabs are among the marine life that use internal compasses that rely on the Earth’s magnetic fields. They travel thousand of miles each year using the earth’s magnetic fields to navigate. Ocean energy machines might also produce a low hum that could interfere with communication among whales. It’s long been known that the use of military sonar poses a deadly threat to whales, many of which have been found dead or dying following massive sonic blasts.

Research hasn’t been done on how these power devices affect the marine environment.

Promise for Energy Supply

The Northwest Power Planning Council estimates ocean energy could eventually supply 10% of US energy, with 50,000 MW off the Northwest coast, equal to the output of 50 nuclear plants.

Other sites under consideration are off the coast of Maine, Hawaii, Alaska, Florida and in the Mississippi River near Baton Rouge.

Thanks to government policy support, the UK holds the lead in ocean energy - 300 MW of projects are in the pipeline to be installed over the next five years. The UK wants to add 1.3 GW by 2020 to help meet its legally binding 2020 renewable targets. Ireland, France, Portugal, South Korea and Australia are also key ocean energy markets and will remain the industry’s primary focus for the next decade, according to IHS.

And it’s not just tiny, start-ups that are pushing the field forward. A slew of established energy firms, including leading European utilities and global technology suppliers with hydro and offshore wind experience, are interested in establishing leadership positions.

Of the various forms of ocean energy, tidal energy is poised to mature first because it offers the promise of predictable, lower-cost electricity and a standard design.

“The strong synergies between tidal turbine manufacturing and the hydropower industry have attracted major power sector OEMs,” says IHS Senior Renewable Power Analyst Marianne Boust. “Over the past two years, all three of the major hydropower turbine vendors - Andritz Hydro, Alstom Hydro, and Voith Hydro - who account for over 80 percent of the global hydro turbine supply, have jumped into the tidal sector.”

Because these large hydro players see tidal energy as a synergistic growth opportunity, they are crucial to catalyzing quick development and commercialization of the tidal industry. They could help the ocean energy industry overcome its technological challenges and drive down costs.

Key companies that are active in scaling Europe’s offshore wind industry are also eyeing ocean energy as they scale their renewable portfolios. Iberdrola-ScottishPower, Vattenfall, RWE and SSE all have a strong presence in offshore wind. Each is broadening to include ocean energy. A few have taken equity stakes in ocean technology firms, but most are funding project development through joint ventures.

Ocean Power Technologies Leads

The only pure-play publicly traded company in ocean energy is Ocean Power Technologies (OPTT), which is developing the first commercial scale wave energy system in the US off the coast of Oregon. The 1.5MW wave energy system, which will power about 1000 homes, is expected to be deployed in 2011.

In September, OPTT received $4.8 million in funding from the US Department of Energy, on top of $2 million it received in 2008. They are using the funds to construct the Oregon project and to develop its next generation 500kW system, which will have greater power extraction efficiency. The company is also focused on implementing a “Design-for-Manufacture” approach and reducing maintenance costs, to achieve lower installed capital and energy costs and make wave power more competitive with fossil fuels.

Also in September, OPTT connected a wave energy device to the US grid for the first time at the US Navy’s Marine Corps Base in Hawaii. The connection demonstrates the ability of wave systems to produce utility-grade, renewable energy that can be transmitted to the grid.

The Navy has supported Ocean Power’s technology development through its $15 million Littoral Expeditionary Autonomous PowerBuoy (LEAP) program. OPTT is providing an autonomous wave energy conversion system for the Navy’s near-coast anti-terrorism and maritime surveillance program.

OPTT is also working with Mitsui Engineering Shipbuilding Co to apply its technology off the coast of Japan. In October 2009, a Japanese consortium signed a MOU to develop wave energy in Japan.

Filed under Ocean Energy

January 3, 2011

We are extremely excited about the submission of this license application, stated Ron Smith, CEO of Verdant Power. It represents the culmination of nearly a decade of work undertaken by Verdant Power and a variety of project stakeholders to add tidal power to the US clean energy mix.

Entitled the Roosevelt Island Tidal Energy (RITE) Project, the initiative has been Verdant Powers signature effort to commercialize its Free Flow kinetic hydropower system, which utilizes three-bladed turbines deployed in fast-moving tides and rivers to generate clean energy. During 2006-08, Verdant Power successfully demonstrated a Free Flow System comprised of six full-scale turbines, delivering energy to businesses in New York City with no power quality problems.

Verdant Power would install an advanced, 5th Generation Free Flow System through the proposed pilot project an updated design enhanced for system reliability, cost-effective manufacturing and environmental compatibility. The US Department of Energy (DOE) provided partial funding for this advancement, specifically the design and testing of a new composite turbine blade in partnership with the DOEs National Renewable Energy Laboratory, Sandia National Laboratories, and the University of Minnesotas St. Anthony Falls Laboratory. Major funding for the development of the RITE Project has been provided by the New York State Energy Research and Development Authority (NYSERDA) and the New York City Economic Development Corporation.

The license application has been submitted under FERCs Hydrokinetic Pilot Project Licensing Procedures, established to allow for the advancement of US hydrokinetic technologies (tidal, river, wave power), while maintaining FERC oversight and agency input. The application was prepared by Verdant Power with support from Kleinschmidt Associates and outlines the companys plans to meet FERC requirements for installation and operation, including environmental monitoring and public safeguarding. Verdant Power conducted environmental monitoring of the Free Flow System during the six-turbine demonstration at the RITE Project, developing significant environmental data on the technology that showed no evidence of increased fish injury or mortality in the demonstration area. Verdant Power would continue environmental monitoring plans, developed in conjunction with federal and state resource agencies, during the proposed pilot project to study any impacts of the larger field, which is planned for incremental installation beginning in late 2011, pending approvals.

Verdant Power

Verdant Power was established in 2000 and is headquartered in New York, NY, with international subsidiaries in Canada and the United Kingdom. Verdant Power is a world leader in the design and application of marine renewable energy systems, which utilize underwater turbines to generate clean energy from the currents of tides, rivers and manmade channels all highly predictable energy resources. Simple and modular in design, Verdant Power systems can be scaled to operate in a wide range of water settings worldwide.

Verdant Powers leadership position is demonstrated by its Roosevelt Island Tidal Energy (RITE) Project in the East River of New York City. Through this groundbreaking initiative, the Company installed and operated the worlds first array of grid-connected tidal turbines.

Zoned for wind farms: Waters south of Cape (Wind) allotted for energy projects

December 28, 2010 by admin  
Filed under Ocean Energy

Massachusetts and federal officials have designated a 3,000-square-mile swath of ocean south of Cape Cod and the Islands as available to lease to developers of commercial-scale offshore wind farms.

State officials and the U.S. Bureau of Ocean Energy Management, Regulation and Enforcement on Tuesday announced a “request for interest” to find out where in the area developers might want to pursue projects.

The area begins about 14 miles south of Martha’s Vineyard and about 24 miles south of Nantucket. It extends more than 35 miles out to sea.

It “begins a process that will lead to up to 4,000 megawatts of wind energy installed far off our shores enough electricity to power 1.7 million households and equal to the electricity currently generated by all the coal-fired plants in Massachusetts and take this new U.S. industry from infancy to maturity,” Massachusetts Energy and Environmental Affairs Secretary Ian Bowles said Tuesday.

In New Bedford, the leasing areas mean jobs and the revitalization of the city’s port, New Bedford Economic Development Council Executive Director Matthew Morrissey said. Cape Wind has fueled interest in Massachusetts as a “first mover” in the offshore wind industry, he said.

In October, Gov. Deval Patrick and Bowles announced that the port of New Bedford had been chosen as the site for a multimillion-dollar facility to support the installation of offshore wind projects including Cape Wind.

The estimated $35 million New Bedford Marine Commerce Terminal, which is planned for roughly 20 acres in the South Terminal area of the port, is expected to bring hundreds of jobs to the region and thrust New Bedford and the state to the forefront of the offshore renewable industry, according to state officials.

“There are very substantial opportunities for not just New Bedford but for other places,” Morrissey said, adding that European ports are examples of how offshore wind energy projects can help local maritime-based economies.

Bowles said information from developers and public comment will be collected ahead of a formal leasing process that will include an environmental review.

A task force that helped develop the request for interest will continue to meet and use public comments and new information to determine where leases for offshore wind are appropriate, he said.

“This is a multi-layered, ongoing, science-based review process,” he said.

But residents of Martha’s Vineyard continued to express concerns about offshore wind farms in state and federal waters, including the impact of turbines on fishing grounds and whether the projects will be visible from shore.

“Beyond that, I think that Martha’s Vineyard would like to see a community benefit if there is going to be wind development and it is going to affect the island in some way,” said Douglas Sederholm, a member of the Martha’s Vineyard Commission.

Vineyard fishermen have major concerns about the impact of turbines on navigation, said Michele Jones, secretary of the Dukes County Martha’s Vineyard Fishermen Association.

It isn’t clear whether fishermen will be allowed to work in the turbine area, she said of the possibility that insurers will require offshore wind energy developers to exclude vessels from the area.

For the Wampanoag Tribe of Gay Head (Aquinnah), the process is the immediate problem, tribal historic preservation officer Bettina Washington said.

The federal government is required to consult the tribe but has not yet done so, she said, adding that meetings of the task force do not substitute for formal consultations.

The state also announced Tuesday that it would develop a research and development program to reduce the cost of offshore wind energy.

The Massachusetts Clean Energy Center will partner with and provide matching funding to Massachusetts research institutions and offshore wind developers to win federal funding. The goal will be to reduce the cost of offshore wind 40 percent by the end of the decade and 60 percent by 2030 or to between 7 and 9 cents per kilowatt hour, according to a press release from Bowles’ office.

Tidal energy the way forward, says expert

December 25, 2010 by admin  
Filed under Secrets of the Ocean

Karachi

The creek network near Karachi has the potential to generate 8,000 megawatts (MW) of tidal energy at very cheap rates, which would be enough to end the severe power crisis the city of 18 million is facing, Dr Naseem A Khan, vice chancellor Hamdard University and former secretary Alternate Energy Board, told The News on Friday.

The Karachi Electric Supply Corporation (KESC) has an installed capacity of 1,700 MW and faces a shortfall of 500 MW, which it takes from the Water and Power Development Authority (Wapda), according to the vice chancellor.

The tidal energy generated from the creek network could become the base load and would be available for eight hours a day, he said.

Dr Khan, who has a PhD in engineering and is also an author, suggested that initially one should focus on data collection and involve local universities in that process. He said the second step must be the acquisition of the required technology, following which a feasibility report should be made.

Dr Khan believed that the project should be run by a public-private partnership. He said the project would cost $150 million and take time to become a reality, but it once does the people of Karachi would finally get rid of loadshedding.

Dr Khan said when he was secretary he made an elaborate proposal to the Alternate Energy Board. However, the government was reluctant to invest in the project despite the fact that a Turkish firm, Zorlu, was taking a keen interest in it.

He agreed that the oil lobby was so well entrenched in Pakistan that proposals for alternate energy were ignored. We have great potential for alternate energy and we also have enough human resources, but we lack initiative.

A study conducted by the National Institute of Oceanography (NIO) some 23 years ago suggested that the complex creeks network in the Indus Deltaic region, extending over an area of 170 kilometres along the 990-km coastline that Pakistan shares with the Arabian Sea, could generate 900 MW of affordable energy, which would be adequate to meet the power requirements of Karachi.

A team of scientists, led by Dr GS Quraishee, a former director general of NIO, conducted the two-year study but it was ignored by the countrys bureaucracy, apparently because the latter allegedly had a vested interest in producing energy through oil imports and enjoying huge kickbacks.

Tapping renewable energy from the ocean was becoming increasingly important, and one reason was that ocean energies were renewable and could not deplete, the study said. The other reason was that, unlike solar or wind power, which manifests itself in kilowatts, ocean energies were being debated and planned, in some cases even executed, in terms of megawatts. A third factor in its favour was the environment.

According to the NIO study entitled Feasibility studies for the extraction of energy from current and haliohydro gravity along Pakistan coast, water flows with high velocity during floods and ebb tides, which was a very favourable requirement for the extraction of energy from the currents. The bays and lagoons along Makran coast west of Karachi have narrow entrances and enclose large sea areas. The salinities in these semi-enclosed areas were higher than the open sea due to the high rate of evaporation. If the narrow entrances of these bays and lagoons were closed artificially, the evaporation will create hydraulic head with higher elevation of water level on the seaside. This head can be utilised for obtaining power. The power resources of the creeks system were great assets for future energy supply in the region. The serious power shortage which the industry was facing at Karachi can be adequately met from these resources, the study said.

Investigations carried out in all the main creeks of Indus Delta, namely Korangi Creek, Phitti Creek, Chan Waddo Creek, Khuddi Creek, Khai Creek, Paitiani Creek, Dabbo Creek, Bhuri Creek, Hajamaro Creek, Khobar Creek, Qalandri Creek, Kahr Creek, Bachiar Creek, Wari Creek and Kajhar Creek showed that, about 900MW can be produced.

In the emerging scenario when developed countries were vying to tap into environment-friendly options of tidal energy, one wonders why it was not was never considered as an option in Pakistan.
