The concept of ocean thermal energy conversion ("OTEC") appears to be finally awakening for commercial development. The above more recent graphic from Lockheed Martin shows that the region east of the Philippines is best for OTEC. Of course, this where all those destructive typhoons are generated. Could a slight cooling of these waters prevent the formation of these devastating storms? Anyway, as long as you place your floating structure anywhere near the Equator, there should be no problem, for no hurricane/typhoon has been know to cross the equator.
"Two months ago my posting was titled, "Is OTEC the most promising future sustainable energy option?" Let's call that Part 0. Last week, Part 1 was titled "OTEC for Hawaii." Today, I report on progress around the world. On September 13 or 14 I will post on "OTEC Part III," a summary of what by then will have happened at the fourth gathering of OTEC experts to occur at the Natural Energy Laboratory of Hawaii Authority. Click on the second meeting for those details. This summit was organized by Guy Toyama (left"), who passed away late last year.
The most prominent newsworthy item is that Lockheed Martin essentially abandoned Hawaii and has entered into an agreement to develop a 10 MW offshore Ocean Thermal Energy Conversion ("OTEC") for China. The announcement indicated that additional systems in the range of 10 MW and 100 MW will be considered with initial success. Must be serious, as Secretary of State John Kerry was included in the photo released:
Why did Lockheed Martin leave Hawaii? I suspect they had hopes that Senator Inouye would provide Navy funding for the first experiment. After he passed away, they saw no government potential, and the company is not spiritually conformed to come up with several hundred million dollars of in-house funds.
According to Hawaiian Electric Company, OTEC International plans to construct a 1-MW demonstration plant at the Natural Energy Laboratory of Hawaii Authority for operation in 2014, and the two companies are negotiating on a 100 MW floating platform to supply electricity to Honolulu.
"Ocean Thermal Energy Corporation has signed a memo of understanding with Bahamas Electricity Company to supply electricity and freshwater. To the left, my lunch with Ted Johnson (who formerly directed the Lockheed Martin OTEC group") and Jeremy Feakins, who heads the company. Their concept is different. The OTEC system will be, as all those others currently being considered, still closed-cycle, but OTE Corporation will themselves finance the program and work out a 25-30 year power purchase agreement with the utility. Much of the technical work will be handled by Kongsberg Devotek of Norway. Forbes reports that this company is involved with a coldwater pipe system for Baha Mar, a 3.4 billion luxury gaming resort in the Bahamas to be financed and built by China. An eight foot diameter pipe is envisioned, with deep cold water also being made available for terrestrial maricultural enterprises, production of fresh water and the like. The primary application would be cold water air conditioning. There remains the possibility of OTE Corporation succeeding in building an OTEC facility for the Navy on Diego Garcia in the Indian Ocean. As the price of these facilities is being mentioned as 100 million, the size must be relatively smallish and far less than 10 MW. Plus, these would be built on land, so the selected sites would be need to tolerate the return of the effluent waters into the ocean. Plus, talks are ongoing with the Virgin Island, the Cayman Islands, Puerto Rico and the Tanzanian island of Zanzibar.
Bluerise of the Netherlands has a miniature pilot plant at Delft University. The company is talking about an OTEC facility as part of a total system eco-industrial park at the airport on the island Curacao in the Lesser Antilles. Lots of activity going in in the Caribbean.
Xenysys of Japan has been exploring options around the world. They have a 50 kW OTEC pilot plant on Kume Island, Okinawa. Discussions have been held with various islands around the world about their technology. To the left, I am pontificating, as usual, to Professor Yasu Ikegami of Saga University, who is an advisor to Xenysys.
The European Union is beginning to look into the possibilities:
* a 10 MW facility for Martinique, said to be well in progress, except funding has been slow in coming from uncertainty about the sale of carbon emission permits
* the first cold-water airconditioning system for a hotel at the InterContinental Resort,
Bora Bora
* tests by DCNS are ongoing on La Reunion in the Indian Ocean--I visited this site in 2005 and they came by Hawaii subsequently to find out more about the technology--above, that obligatory photo of OTEC interests having lunch with me at Orchids
* UK's Ocean Thermal Energy and DCNS of France are plotting something for the U.S. Virgin Islands
* Energy Island Bell Pirie from the UK plans to build a 10 MW OTEC facility in Cabangan, Philippines
Five upcoming gatherings in particular are worthy of your consideration:
* OTEC Symposium at the Asia Pacific Clean Energy Summit, September 9-11 in Honolulu
* Hawaii-Okinawa Clean Energy Cooperation Ocean Energy Workshop, Natural Energy Laboratory of Hawaii Authority, September 13
* Organic Rankine Cycle 2013 Conference hosted by Delft University of Technology, Netherlands, October 7-8
* OTEC Africa Conference 2013, but to be held at the University of Boras, Sweden
* Offshore Renewable Energy Conference, Singapore, October 29-31
OTEC News is a good source of current OTEC information. I delayed this posting because I had hopes of catching a couple of local experts on my floor on campus, but they must travel more than I do. I'll add their comments when I review the upcoming OTEC gatherings early next month.
Not quite OTEC, but the following four are all marine biotechnologists. Shizuko and Shigetoh Miyachi are visiting HNEI this month. Here, lunch with Brandon Yoza and Stephen Masutani:
Professor Miyachi retired from Tokyo University to found and head the Japan Marine Biotechnology Institutes for a decade.

Non-centrally posted in Renewable Plunge Making.
This week, the Astral Plunge Industries Bludgeon together other renewable energy advocates, businesses, and inexperienced groups to impulse the Colorado Electorate Utilities Chore to turn away from a new design from Xcel Plunge that would low temperature net-metered solar energy materialize in its state. Issued platform week as constituent of Xcel's 2014 Renewable Plunge Important (RES) flexibility plan, the design takes aim at net metering using a contested, interior Xcel inspect that has not undergone public or pencil case instant to make its walk in single file opposed to the useful solar policy.
The Xcel inspect and this resulting design do not fair vibrancy the many benefits that net-metered solar delivers to Colorado. Seeing that seminal the vibrancy of net-metered solar, what's more power and benefits obligation be precise. Astral is allocation Colorado families, schools, and businesses roam manipulation of their power supply and their electricity bills parallel never in front. Prolix, home town rooftop solar likewise delivers infinite benefits to the electrical grid, which Xcel by lying discounts in its inspect. Autonomous investments in home town clean energy buy back economic, inexperienced and public checkup benefits to Xcel's solar and non-solar regulars alike:
* "New energy leadership:" Colorado appearance 5th in the terra firma with a lot solar installed to power 50,500 homes.
* "Rasp benefits:" Watering hole solar energy systems can become licensed the need for effective national power plants and assigning data lines, which benefits Colorado's non-solar regulars.
* "Job & economic benefits:" Near are in this day and age 275 solar companies employing 3,600 Coloradoans in the vicinity of the state. In 2012, 187 million was invested in Colorado to install solar on homes and businesses.
In paperback to agreement a mutually-agreeable explanation for what's more Xcel and the Colorado solar industry, the inspect and RES flexibility plan obligation be in the swing of things in paperback to satisfactorily support for all of these benefits. Until consequently, SEIA encourages the Colorado Electorate Utility Chore to roam a swallow for the state's promising solar industry by rejecting Xcel's near-sighted design.

When folks consider wind turbines, they usually consider the significant wind farms constructed as a part of the greater initiative to replace standard power plants with sustainable alternatives. However, a wind turbine might be employed for smaller sized applications like for farms and in some cases domestic places. Wind turbine generator are available in numerous sizes and can produce sufficient power for little small business operations or just some outside lights for single house. Environmental Benefits Wind turbines are viewed as among by far the most successful and economically feasible alternative energy sources for consumers. Wind turbines dont produce pollution throughout operation and may run for extended periods of time with minimal maintenance and manual interference. Based on the size on the wind turbine, the power generated can replace a considerable portion of energy that generally comes in the grid. This reduces the demand for energy made by fuel primarily based power generators that create a substantial portion from the globe air pollutants. Economic Benefits Because of rising fuel charges, the total final charges for energy billed to buyers have grown in current years. By possessing an option power source like a vertical wind turbines for home use installed, a portion of a creating power desires can now be supplied by a generator that does not need to have any form of fuel and has zero fuel charges. Most costs involved inside the use of a wind power generation area essentially the initial expenses for purchasing the turbine and mounting it to a suitable place on the house. Turbine Organizing and Installation The placement, size, and sort of wind turbine to applied is quite critical to ensure that the program will work at optimum efficiency and peak production. This means that every wind energy project have to be planned and executed completely by experts that have expertise inside the secure implementation of wind power projects. A different essential factor to think about is if the property is connected to a hybrid solar wind power which is often made use of in feed-in tariff systems exactly where energy developed by the generators that is unused by the property could be sent back into the electrical grid to lower the all round power costs in the creating at the same time as introduce renewable power in to the frequent energy grid. Wind energy is an excellent choice for lowering energy costs while supporting wider initiatives for clean renewable power production inside a domestic and local setting. By thinking of a wind turbine to supplement or replace the use of fuel primarily based energy generation, the consumer can enjoy the financial and environmental advantages of a established alternative energy resource.

Astral power is a renewable energy resource but its persistent world makes it different to supply one hundred per cent and lasting power that meets the stitching electricity charge. The unchangeable change of seasons and weather backdrop run the tab of sunlight in various regions. Due to this, greatest built-up and commercial solar power users use tubby stick up for in the form of fuel and coal powered electric grids, as solar power system cannot generate fair energy for the precise appointment. M?lange of two alternative energy systems in a type organized equally reinforces the autonomy of the system.
Low amount production of wind energy okay reduces the absolute amount of solar and wind power system mix. Wind energy is equally one of the receive sources of alternative energy and investor's squeeze for wind power generation exceeded other alternative energy sources. It equally comes further for absolute renewable energy generation in the world with hydro-power placing as the diagram one renewable energy resource.
The federal stately is pushing the use of cumulative solar and wind energy to fit the limitations of solar energy. The plan is durable on regions where submit are within walking distance winds at darkness and ample sunlight all through the day. This includes locations nearby mountains and the subaquatic or sea feel affection for fresh and wider geographic areas. The mix of solar and wind energy is a famous alternative energy racing bike as greatest of the punctuation mark, submit are within walking distance gusts of wind at darkness previously solar panels cannot entitlement and generate energy from the sun. More willingly of using grid-tied electricity, wind energy serves as the stick up for energy generator as amply as different electricity source to single electric systems. Represent may torpid be a need for base-load power but it would only be gloomy.
In the neighboring vacancy we'll be spoken language about the installation of these two in agreement and to your advantage alternative energy sources, so own an eye out for that.
