The World's first OTEC system that's affordable on a small scale.

Traditional Ocean thermal energy conversion (OTEC) is proven to work, it’s just renewable organic Rankine cycle.

Traditional OTEC could have been made to work 100 years ago, in fact most if not all the parts can come from well-known public companies.

Traditional OTEC is expensive so it is not competitively priced on small or even large scales, furthermore, larger scale projects have feasibility problems.

New-otec means a new cold-water delivery system, and a new lower cost.

Now the promise of 24-7 clean power throughout the tropics and beyond can become a reality.

Constant clean power with a low space requirement.

OTEC power generation is organic Rankine cycle with a low, but naturally occurring temperature difference.

Now that we have a low-cost cold-water delivery system, we do not need to scale up to be cost effective.

That means a reasonably sized plant that is also a reasonable investment.

Lower costs mean that sites further away from the cold-water source, 10 km or more, are now feasibly in range.

Do you have space problems which make the use of solar PV difficult?

OTEC uses larger than normal heat exchangers, but the space required is still 1000 times less than Solar PV.

Most if not all the parts can come from well-known public companies!

THE USE OF HOSES AND A TURBO-PUMP CAN LOWER THE COST OF OTEC.

HOSES CAN BE INSTALLED IN 1-DAY by a small team.

HOSES CAN BE RETRIEVED JUST AS EASILY AND SO MAINTENANCE IS STRAIGHTFORWARD AND RELATIVELY LOW COST.

There is economy of scale with a greater power requirement and this economy is far more easily achieved with hoses than with pipes.

Additional economy can be found with additional heat from any suitable source.

Additional heat can significantly increase the power output of a plant for a given hose and heat exchanger size, as well as its year round capability.

Additional heat can lower the plant cost per kw dramatically.

WHAT AM I BUYING...?

A shell and tube heat-exchanger system.

A turbo-generator.

Other power electronics and telematics systems for motor control, and remote monitoring.

Working fluid pumps.

At least one pair of hoses, and mender couplings.

At least one turbo-pump.

Sea water sumps, filters, and pumps.

Miscellaneous including gauges and sensors.

 

Optional extras include:

Multi-stack motors.

(Seasonal temperature changes mean that you could double your power output in the summer with the same heat exchanger and water delivery system.)

Additional Heat exchangers.

Additional heat exchangers will provide more net power, and a prolonged heat exchanger service life.

For areas closer to the edge of the tropics where there are greater seasonal temperature differences, more heat exchangers will grant year-round ‘base-load’ power, and the opportunity to double power output in the summer.

Additional waste heat or renewable heat, heat exchangers.

Additional heat and an additional heat exchanger can change the cost of OTEC by 50% or more.  This step would be recommended in all but the very best natural sites and even then, it would still be worth doing.  It all depends on how much extra heat there is as to how much more power you can produce.

An installation service.

(Hose and HX Installation might be simple enough for some organisations to be able to do it themselves.)

Groundworks.

An operation and maintenance service.

 A battery bank.

Low-cost Hose protectors.

A bespoke site-specific shore-side hose-protection system.

(Where hoses are being hit by waves and are travelling over uneven, rocky ground or a steep ledge.)
