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

Traditional OTEC is proven to work, but it’s expensive; 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.

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.

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.

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.

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

WHAT AM I BUYING...?

A 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.

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 be worth doing.  It all depends on how much heat there is as to how much more power you can produce.  The advantage to using cold water and warm surface water first is that the heat required for the working fluid phase change is renewable, so the additional heat can mostly be net power not rejected heat.  In other words, 100 kw of waste heat would provide perhaps 75 kw of net power, and this is not normally possible.  The use of extra heat also eradicates the problem of a low-pressure differential in the turbo-generator system adding complete certainty to operational capability.  Sites not normally suitable for OTEC can be with extra heat.  You can visit the research page for more or get in touch via the contact page.

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.

(We aim to have a complete service system in operation across the World.)

 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.)
