Energy That Doesn’t Cost The Earth

​Jupiter Hydro has developed a patented tidal and river technology that we believe will prove to be the most cost effective technology in the industry. 

We are in the process of proving this by building and testing the 3EB2X10.5 turbine shown below. We plan to put this unit into a demonstration site in the Bay of Fundy.

This 5 MW demonstration site application c/w a Power Purchase Agreement (PPA) became a reality after Ross Sinclaire, Jupiter Co-CEO, and Robert Francki, Global Managing Director of Energy for Hatch Engineering, met with Keith Collins, Head of Renewables for the Nova Scotia Department of Energy. Keith saw the Jupiter advantages and encouraged us to apply for the 5 MW maximum under the newly created legislation.

Jupiter and Hatch, a 9000 employee Canadian owned international engineering firm, signed an agreement to work together in September of 2017 and Hatch loaned Jupiter money based on future equity in the company. Hatch will be engineering the units in this demonstration.

Our helical turbines have demonstrated consistent performance characteristics at high rates of efficiency under controlled testing. 

Development of the technology in tidal, river and other flows for commercial production are now an engineering and industrial design exercise, where we are utilizing innovative combinations of traditional materials, commercial off the shelf components, the latest generation of lightweight highly efficient generators and new high tech sustainable materials. 

After we test and prove the functionality of the 3EB2X10.5 300 kW turbine unit, we plan to build and deploy the same unit scaled up to produce 1 MW. This unit, the 3EB2X17.25, will have screws which are 17.5 feet in diameter with 4.5 turns whereas the 300 kW unit is 10.5 feet in diameter with 4.5 turns. The 1 MW unit can be increased to 2 MW, 3 MW and even 4 MW in a LEGO-Like fashion. 

At the 1MW unit scale we believe our costs should place our Levelised Cost of Energy (LCOE) as the lowest in the tidal industry, consistent with the company’s philosophy since its inception,

Efficient, cost effective, robust, easy to deploy and highly adaptable in- stream technology.

The Jupiter technology advantages are:

1) We are at least 2 times less costly than the publicly reported costs of our competitors.

2) The LEGO-Like modularity mentioned above is unique to the Jupiter technology and it allows for even better economies and a much smaller footprint in the ocean or river. This allows deployment in areas of high flow like no other technology. 

3) We actually have less to prove than any technology as all our components (generators, rectifiers, inverters, transformers, bearings, shock absorber mechanisms and non-ferrous rebar) are all off-the-shelf and readily available commercially.  

4) Our deployments are more environmentally friendly and our technology can handle debris better than any other technology.

5) We are far less likely to cause damage to marine life than bladed turbines because the screw allows fish to pass right on through. The Archimedes screw is currently used as fish ladders in river applications.

6) Because our pontoons are made of concrete with non-ferrous rebar (40 year lifespan) and our screw will last for 20-25 years, we are confident that we will not have to remove our turbines from the water for the length of any PPA (15 to 25)years. In case of major damage to a screw, it can be totally changed out in a few hours without the need to remove the overall unit from it’s moored location.

7) The EU is seeking to get the LOCE for tidal down to 150 Euros/MWh by 2030. We will be well below that by 2020.


The Ocean Renewable Catapult (ORE Catapult), a group of UK experts in marine renewables, found the Jupiter technology so compelling that they wrote a 30 page report under their Technology Assessment Program (TAP).

Here are a few direct quotes from that report:

1) “There is strong evidence to show that the marine energy sector has been relatively poor at identifying and focusing resources on innovations with the strongest potential”.

2) Compared with bottom fixed devices, there is growing recognition that moored, buoyant platforms offer potential advantages in power level, cost of station-keeping and ease of deployment and maintenance”.

3) The rotor enjoys the advantage of good efficiency across a broad range of tip speed ratios (TSRs). The TSRs are relatively low, about a third of horizontal axis turbines. For similar power levels, Catapult estimates that torques are roughly 50% high as a result”.

4) “The system is conceived around practicality and the TAP has no conceptual-level concerns”.

5) TAP does not consider survivability to be a major issue”.

6) “There is no reason to believe reliability is likely to be an issue”.

7) “There is a good narrative to suggest that the system could have a low Capex and Opex”.
