Changing of the Tides – How One Alberta Company Is Driving Hydrokinetic Power

Published

8 minute read

The energy conversation has been a polarized debate for years and continues to hit headlines. The clean energy industry is driven by forward-thinking individuals who have one common goal, transitioning from traditional energy sources to a more sustainable form of energy. Now in 2020, we have more oil than we know what to do with, an unprecedented amount of unused facilities that require cleanup, and jobs being lost daily. We exist in a time where competition drives innovation, demonstrating proof of concept is essential to drive investment and still, unable to see eye to eye for a common approach. Let me ask you this, is it problematic for us as a society to hold onto previous conceptions of clean energy projects, regardless of what type? 

Jupiter Hydro was founded in September 2010 by Co-CEO Ross Sinclaire in Calgary, Alberta. Their main focus is in-stream hydrokinetic power generation. Co-Ceo Bob Knight joined the team later in their development. If you have read into hydropower in the past, you may be aware of this type of power generation. Jupiter Hydro has taken the benefits of traditional hydropower and combined their unique technology to produce a far more cost-effective and sustainable form of hydrokinetic power generation. 

Like any new technology that works to produce power in a non-traditional method, Jupiter Hydro has gone through three phases over a decade that has brought them a unique opportunity in Nova Scotia’s Bay of Fundy scheduled for later in 2020. Beginning with testing their hypothesis, proving the theory of generating rotational power utilizing an Archimedes screw presented to fluid flow at an angle was tested in an irrigation channel. With promise in their theory, they move to test their methodology developed to quantify produced power was developed using a rudimentary test tank and 3D printed screws. Mounting systems were developed and fabrications were created with cost-effective materials. In 2012, testing at the University of Calgary’s test tank began to quantify torque characteristics and confirmed blade pitch and presentation characteristics. Both the horizontal orientation and longitudinal orientation of the screw were tested, giving insight into a highly effective angle for their Archimedes screw.

Open Water Testing

Crucial for any proof of concept in hydrokinetic power generation, Jupiter Hydro began their open water testing in 2013 in the Fraser River in BC. Early tests allowed discrepancies to be addressed with submerged generators and confirmed scalability for the technology for the team. Their second open water test addressed the longitudinal placement of their Archimedes screw while testing a swing arm in open water. With support from the Canadian Hydrokinetic Turbine Test Center, they had their third and fourth test at the facility to demonstrate the technology to identify flow clearances for their swing arm. They recorded nearly 50% efficiency and formed the basis of their current design for the upcoming Bay of Fundy project.

 

Defining In-Stream Hydrokinetics

In-stream hydrokinetics can be defined as harnessing the natural flow of water to provide rotational power. “In-stream” means that no containment or diversions are required, meaning that obstruction of the water flow is not required; be it a river, dam outflow, canal, or tidal flow. No dams or penstocks are required, and water flow is not restricted. If we consider that there are over 8500 named rivers in Canada according to the WWF, with the addition of ocean currents or any source of flowing water, the resources are huge for this technology. 

Key Innovation

If we visit the pros and cons that have been put on traditional hydro, we tend to lie on the outstanding cons that have given the industry a black eye over the last decade. As mentioned previously, competition drives innovation, to which Jupiter Hydro has adapted previous technology with a new methodology to produce a new in-stream power generation. Through multiple test phases and focusing on being cost-effective, they have created patented technology to produce power utilizing the 2,000 year old Archimedes screw with a pitch of 60% of the diameter and angled at 30 degrees to the flow to produce high torque power from the in-stream flow. Traditionally, hydropower would require a permanent infrastructure and there is a risk for large scale remediation. Jupiter Hydro does not require any permanent infrastructure and thus they do not require any remediation from environmental disturbance. 

Environmental Impact

With the majority of power generating technologies, lowering the environmental impact can be one of the prominent challenges even for clean energy. If we address the main environmental concerns with hydropower, it consists of concerns of remediation of land, impacts on fish, sourcing of materials, and noise pollution. Jupiter Hydro has effectively addressed these concerns with mitigating the risk for potential investors and the societal impact of driving clean energy into the future. They have the ability to provide remote sites with dependable power without the need for extensive shore infrastructure or changes to the channel flow. The technology can provide clean power in areas historically powered by diesel generators or bio-mass. Their system in rivers can provide “base line” dispatchable power, one of the key requirements for a 100% renewable energy system. 

Bay of Fundy Project

On July 3, 2019 Jupiter Hydro Inc. was granted a 2 MW demonstration permit and Power Purchase Agreement (PPA) in the Bay of Fundy by the Nova Scotia Government. This area has seen other tidal power companies like Cape Sharp Tidal and Minas Tidal and have attempted to crack into the Bay of Fundy’s 2,500-megawatt potential. The terms for Jupiter Hydro is for three sets of 5 years, totaling a 15-year project to be launched later in the year. In the image below you can see their in-stream hydrokinetic tidal platform that will be used in the 2 MW project.

Due to issues relating to the ongoing pandemic, the date of this project remains currently unknown. We look forward to future updates from Jupiter Hydro and their success in the Bay of Fundy. Nova Scotia hit a milestone last year for reaching 30% of its energy produced by renewable sources. They continue to be a key driver for this industry.

Canada’s economy has stagnated despite Ottawa’s spin

Published on

From the Fraser Institute

By Ben Eisen, Milagros Palacios and Lawrence Schembri

Canada’s inflation-adjusted per-person annual economic growth rate (0.7 per cent) is meaningfully worse than the G7 average (1.0 per cent) over this same period. The gap with the U.S. (1.2 per cent) is even larger. Only Italy performed worse than Canada.

Growth in gross domestic product (GDP), the total value of all goods and services produced in the economy annually, is one of the most frequently cited indicators of Canada’s economic performance. Journalists, politicians and analysts often compare various measures of Canada’s total GDP growth to other countries, or to Canada’s past performance, to assess the health of the economy and living standards. However, this statistic is misleading as a measure of living standards when population growth rates vary greatly across countries or over time.

Federal Finance Minister Chrystia Freeland, for example, recently boasted that Canada had experienced the “strongest economic growth in the G7” in 2022. Although the Trudeau government often uses international comparisons on aggregate GDP growth as evidence of economic success, it’s not the first to do so. In 2015, then-prime minister Stephen Harper said Canada’s GDP growth was “head and shoulders above all our G7 partners over the long term.”

Unfortunately, such statements do more to obscure public understanding of Canada’s economic performance than enlighten it. In reality, aggregate GDP growth statistics are not driven by productivity improvements and do not reflect rising living standards. Instead, they’re primarily the result of differences in population and labour force growth. In other words, they aren’t primarily the result of Canadians becoming better at producing goods and services (i.e. productivity) and thus generating more income for their families. Instead, they primarily reflect the fact that there are simply more people working, which increases the total amount of goods and services produced but doesn’t necessarily translate into increased living standards.

Let’s look at the numbers. Canada’s annual average GDP growth (with no adjustment for population) from 2000 to 2023 was the second-highest in the G7 at 1.8 per cent, just behind the United States at 1.9 per cent. That sounds good, until you make a simple adjustment for population changes by comparing GDP per person. Then a completely different story emerges.

Canada’s inflation-adjusted per-person annual economic growth rate (0.7 per cent) is meaningfully worse than the G7 average (1.0 per cent) over this same period. The gap with the U.S. (1.2 per cent) is even larger. Only Italy performed worse than Canada.

Why the inversion of results from good to bad? Because Canada has had by far the fastest population growth rate in the G7, growing at an annualized rate of 1.1 per cent—more than twice the annual population growth rate of the G7 as a whole at 0.5 per cent. In aggregate, Canada’s population increased by 29.8 per cent during this time period compared to just 11.5 per cent in the entire G7.

Clearly, aggregate GDP growth is a poor tool for international comparisons. It’s also not a good way to assess changes in Canada’s performance over time because Canada’s rate of population growth has not been constant. Starting in 2016, sharply higher rates of immigration have led to a pronounced increase in population growth. This increase has effectively partially obscured historically weak economic growth per person over the same period.

Specifically, from 2015 to 2023, under the Trudeau government, inflation-adjusted per-person economic growth averaged just 0.3 per cent. For historical perspective, per-person economic growth was 0.8 per cent annually under Brian Mulroney, 2.4 per cent under Jean Chrétien and 2.0 per cent under Paul Martin.

Due to Canada’s sharp increase in population growth in recent years, aggregate GDP growth is a misleading indicator for comparing economic growth performance across countries or time periods. Canada is not leading the G7, or doing well in historical terms, when it comes to economic growth measures that make simple adjustments for our rapidly growing population. In reality, we’ve become a growth laggard and our living standards have largely stagnated for the better part of a decade.

Powerful players count on corruption of ideal carbon tax

Published on

From the Fraser Institute

By Kenneth P. Green

Prime Minister Trudeau recently whipped out the big guns of rhetoric and said the premiers of Alberta, Nova Scotia, New Brunswick, Newfoundland and Labrador, Ontario, Prince Edward Island and Saskatchewan are “misleading” Canadians and “not telling the truth” about the carbon tax. Also recently, a group of economists circulated a one-sided open letter extolling the virtues of carbon pricing.

Not to be left out, a few of us at the Fraser Institute recently debated whether the carbon tax should or could be reformed. Ross McKitrick and Elmira Aliakbari argued that while the existing carbon tax regime is badly marred by numerous greenhouse gas (GHG) regulations and mandates, is incompletely revenue-neutral, lacks uniformity across the economy and society, is set at an arbitrary price and so on, it remains repairable. “Of all the options,” they write, “it is widely acknowledged that a carbon tax allows the most flexibility and cost-effectiveness in the pursuit of society’s climate goals. The federal government has an opportunity to fix the shortcomings of its carbon tax plan and mitigate some of its associated economic costs.”

I argued, by contrast, that due to various incentives, Canada’s relevant decision-makers (politicians, regulators and big business) would all resist any reforms to the carbon tax that might bring it into the “ideal form” taught in schools of economics. To these groups, corruption of the “ideal carbon tax” is not a bug, it’s a feature.

Thus, governments face the constant allure of diverting tax revenues to favour one constituency over another. In the case of the carbon tax, Quebec is the big winner here. Atlantic Canada was also recently won by having its home heating oil exempted from carbon pricing (while out in the frosty plains, those using natural gas heating will feel the tax’s pinch).

Regulators, well, they live or die by the maintenance and growth of regulation. And when it comes to climate change, as McKitrick recently observed in a separate commentary, we’re not talking about only a few regulations. Canada has “clean fuel regulations, the oil-and-gas-sector emissions cap, the electricity sector coal phase-out, strict energy efficiency rules for new and existing buildings, new performance mandates for natural gas-fired generation plants, the regulatory blockade against liquified natural gas export facilities” and many more. All of these, he noted, are “boulders” blocking the implementation of an ideal carbon tax.

Finally, big business (such as Stellantis-LG, Volkswagen, Ford, Northvolt and others), which have been the recipients of subsidies for GHG-reducing activities, don’t want to see the driver of those subsidies (GHG regulations) repealed. And that’s only in the electric vehicle space. Governments also heavily subsidize wind and solar power businesses who get a 30 per cent investment tax credit though 2034. They also don’t want to see the underlying regulatory structures that justify the tax credit go away.

Clearly, all governments that tax GHG emissions divert some or all of the revenues raised into their general budgets, and none have removed regulations (or even reduced the rate of regulation) after implementing carbon-pricing. Yet many economists cling to the idea that carbon taxes are either fine as they are or can be reformed with modest tweaks. This is the great carbon-pricing will o’ the wisp, leading Canadian climate policy into a perilous swamp.
