Big Hydro’s Big Days are behind us
The $6.5-billion Romaine ” big hydro” development in Quebec, Canada will produce 1,550 MW: $4200/kW. British Columbia’s plan to build a new $8.8-billion hydro project on the Peace River for 1,100-megawatt: $8,000/kW. Manitoba may be in the worst shape of all: it has green-lighted the $6.5-billion, 700-megawatt Keeyask dam: $9286/kW (9 cents per kilowatt-hour).
There are additional indirect costs: damming interrupts the flow of rivers and can harm local ecosystems, and building large dams and reservoirs often involves displacing people and wildlife.
Cheap and abundant U.S. natural gas, with its lighter (than coal) carbon footprint, is eating Canadian hydro’s lunch. Export prices averaged 6.5 cents per kw/h in 2008. By 2012, that was down to 3.1 cents per kw/h – far below the production costs of any new hydro projects being built now.
Comparisons of life-cycle greenhouse gas emissions or global warming, which uses the global warming potential unit, the Carbon dioxide equivalent(CO2e)/kWh: 400 for natural gas and 700 to 1000 (without scrubbing) for coal.
Climate change is the most difficult problem the world has ever faced: it is huge in its global scope and they are the biggest challenge of the century. We have far more oil, coal and gas than we can safely burn. We can only avoid devastating damage if most of the world’s coal, oil and gas are left in the ground. We can’t burn them if we care about climate change.
Here is the problem: even if we gave up on all the obscure and unconventional fossil fuel resources that companies are spending billions trying to access and just burned the “proven” oil, coal and gas reserves – the ones that are already economically viable – we would emit almost 3 tons of carbon dioxide. No one can say exactly how much warming that would cause, but it is overwhelmingly likely that we would shoot well past 2 C degree and towards 3 C degree or even 4 C degree of warming.
The Burning Question
The book, Burning Question reveals climate change to be the most fascinating scientific, political and social puzzle in history. It shows that carbon emissions are still accelerating upwards, following an exponential curve that goes back centuries.
The simple truth is that tackling global warming will mean persuading the world to abandon oil, coal and gas. For all the uncertainty about the detail, every science academy in the world accepts the mainstream view of man-made global warming.
Electricity has to be the Dominant Energy Form
Worldwide energy usage is on track to increase by roughly 40% in the next 20 years and to nearly double by 2050. Carbon emissions still have to be cut 84% by 2050, yet almost 70% of the kilowatt-hours of electricity consumed today comes from coal or natural gas.. Electricity has to be the dominant energy form used in the future.
While solar energy might yield 150 watts per square meter on a sunny midday and wind power could produce 300 watts during a similar time period, wave energy has the potential to create 30,000 watts per square meter: it’s very power dense.
The wave energy industry is in its infancy, with no commercial-scale facilities operating anywhere in the world. Wave power experts say that wave energy is where wind energy was three decades ago. While other forms of alternative energy like solar, wind and biomass see hundreds of billions of dollars in investment each year, wave energy does not see even $1 billion in investment.
The allure is irresistible. A wave energy machine that could harness an inexhaustible, nonpolluting source of energy and be deployed economically in sufficient numbers to generate significant amounts of electricity—that would be a feat for the ages.
Electricity: the Great Enabler of Modern Society
The fact is, we are at an inflection point. The decisions we make today — or fail to make — regarding our electricity system will have repercussions for generations to come.
In Canada, electricity assets are reaching the end of their lifecycle, which can range from 30 years for a utility pole to as much as a century for a power plant. Much of the system built a generation ago now needs to be replaced or refurbished and when it comes to renewing electricity infrastructure, the lead times are long – often measured in decades.
Over the past decade, utilities have made investments of about $9 to $11 billion per year. However, according to the Conference Board, just to keep the system running will require some $350 billion over the next 20 years, which translates to about $15 billion per year.
But looking ahead, new technologies like small hydro will have an enormous impact on the electricity industry.
Enter: the HUG Wave Energy
Compare this with a Hydo electric farm based on wave energy, an energy source, which has been elusive for the last 40 years. Wave Energy technologies would be 100 times more effective at fighting climate change than fossil fuel power plants on a per-kWh basis because it has Zero g of carbon dioxide produced per kWh.
Enter the base power HUG: $.02 /kWh ($0.01/kWh carbon credits): 11 MW cost 10.5 Million: ($10,500,000/11,000 kW = $954/kW )
HUG Wave Energy will be lower-cost, lower-maintenance, and longer-lived than any of the other wave-energy devices, of which we are currently aware. The HUG‘s compact and robust wave power plant enables over ten times higher annual energy output per ton compared to conventional wave devices.
Furthermore, because HUG Wave Energy can operate in the deep sea, and not just onshore or near-shore like so many of the other systems being developed or deployed today, farms of HUG devices will not damage or displace sensitive coastal ecosystems, won’t interfere with local shipping; it will be able to scale virtually without limit, providing as much power as is needed.
Considering the ability of HUG devices to generate power in waves too small to energize many other devices, our analyses of historical wave data (obtained from NOAA buoys monitoring the wave climate) show that farms of HUG devices would have capacity factors more than high enough to allow them to serve as baseload power sources (unlike wind, solar, and many other wave energy devices).
Floating Turbine System
Now you can anchor a cable to either side of a stream/river and have floating turbines turned by the ordinary current. A floating HUG Helical Turbine System will capture the kinetic energy from the current. No dam required, just a flow. It wouldn’t bother the fish. It would interfere with navigation if they were anchored only halfway across, leaving half the river open to navigation. Thousands of small rivers and streams could possibly be utilized this way.
The Pump HUG is used in a river current to increases its velocity between two to four times because of the vortex inside.
The game changer will be the introduction of the innovative HUG, which will both provide electricity in rural remote areas. What is more important: HUG will provide electricity using fast moving water for an irrigation system, extending to 25 km from any slow moving water source. This will increase the productivity of our supported farms by 300%, because there will be three to four harvests per year.
