Ocean thermal energy conversion gets one step closer to commercial reality

otecUPDATE: An interesting announcement from Lockheed Martin this morning. The military contractor says it has signed a “memorandum agreement” with real-estate developer Reignwood Group, founded and run by Thai-Chinese businessman Yan Bin, the second-richest man in Beijing. What have they agreed to do? Lockheed says it will design a 10-megawatt ocean thermal energy conversion (OTEC) plant, which will supply 100 per cent of the power needs of a planned “net-zero” green resort being built by Reignwood. “The agreement could lay the foundation for the development of several additional OTEC power plants ranging in size from 10 to 100 megawatts, for a potential multi-billion dollar value,” according to Lockheed in a press release.

This is exciting for two reasons. One, it’s very cool technology, and being an energy geek I love hearing this kind of news. Two, there’s huge potential here for the ocean to supply emission-free electricity around the world. Lockheed has been working on this technology since the 1970s. An OTEC power plant basically uses heat exchangers to extract heat out of the warmer upper ocean layers and create steam from a working fluid with a low boiling temperature, such as ammonia. As I wrote in my book Mad Like Tesla, “The steam would drive a turbine that generates electricity. Cold water from deeper layers would then be used to condense the ammonia back into fluid, at which point the cycle would be repeated.” In my book, I quoted Ted Johnson, director of alternative energy development at Lockheed, who is clearly optimistic about what the technology could offer. “I dream of thousands of floating OTEC ships roaming the seas of the world, providing an inexhaustible supply of clean energy and fuel and water for all people of the world.”

While Lockheed has been working on this for four decades, one of the first in-depth discussions of the concept came from Nikola Tesla, who at the age of 75 outlined how such a plant might be built in the December 1931 issue of Everyday Science and Mechanics journal. Tesla spent considerable time trying devising a way to improve the efficiencies of such a power plant, but he determined that it was too great an engineering challenge at the time. “I have studied this plan of power production from all angles and have devised apparatus for bringing down all losses to what I might call the irreducible minimum and still I find the performance too small to enable successful competition with the present methods,” he wrote, though still expressing hope that new methods would eventually make it possible to economically tap the thermal energy in oceans.

Lockheed is trying to demonstrate that the day has come. “Constructing a sea-based, multi-megawatt pilot OTEC power plant for Reignwood Group is the final step in making it an economic option to meet growing needs for clean, reliable energy,” said Dan Heller, vice-president of new ventures for Lockheed’s mission systems and training group. Lockheed said the technology is “well-suited” to island and coastal communities where — because of transportation logistics — energy prices tend to be high and there is great dependency on oil for power generation. “Unlike other renewable energy technologies, this power is also base load, meaning it can be produced consistently 24 hours a day, 365 days a year,” said Lockheed. “A commercial-scale OTEC plant will have the capability to power a small city. The energy can also be used for the cultivation of other crucial resources such as clean drinking water and hydrogen for applications such as electric vehicles.”

Continues Lockheed: “Once the proposed plant is developed and operational, the two companies plan to use the knowledge gained to improve the design of the additional commercial-scale plants, to be built over the next 10 years. Each 100-megawatt OTEC facility could produce the same amount of energy in a year as 1.3 million barrels of oil, decrease carbon emissions by half a million tons and provide a domestic energy source that is sustainable, reliable and secure. With oil trading near $100 a barrel, the fuel-savings from one plant could top $130 million per year.”

There is one point of confusion, however. Lockheed says this planned OTEC project — at 10 megawatts — will be the largest ever built, but I was under the impression it had designed or was in the process of designing a 10MW plant off the coast of Hawaii. I’ve e-mailed Lockheed asking for clarification on this and will update my post when I get an answer. For more background on this concept check out this story from a few months back by the folks at Greentech Media.

(UPDATE: I received a response from Lockheed spokesman Scott Lusk on the company’s work in Hawaii. Here’s what he had to say: “While Hawaii is one of the main places where Lockheed Martin has conducted research and evaluation around the OTEC technology, to date there have been no contracts awarded for commercial-scale OTEC development in the state. Lockheed Martin has tested the heat exchanger technology, a critical component in the OTEC plant design, at the NELHA research facility in Hawaii. In addition, Hawaii is one of several locations where Lockheed Martin has conducted feasibility studies. Other locations include Guam and Japan.”)

Clean Break column in Toronto Star ends a 10-year run…

photoIt was a trip to Iceland in June 2003, just months after the birth of my first daughter, that the immense need for and potential of clean energy first landed on my radar. The Toronto Star agreed to send me there so I could write about Iceland’s efforts to transition to a hydrogen economy. I toured several of the country’s geothermal and hydroelectric facilities. I rode on hydrogen fuel cell buses. I swam in the Blue Lagoon. I spoke with some of the leading academics and engineers in the world working on the hydrogen puzzle. I came back inspired, hungry to learn more — not just about fuel cells and hydrogen, but about this whole emerging area of clean technology, or “cleantech.” It helped that Canadian fuel cell pioneers Ballard Power and Hydrogenics had already captured my interest, but once I looked beyond the “hype about hydrogen” I saw a great diversity of clean technologies at various stages of development. Further boosting my enthusiasm was Nick Parker, founder of the Cleantech Group and the man who coined the term “cleantech.” It was about that time that I first met Nick at a venture capital conference in Toronto. I had covered the technology and telecom scene for five years and was getting bored. The market had tanked. No longer was it interesting to write about faster routers and fatter broadband services. I was more drawn to the optical engineers who left telecom behind and decided to use their skills to boost the potential of solar PV technology and LEDs. Nick and the handful of companies he brought to the venture capital conference only had a small piece of the floor, but they were the most fascinating to cover. I was hooked.

Within just a couple of months after my trip to Iceland, I decided to transition my weekly high-tech column at the Toronto Star into a clean technology column. It began as a bi-weekly effort, but by the following year my transition was complete — Clean Break was a weekly column devoted to cleantech, and a first of its kind in North American for a major daily newspaper. This blog soon followed, one of the first cleantech blogs to hit the blogosphere. Parker’s Cleantech Group recognized this in 2005 by selecting me for the Cleantech Pioneer award. What Nick liked about the Clean Break column is that it was in the business section of the newspaper, which conveyed the idea that most of the technologies I was writing about weren’t destined to be money-losing propositions but were either competitive today or had the potential to be competitive; that tackling climate and other environmental issues through efficiency and using carbon-free technologies was a way to boost productivity and global competitiveness. Readers also liked the emphasis on solutions, as opposed to dwelling on environmental problems. I didn’t see myself as an environmental reporter, at least not of the traditional sort — that is, only investigating and exposing bad apples, and only telling readers how much things sucked. That was just too depressing. I liked highlighting innovation that was going to help get us out of the environmental mess we had created, and even better, help boost revenues and lower costs for companies and governments. I wanted to put less emphasis on environmental compliance (a pure cost) and more emphasis on the embrace of “clean” technologies because it was simply good for business. I thank the Toronto Star for letting me go in this direction, or at least not preventing me from doing so.

Much has changed in the 10 years that have followed. That whole hydrogen thing didn’t turn out as planned. Plug-in vehicles, hardly talked about a decade ago, have taken over and remarkably all of the top auto manufacturers now have pure electric or hybrid-electric models on the market. Sales haven’t been a strong as predicted, but the fact there are tens of thousands of plug-in vehicles on the roads and thousands of high-speed charging stations installed is a dramatic accomplishment in my view. Same goes for solar and wind technologies. Less than 600 megawatts of solar capacity were installed in 2003. That figure has surpassed 30,000 megawatts, meaning the market has grown 50-fold over the past decade, and we’ll see another 10-fold expansion by 2020. Currently there are about 96,000 megawatts of total solar capacity installed worldwide, a figure that’s expected to reach 330,000 megawatts in seven years. In other words, since starting my Clean Break column solar has gone mainstream — a combination of plunging prices and progressive government policies. The wind industry, which had an installed capacity of about 39,000 megawatts in 2003, has grown to have a total capacity that now stands at 283,000 megawatts. These are huge numbers. Last year, an astonishing $269 billion was invested in clean energy infrastructure. In 2010, investments in renewable energy exceeded investments in fossil fuelled power plants for the first time, a major global milestone. Venture capital in cleantech, depending on how you define it, jumped from about $1 billion to over $8 billion from 2005 to 2011 (it’s now around $6 billion). The market for cleantech is, generally speaking, a trillion-dollar global opportunity.

Media coverage of the industry — new and traditional — has also changed. In 2005 my blog was among a handful of blogs consistently covering the cleantech space, and my column was unique in North American, at least for a mainstream daily newspaper. Now, as I wrote in my book Mad Like Tesla, “I am but one small voice in a sea of dedicated news sites, columns, blogs, Facebook pages, and Twitterers all covering different angles of this clean energy revolution and advocating for a faster transition away from fossil fuels. We may complain that the transition is going too slowly — it can never move fast enough — but looking back it’s amazing we have come this far so quickly.” As coverage of the sector increased, my own writings became increasingly regional and local. Most of my Clean Break columns for the past few years have focused on my home province of Ontario or home city of Toronto. I’ve most enjoyed writing about Canadian or Ontario-based clean technology startups or innovators trying to raise the bar on efficiency and lower environmental footprints. My columns have covered LEDs, solar power, wind power, demand-response, green chemistry, smart grid innovation, water technologies, geothermal, biofuels (with a big focus on algae), electric vehicles, carbon capture and storage, nuclear, wave and tidal power, biogas, waste reduction, energy storage, advanced materials… you name it. I have learned so much, met so many wonderful and smart people, made new friends and played my own little part in helping Canadian companies get attention locally and globally. It has been tremendously satisfying.

Why am I writing all of this now? Well, because this July would have been the 10-year anniversary for my Clean Break column in the Toronto Star. Also, just before I went to Costa Rica earlier this month for vacation, I got a call telling me that my column had been cancelled. I can’t say it was entirely unexpected. When I left my full-time staff writing gig at the Star in 2010 to write Mad Like Tesla, the paper’s business editor at the time agreed on a handshake to let me keep writing the column. Three editors have come and gone from the business section since then and during each transition the axe was expected to come. It didn’t, and frankly, I’m amazed I made it this far. It’s been a great run. The fact is, the newspaper industry is going through a painful transition and there’s no indication this is temporary. In fact, the pain indicates something that may be terminal. The Star recently announced it was outsourcing its pagination and copy editing functions to save costs and that 55 jobs would be cut. Sections across the paper have been asked to slash budgets, and the axe falls easily on freelance columns. This is an unfortunate sign of the times. That my column was discontinued is also a sign of the times. Clean energy may be the future and climate change is the biggest threat to our existence, but that didn’t stop the New York Times from recently dismantling its own environmental reporting team and cancelling its popular green blog. This is both the knee-jerk reaction of an industry that’s suffering, and the reason why this industry is suffering — in my humble opinion.

To be fair to the Star, it did recently hire a global environmental reporter and global science and technology reporter. This is great news. Change is good, and people will get fresh coverage and viewpoints. Let’s hope they stay committed to these beats and give the stories that come out of them the priority and placement they deserve. Me, I’m having a blast as editor of Corporate Knights magazine, where I have been for nearly two years, and I hope to spend the next few years building this publication. We’re doing great things and insightful research — not just in cleantech, but around a number of issues where business and sustainability intersect. I encourage all my readers to sign up for Corporate Knights’ digital subscription, which you can get through iTunes by downloading our app in the App Store (We’re also available on Kindle through Amazon.com, and soon coming to the Android marketplace). Besides, I needed a break from the column and had been considering new directions for it for some time. Its Canada/Ontario/Toronto focus was appropriate for a paper like the Toronto Star, but I want to broaden the message and the audience. Over the coming months I will be looking at a national or North American media platform through which to revive the column, in partnership likely with Corporate Knights. In the meantime, I’ll continue to use this blog to highlight new technologies, emerging issues, breaking news, and whatever else tickles my fancy. The Clean Break brand is here to stay.

Finally, if you were a regular reader of my Clean Break column in the Star, thank you very much for tuning in. Many hundreds, possibly thousands, have reached out to me over the years to convey their appreciation or dislike of the column — fortunately it’s been more of the former. Sometimes people just wanted to exchange ideas. I can’t tell you how heart-warming it is to get an e-mail from a teacher who’s using my column as material for the classroom, or a call from a student who wants to interview me for a class project, or getting Tim Horton’s gift certificates in the mail from an anonymous person thanking me for doing what I’m doing, or getting a call from the founder of a startup who got venture capital funding because of an article I wrote, or having a politician tell me that my coverage of an issue had an impact on policy or legislation. Without readers — even the ones who call you an idiot, and there have been many — there’s no point in writing.

Unfortunately, the Toronto Star would not allow me to do a final farewell column to notify my readers that this is the end of the line, for now. Some of you might have noticed it was no longer being published. But most won’t notice, and I expect this will hold true for many of my colleagues still word-tapping at the Star. Columns come and go, and mine is no different. It would have been nice, however, to thank my Star readers more directly, rather than through the more limited audience that this blog attracts.

Will Alberta clean energy “firsts” add up to more in 2013? Here’s hoping…

If Alberta was a book, it wouldn’t be fair to judge Canada’s third-largest economy only by its oil-soaked cover.

Sure, the oil and gas sectors are the largest contributors to Alberta’s economy. Yes, documents recently obtained by Greenpeace reveal a far too cosy relationship between the provincial government and industry, if pipeline safety reviews are any indication.

But beyond the ruling Conservative government and the dominance of the petroleum sector are a growing number of progressive Albertan municipalities and entrepreneurs working toward a future not entirely dependent on fossil fuels.

Many achievements, in fact, mark firsts for Canada. The Town of Okotoks, a 15-minute drive from Calgary, was the first community to heat an entire neighbourhood with a solar district heating system. Calgary’s light-rail transit system, the CTrain, is the first to get all of its electricity from wind power.

This year, Edmonton became the first municipality to produce ethanol at a commercial scale from its municipal solid waste.

Meanwhile, a Calgary-based company called Borealis GeoPower aims to generate geothermal power from the hot wastewater that emerges as a byproduct of oil and gas production in the northern Alberta town of Swan Hills – another first, potentially.

One project this writer is eagerly following is developing in Medicine Hat, a municipality often referred to as “Gas City” because of the discovery in 1883 of major natural gas reserves.

Medicine Hat is attempting to prove that, even in a cold northern place like Alberta, energy from the sun can be harnessed directly at existing thermal power plants to displace the use of fossil fuels.

This isn’t a new idea. It’s been talked about since 2007, when the city commissioned a feasibility study to determine if it could be done and made good sense.

Medicine Hat is, in fact, the best place in this massive country to put up solar panels. The city gets more sunlight over a year than any other Canadian city – nearly 50 per cent more sunshine than Toronto.

Would you believe even more than Miami?

Medicine Hat’s plan is to install solar collectors (a type known as parabolic troughs) that can concentrate sunlight so much that the heat produced can turn water into steam. That steam will be fed into the steam generators at the municipality’s existing 203-megawatt thermal power plant, which normally relies on natural gas to produce steam.

Once completed, likely before next fall, it will be the first concentrated solar power (CSP) project built in Canada, as well as the first one ever integrated directly into a natural gas plant.

In October, the city selected Colorado-based SkyFuel to supply eight of its solar collector assemblies for the project, which will be capable of offsetting the equivalent of 1.1 megawatts of electricity normally generated from natural gas.

It’s not much, given the size of the plant, but as a demonstration project it will answer all sorts of questions. Can it scale up? Where else in Alberta would this approach be used? Could it work at coal-fired power plants and in the oil sands to offset natural gas used in bitumen extraction?

How economical is it, both today and as technology improves and costs fall? Who knows, maybe it will prove more cost-effective than carbon capture and storage (CCS) technologies as a way to comply with federal environmental regulations, which will start to kick in come 2015?

One can only hope that the many “firsts” that Alberta is achieving in the area of clean energy will begin to add up and gather collective momentum, and at the same time get the province’s energy-dependent economy on the path to diversification.

Solar. Geothermal. Energy from waste. Wind. All of it will be needed to reduce Alberta’s dependence on fossil fuels, which currently represent more than 90 per cent of its power generation.

The province’s municipalities and entrepreneurs are leading the way, and they deserve the support and encouragement of all Canadians if we are to tackle climate change as a country.

Lady Gaga tweets are not enough… movie/rock stars should unite for climate awareness, action

Back in the mid-1980s dozens of high-profile music artists from the United Kingdom, United States and Canada got together in their respective countries to raise awareness and stimulate discussion of famine in Ethiopia.

Bono, David Bowie and Sting helped lead Band Aid, the U.K. supergroup that created the song Do They Know It’s Christmas? This was followed by USA for Africa’s We Are The World, which included Michael Jackson, Bruce Springsteen and Bob Dylan.

Canada’s contribution was Northern Lights’ Tears Are Not Enough, featuring heavyweights Bryan Adams, Neil Young, Anne Murray and Geddy Lee.

In all, the three songs resulted in the sale of more than 35 million copies worldwide and shined a bright light on an issue that had received little attention by the mainstream media, politicians and the general public.

I couldn’t help but recall the impact of these songs, and the phenomenon of celebrity influence, while listening earlier this week to Stanford University professor Mark Jacobson, who spoke at an event at the University of Toronto co-hosted by several community groups, including the Citizen’s Climate Lobby and Post Carbon Toronto.

I’ll make the link between star power and Jacobson later in this column, but first some background on the good professor.

Jacobson is a bit of a rock star himself in academic circles, at least when it comes to another problem that’s putting millions – potentially billions – of lives at risk. He has spent his career trying to understand the global impacts of air pollution and climate change, as well as how to quickly and responsibly transition from our dependence on fossil fuels to a world powered by renewable energy.

“Air pollution alone kills 2.5 to 3 million people at least a year worldwide,” he told those gathered to attend his Toronto lecture. He then rattled off a list of other problems associated with fossil fuels—rising global temperature and sea level, record Arctic ice loss, more frequent extreme weather events, and volatile energy prices, to name a few.

“These are drastic problems that require drastic solutions, and we think they need to be addressed immediately. We can’t wait 20 or 30 years, which is why we’ve really got to focus on technologies that exist today, that can be implemented for the most part right away, and that can be implemented at large scale.”

Jacobson caught people’s attention three years ago with his co-authored article A Plan To Power 100 Percent of the Planet With Renewables, which was the cover story for a 2009 issue of Scientific American.

Many roll their eyes at the suggestion that renewables can do it all for us, but one by one Jacobson’s article dispelled many myths about green power and convincingly argued that wind, water and sun could do the heavy lifting if we had the collective will power to make it happen.

It analyzed the impacts of each type of “clean” energy source independently, including land and water footprint, the materials required to make it, how much pollution would be created during its full lifecycle, and overall contribution to global warming.

Wind turbines, various forms of solar technology, hydropower and geothermal plants, and to a lesser extent wave and tidal energy, got top marks. Nuclear, coal with carbon capture and storage, natural gas and biomass didn’t make the cut.

In the area of transportation, he favoured electric or hydrogen-powered vehicles over those that used compressed natural gas or biofuels such as ethanol.

“Why not natural gas?” he said last week. “Because it releases at least 50 to 70 times more carbon and air pollution than wind energy per kilowatt-hour generated… It’s a bridge fuel to nowhere.”

Jacobson has calculated that a world where all industry and transportation is powered by renewables would require installation of 3.8 million wind turbines, 1.7 billion residential and commercial rooftop solar systems, about 90,000 solar plants each 300 megawatts in size, 5,350 geothermal plants 100 megawatts in size, and about 1.5 million wave and tidal devices.

It seems like a lot, but it’s all relative. Consider the estimated 20 to 30 million abandoned oil and gas wells worldwide, or the many millions of smokestacks that dot our city and urban landscapes. Considers that the planet is wrapped in a mesh of more than two million kilometres of pipeline infrastructure, enough to stretch to the moon and back nearly three times.

His renewables plan, he pointed out, would take up less than 1 per cent of land space on the planet.

Now comes the star power. Jacobson has teamed up with the greenest, most powerful ally one could imagine: the Incredible Hulk. Well, actually actor Mark Ruffalo, who played the Hulk in The Avengers movie.

They’re leading an initiative called The Solutions Project, which is trying to bring together high profile scientists, business people, investors, movie makers and Hollywood stars in an effort to drive home the message that 100-per cent renewable energy is not only doable, but should be done.

Their first effort, to be announced shortly, will be to develop a comprehensive green plan for New York State, followed by other states and eventually other countries.

Actors Leonardo DiCaprio and Scarlett Johansson are lending their star power to the cause, along with documentary movie director Josh Fox, celebrity entrepreneur Elon Musk, and philanthropist Eileen Rockefeller.

Jacobson and Ruffalo, who co-authored an article for Huffington Post that appeared in June, said their goal is to “inspire millions to take part in an energy revolution.”

“Today, with social media and the reach of pop culture, we can educate people and achieve what was unthinkable five years ago,” they wrote. “It is up to us to grab hold of our potential and change our world for the better.”

Individual tweets from Lady Gaga and Justin Bieber are not going to change things. Having celebrities join forces with scientists and policymakers against a global threat like climate change, as they did for African famine in the mid-80s, just might.

For this reason, Jacobson is on the right track.

As Ontario moves to remove barriers to municipal PACE financing, Toronto prepares to embrace it

Tyler Hamilton
 Homeowners in Ontario could soon finance efficiency retrofits and solar panel installations through an additional charge on their property taxes, but only if the province makes good on regulatory changes it proposed last month.

The amendments, which affect the Municipal Act and City of Toronto Act, have to do with a financing tool used by municipalities called “local improvement charges.”

If a sewer pipe is replaced, a sidewalk laid or a road repaved a town or city can spread part of the cost among affected property owners through a special charge added to their property tax bill.

To date, such charges have been limited by law to neighbourhood improvement projects. But Toronto councillor Mike Layton said the proposed changes would allow municipalities to enter into agreements with individual property owners wishing to, for example, invest in changes to their home that would reduce energy or water consumption.

“Your property itself can qualify for a local improvement charge,” said Layton, who is eager to see pilot projects launched in Toronto that would take advantage of this new municipal tool. “We’ve got to prove to people that this works.”

It’s an important development, given that the McGuinty government seems to have dropped the ball on its conservation efforts. As Gord Miller, Ontario’s environmental commissioner, recently pointed out in an annual report, “the conservation promises of the Green Energy Act remain unfulfilled” and “some commitments appear to have been quietly abandoned.”

Empowering municipalities may be one of the best ways to make up for lost time. The regulatory changes mean municipalities would be able to leverage their ability to raise cheap capital through bond issues, and then offer homeowners low-interest financing that can be paid back over 10 or 15 years through property taxes.

If designed correctly, the energy or water savings that result will more than offset the monthly or annual payments. In the case of solar, revenues from clean electricity sold to the province under the feed-in-tariff program would more than cover the local improvement charge.

An added bonus is that the local improvement charge is tied to the home, not the homeowner, so it doesn’t add to your personal debt load.

One of the key champions of this model has been Sonja Persram, president of Sustainable Alternatives Consulting Inc. in Toronto (I wrote about her efforts last November).

Persram has studied the approach closely over the past three years, working with groups such as the David Suzuki Foundation to build support among business leaders, labour groups and particularly Ontario municipalities.

“There’s been a huge amount of interest from a broad spectrum of municipalities, at all levels,” said Persram, adding that she’s pleased to see the province taking action.

Another big fan is Bill Johnston, former president of the Toronto Real Estate Board and current director with the Canadian Real Estate Association.

“The program imposes no costs upon any level of government. In fact, it may provide a small return at the municipal level,” he said. “It will create employment, generating extra tax dollars at the provincial and federal levels. Furthermore, by improving indoor air quality, health care costs will be reduced.”

Layton, anticipating that the amendments will be passed, sent a letter earlier this month to the city’s Economic Development Committee asking that it get the city manager to develop a pilot program and conduct an economic analysis in time for the committee’s October meeting.

He envisions the program being tested in four Toronto districts, starting with a focus on energy efficiency retrofits and potentially expanding to water conservation and green energy projects, including solar and geothermal.

“We’d basically pick a handful of communities where there’s interest, and give it a try,” said Layton.

The challenge between now and then is to demonstrate to the rest of council that such a program wouldn’t come at a cost to the city. The benefits, however, are that it would contribute to environmental objectives and create economic activity and jobs for the city and surrounding region.

Another plus is that, by spurring energy and water conservation, pressure it taken off of city infrastructure. In other words, more efficient use of existing infrastructure will defer the big cost of future upgrades and expansions.

“Once you present all the evidence, and maybe I’m naïve here, but I would think the majority of members of the executive committee would say it’s foolish to not approve this kind of strategy,” Layton said.

This all assumes, of course, that the province follows through.
