On the path to clean energy

The Southeastern Massachusetts region is positioning itself as a serious player in the growing clean energy industry, working to build an active supply chain for clean energy developments, even as the industry itself struggles to build momentum.

A recent clean energy study put Massachusetts third overall in the country in terms of clean energy development and, while the state’s southeast region may not be the driving force for that ranking, it also doesn’t plan to be left out.

“Conversations have begun with companies not just in the offshore renewable space, but in solar or whatever,” said Matthew Morrissey, executive director of the New Bedford Economic Development Center. “New Bedford is on the map as a player in a space that a lot of companies want to be in right now.”

While Morrissey and other city and regional officials are working to have multiple renewable energy resources represented, the biggest success to date has been in offshore wind energy with the city’s selection as a staging area for Cape Wind.

In fact, much of the anticipated regional growth hinges on the fortunes of the country’s first fully permitted offshore wind farm, a project that has faced numerous hurdles, but may still get in the water in 2012.

Although facing litigation and without financing, Cape Wind spokesman Mark Rodgers said the 130-turbine project expects to begin installation next year. At a June 16 Council on Sustainability meeting in Fall River, Rodgers didn’t seemed concerned about litigation, calling efforts “the last play of our opposition;” but, said securing financing has been difficult.

“(Financing) is a major challeng-It’s going to take some time and effort,” he said.

Rodgers said the New Bedford staging area, a $35-million port facility to be built on the city’s waterfront, needs to be ready in time for Cape Wind installation.

That won’t be a problem, according to Morrissey, who said the project is in the engineering stage and ground is expected to be broken this fall.

“That project is moving forward,” said Morrissey. “We’re much more concerned with Cape Wind’s need to finalize their program…The remaining 50 percent of power has to be worked out as well as financing.”

The port facility, on New Bedford’s active waterfront, will do more than just help the city get its foot in the clean energy door, it will also let the city leverage its working port, boosting its import and export trade business, according to Harbor Development Commission director, Kristen Decas.

Decas said the city is also tracking other offshore wind developments along with tidal energy keeping an eye on how the port can play a role in supporting development.

“We’re a sleeping giant and we have huge room for using this asset,” said Decas, about the harbor. “This facility will put us on the map for a variety of future opportunities in offshore energy development.”

Middleboro manufacturer, Mass Tank, will also benefit from offshore wind project, shifting its past expertise building steel tanks for the oil industry into building monopoles for wind turbines. Mass Tank, through its ECO Fab partnership, will build a new manufacturing plant, to supply steel structures to Cape Wind and other offshore wind developments. The plant is expected to employ at least 300 people.

Although the specific location of the facility is unknown, reports have suggested both Quincy and New Bedford are in the running.

According to Morrissey, opportunities for Mass Tank still exist in New Bedford but the decision will depend on whether or not the city can provide a site that meets Mass Tanks’ specific needs.

“They’ve been very clear all along, they would like to be in New Bedford,” Morrissey said in mid-June. “They’re from here; they’d like to be here and it is less expensive to do business here. The question is that the characteristics of the site that is required for the activity are not immediately available.”

While other industries continue to grow in the state, including solar which increased 20-fold between 2007 and 2010 according to Mass CEC, Massachusetts’ clean energy future may depend on offshore wind, according to some experts.

Offshore wind may be the state’s best resource or at least the best one that is technologically ready for implementation, according to Ron Pernick, co-founder and managing director of Clean Edge, an Oregon-based clean-tech research firm.

Pernick said Massachusetts is at a geographic disadvantage when it comes to producing renewable energy, compared to other states that have heavy wind or lots of sun.

“Massachusetts doesn’t have the wind resources on land like these other places,” said Pernick, citing states like Iowa and North Dakota, which are producing 15.4 percent and 12 percent of their electricity through wind respectively.

In Clean Edge’s leadership index, released in May, Massachusetts got high marks in categories like policy, venture and human capital, and clean energy patents, but still scored in the lower half of the country when it comes to energy production.

The state placed third overall, below California and Oregon.

The production category represents technical deployment including how much wind power, solar, biofuels, geothermal and other energy sources are in use, as well as the number of electric vehicles on the road, according to Pernick.

Still, Pernick, said, the Cape Wind project has the potential to change everything for the state.

“If you bring the Cape Wind project online, if you develop offshore wind and tidal energy, you’ll see yourself move up,” he said, referring to the state’s positioning.

And, while offshore wind is new to the state, it isn’t a new technology. There are more than 40 offshore wind farms off the European coast, according to Rodgers.

That’s different from ocean energy which is a relatively untested technology, Pernick said.

“I think, over time, wave and tidal energy offer significant promise, but I think it’s further out than a five year timeline,” he said.

At the Marine Renewable Energy Center in New Bedford, director John R. Miller believes ocean energy, including offshore wind, is the state’s alternative energy future.

“I always tell people that solar energy and biofuel are two things that are of great interest to venture capital people in Boston€but if you think of somebody who wants to build a big solar energy plant, they’re more likely to do it in Arizona or Spain where there’s a lot more sunshine,” said Miller. “If you look at what resource we actually have — the ocean is a resource that is literally on our doorstep.”

Miller said ongoing efforts to develop new ocean technologies, even if they are not created here in Massachusetts, will still need to be built and maintained locally. So it’s important that the region begin taking steps to develop a workforce and build a supply chain for the industry, he said.

Some of that is already happening through the Southeast Development Partnership, out of UMass Dartmouth, Miller said.

“They’re looking at all the pieces in the supply chain,” said Miller. “(Questions like,) what do we have now, what are we going to need in five years, and how can we convince the company who is manufacturing cables, for example, to locate in the Southcoast?”

While offshore wind may be the state’s bright future, it is also one of the most controversial forms of renewable energy, along with land-based wind, according to David McGlinchey, of the Manoment Center for Conservation Sciences.

As senior program leader for energy, McGlinchey said he participates in many conversations about wind energy and development projects. He wants to lessen the controversy by helping projects strike a balance between energy benefits and environmental and quality-of-life impacts.

“The challenges from my perspective are not technical, they’re social,” said McGlinchey. “There are real benefits (to wind projects), but they also have an impact. The key is balancing that, finding appropriate sites that balance benefits and impacts.”

McGlinchey said the Manoment center is putting together a guide, to be released in September, to help municipalities create bylaws based on the science behind wind and their own local values.

“It will give them the tools they can use to build an effective bylaw,” he said.

Despite frequent wind opposition, McGlinchey said he believes people are becoming more supportive of renewable energy ventures.

“I feel very confident that (issues) can be worked out. I think we’re getting better at it,” he said. “The vast majority of people in these conversations inherently want to find solutions. The key is having a reasonable, informed conversation which is not easy.”

Rodgers too said public opinion has shifted in the last few years. Despite a slightly battle-weary tone, he spoke very positively about clean energy technology and its potential impact on the region.

“A sustainability cluster is starting to take shape,” he said. “We have the makings to be one of those clean energy global hot spots.”

Plumbing the oceans could bring limitless clean energy

For a company whose business is rocket science Lockheed Martin has been paying unusual attention to plumbing of late. The aerospace giant has kept its engineers occupied for the past 12 months poring over designs for what amounts to a very long fibreglass pipe.

It is, of course, no ordinary pipe but an integral part of the technology behind Ocean Thermal Energy Conversion (OTEC), a clean, renewable energy source that has the potential to free many economies from their dependence on oil.

“This has the potential to become the biggest source of renewable energy in the world,” says Robert Cohen, who headed the US federal ocean thermal energy programme in the early 1970s.

As the price of fossil fuels soars, private companies from Hawaii to Japan are racing to build commercial OTEC plants. The trick is to exploit the difference in temperature between seawater near the surface and deep down (see diagram).

First, warm surface water heats a fluid with a low boiling point, such as ammonia or a mixture of ammonia and water. When this “working fluid” boils, the resulting gas creates enough pressure to drive a turbine that generates power. The gas is then cooled by passing it through cold water pumped up from the ocean depths via massive fibreglass tubes, perhaps 1000 metres long and 27 metres in diameter, that suck up cold water at a rate of 1000 tonnes per second. While the gas condenses back into a liquid that can be used again, the water is returned to the deep ocean. “It’s just like a conventional power plant where you burn a fuel like coal to create steam,” says Cohen.
