Reshaping Corporations: Can Divestment Work?

See on Scoop.itGreen & Sustainable News

With enough collective action, mass divestment campaigns can be effective in creating social change. 

Duane Tilden‘s insight:

>To be effective, a huge amount of money must be withdrawn from a company. Where boycotting unites individual buyers to have impact, individual stockowners aren’t likely to make a huge enough hit with divestment or negative investing for a corporation to take notice. Institutional owners, though, could impact a company or industry because collectively they control vast amounts. 

The Fossil Fuel Divestment Campaign

The current student campaign to divest from fossil fuels is interesting. For example, Harvard has $30 billion in endowment while Yale has $16.7 billion.

While it’s clearly not all in one company or industry, what kind of impact could university endowments have if they withdrew from fossil fuel companies and allied industries? By my count, there are well over a hundred campaigns at universities around the nation, and there are additional groups working to get towns and communities to join the fight. As a collective action, the potential for these divestment campaigns is fascinating to ponder.

Mass Divestment Creates Cultural Change

Perhaps the most important thing divestment shares with boycotting is publicity.  The attention that a mass divestment can bring to an issue could be profound. The student fossil fuels divestment effort is garnering national media attention, and rather than fizzling out seems to be gaining momentum. This attention could be as effective as actual divestment for dealing with climate change and fossil fuel issues. 

As Cecelie Counts wrote in January, divestment was just one tool used to combat apartheid and bring change in South Africa. I don’t know if there will be mass divestment among universities, but I suspect that this campaign will be successful in the long run because it’s educating a generation and could create the cultural change necessary to pursue long-term alternatives, change policy and pressure energy companies to adapt.<

Biofuel Production from Palm oil plantation waste

See on Scoop.itGreen Building Design – Architecture & Engineering

NextFuels to produce biofuels from palm plantation residue – Renewable Energy Magazine, at the heart of clean energy journalism

Duane Tilden‘s insight:

>Edible palm oil has surpassed soybean to become the largest source of cooking oil in the world, accounting for over 50 million tons of oil annually.

While plantation owners have managed to increase the productivity of their land by 15X since the late 80s, the growth of the industry has created a corresponding residue problem. Approximately 4.4 to 6 metric tons of agricultural waste is generated for each metric ton of oil. There are over 1,000 crude palm oil (CPO) mills in Southeast Asia and a single (60 tons per hour) mill can generate 135,000 tons of agricultural residue a year.

NextFuels uses a system called bio-liquefaction that efficiently transforms agricultural biomass to green energy. Biomass is placed into the plant mixed with water. The mixture is then heated to 330-degree Celsius while pressure is increased to 220 bar. Increasing the pressure keeps the water from coming to a boil, which conserves energy.

When cooled, the hydrocarbons form a putty-like substance called GreenCrude. Roughly 25 percent of the GreenCrude can be burned as a solid fuel in industrial boilers. The remaining 75 percent can be converted into a liquid-fuel equivalent to petroleum that is compatible with existing pipelines and vehicles.

The equipment required to convert GreenCrude into liquid fuels, in a process called hydrodeoxygenation, is already installed at most refineries and can… <

See on Scoop.itGreen Energy Technologies & Development

BOISE, IDAHO, Aug 01, 2013 (Marketwired via COMTEX) — U.S. Geothermal Inc., (nyse mkt:HTM) CA:GTH -1.96% a leading renewable energy company focused on the development, production, and sale of electricity from geothermal energy, announced () that Final Completion of the 22 megawatt (net) Neal Hot Springs Project has been achieved.

Duane Tilden‘s insight:

>The Neal Hot Springs Project was the first geothermal project to obtain a loan guarantee under the DOE’s Title XVII loan guarantee program, which was created by the Energy Policy Act of 2005 to support the deployment of innovative clean energy technologies. The DOE loan guarantee, guarantees a loan from the U.S. Treasury’s Federal Financing Bank. The project was authorized for a loan guarantee of up to $96.8 million.

The Neal Hot Springs project deployed a first of its kind binary cycle process, utilizing a supercritical cycle that uses R134a refrigerant as the working fluid, as well as pre-fabricated modular construction of major plant components. […]

The project is selling electricity to Idaho’s largest utility, Idaho Power Company, under a previously signed 25-year power purchase agreement for up to 25 megawatts of power per year. Beginning in 2012, the base energy price is $96 per MW Hour and escalates annually. The calculated 25-year levelized price is $117.65 per MW hour.<

MHI Completes Acquisition of Pratt & Whitney Power Systems

See on Scoop.itGreen Energy Technologies & Development

Tokyo, May 20, 2013 – Mitsubishi Heavy Industries, Ltd. (MHI) has completed its acquisition of Pratt & Whitney Power Systems, the small and medium-size gas turbine business unit of Pratt & Whitney (P&W), an aeroengine manufacturer.

Duane Tilden‘s insight:

>MHI has traditionally focused its gas turbine business on large-capacity, high-efficiency systems. With the addition of PWPS’s small and medium-size aero-derivative engines, MHI has expanded its power generation product portfolio and is able to offer customers a full product lineup.

PWPS’s aero-derivative gas turbines are highly acclaimed, especially for their emergency power generation applications, compact design, and rapid start-up time. More than 1,700 aero-derivative turbines have been delivered worldwide. Significant growth is anticipated in applications that require a flexible power source complementary to a renewable-energy power source. Robust market demand is also expected as small power sources for applications in emerging markets. PWPS’s main product has been the 30MW (megawatt) class machine. The company is developing an innovative 60MW class model, which is expected to significantly boost PWPS’s market share.

Turboden’s ORC turbines have the capability to generate power or supply hot water using a relatively low-temperature heat source such as biomass, factory waste heat or geothermal energy. The company has sold more than 300 units in 20 countries, primarily in Europe. In Japan, increasing opportunities are emerging to use ORC technology in biomass and geothermal applications, and MHI plans to significantly increase sales in those expanding markets.

MHI and P&W have been in a collaborative relationship in aeroengine production for many years. After the acquisition of PWPS, MHI will continue to collaborate with P&W in the supply of engine parts for gas turbines and development of new machines.<

Energy Efficiency Methods in the Cement industry – Part 1: Organic Rankine Cycle

See on Scoop.itGreen Energy Technologies & Development

Thomas B. Gibbons takes a look at the Conventional Rankine Cycle’s application in the cement sector

Duane Tilden‘s insight:

>The first major waste heat recovery (WHR) system in a cement plant was the 15 MW unit installed by Kawasaki Heavy Industries for Taiheiyo Cement in 1982. This was a conventional Rankine Cycle using heat from both the kiln and the clinker cooler. As the benefits became generally recognised within the industry, WHR units, the vast majority of which involved the conventional Rankine Cycle, were installed to provide up to about 30% of the power requirements of the plant. The main sources of waste heat were the exhaust from both the preheater and the clinker cooler and, in some of the developing countries where power outages are not unusual, the WHR system may be the only source of reliable power available to the plant operator.

Improvement in the overall efficiency of cement manufacture has resulted in lower exhaust gas temperatures and this development has provided opportunities for alternative technologies, notably the Organic Rankine Cycle (ORC) and the Kalina Cycle, which are more effective in recovering waste heat from lower temperature gases.<

Hot Rocks: Canada Sits Atop Massive Geothermal Resource – Renewable Energy

See on Scoop.itGreen & Sustainable News

September 2011 Report by the Geological Survey of Canada suggests 100 projects could provide much of the country’s power needs…

Duane Tilden‘s insight:

“Canada’s in-place geothermal power exceeds one million times Canada’s current electrical consumption,” the report notes, though also stating most of that available power could not actually be produced. “Environmental impacts of geothermal development are relatively minor compared to other energy developments, however there are still key issues to be addressed….Geothermal installations have the potential to displace other more costly and environmentally damaging technologies.”

There is at least 5000 megawatts of available geothermal power in various parts of British Columbia, Alberta, and the Yukon. What’s more, the report’s authors write, the cost of delivering geothermal power is expected to rival the costs of coal within 15 years or so. The limitations of developing the huge geothermal resource have a lot to do with location: Some of the most promising areas are far away from load centers, and the costs of developing huge transmission corridors to bring the power to where it is needed would make such projects unfeasible. Still, there is enough located in accessible areas to make a big difference.

Lockheed Martin Pioneers Ocean Thermal Energy in China – Engineers

See on Scoop.itGreen Energy Technologies & Development

A 10-megawatt ocean thermal energy conversion plant is under way

Duane Tilden‘s insight:

>[…] the company has been working on OTEC since the 1970s, and the technology hasn’t changed drastically since then. OTEC systems make use of the temperature differential in tropical areas between warm surface water and cold deep water. In most systems, ammonia, which has a very low boiling point, passes through a heat exchanger containing the warm water. The ammonia is vaporized and used to turn a turbine, and then it’s cycled past the cold water to recondense. This is a renewable energy technology with the rare capacity to supply base-load power, as water temperatures are fairly stable.

The ammonia passes through a closed loop, while the water comes and goes through massive pipes. The project in China may pump cold water up from a depth of about 1000 meters, using a pipe that’s 4 meters across. Varley says that some of the infrastructure can be borrowed from the offshore drilling industry: “We showed them our requirements for the platform, and they yawned and said, ‘Is that all you got?’ ” he says. “But then we showed them the pipe.” Attaching the massive pipe to a relatively small floating platform creates unusual stresses, Varley says. Lockheed also had to find materials for the pipes and the heat exchangers that could withstand the harsh marine environment.<

Debunking the Renewables “Disinformation Campaign”

See on Scoop.itGreen & Sustainable News

Misleading coverage fuels policy uncertainty and doubt, reducing investment security and industry development. Disinformation hurts the industry and retards its—and our nation’s—progress

Duane Tilden‘s insight:

The Fox Business example is not a singular incident. Some mainstream media around the world have a tendency to publish misinformed or, worse, systematically and falsely negative stories about renewable energy. Some of those stories’ misinformation looks innocent, due to careless reporting, sloppy fact checking, and perpetuation of old myths. But other coverage walks, or crosses, the dangerous line of a disinformation campaign—a persistent pattern of coverage meant to undermine renewables’ strong market reality. This has become common enough in mainstream media that some researchers have focused their attention on this balance of accurate and positive coverage vs. inaccurate and negative coverage.

Tim Holmes, researcher for the U.K.’s Public Interest Research Centre (PIRC), points out press coverage is important because it can influence not only “what people perceive and believe” but also “what politicians think they believe.” […]

The disinformation campaign about job creation is not limited to Europe. A Cato Institute article claimed that if people believe a commitment to renewables will fuel job growth “we’re in a lot of trouble.” Yet in 2012 alone, more than 110,000 new U.S. clean-energy direct jobs were created, and in 2010, the U.S. had more jobs in the “clean economy” than in the fossil-fuel industries. The Bureau of Labor Statistics reportsthat direct employment in May 2012 totaled 181,580 for oil and gas extraction, 87,520 for coal mining, and 93,200 for iron and steel production. BLS doesn’t similarly classify solar or wind jobs, but reputable analysts have determined from bottom-up industry surveys that in September 2012, for example, the U.S. had 119,016 direct solar jobs (89 percent full-time, the rest at least half-time), up 27 percent in two years—more than in steel-making or coal-mining. Had you heard that before? Why not?

THE COST OF DISINFORMATION

The sad truth is that the debate on clean and renewable energy is unbalanced, and seldom by accident. The CCGroup’s study showed that only 10 percent of articles focusing on renewables even contained comment from a spokesperson from the renewable energy industry. This violates basic journalistic standards. Renewables must be a part of their own conversation. Much of the conversation on renewables is misinformed and misrepresented. And when bad news does happen, says ACORE president and retired U.S. Navy Vice Admiral Dennis McGinn, opponents of renewables are pushing it “as if it’s the only news. They are dominating the conversation through misrepresentation, exaggeration, distraction, and millions of dollars in lobbying and advertising.”<

Smart Grid: Utility sued due to Smart Meter opt-out program

See on Scoop.itGreen Energy Technologies & Development

Smart Grid – BC Hydro offered customers who didn’t want to participate in its smart meter program the choice of opting out in mid-July. But that didn’t protect the utility from a lawsuit

Duane Tilden‘s insight:

>Just days after BC Hydro finally agreed to an opt-out program for smart meters, a customer is suing the utility for installing a smart meter last year even though she didn’t want one on her property. […]

The suit claims the installations caused the plaintiff “emotional distress,” because it “interfered with the quiet enjoyment of her property,” which she used to host yoga and meditation retreats. Opponents of smart meters believe the devices’ radio waves have health risks. The lawsuit further alleges that BC Hydro unlawfully leveraged its monopoly powers by imposing a smart meter on the plaintiff.

[…] The utility says that smart meters only broadcast several times a day, and that living next to a smart meter for 20 years would expose a resident to the same level of radiation as a 30-minute cell phone call.<
