Lockheed Martin Pioneers Ocean Thermal Energy in China – Engineers

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.<

Industrial Energy Management – Contolling Demand & Energy Usage

See on Scoop.itGreen Energy Technologies & Development

Demand-control technology supports multiple approaches for taming energy costs without sacrificing production efficiency.

Duane Tilden‘s insight:

>Navigant Research argues that efficient energy management will soon be as important as product quality in determining manufacturers’ competitive position within their respective industries. That importance, according to Navigant, is reflected in the compound annual growth rate for industrial energy management software and services.

At its current growth rate, the global market for industrial energy management solutions will nearly double over the next 7 years, going from $11.3 billion in 2013 to $22.4 billion in 2020… <

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.”<

Creating Value: Energy Retrofits for Buildings

See on Scoop.itGreen & Sustainable News

Buildings in the U.S. consume[…] 42 percent of the nation’s primary energy and 72 percent of its electricity. Much of that energy is needlessly wasted through inefficient design and operation.

Duane Tilden‘s insight:

>Rather than examine energy costs in isolation, our approach assesses how energy and sustainability improvements add value to all parts of a property or company. This approach is not revolutionary, but rather more comprehensive, applying industry-accepted valuation methods to the full set of retrofit value contributions, including saved energy costs, health and productivity benefits, reputation and leadership, and risk reduction.

Energy investment (and resultant property outcomes) should be treated as one of many factors that influence value, including location, tenant mix, quality of design, and more. Evaluating retrofits within the broader context of property/company value enables a logical, defensible calculation and assessment of a deep retrofit’s relative contribution to value. Previous attempts to value energy retrofits have ignored retrofits’ value contributions and overlooked standard approaches to valuing properties and companies.<

Jobs for the Future: Energy Efficiency creates Employment — ECEEE

See on Scoop.itGreen & Sustainable News

Energy efficiency initiatives create jobs, and normally very good jobs.  Recent analysis shows that between 17 and 19 net jobs can be created for every million euros spent.

Duane Tilden‘s insight:

>Jobs to improve energy efficiency in all end-use sectors are of high value.  Many require technical qualifications, such as engineering or architectural degrees.  Many require re-training from existing jobs. There will be a demand for financial specialists, construction engineers, behaviour specialists, project managers, auditors, data base managers, policy analysts and the like.  And these jobs are available to all, regardless of age or gender.

The hard work of creating these jobs begins once the Directive is finally approved.  The long-term policy framework needs to be in place and the funding and implementation strategy need to be well developed. But in the longer term, opportunity is knocking at the door, and it deserves a welcome mat.<

Bakken Oil: North Dakota flaring burns 4 times Total National Consumption (2011 figure)

See on Scoop.itGreen & Sustainable News

NEW YORK (Reuters) – Oil drillers in North Dakota’s Bakken shale fields are allowing nearly a third of the natural gas they drill to burn off into the air, with a value of more than $100 million per month,…

Duane Tilden‘s insight:

An alarming state of affairs.  As per the article the flared Natural gas in North Dakota is reported to be 266,000,000,000 cfd (cubic feet per day) flared methane or 2750 x 10(9) cu m/year.

According to Wiki the 2011 US annual consumption for natural gas was 689.9 x 10(9) cu m, so apparently Bakken is actually burning 4 times the total 2011 national requirements.

>Roughly 29 percent of natural gas extracted in North Dakota was flared in May, down from an all-time high of 36 percent in September 2011. But the volume of natural gas produced has nearly tripled in that timeframe to about 900,000 million cubic feet per day, boosting flaring in the state to roughly 266,000 million cubic feet per day, according to North Dakota state and Ceres data.<

UK Shopping Centre goes zero Waste to landfill in a year

See on Scoop.itGreen & Sustainable News

As a new member of the National Recycling Star scheme, Clifton Down Shopping Centre received the Gold award for its recycling and waste management efforts and in recognition of its success in diverting all of its waste from landfill.

Duane Tilden‘s insight:

>The transformation in the centre’s waste management began with a full site audit to identify areas of poor practise within both its waste management and energy efficiency operations.  […]

As the shopping centre began to look at improving its waste management plan, it asked its tenants to start flat packing their waste cardboard, so it can be sent to the centre’s onsite compactor. Pre-flat packing waste cardboard has allowed the centre to double the amount of cardboard that can be collected by its waste contractor Smiths, while saving space in the services yard. This has cut the number of collections required, helping to save fuel consumption and CO2 emissions. All general waste produced by the shopping centre is sent to New Earth Solution’s mechanical biological treatment (MBT) facility at Avonmouth.

Clifton Down Shopping Centre has also been working to reduce its environmental impact by tackling its energy efficiency. New LED light fittings have been installed throughout the shopping centre, significantly reducing energy consumption and cost. The centre previously used old halogen lighting which consumed 14,994kW per annum, compared with the replacement LED lighting which consumes 2,998kW – an 80 per cent reduction. […]

The centre has also installed seasonal sensitive automatic doors at both entrances. These are programmed to close more quickly during winter months to minimise heat lose. This is switched during summer with doors remaining open for longer, allowing for cooler air to circulate the building. New electricity, water and gas monitors have been installed throughout the centre to measure consumption and identify areas of potential savings.<

China’s Coal-Fired Economy Dying of Thirst as Mines Lack Water

See on Scoop.itGreen & Sustainable News

Coal industries and power stations use as much as 17 percent of China’s water, and almost all of the collieries are in the vast energy basin in the north that is also one of the country’s driest regions.

Duane Tilden‘s insight:

>About half of China’s rivers have dried up since 1990 and those that remain are mostly contaminated. Without enough water, coal can’t be mined, new power stations can’t run and the economy can’t grow. At least 80 percent of the nation’s coal comes from regions where the United Nations says water supplies are either “stressed” or in “absolute scarcity.” […]

Geneva-based Pictet Asset Management’s $3.17 billion global water fund doubled its exposure to stocks offering water services in China to 10 percent since 2007.  […]

Beijing Enterprises has risen 55 percent this year to HK$3.10 and Deutsche Bank sees it reaching HK$3.20 within a year. China Everbright is up 81 percent to HK$7.10 and JPMorgan Chase & Co. estimates it will reach HK$7.60 by mid-October.

Severe Pollution  “The best opportunity is in industrial water re-use, and for the mining industry, it is of the utmost urgency,” said Junwei Hafner-Cai, a manager of RobecoSAM’s Sustainable Water fund. “Water that has been released from the coal mines and from petrochemical plants has resulted in severe pollution on top of the water scarcity.”

A shortage of coal because of the lack of water to mine and process the fuel may force China to increase imports, pushing up world prices, according to Debra Tan, director at research firm China Water Risk in Hong Kong. China, which mines 45 percent of the world’s coal, may adopt an aggressive “coal-mine grab” to secure supplies, said Tan.<

It’s Time Our Policies Reflect The Fact That Energy And Water Are Fundamentally Intertwined

See on Scoop.itGreen & Sustainable News

For a long time, we’ve overlooked the inextricable relationship between water and energy use.  Coal, nuclear and natural gas plants use enormous amounts of steam to create electricity.  Producing all of that steam requires 190,000 million gallons of water per day, or 39% of all freshwater withdrawals in the nation.

Duane Tilden‘s insight:

>The longstanding division between energy and water considerations is particularly evident in the case of energy and water management.  These resources are fundamentally intertwined: Energy is used to secure, deliver, treat and distribute water, while water is used (and often degraded) to develop, process and deliver energy.

Despite the inherent connection between the two sectors, energy and water planners routinely make decisions that impact one another without adequately understanding the scientific or policy complexities of the other sector.  This miscommunication often hides joint opportunities for conservation to the detriment of budgets, efficiency, the environment and public health, and inhibits both sectors from fully accounting for the financial, environmental or social effects they have on each other.

This lack of collaboration between energy and water planners is especially dire considering Texas is in midst of an energy shortage that is exacerbated by the multi-year drought.  Without adequate planning, we could someday have to choose between keeping our lights on and turning on the faucet.<

Formal consultation commences on the world’s first purpose built tidal lagoon | Specification Online

See on Scoop.itGreen Building Design – Architecture & Engineering

The formal consultation process has started on the world’s first purpose built tidal lagoon for Swansea Bay, with public exhibitions taking place at 18 locations around the Swansea Bay area until August 5.

Duane Tilden‘s insight:

>The proposed tidal lagoon will have a rated capacity of 240 Megawatts (MW), generating 400GWh net annual output. This is enough electricity for approximately 121,000 homes.

In addition to generating electricity, the £650 million development will also provide visitor facilities and other amenities including art, education, mariculture and sporting/recreational facilities. The seawall is expected to be open to the public during daylight hours for walking, running, cycling etc, though access will be controlled in extreme weather.

LDA Design, the project masterplanners and landscape architects for Swansea Bay Tidal Lagoon, has completed the coordination of exhibition material for the public exhibitions. As part of the formal consultation for the proposed Development Consent Order (DCO) application by Tidal Lagoon (Swansea Bay) plc (TLSB), a new, virtual 3D programme has been prepared, which shows the proposed lagoon in the context of Swansea Bay.  <
