Microturbines take on the market - Cogeneration & On-Site Power Production Magazine

Microturbines take on the market - Cogeneration & On-Site Power Production Magazine | Micro generation - Energy & Power systems | Scoop.it

COSPP spoke with two microturbine firms at opposite ends of the market spectrum - one the established market leader, with an 85% market share; one a new sector entrant with significant market potential - to discover the commonalities and differences in how each has strategised its market approach.

Jim Crouse, Executive Vice-President of Sales and Marketing at microturbine manufacturer Capstone Turbine, says he 'would agree with' Navigant's analysis. Although increased shale gas availability in the US 'hasn't been as impactful on the cogen side,' he notes, it has 'certainly been helpful from an oil and gas perspective.'


Once MTT had developed its technology, he continues, 'we needed to focus on a particular market. We had chosen micro-cogeneration, a common and large market, and also a market where the specific advantages of the microturbine are very important.' Micro-cogeneration, he says, has 'been around for 10 to 15 years now with no real breakthrough: the available systems are too expensive and/or the maintenance costs are too high.

Ultrafast heat conduction can manipulate nanoscale magnets - Nanotechnology News (press release)

Ultrafast heat conduction can manipulate nanoscale magnets - Nanotechnology News (press release) | Micro generation - Energy & Power systems | Scoop.it

Researchers at the University of Illinois at Urbana-Champaign have uncovered physical mechanisms allowing the manipulation of magnetic information with heat. These new phenomena rely on the transport of thermal energy, in contrast to the conventional application of magnetic fields, providing a new, and highly desirable way to manipulate magnetization at the nanoscale.

"In our study, we make use of the fact that a heat current passing through a magnetic material creates a separation of electron spins. This process creates a current of magnetic dipoles that we use to manipulate the orientation of a second magnetic layer," said David Cahill, a Donald B. Willett Professor of Engineering and head of the Department of Materials Science and Engineering at Illinois. "The physics of separating spins with heat currents is related to the operation of thermocouples and the thermoelectric generators that power deep space probes. In those thermoelectric devices, a heat current causes a separation of electrical charges. That separation of electrical charge can then be used to measure a temperature or provide electrical power."

Groundbreaking Solspaces Solar Thermal System Stores a Boat Load of Heat Energy

Groundbreaking Solspaces Solar Thermal System Stores a Boat Load of Heat Energy | Micro generation - Energy & Power systems | Scoop.it
University of Stuttgart begin preparations to test their Solspaces system that promises to be a five times more efficient than standard solar thermal systems.

It might seem preposterous that anything can store heat year round but the University of Stuttgart’s sorbent tanks utilize a thermochemical heat storage tank with three to four times the energy density of water. Combined with improved thermal insulation, the system is much less susceptible to heat loss than conventional solar thermal systems that use water. On top of addressing the issue of heat retention, the Solspaces concept could potentially reduce the space required for solar heating systems.

The key secret behind the Solspace system is a microporous mineral zeolite, which boasts the abilities of high energy density, low drying temperature, and hold large amounts of water vapor. In the cold winter months this mineral absorbs humidity from the moist air flowing through its reservoir. The water vapor binds with the sorbent material to produce heat and warm the building.

During the summer months the process is reversed when the reservoir heats air to 356 degrees Fahrenheit. The high heat, of course, dries out the water vapor preparing the Solspaces to store heat for the winter again.

Obscure Electrochemical Technology Could Make Residential Cogeneration ... - Greentech Media

Obscure Electrochemical Technology Could Make Residential Cogeneration ... - Greentech Media | Micro generation - Energy & Power systems | Scoop.it

NanoConversion Technologies strives for economical micro-CHP. The technology employed by this startup is the alkali-metal thermal-to-electric converter (AMTEC), invented by Ford in the 1960s. (NanoConversion actually purchased the remnants of the Ford technology and is using some of that vintage equipment today.) The device takes 850°C heat as an input and produces direct current electrical power and thermal heating power at 200°C, at potentially high efficiencies of up to 30 percent, according to Staskus, and when using the heat, over 90 percent. Because it's a closed system, the company claims that it is not subject to the fouling and reliability issues that can afflict fuel cells when contaminants in natural gas compromise the fuel-cell stack and "coke the anode." Because it has no moving parts, it was targeted for 15-year deep space missions with plutonium as the heat source. The device makes use of a thermodynamic cycle of expanding and condensing sodium; the work generated by the expansion of sodium vapor is converted into electric power. Staskus likened it to a fuel cell where the fuel is burned outside of the unit, calling it "a fuel cell that doesn't die." This is how the company breaks down the device's operation: Input heat vaporizes sodium Ion transport through BASE creates DC current The heat sink condenses sodium and delivers thermal power The electromagnetic pump returns sodium to the evaporator

The distributed energy storage industry described in one chart

The distributed energy storage industry described in one chart | Micro generation - Energy & Power systems | Scoop.it
Energy storage itself is complex, but the market's challenges boil down to two easy-to-describe problems.

Battery-based energy storage can play a valuable enabling role in renewable energy adoption, but storage also can do much more. Services such as peak shifting, backup power and ancillary grid services are a small subset of the larger matrix of potential future values that batteries can provide, but storage is still too expensive to cost-effectively provide these services in most U.S. markets.

However, energy storage may be reaching a tipping point. For example, analysts at GTM project that 318 MW of distributed solar plus storage may be installed by 2018. Also, California’s mandate to procure 1.3 GW of storage, combined with the Tesla Gigafactory and the general trend of moving towards prosumer-based electricity markets, is a testament to the size of the potential market.

Thanks to these projections and no shortage of media coverage (by our count, over 40 energy storage articles have been released over the past two months alone), an outsider could be led to believe that distributed storage, by participating in several kinds of electricity markets using a number of product configurations, is capable of solving many of our electricity system ills.

House Works: Storage heaters could cut power costs in half

House Works: Storage heaters could cut power costs in half | Micro generation - Energy & Power systems | Scoop.it
Smart units use electricity when rates are low then heat a space when it's needed, avoiding costly peak prices.

 

Storage heaters use electricity to heat internal bricks while power is cheap, then switch off and radiate that heat to the surrounding room during peak rate times. All else being equal, this can save about 50 per cent in energy costs, depending on the time-of-day pricing schedule where you live.

Inventor Guido Fetta describes EMdrive related propellentless Cannae drive aka Q drive system

Inventor Guido Fetta describes EMdrive related propellentless Cannae drive aka Q drive system | Micro generation - Energy & Power systems | Scoop.it
Guido Fetta describes created unbalanced electromagnetic forces within the chamber. Guido says summing the lorentz forces has a propellentless force.
Guido Fetta, inventor of the Emdrive related Q-Drive.

Fetta, an independent inventor with a background in chemical engineering, explains that the drive is a “superconducting resonating cavity.” An imbalance in the cavity, Fetta says, creates thrust.

Fetta had tested a superconducting version of the "Q-drive" or Cannae drive on 13 January 2011 several yearsprior to the Eagleworks test campaign. The RF resonant cavity was suspended inside a liquid helium-filled dewar. The weight of the cavity was monitored by load cells. Fetta theorized that when the device was activated and produced upward thrust, the load cells would detect the thrust as change in weight. When the Cannae drive was energized by sending 10.5 watt power pulses of 1047.335 MHz RF power into the resonant cavity there was a reduction in compressive force on the load cells consistent with thrust of 8-10 mN. The results have not been published in the scientific literature, but were posted on Cannae LLC's website.

The Reactors That Will Revolutionize Nuclear Energy - Wall Street Journal (blog)

The Reactors That Will Revolutionize Nuclear Energy - Wall Street Journal (blog) | Micro generation - Energy & Power systems | Scoop.it

CHRISTINE TODD WHITMAN: We’re at a turning point in energy. The U.S. should be a leader in mitigating climate change and meeting a nearly 30% increase in U.S. demand for electricity projected by 2040.

 

Nonetheless, renewable-energy technologies will continue to advance, as will other carbon-free power sources like nuclear energy. The nuclear industry is developing new technology that will be up and running inside of 10 years—a smaller reactor option built at much lower capital costs.

Now in the testing process, the first small modular reactors (SMRs) could be powering American homes beginning around 2025. SMRs produce up to 300 megawatts of electricity–enough to power 238,000 homes, according to the U.S. Energy Information Administration. SMRs, like today’s nuclear energy facilities, produce electricity without producing carbon emissions or other pollutants. Unlike today’s facilities, SMRs will be built in factories and shipped to sites for installation. Plus, they can be built in modules to more closely follow increases in the demand for electricity.

Breakthrough Solution Harvests Energy from Wastewater Treatment Plants ... - AZoCleantech

Breakthrough Solution Harvests Energy from Wastewater Treatment Plants ... - AZoCleantech | Micro generation - Energy & Power systems | Scoop.it
The EU project SOFCOM is coordinated by Politecnico di Torino. The project developed a break-through solution to transform the organic waste collected in wastewater treatment plants into valuable energy products through the use of high-efficiency fuel cell technology.

A novel process has been designed, built and tested to produce electricity and heat from the biogas generated from the sludge that is fed to anaerobic digesters within the WWTP. Along with combined electricity and heat production (CHP), two additional products are generated: filtered water and clean CO2 that is recycled to grow algae so that the carbon that is originally contained in biogas is made available again as a fuel.

The prototype plant that demonstrates the feasibility of the SOFCOM concept has been presented today during the conference “Patrimonio idrico, risorse rinnovabili e ambiente. Il presente e il futuro della depurazione in Europa”, an event held in Torino and organized by SMAT Spa, which is partner of SOFCOM.

The prototype plant – Massimo Santarelli explains, Professor at the Department of Energy of Politecnico di Torino and project coordinator – “foresees an integrated poly-generating energy system that uses renewable fuels (digester gas from WWPT and bio-syngas from wood gasification) in high-efficiency fuel cell electrochemical generators that allows for the complete recovery and re-use of CO2 so to close the carbon cycle of the plant”.

The term SOFC (Solid Oxide Fuel Cell) refers to the specific fuel cell technology exploited in the project. SOFC generators operate at around 800 °C and are in fact the most efficient fuel cell devices that can be directly fed with methane fuel, syngas or biogas (as in the case of SOFCOM).

The core component of the SOFCOM plant is the fuel cell stack reactor where biogas is transformed to electricity through efficient electrochemical reactions instead of combustion reactions that take place in less efficient internal combustion engines (ICEs). The overall fuel cell electrical efficiency is >50% when running on biogas and the only exhausts of the plant are pure CO2 and water. Compared to ICEs, the efficiency is 10-20 percentage points higher and with virtually zero emissions.

Someday we may be heating homes and businesses with personal computers - PRI

Someday we may be heating homes and businesses with personal computers - PRI | Micro generation - Energy & Power systems | Scoop.it
A new technology is on the horizon that could make the burning of gas, oil and wood to heat homes obsolete: A new company called Project Exergy is developing a way to capture the waste heat from computing to keep our houses warm.

 

Orsini and his collaborators have created a prototype computer, called Henry — a “liquid-cooled, high-performance computer” that makes significantly more heat than a typical computer. Henry is slightly bigger than a normal tower PC and made only from off-the-shelf parts. “There is no Star Trek technology in this thing,” Orsini says. “It's made out of things that you could go buy from the computer store today.”

There is, however, an additional component that works with the computer: a thermal storage tank. This tank is filled with phase change materials that hold significantly more heat than, for example, a typical hot-water heater, Orsini says.

Phase change materials are materials that store and release latent heat. Typically, they store heat by undergoing a solid-liquid phase transformation. Orsini was able to store heated water in Henry’s thermal storage tanks at 200 degrees Fahrenheit

Submerged bags of air could turn wind and solar power into round-the-clock resources

With the worldwide proliferation of wind- and solar-generated power, the fickleness of these renewable sources is a problem crying out for a good solution. A Canadian start-up called Hydrostor thinks it has an answer: air-filled bags.

In August, the Toronto company plans to sink several large balloonlike bags into Lake Ontario, and then, using electricity from Toronto Hydro’s grid to run a compressor, it will fill the bags with air. Later, when the utility needs electricity, the air will be emptied from the bags and run through a turboexpander, which uses the expanding air to drive a turbine. The result will be the world’s first commercial facility for underwater compressed-air energy storage.

Drivers waste a lot of time in traffic, and also energy. Company founder Ralph Black describes it as a series of cartridges fitted with vertical pumps, similar in design to a stand-up bicycle pump. They’re buried in the road surface inline and connected by a 1.5 to 2.5-inch high bar covered by a flexible membrane that compresses the pumps as cars roll over it. The air is collected in a roadside tank then sent at a constant pressure to an air motor that runs a generator, which can power things directly, charge storage batteries, or feed it into the grid.
