June 26, 2013 More than 1,300 gigawatts (GW) of wind and solar power generation capacity are expected to come online in the next 10 years, creating an unprecedented amount of instability on the gri…

Duane Tilden‘s insight:

>“Several of the major markets for renewables, including Germany, Japan, and the United States, have enacted rules or legislation encouraging the adoption of energy storage systems for the purpose of integrating variable energy sources onto the grid,” says Anissa Dehamna, senior research analyst with Navigant Research.  “These market incentives come in various forms, including outright subsidies for ESS adoption, reforms that change how variable generation is compensated, and adjustments to connection requirements for variable power plants.”

In particular, changes to the compensation arrangements for variable power generation will have significant influence on the market for ESSs for solar and wind.  Compensation mechanisms have changed drastically over the past 10 years, according to the report, and many compensation schemes have grandfather clauses—meaning that older wind and solar systems have much different compensation rates and structures than newer systems coming online.<

Utilities fear what they cannot control with community solar – PV-Tech

See on Scoop.it – Green Energy Technologies & Development

Utilities love solar. Or at least they love utility-scale solar, i.e. installations they can own or control through power purchase agreements.

Duane Tilden‘s insight:

>”People like solar and the utility can play a really useful role in bringing solar into a community. But you do have to deal with some issues in terms of how to take advantage of the tax incentives. That can really change the cost of the programme. To take advantage of the tax code, the system has to be located on your property.

[…]

“We’ve seen some prices as low as 5c-6c per kWh once the tax depreciation and tax advantages have been taken by an entity that has that tax appetite. For those who are subscribing this is a resource for the future and many years out that would be a hedge.”

Ultimately, one of the biggest appeals of community solar is the value proposition and that does not always come down to the cheapest rate: communities want power sourced as locally as possible. Green pricing failed to gain mass appeal 10 years ago because consumers were being sold ‘clean power’ generated by wind two states away.<

Integrating Building into the Smart Grid

It will take time to get from point A, today’s grid and building technologies and power markets to point B, a Smart Grid with intelligent buildings and transactive markets, but it can be done.

Duane Tilden‘s insight:

>Transactive energy will play a critical defining role in grid modernization and shaping the Smart Grid.  Buildings, as noted in last week’s article consume 40% of the nation’s energy.  And while building owners can justify purchase decisions on energy savings as well as sustainability values, there’s another crucial factor for building owners to invest in technologies that reduce energy use and deliver self-generation.  That reason is to address the increasing vulnerability of the electrical grid to momentary and sustained power outages to both natural and human causes.

Buildings and their occupants are impacted by grid-related power outages.  The negative impacts range from reduced work productivity and decreased occupant safety and health to reductions in lifestyle standards.  Just like real estate values are higher for green buildings with LEED recognition, in the future, buildings that are grid-hardened may command premium prices because they preserve delivery of services regardless of grid status.  It is a compelling new variable in value propositions for tenants and occupants.<

Go geothermal to maximize energy efficiency

See on Scoop.it – Green Building Design – Architecture & Engineering

A huge leap in energy conservation, and undoubtedly the most innovative of all energy saving tactics has its origins in the earth itself

Duane Tilden‘s insight:

>This geothermal system provides a quiet environment with a consistent temperature throughout the house or building; efficiently comfortable in the winter, and cool in the summer. The heating or cooling mode can be changed with a simple switch on the indoor thermostat. With virtually no use of fossil fuel, costs for heating and cooling for a typical 4,000-square-foot home can run as low as $2 per day/$60 per month.<

US team’s battery ‘breakthrough’

See on Scoop.it – Green Energy Technologies & Development

Researchers believe they have found a way to radically shrink the size of batteries while offering the same amount of power and faster recharges than at present.

Duane Tilden‘s insight:

>The scientists’ “breakthrough” involved finding a new way to integrate the anode and cathode at the microscale.

“The battery electrodes have small intertwined fingers that reach into each other,” project leader Prof William King told the BBC.

“That does a couple of things. It allows us to make the battery have a very high surface area even though the overall battery volume is extremely small.

A cross-section of the battery reveals the 3D-design of the research project’s anodes and cathodes

“And it gets the two halves of the battery very close together so the ions and electrons do not have far to flow.

“Because we’ve reduced the flowing distance of the ions and electrons we can get the energy out much faster.”<

Transactive, distributed energy markets hold promise | Intelligent Utility

Transactive energy markets hold the promise to achieve economic efficiency and reliability across the bulk power system and distribution networks.  This research area was identified in the Caltech Resnick Sustainability Institute’s Grid2020 report released last fall, and was the topic of the third discussion of the series in April 2013.

Duane Tilden‘s insight:

>Significant untapped potential exists to leverage a new class of flexible mixed distributed assets (e.g., distributed generation, responsive demand, storage, power electronics and electric vehicles), what has been called DR 2.0, to manage the power system. But, this requires changes in both market designs and grid operations.  […]

Current wholesale market rules are significant barriers to participation as they effectively do not distinguish a 500 MW power plant from a 5kW electric vehicle battery. This is very unfortunate, as the technology to tap these smaller resources and create significant value for customers is available today. Heather Sanders, Director, DER Policy at CAISO shared that, “a challenge is to create market participation rules that meet operators’ needs for reliability, but also facilitate customer value opportunities.” <

New Wyoming lithium deposit could meet all U.S. demand

The U.S. currently imports more than 80% of the lithium it uses, with the silvery metal winding up in batteries from cell phones to electric cars.

Duane Tilden‘s insight:

“University of Wyoming researchers found the lithium while studying the idea of storing carbon dioxide under ground in the Rock Springs Uplift, a geologic formation in southwest Wyoming. University of Wyoming Carbon Management Institute director Ron Surdam stated that the lithium was found in underground brine. Surdam estimated the located deposit at roughly 228,000 tons in a 25-square-mile area. Extrapolating the data, Surdam said as the uplift covered roughly 2,000 square miles, there could be up to 18 million tons of lithium there, worth up to roughly $500 billion at current market prices.”
