Energy Newsbriefs Blog

This current awareness service is prepared by the WSU Energy Program Library with funding from the U.S. Department of Energy State Energy Program. This information is provided for energy professionals and interested members of the public to highlight recent energy-related news, articles, and reports that discuss energy efficiency, energy conservation, and renewable sources of energy in engineering and policy circles.

 


Fine Tuning Oil-Free Air Compressors and Purification at a Pharmaceutical Plant

Compressed Air Best Practices, Apr. 2017, by Don van Ormer.

"A pharmaceutical product manufacturer spends an estimated $137,443 annually on electricity to operate the oil-free air compressors in its compressed air system. The compressed air system operates well and is providing the level of purification required.  Our team visited the plant and identified a group of projects which could reduce compressed air demand and reduce energy costs by $42,248 – or 31% of current use. The objective of this article, however, will be to illustrate the review we did of all the supply-side equipment.  This includes the oil-free air compressors, dryers, filters, drains, oil-water separators and breathing air systems."

Modular Chillers Reduce Energy, Ownership Costs, Ensure Uptime

"At the Buck Institute for Research on Aging in Novato, Calif., an independent biomedical research facility focused on the connection between aging and chronic disease, prepared to embark on a 60,000-sq-ft expansion of its 185,000-sq-ft research facility, [they] sought a HVAC solution that not only could provide added capacity, but would optimize energy efficiency, minimize overall consumption, and reduce total cost of ownership. With the facility running on 100 percent single-pass outdoor air and requiring six air changes per hour—any HVAC-component downtime would require a complete shutdown of the facility—the Buck Institute needed a solution that also would minimize downtime—both during construction and post-occupancy—with built-in redundancies."

Geothermal Heating, Cooling System Helping Winery Crush Energy Costs

"Known for the first genuine ice wine produced in the United States and made broadly available, Hunt Country Vineyards, located on a 170-acre farm in the Finger Lakes region of New York, is no stranger to accolades. But wines are not all for which the vintner has been recognized. In 2015, Hunt Country Vineyards, along with Penn Yan, N.Y.-based Moravec Geothermal, received the New York Geothermal Energy Organization’s Top Job award for its geothermal heating and cooling system. Installed in 2012, the system supports the sustainability goals that are so important to the Hunt family."

CLEAResult, 2017.
https://www.clearesult.com/insights/whitepapers/guide-to-smart-thermostats/

"...this paper outlines available products and services and shares the collective expertise of CLEAResult’s energy analysts, building science consultants and program managers who have first-hand knowledge of how smart thermostats work and how they can help save energy."


The Distributed Wind Cost Taxonomy

National Renewable Energy Laboratory (NREL), Mar. 2017.
http://www.nrel.gov/docs/fy17osti/67992.pdf

"To date, there has been no standard method or tool to analyze the installed and operational costs for distributed wind turbine systems. This report describes the development of a classification system, or taxonomy, for distributed wind turbine project costs. The taxonomy establishes a framework to help collect, sort, and compare distributed wind cost data that mirrors how the industry categorizes information. The taxonomy organizes costs so they can be aggregated from installers, developers, vendors, and other sources without losing cost details."

Compressed Air Savings with Nozzles or Blowers

Compressed Air Best Practices, Apr. 2017, by Jerry Zolkowski.
http://www.airbestpractices.com/system-assessments/end-uses/compressed-air-savings-nozzles-or-blowers

"Compressed air is used as a convenient and often necessary source of air flow to perform blow-offs, cooling, or drying.  And since compressed air is a costly utility, a frequent recommendation in this magazine and audits is to reduce the compressed air use by using high efficiency engineered nozzles.  Using these nozzles is a good practice as they are designed in a way that uses the compressed air to accelerate the surrounding air to deliver the same mass transfer effect as a standard nozzle (or tube) with a much larger orifice."

Using Probability of Exceedance to Compare the Resource Risk of Renewable and Gas-Fired Generation

Lawrence Berkeley National Laboratory (LBNL), Mar. 2017, by Mark Bolinger.
https://emp.lbl.gov/sites/default/files/lbnl-1007269.pdf

"This paper presents a new framework, grounded in statistical concepts related to probability of exceedance (and confidence intervals more broadly), to incorporate resource risk into decision-making processes. This framework recognizes that the same probability of exceedance concepts that are regularly used to characterize the uncertainty around annual energy production for wind and solar projects can also be applied to natural gas price projections, allowing one to develop a probabilistic range of projections for not only wind and solar capacity factors, but also natural gas prices."

An Assessment of the Economic Potential of Offshore Wind in the United States from 2015 to 2030

National Renewable Energy Laboratory (NREL), Mar. 2017.
http://www.nrel.gov/docs/fy17osti/67675.pdf/

"This study describes an assessment of the site-specific variation of levelized cost of energy (LCOE) and levelized avoided cost of energy (LACE) to understand the economic potential of fixed-bottom and floating offshore wind technologies in major U.S. coastal areas between 2015 and 2030."

Strategies for Peak Shaving and Power Security

Forester Daily News, Mar. 2017, by Ed Ritchie.
http://foresternetwork.com/daily/energy/strategies-for-peak-shaving-and-power-security/

"In Part 1 of a 5-part series, author Ed Ritchie takes readers through the process of understanding reliable energy strategies like peak shaving for business applications. Through this series, he explains the multifaceted components of commercial building energy systems that might include utilities analysis software, commercial generators, and other onsite technologies important in maintaining reliable power generation."
