When Comparing Costs of Automotive Lithium-Ion Batteries, Know the Context

May 30, 2020

By Emma Elgqvist, CEMAC Analyst

A photo shows several electric vehicles parked in a parking garage.

When comparing the costs of lithium-ion batteries for electric vehicles, understanding the context is crucial. In the latest CEMAC blog, analyst Emma Elgqvist compares modeled and market prices for Li-ion batteries and observes that market factors—not manufacturing costs—are currently influencing pricing decisions. It's all based on a recent factsheet develop for the Department of Energy.

Currency Fluctuations and Trade

February 23, 2020

By David Keyser, CEMAC Analyst

Chart showing the U.S. balance of trade increasing and China generally decreases.

We hear about currency fluctuations and its possible impact on trade in the business news frequently.

Economic theory indicates that prices and consumption are linked. When prices are low, people usually buy more of a desired good than when prices are high. Part of a price includes the value of the currency with which it is purchased. For example, if the U.S. dollar is less expensive relative to the currency of the trading partner, that partner can use less of their money to purchase goods or services from the United States. Conversely, if the dollar is more expensive they must use more of their currency. (There are many articles published about this topic, including How the Dollar Impacts Commodity Prices.)

Photovoltaics Made in the USA

March 27, 2020

by Sadie Fulton, CEMAC analyst

A map of solar manufacturing capacity in the United States reveals major manufacturing clusters in the Northwest and Great Lakes regions.

The American solar photovoltaic market is dynamic and rapidly growing. In 2016, the U.S. solar industry installed 14.8 gigawatts (GW) of solar, a 97% increase over the capacity installed in 2015. Solar's growth trajectory and increasing market share continue to excite electricity producers and consumers alike. Yet, despite this success, PV manufacturing is not an industry for the faint of heart.

Wind Turbines Made in the USA

April 18, 2020

By Parthiv Kurup and Timothy Remo, CEMAC Analysts

A map of utility-scale wind component manufacturing in the United States show majors concentrations of facilities in the Great Lakes and Midwest regions, with a few other clusters e.g. in Colorado and Texas.

The wind industry in the United States is growing rapidly, supported by a large domestic manufacturing sector. Now, manufacturers are seeking new ways to make their turbines bigger and more efficient. What role could additive manufacturing play in the future of the American wind energy industry? In this blog, CEMAC analysts highlight the state of U.S. wind manufacturing and how new advanced manufacturing technologies such as additive manufacturing could change it.

Hydropower Turbine Market and Trade Values: A closer look at small hydro turbines in the U.S.

December 14, 2016

By Parthiv Kurup, NREL, and Megan Johnson, ORNL

Global map showing the export and import trade flow of small hydropower turbines to and from the U.S., with green lines representing imports, blue lines representing exports, and the thickness of lines representing the value of the trade in dollars.

Hydropower has been a long-term stable power generation source in the U.S. for decades, and research shows there is significant electricity generation potential from powering domestic, non-power hydro dams, which would utilize smaller turbines. This potential growth in the U.S. and international market demand for small hydropower turbines could offer greater opportunities for local and more energy-efficient manufacturing practices, both within the U.S. and for export.

Bio-Based Carbon Fiber: An Exciting New Product, But There's Work to Do

September 29, 2016

By Anelia Milbrandt and Sam Booth, CEMAC

Abstract image of carbon fiber materials being manufactured.

Carbon fiber, also known as graphite fiber, is a lightweight, strong, and flexible material used in both structural applications (load-bearing) and non-structural applications (e.g., thermal insulation). The high cost of precursor materials and manufacturing, however, have kept carbon fiber in a niche market for applications that are mostly limited to high-performance structural products.
