@Risk

Several materials used in the manufacture of clean energy technologies such as wind turbines, electric vehicles, solar cells and energy-efficient lighting are at risk of supply disruptions in the short term, according to a new report released by the US Department of Energy (DOE).

The 2011 Critical Materials Strategy is DOE’s second report on this topic and provides an update to last year’s analysis. After its analysis, the DOE has concluded that:

• Supply challenges for five rare earth elements (REEs) (dysprosium, neodymium, terbium, europium and yttrium) may affect clean energy technology deployment in the years ahead.
• The risks of supply disruptions in the short term will generally decrease in the medium and long term.

The report also includes a discussion of DOE’s strategy to address these critical materials challenges. DOES says its strategy rests on three pillars: (more…)

Scientists at the Joint Research Centre (JRC), the European Commission’s in-house science service, have identified five metals that are both essential for manufacturing low-carbon technologies and at high risk of shortage.

These five metals are: neodymium, dysprosium, indium, tellurium and gallium.

According to the report, titled Critical Metals in Strategic Energy Technologies, the risk of shortage stems from:

• Europe’s dependency on imports (as in the US, virtually the entire European supply of these metals comes from China),
• increasing global demand,
• supply concentration and
• geopolitical issues.

Furthermore, these metals are not easily recyclable or substitutable. (more…)

Many of the digital and “green” technologies that we now take for granted contain certain metals which previously have been of little interest. Consequently, production of these rare earth elements (REEs) is concentrated in a small handful of countries, leaving the global supply at considerable risk.

Just how high is the risk?

A new assessment from the British Geological Survey (BSG) gives us some insight.

BSG’s new ‘Risk List’ ranks the risk to global supply of 52 chemical elements of economic value.  BSG estimated supply risk using the abundance, production and reserves of the element and governance factors for the producing countries and found that: (more…)

US lawmakers are growing impatient to break China’s monopoly on global production of rare earth elements (REEs), a handful of minerals essential to the manufacture of high-tech gadgets and critical to the development of many new “green” technologies.

REEs are actually more abundant than many commonplace industrial metals. In fact, back in 2010, the US Geological Survey (USGS) released a report revealing that 13 million metric tons of rare earths exist within known deposits in 14 US states.

However, REEs are typically very difficult to extract. Consequently, the US has not mined REEs in more than a decade, and now we are completely (100 percent) dependent on foreign sources for REEs, 97 percent of which are provided by China.

Fortunately, there are new signs that perhaps this trend may be beginning to reverse its course. (more…)

In a hearing held by the US House Subcommittee on Energy and Mineral Resources last week, a variety of mining industry stakeholders voiced their concerns about American dependence on foreign mineral imports and emphasized the need for a comprehensive US minerals policy that improves the regulatory approval processes for domestic resources development.

“Without increased domestic exploration, significant declines in US mineral production are unavoidable as present reserves are exhausted. We will continue to ship American jobs overseas and forfeit our economic competitiveness unless we take steps to develop our own mineral resources,” said Subcommittee on Energy and Mineral Resources Chairman Doug Lamborn (CO-05). “Developing our Nation’s mineral resources is not only an integral part of an all-of-the-above energy plan but it will create long-term family wage jobs, stimulate our economy and reduce our foreign dependence on mineral resources.”

The US Geological Survey’s (USGS) Mineral Commodity Summaries, released earlier this year, reports the US is completely (100 percent) dependent on foreign sources for rare earth elements (REE), 97 percent of which are provided by China.

However, in 2010, the USGS released a report revealing 13 million metric tons of REEs exist within known deposits in 14 US states. According to the House Subcommittee, the Obama administration is not doing enough to facilitate utilization of these domestic resources.
