DOE selects 7 gasification projects for funding; focus on reducing cost of coal conversion

July 15, 2015

The Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) has selected seven projects to receive funding through NETL’s Gasification System Program. This program supports a wide range of research and development activities aimed at improving fuel and product versatility, efficiency, and economics of gasification processes.

The projects conducted through this program are geared toward reducing the cost of coal conversion and mitigating the environmental impacts of fossil-fueled power generation. The funded research projects fall under two subtopic areas: development of gasification technologies applicable to in situ bio-gasification of coal to methane; and the development of low cost advanced air separation technologies that can produce oxygen for use in coal gasification processes.

DOE selects 16 research projects for more than $19M in funding to advance Solid Oxide Fuel Cell technology

July 14, 2015

The Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) has selected 16 solid oxide fuel cell (SOFC) technology research projects for a total of more than $19 million ($19,358,915) in funding.

In Fiscal Year (FY) 2015, NETL issued two funding opportunities announcements (FOAs) to support programs that enable the development and deployment of this energy technology. The projects selected under the two FOAs will receive funding through NETL’s Solid Oxide Fuel Cell Program. The FOAs were awarded with two primary objectives: to design, construct, and field-test a SOFC prototype system; and to support innovations that improve the reliability, robustness, and endurance of SOFC cell and stack technology.

DOE to award $20M to projects to recover rare earth elements from coal and coal byproducts

June 29, 2015

The US Department of Energy (DOE) has issued a funding opportunity (DE-FOA-0001202) that will award an estimated $20 million to projects quickly to develop bench scale and pilot scale projects for recovering Rare Earth Elements (REE)—a set of seventeen chemical elements in the periodic table and key components of electronics and renewable energy technologies—from coal and coal byproducts.

The DOE has begun investigating the economic feasibility of recovery of REEs from domestic United States coal and coal byproducts. n FY14, DOE’s National Energy Technology Laboratory (NETL) conducted a preliminary, short-term, baseline field evaluation of coal and coal by-products as potential domestic resources of REEs. NETL has characterized a number of REE-bearing samples of coal and coal related materials, and posted the associated results and reports here.

Kyoto team develops two-stage process for direct liquefaction of low-rank coal and biomass under mild conditions

May 11, 2015

Researchers at Kyoto University in Japan have proposed a novel two-stage process to convert low-rank coals or biomass wastes under mild conditions to high-quality liquid fuel. A paper describing the process, which combines a degradative solvent extraction method they had developed earlier with the liquefaction of the resulting soluble, appears in the ACS journal Energy & Fuels.

One of the issues hampering the development of direct liquefaction of low-grade carbonaceous resources—such as low-rank coals and biomass wastes—to produce liquid fuel is their oxygen content. In low rank coals, cross-linking reactions among oxygen functional groups form large-molecular-weight compounds at temperatures lower than the liquefaction temperature; the oxygen-functional-group-derived cross-links may change to stronger carbon−carbon covalent linkages, suppressing the formation of light hydrocarbons.

Lux: alternative fuels in China could replace up to 483B GGE in 2020; coal-to-ethanol conversion offers near-term potential

April 14, 2015

China’s shift toward alternative fuels in order to cut its reliance on imported oil is creating large opportunities, notably in natural gas vehicles (NGVs) and in the conversion of coal to ethanol, according to a new report from Lux Research. China is seeking to reduce its imports of oil from the current 50% of domestic demand. Further, its plans to limit coal-fired power plants due to pollution problems, means that oversupplied coal is available for conversion to alternative fuels.

Lux Research analysts evaluated China’s alternative fuels landscape to assess opportunities and identified potential domestic partners across diverse feedstocks, technologies and fuels. Among their findings:

DOE awarding about $16M to four projects for advanced gasification systems; focus on coal

November 06, 2014

The US Department of Energy (DOE) has selected four projects to receive funding for next-generation gasification systems. Awardees will receive approximately $16 million to advance the gasification process, which converts carbon-based materials such as coal into syngas for use as power, chemicals, hydrogen, and transportation fuels.

Gasification plants have the potential for greater power generation efficiency and environmental performance than conventional coal-fired plants, and serve as the basis for integrated gasification combined cycle (IGCC) advanced power generation and co-production plants capable of 90% CO2 capture. The funded research projects will focus on developing technologies that can significantly reduce the cost of producing hydrogen-rich syngas derived from fossil fuels, enabling coal resources to both improve US economic competitiveness and provide global environmental benefits, DOE said.

A team at Rice University has created a hybrid material combining graphene quantum dots (GQDs) and graphene platelets that can—depending upon its formulation—outperform platinum as a catalyst for fuel cells.

The material showed an oxygen reduction reaction (ORR) of about 15 millivolts more in positive onset potential—the start of the reaction—and 70% larger current density than platinum-based catalysts. The materials required to make the flake-like hybrids are much cheaper, too, said Dr. James Tour, whose lab created GQDs from coal last year. A paper on their new work is published in the journal ACS Nano.

DOE to award $9M to promote consensus on future fossil energy technologies

July 20, 2014

The US Department of Energy’s (DOE) Office of Fossil Energy will award $9 million over five years to organizations to assist it in building domestic and international consensus on future fossil energy technologies (DE-FOA-0001111). The Funding Opportunity Announcement (FOA) anticipates two awards being made: the first for $7 million in the area of Carbon Capture and Storage (CCS) and fossil-fuel-based Clean Energy Systems (CES); the second for $2 million in the area of international oil and natural gas.

One of the key missions of the Office of Fossil Energy is to “ensure the nation can continue to rely on traditional resources for clean, secure and affordable energy while enhancing environmental protection.” In pursuit of this, the Office provides outreach and education to many stakeholders, including the general public, in order to allow them to make educated choices about energy.
