DOE soliciting projects in advanced coal gasification for high carbon-capture power production and/or liquid fuels
February 26, 2014
The US DOE is soliciting (DE-FOA-0001051) projects for up to $10 million in awards to target technological advancements to lower the cost of producing hydrogen and/or high-hydrogen syngas from coal for use in 90% carbon capture power generation and/or gasification-based liquid (transportation) fuel production: methanol or diesel. Liquid fuel production must be GHG equivalent to conventional petroleum-based processes.
The work is also designed to assure significant reduction in the cost of coal conversion and environmental impacts, enabling coal resources to both improve US economic competitiveness and provide environmental benefits over the globe, according to the DOE.
Kawasaki Heavy to build first ocean-going liquid hydrogen tanker with demo in 2017; H2 for transport, industry, power in Japan

The Nikkei reports that Kawasaki Heavy Industries Ltd. (KHI) will build the first ocean-going ships to carry liquefied hydrogen (LH2), with plans for a demonstration test by 2017 in which liquefied hydrogen will be shipped from the state of Victoria in Australia to Japan. The project will cost ¥60 billion (US$610 million), according to the report.
As part of Japan’s WE-NET (World Energy Network) research program of the New Sunshine Project begun in 1993, Kawasaki and its other industrial colleagues in Japan have been considering the large-scale marine transportation of liquid hydrogen for some time (e.g., Abe et al., 1998). KHI has previously discussed the concept of such a hydrogen-carrying vessel as part of its Business Vision 2020.
EPA proposes CO2 emission standards for new fossil fuel-fired power plants
September 20, 2013
The US Environmental Protection Agency (EPA) has proposed Clean Air Act standards to reduce CO2 emissions from fossil-fuel fired power plants (electric utility generating units, EGUs). For purposes of this rule, fossil fuel-fired EGUs include utility boilers, IGCC units and certain natural gas-fired stationary combustion turbine EGUs that generate electricity for sale and are larger than 25 megawatts (MW). In addition, EPA said it is working with state, tribal, and local governments, industry and labor leaders, non-profits, and others to establish CO2 standards for existing power plants.
The proposed rulemaking establishes separate standards for natural gas and coal plants. The proposed limits for natural gas units are based on the performance of modern natural gas combined cycle (NGCC) units. New large (>850 mmBtu/h) natural gas-fired turbines would need to meet a limit of 1,000 pounds of CO2 per megawatt-hour, while new small (≤850mmBtu/h) natural gas-fired turbines would need to meet a limit of 1,100 pounds of CO2 per megawatt-hour.
