Hitachi has been issued a patent for a low NOx gas turbine combustor for hydrogen combustion, especially in IGCC applications. Below is comments on the technology from Jeff Phillips of EPRI:
"I looked at the brief description of the Hitachi patent and it is different from nitrogen dilution. They are trying an approach called rich/lean combustion to try to stay away from the high NOx production
region (which occurs right around stoichiometric combustion where you have just enough oxygen to react with all of the fuel).
At the 2011 Electric Power Conference and Exhibition, Fernanado De Albuquerque, Plant Modernization Division Manager, Companhia Paranaense de Energia (Copel), located in Curitiba, Brazil, discussed Brazil’s outlook for natural gas fired projects. Up until the late 1900s, 95% of the nation’s power generation was hydro. In 2001 and 2002, Brazil suffered brownouts and was subject to power rationing. Shortly thereafter an emergency plan was put in place to construct 49 thermal power stations.
John Shelk, president and CEO, Electric Power Supply Assn., was keynote speaker at the 13th annual Electric Power Conference and Exhibition in Rosemont, IL. He urged competitiveness and innovation in the power markets and cited reliability as one of the future challenges facing the industry. Maintaining a power surplus was the best way to ensure reliability, he said.
Environmental issues are also a challenge. What’s needed, he said, were analyses of the impact of U.S. EPA rules on the power industry.
Russia’s programme of wide-scale modernisation and expansion of its energy infrastructure is proving a powerful incentive for the UK packaging specialist Centrax as it moves to build on its significant market presence in Europe by establishing its first service centre in Russia. “The Centrax facility here in St Petersburg will enable us to manage site activities throughout the Russian federation,” reports Vladimir Skvortsov, General Director of Centrax RUS.
Ocean Power Technologies, Inc., a leading wave energy technology company, has announced the commencement of ocean trials of the first of its new generation utility-scale PowerBuoy device, the PB150. With a peak-rated power output of 150 kW – equivalent to the energy consumption of approximately 150 homes – the PB150 is the largest and most powerful wave power device designed by OPT to date.
Howden has announced that it has agreed to acquire the entire issued share capital of Thomassen Compression Systems BV ("Thomassen"). The combination of Howden and Thomassen creates a global company capable of supplying a comprehensive range of hydrogen compressors including a full suite of piston compressors with capability up to 25MW and 600 bar and diaphragm compressors with capability up to 3000 bar. This is expected to bring market opportunities not currently available to either company.
The Clean Energy Technology Development Center of Southern Research Institute in Durham, North Carolina, has developed a technology that combines both coal and biomass feedstocks for use in Integrated Gasification Combined Cycle systems. Use of biomass—as a supplement to coal—could allow power stations to take credit for the carbon dioxide that plants and trees take out of the atmosphere as they grow and mature. The program was sponsored by the U.S. Department of Energy (DOE), with additional financial support from Southern Research and TK Energi.
