A consortium of European universities and industry has produced new research improving reliability of the combustion process in gas turbines (GT) which can potentially saving operators tens of millions of euros. "Although failure due to flame instability is extremely rare, a single event can cost in excess of €10 million - so research to improve reliability is vital" Professor Jim Kok, project co-ordinator for the Limousine group told Gas to Power Journal.
The US Supreme court has announced it will hear a challenge to the Environmental Protection Agency's (EPA) recent climate directives as the beleaguered coal power generation sector in the country fights the regulation. "Whatever happens will undoubtedly be important for the economic case for new gas-fired generation...what this does is buy some time for coal-fired plants," Trevor Skirkoski, analyst at EnergyAspects told Gas to Power Journal.
LNG buyers in power-hungry Asian countries seek more flexible terms and call for a Henry Hub price element in long-term import contracts in a bid to bring down costs of gas purchase. Almost 70% of global LNG supply is consumed in Asian countries but "it seems at times that we are paying more than we need to," Kogas CEO Jang Seok-hyo said at the World Energy Congress in Daegu, Korea.
Replacing coal-fired power with gas-fueled plants on a wide scale by 2030 would reduce carbon emissions in the power sector by five percent compared to today's levels, according to a Siemens study compiled under the lead of Professor Horst Wildemann at the Technical University of Munich. "Of course, it would be illusionary to replace all coal-fired power plants with gas-fueled units – but the potentials identified are really impressive," he admitted.
Uncompetitive gas markets in Europe could lead to the closure of up to 60% of Europe's gas-fired power plants by 2016, Cap Gemini has warned, causing regional price increases and making power shortages unavoidable. The predictions come as part of the consultancy's annual European Monitoring Centre for Energy Markets report and outline an uncertain future for the industry.
China will use fossil fuels in a low-carbon manner, engage in green growth and work towards energy security as rapid urbanisation continues, Wang Yumin, vice administrator of the National Energy Agency of China said in a keynote speech at the World Energy Congress this morning.
As South Korea transforms into a creative economy "the energy industry is one of the areas where this creative paradigm can shine," Park Geun-hye, President of the Republic of Korea told the World Energy Congress today, referring to her signature policy targets to utilise enhanced technology for energy storage and demand side management to reduce peak-load power consumption.
Fuel savings of several percentage points may be possible for gas turbines operating under partial load conditions thanks to new research at the University of South Carolina. “Better understanding of flow dynamics can help to boost operating performance for a wide range of fuels,” Dr. Tanvir Farouk, lead investigator said, speaking to Gas to Power Journal.
A risk analysis of gas-fired power generation versus nuclear suggests that the current low costs for gas power operators may disguise long-term risks, according to consultancy EnergyPath. A probabilistic comparison of the investment risks shows that "gas has shown great volatility in the past and this volatility must be recognized as part of investment strategies," Thomas Retson, analyst at EnergyPath, told Gas to Power Journal.
Investment in global energy infrastructure in Asia-Pacific is forecast to grow to $11.7 trillion by 2035, with the bulk spent on power and heat generation in China and India. Though there is no lack of local financing, but investors shy away from regulatory risk as power and gas prices are still regulated in many Asian markets, warns Seethapathy Chander, deputy director general of ADB
In the face of a rise in Korea's electricity consumption by a quarter by 2030, the power industry is forecast to reduce the share of coal from currently 40 percent to around 16 percent by 2030 in a bid to diversify energy sources and reduce carbon emission, a study carried out by Siemens shows.
If Korea were to dispense completely with coal-fired power plants in favour of modern gas-fuelled units by 2030, the sector's carbon emissions would drop by a further third, and the country could save 9 million tons of imported oil equivalent per year, the study finds.
Tapping the searing 2,000°C heat of gas turbine combustion with new man made materials may add fuel efficiency, said Professor Andrey Prokofiev at Vienna University of Technology (TU Vienna). "While according to the second law of thermodynamics some heat will always be lost, we can turn part of this waste heat into useful electricity."
The European Commission has launched a €5.85 billion funding push to diversify gas and power infrastructure across the continent, as part of its long-term infrastructure vision. Financing will go to 248 projects, with approximately 140 aimed at "diversification of gas supplies...to significantly increase the gas system's flexibility and resilience in the short and medium term" according to a statement from the commission.
Meeting Asia-Pacific's energy needs will require investments of $11.7 trillion through 2035 in a business-as usual scenario, but may swell to about $19.9 trillion under an alternative approach with deployment of more costly super-critical coal- and efficient gas-fired generation technology and higher renewable penetration, a report launched by the Asian Development Bank (ADB) shows.
Natural gas will surpass oil and coal as the primary fossil fuel consumed by industries and power producers around 2030, provided and expansion of pipeline, storage and a virtual LNG pipeline to allow for more decentralised gas-fired generation, forecast Steve Bolze, GE president and CEO.
