A new 1,000-kilowatt gas engine cogeneration (CHP) system will launch on November 1, jointly developed by Mitsubishi Heavy Industries (MHI) and Tokyo Gas Co. The engine employed is an improved version of MHI's previous 930kW gas CHP system and has been re-engineered to optimise output and efficiency.
Asian countries have taken the lead in producing methane hydrate – a new unconventional gas source, with first offshore production led by Japan Oil, Gas and Metals National Corporation (JOGMEC). Todd Alhart, media relations director, global research for gas turbine manufacturer GE, says that once production fine-tuned, there would be no technical barriers to use of the gaseous methane in gas-fired power plant generation.
GE's largest gas engine distributor, Clarke Energy, has introduced Trigeneration as a form cogeneration combined with high-tech cooling for industrial processes in hot countries like Tunisia, Australia and India. The cost benefit analysis of the system kicks in when temperatures blaze, whether it's for refrigeration or for air conditioning, according to Group Marketing and Compliance Manager, Alexander Marshall.
Fuel savings of 1-2% for combined cycle gas plants (CCGT) may be achieved thanks to research into the uses of hydrophobic surfaces conducted at the Massachusetts Institute of Technology (MIT). GE Research estimates suggest the development could eventually save industry $2.5 billion a year. "This technology can reduce the size of the condenser, reduce coolant pressure drop, and save money on capital cost and maintenance," Nenad Miljkovic, a researcher in the MIT team said, speaking to Gas to Power Journal.
The Energy Technologies Institute (ETI), a public-private partnership between energy and engineering companies and the UK Government, has mapped out a plan to add more district combined heat and power (CHP) capacity with a view to decarbonise the grid. One of its central projects is its Smart Systems and Heat (SSH) Programme, which is looking at ways to improve availability and delivery of efficient heating across the UK.
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.
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.
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."
Flexible rather than conventional gas generation could save Britain between £380 million to £550 million by 2020 and up to £1.54 billion by 2030 alone through reduced balancing costs incurred by National Grid, research commissioned by Wärtsilä through Redpoint Energy and Imperial College London shows. The modelling is based on replacing 4.8GW of conventional CCGTs with 4.8GW of gas-fired Smart Power Generation.
A new wave of innovation, bringing greater connectivity of turbine assets, could lead to savings of up to $7 billion a year, GE research finds. Improved monitoring of components and better access to data about plant operations could cut the estimated 52 million labour-hours a year required to maintain gas and steam turbines worldwide.
A subsidiary of French utility, EDF, has started using radio-frequency identification (RFID) tags to track turbine parts used for repairs and maintenance in gas power plants. The Centre d'Exploitation des Turbines à Combustion (CETAC) is responsible for maintaining EDF's gas turbine assets and has so far tagged 5,000 items within its inventory.
