Pre-engineered combined heat and power (CHP) systems can provide customers with a variety of benefits when compared to customized CHP systems, Mike McElligott, sales engineer at European Power Systems (EPS) told Gas to Power Journal at COGEN Canada's annual seminar in Calgary. "The standardized design means that there is no custom work necessary. Because there are thousands of these units out there, the standardized unit is proven and the customer is not going to be in the position of having to work the bugs out of a custom system," he said.

The key challenge in choosing an engine or turbine for a combined heat and power (CHP) system is to efficiently bring together thermal energy demand with systems that produce mechanical or electrical power, Manfred Klein, independent energy consultant and former Canadian federal government staffer, told Gas to Power Journal at this year's COGEN Canada annual seminar in Calgary.

"One question that the plant operator needs to ask is to what degree the plant is a thermal operation or a power operation? In this sense, managing heat demand will ultimately determine overall system efficiency," he said.

The world's largest concentrating solar plant – the 280 MW Solana Generating Station– is being built about 70 miles southwest of Phoenix, Arizona, in close proximity to a substantial fossil backup plant – the 2,334 MW gas-fired combined-cycle Gila River Power Station.
As a rising volume of intermittent renewable power sources are being added to the grid, power producers have a growing interest in combining it with realising new fossil power plant project, particularly gas-fired ones.

At two US-based gas-fired combined cycle plants, controllability at the plants was a major issue, the responsible plant manager told Gas to Power Journal on condition of anonymity. Large natural gas swings caused large boiler pressure swings, which "created a situation where the load was swinging around a lot more than it needed to be".

A total of 11 European companies have joined together in a project initiated by energy consulting and testing & certification company DNV KEMA to develop the concept of Power-to-Gas (P2G) in the newly established North Sea Power to Gas Platform. P2G is a method of converting surplus renewable electricity into gaseous energy carriers such as hydrogen or methane that can be stored in the natural gas grid.

The successful deployment of carbon capture and storage technologies (CCS) in power generation will be crucial to achieving the UK's climate change goal of an 80 percent reduction in emissions by 2050, says a new report from Carbon Connect. "Electricity supply will likely need to rise significantly by 2050, and decarbonising the power sector beyond 2030 without CCS would be expensive and politically challenging," the report reads.

Success in the micro Combined Heat and Power (CHP) market is dependent on having a standardised, efficient and cost effective generation unit, Jean-Pierre Van Wingen, General Manager of E. Van Wingen (EVW) told COGEN Europe's annual conference in Brussels. "It is essential that you have a standard product. It needs to be competitive and have a low price and that is only possible when you have a concept that can be produced in volume," he said, adding that "production in volume also allows you to have standardized service and decrease marketing costs."

MAN Diesel & Turbo has supplied a custom-made steam turbine for the 100MW Shams 1 solar thermal power plant in Abu Dhabi, owned by the Shams Power Company – a joint venture between Masdar, Total and Abengoa Solar. Unlike conventional solar plants using photovoltaics where solar cells convert the sun's energy directly into electricity, the plant utilises concentrated solar power (CSP) technology to work with fossil fuels.

Increased market penetration of energy efficient Combined Heat and Power (CHP) installations can help the EU reduce its energy imports and drive economic recovery, Paul Hodson, Head of Unit Energy Efficiency at the European Commission's DG Energy told this year's COGEN Europe annual conference in Brussels.

The world's largest concentrating solar plant – the 280 MW Solana Generating Station, located in southwest of Arizona, US – is being built beside a substantial fossil backup plant – the 2,334 MW gas-fired combined-cycle Gila River Power Station.

At two US-based gas-fired combined cycle plants, controllability at the plants was a major issue, the responsible plant manager told Gas to Power Journal on condition of anonymity. Large natural gas swings caused large boiler pressure swings, which "created a situation where the load was swinging around a lot more than it needed to be".

GE has launched a new corrosion protection technology for refinery steam systems, based on its Steamate low salt amine (LSA) product series that have been specifically designed for refinery boiler and steam condensate systems.

Alstom has been awarded a €120 million contract by Centrica Energy for gas turbine maintenance services at the 1260MW South Humber Bank combined-cycle power plant (CCPP) in North East Lincolnshire, England. The agreement covers five Alstom GT13E2 gas turbines installed at the plant over the next seven years.

Laser Metal Deposition (LMD) could be used to reliably and cost effectively repair steam turbine and industrial gas turbine components, Roger Fairclough, Principal Engineer at TWI Ltd, told Gas to Power Journal at this year's IMechE Steam Turbine and Generator User Group in Coventry. "If the LMD process is further developed for power station applications, it will be able to produce a good useable component for steam or industrial gas turbines, making it feasible for applications where the spare part needed is not available, out of production, quite expensive or the repair is relatively small compared to the initial cost of the component," he said.

Both horizontal and vertical heat recovery steam generators (HRSG) have their own specific advantages, which makes it important for power plant operators to choose the best HRSG for their facility based on the circumstances appropriate for each type, Pascal Fontaine, CMI Energy Marketing Manager told Gas to Power Journal in an interview. In general, horizontal HRSGs are best suited for cogeneration while vertical HRSGs are best suited for combined-cycle duty although both can be used in either.

News in Brief

Ferrybridge C gets demolished

Oct 15 – Four cooling towers at the Ferrybridge Power Station have been taken down as the coal-fired power station will make way to a new, high-efficiency gas power station. Operator SSE shut down the 500 MW Ferrybridge C unit in March 2016 and now started to tear it down.

Global energy storage tops 10 GW by 2025

Oct 14 – The global market for grid-connected energy storage will grow by 6,900 MW, or 16.6% to reach over 10,500 MW by the end of 2025, according to Reportlinker.com. Germany will add over 267 MW energy storage installations over the next five to six years, while 330 MW will come from other European markets. These numbers are dwarfed by China, where up to 1,200 MW energy storage units could be connected to the grid by 2025.
