The use of Tomo-Lithographic Molding (TOMO) manufacturing technology, developed by Mikro Systems, in a range of gas turbine machinery improves the cooling capabilities of gas turbines and increases overall efficiency."[When] applied to gas turbines, [TOMO technology] enables more sophisticated airfoil designs with improved cooling characteristics, which leads to higher operating temperatures and improved efficiency," Tim Rokita, Siemens representative told Gas to Power Journal.

A crowd sourcing initiative to map the world's thermal power plants known as the Ventus Project has been launched by Arizona State University (ASU) under the lead of Dr. Kevin Robert Gurney. The initiative encourages users to contribute information about power plants including location, fuel type and CO2 emissions via pin placements on Google Maps and form filling.

Investing in higher efficiency filters can help improve turbine performance in cogeneration units by reducing fouling, Jim Benson, senior product engineer at Camfil Farr Power Systems told Gas to Power Journal at COGEN Canada's annual seminar in Calgary. "The operator can make up for the cost and pressure drop of a higher quality filter through the operational benefits provided by the product," he said.

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.

German utilities invest record amounts

Jan 21 – Energy companies in Germany invested a record €20.5 billion in 2021, and the industry association BDEW expects capital expenditure will stay high throughout 2022. Out of the total sum, €4.3 billion were invested in electricity generation plants, €9.9 billion in transmission and distribution plants and €1.2 billion in other assets, such as metering points and information technology.

H2-powered plant for French Guiana

Jan 20 – Siemens Energy will set up a hybrid plant to supply stable baseload electricity to 10,000 households in French Guiana. An intelligent combination of 55 MW photovoltaics, an electrolyser to produce green hydrogen, fuel cells and energy storage is scheduled to be commissioned in the autumn of 2023.

Decarbonising UK homes

Jan 19 – Just 9 million hot water cylinders are currently installed in British homes, leaving a gap of 18 million homes whose heating would need to be decarbonised for the UK to meet Net Zero.

This gap in in government policy, which could result in unnecessary costs to consumers.
