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

Thermoelectrics enters fast track

Aug 2 – Thermoelectrics cools, heats, makes electricity and sense. ID TechEx sees a real possibility of thermoelectric generators becoming viable in geothermal energy and other high-power applications. New research scrutinizes 90 companies involved, from patents to research papers, product offerings, and financials.

Mining site used for solar PV

July 30 – German lignite operator Leag takes advantage of the country's coal phase-out by using part of the Jänschwalde opencast mine to build a 400 MW solar power. Construction for the ‘Energy Park Bohrau’ is slated to begin in 2023 with a view to go into operation in 2024.

Howden powers methanol plant

July 29 – Howden will deliver a hydrogen compressor to Johnson Matthey to serve the world’s first methanol plant that harnesses energy from the wind, in Patagonia, Chile. The Haru Oni project will deliver around 900,000 litres per year of e-methanol as early as 2022 and will be scaled up to 550 million litres of e-fuels per year by 2026.

Bloom SOFCs to power micro plant in South Korea

July 28 – California-based Bloom Energy, in cooperation with SK ecoplant, will install solid oxide fuel cells (SOFCs) in a combined heat and power (CHP) plant in Donghae City, South Korea. The CHP will provide heat and warm water for the nearby Bukpyung sports center. Construction on the project is slated to start this autumn.

Shanghai Electric to digitalise factories

July 27 – Shanghai Electric has entered a partnership with AI Investment Fund at the WAIC 2021 conference to provide digital solutions to industrial parks and medical institutions. Yang Hong, Vice President of Shanghai Electric said the aim is to help industries to minimise emissions and waste while maintaining low unit costs.
