As the US gas turbine fleet grows older, more and more plant managers consider Human Machine Interface (HMI) upgrades, according to Frank Hoegler, vice president sales Americas for Turbine Technology Services (TTS) "Aging HMI hardware can become a burden on plant operations, so plant managers are actively seeking to avoid these issues by upgrading their HMIs," he told Gas to Power Journal.
With south-east Asia's energy demand set to increase 40% by 2020, with 90% of the increase happening in SE Asia, technology like advanced gas path (AGP) helps enhance installed and new power generation assets, says Fintan Tuffy, general manager for fleet analytics and performance management at GE Power & Water. GE expanded its AGP technology to 9F-3, 9E gas turbines – the backbone of most of its installations in Southeast Asia.
A new circulating fluidised bed (CFB) boiler was introduced by Alstom at Power-Gen Asia in Thailand, Wednesday. The unit offers 660 MW or more in output, based on the type of fuel used, and relies on the efficiency of ultra-supercritical (USC) steam conditions and the flexibility of circulating fluidised beds.
As renewable, intermittent wind and solar energy replaces traditional base load coal-fired and nuclear energy in Europe, the need for substantial sources of fast-start and cost-effective backup gas power increases, says Swift Tarbell, PW Power Systems Area Director for Europe. Following the sale of the first FT4000 SWIFTPAC to Exelon, PWPS is showcasing the technology in Europe.
Gas turbine lifetimes could double thanks to new sensor monitoring technology developed by researchers at Cambridge University. The tested sensors monitor turbine operation at higher temperatures more accurately and help reduce fuel consumption between 0.5% and 1.5% as "improved accuracy allows greater control over the amount of fuel ingress," project lead Dr Michele Scervini told Gas to Power Journal.
Varying fuel gas composition presents a challenge to gas-to-power equipment such as internal combustion (IC) engines, gas turbines and fuel cell based machines as it impacts performance and component lifetime as well as meeting emissions regulations. By measuring the optical fingerprints of C1-C5 alkanes, the Precisive 5 Gas Analyzer enables real-time and high-accuracy fuel gas analysis, says founder and president, Vidi Saptari.
Gina McCarthy, administrator of the US Environmental Protection Agency (EPA) has laid down the first nationwide limits on carbon emissions for new power plants in the Climate Action Plan, with CCS requirements handing new gas-fired projects a win over coal. The new rule caps emissions of carbon dioxide for large gas-fired turbines at 1,000 lb/MWh, while it caps new coal plants and small natural gas-fired turbines at 1,100 lb/MWh.
Funding has been announced to develop new technology focused on carbon capture and storage (CCS) specifically for gas-powered UK plants. A request for proposals has been announced by the Energy Technologies Institute, a public-private partnership, to invest in a project which is expected to start in the middle of next year.
A pilot power-to-gas (PTG) project in Germany is being undertaken by E.ON, that converts renewable electricity into hydrogen gas. The gas is injected into the regional gas grid, easing the heavy loading of wind and solar power on electric grids, such as is present in Germany and around Europe, at the same time providing 'renewable' gas feed.
Fuel cells have traditionally been associated with renewable technologies, as a means of offsetting generation intermittency problems, but as technology has reached maturity the range of applications and technologies has grown. Fuel cells increasingly provide opportunities for distributed downstream electricity, heat and gas generation and support local production, as well as easing grid requirements securing overall supply stability.
