Supplier strategies and responses to institutional drivers for an emerging energy technology
This paper investigates the role of suppliers of a new energy technology, when the market for that technology continues to be in a state of flux, and is characterised by continued regulatory and institutional developments. This paper first summarises the institutional drivers resulting in the widely divergent diffusion of distributed generation (DG) based on natural gas engines in the Netherlands ...

Development of Pre-Turbo Catalyst for Natural Gas Engines
Distributed power generation is an efficient method for reducing CO2 emissions through the elimination of transmission losses. Co-generation has similar benefits with higher thermal efficiency. Natural gas engines are very popular for these applications. Unfortunately, these engines emit significant levels of methane, which is a greenhouse gas. Reduction of methane emissions would greatly ...

Demand for submarine cables is growing
With the increasing shortage of global oil and natural gas energy, the exploitation of land has begun to shift to the marine field on a large scale. The scale of offshore oil and natural gas engineering projects is expanding. It is necessary to carry out power and communication transmission from land to offshore oil platforms and between platforms, as well as feedback and control of technical ...

Switching from diesel to CNG or LNG fueled engines
Gas engine fact: there are more than 28,000 engines in service in the refuse industry worldwide. Over the past several years, more and more American refuse companies have been considering the change from diesel to either CNG (compressed natural gas) or LNG (liquefied natural gas) fueled engines in their collection fleets. This article will discuss some components to consider before transitioning ...

A study on the amount of pilot injection and its effects on rich and lean boundaries of the premixed CNG/air mixture for a CNG/diesel dual-fuel engine
A sequential port injection, lean-burn, fully electronically-controlled compressed natural gas (CNG)/diesel dual-fuel engine has been developed based on a turbo-charged and inter-cooled direct injection (D.I.) diesel engine. During the optimisation of engine overall performance, the effects of pilot diesel and premixed CNG/air mixture equivalence ratio on emissions (CO, HC, NOx, soot), knocking, ...

Putting a Lid on Catalyst Issues
While it is a given that emissions control technology must first and foremost remove harmful constituents from the engine exhaust gas stream, it is equally true that they must also be able to operate in the real world, where durability, reliability and serviceability are critical. It was with those facts in mind that DCL International Inc., the Concord, Ontario, Canada, supplier of advanced ...

Study of the performance and exhaust emissions of a spark-ignited engine operating on syngas fuel
To resolve the problem of depletion of petroleum based liquid fuels, various solutions have been proposed. One of them is the use of gaseous fuels that are generated from the gasification of woods, namely syngas or wood-gas fuels, as full supplement fuels in spark ignition internal combustion (IC) engines. This fuel consists of nearly 40% combustible gases, mainly hydrogen and carbon monoxide ...

The isoengine: realisation of a high-efficiency power cycle based on isothermal compression
A novel high-efficiency internal combustion engine for power generation and direct-drive applications is being developed. Distillate-fuelled power plants in units of 7 MW electrical output are predicted to reach a net electrical efficiency of 60%. An efficiency of 58% is targeted for the gas-fired version. This compares with a net electrical efficiency of about 45% for advanced reciprocating ...

Carbon capture could be costly and risky
There’s bad news for those who think that carbon dioxide can be removed from the atmosphere and stored deep in the Earth’s rocks. Even if carbon capture is possible, sequestration in the rocks is fraught because the gas can find multiple ways to escape, according to a report by a team from Penn State University, US, in the International Journal of Greenhouse Gas Control. Back in the ...
