Japan's Fourth Strategic Energy Plan

Stephen H. Crolius September 19, 2016

The Cabinet of the Government of Japan adopted the country’s Fourth Strategic Energy Plan in April 2014. The Plan includes a Strategy for Hydrogen & Fuel Cells which is being executed by the Ministry of Economy, Trade and Industry (METI). The accompanying H2/FC Road Map includes an investigation of three materials that can carry the energy embodied in molecular hydrogen: liquid hydrogen, organic hydrides such as methylcyclohexane, and ammonia.

Study on Reduced Chemical Mechanisms of Ammonia / Methane Combustion under Gas Turbine Conditions

Trevor Brown September 14, 2016

On September 1st, academic journal Energy & Fuels published a new paper that features research coming out of the UK's Cardiff University and Ireland's University of Limerick. This study demonstrates a "reduced mechanism" for simulating the "robust numerical analyses with detailed chemistry" necessary for the "industrial implementation" of ammonia in gas turbine combustion for "future power generation." Here's the abstract:

Numerical investigation of combustion characteristics of ammonia-air mixtures under high pressure lean conditions

Hadi NozariArif Karabeyoğlu

In this numerical study we investigate the combustion characteristics of ammonia-air mixtures at elevated pressure and lean conditions which are encountered in gas turbine combustors. The Konnov mechanism is implemented to predict the laminar burning velocity, autoignition, species concentrations and the sensitivity analysis of ammonia decomposition and laminar flame speed. A laminar premixed freely propagating flame model is implemented to calculate burning velocity, mole fractions of species, and contribution of reactions in molar conversion of specific species. Also a homogenous reactor model is used to analyze the temporal mole fraction of radicals and ignition delay time. Effects of adding hydrogen…

A demonstration test with the aim to show the potential of ammonia-fired power plant is planned using a micro gas turbine. 50kW class turbine system firing kerosene is selected as a base model. A standard combustor is replaced with a prototype combustor which enables a bi-fuel supply of kerosene and ammonia gas. Diffusion combustion is employed to the prototype combustor due to its flame stability. Demonstration test of co-firing of kerosene and ammonia gas was achieved to check the functionality of the each component of the micro gas turbine. The gas turbine started firing kerosene and increased its electric power…

Using Local Green Energy and Ammonia to Power Gas Turbine Generators

Brian Evans

Beginning in the 1950s, a fundamental shift in the way information was electronically expressed and manipulated led to the “digital revolution” that has transformed — is still transforming — information systems and many major industries and that has given rise to the internet, social media, and instant very-low-cost communication (like this website). A good case can be made that a similar “revolution” is beginning — has already begun — to transform the energy systems upon which we all depend. This presentation will address the use of anhydrous (water-free) ammonia, NH3, as a realistic option for making a fundamental shift in…
