On the market for nearly a decade, the Siemens H-class gas turbine has now exceeded one-million fired hours in commercial operation. The output rating of the SGT5-8000H turbine has grown over the years from 375 MW to 450 MW, with efficiency improvements to over 61% in combined cycle operation.

Burning hydrogen (H2) in a combined-cycle power plant is a step towards dispatchable, totally CO2-free power generation. However, the main challenge of H2 combustion lies in its properties, notably its increased reactivity. In contrast to natural gas, the flame position moves upstream during H2 combustion, which increases the risk of flashback.

Researchers from Kawasaki Heavy Industries (KHI) and B&B Agema have been looking at a novel design approach – Nekomimi film cooling – to further increase temperatures at the combustor exit and high-pressure turbine stage inlet. The aim is to boost efficiency without putting too much strain on vanes and blades, considering that modern turbine stage inlet temperatures exceed the melting points of turbine blade materials.

Caterpillar Energy Solutions has just launched a new 170B 50-Hertz series of generator sets with a power output ranging from 1.3 MW to 2.3 MW. The 20-cylinder version is available now, with 12 and 16 cylinders set to come out later in 2019.

Mitsubishi Electric Corp has developed two technologies for gas-insulated switchgears (GIS): arc-cooling that improves the interruption of electrical current in sulfur-fluoride GIS by 25%, and high-density dielectric coating that improves insulation performance by 30% in high-voltage conductors.

Bacteria and microbes living in oxygen-deprived environments – deep within mines, at the bottom of lakes or in the human gut – have evolved way of breathing that involves excreting and pumping out electrons. These microbes can actually produce electricity and MIT researchers are striving to harness these microbial power plants to run fuel cells.

Toshiba Energy Systems & Solutions has set out an internal business re-design project to accelerate a digital transformation. Eager to simplify its set-up, Toshiba ESS will consolidate its nuclear, thermal, hydro and services units into a new Power System Division, while transformation, distribution and energy aggregation will be folded into a Grid Aggregation Division as of April 1.
