General Electric has installed its first DLN1.0+ Ultra Low NOx combustion upgrade globally at nine GE 9E gas turbines at five power stations in Shenzen Province, China. The upgrade reduces NOx emissions from about 25ppm to about 7.5ppm, in line with the Shenzhen government’s ‘Blue Sky’ campaign.

Engineers at GE, together with the Southwestern Research Institute (SwRI) have designed, built and tested what is said to be the highest-temperature supercritical carbon dioxide (sCO2) turbine in the world. The turbine, featuring a multi-stage axial flow sCO2 hot gas turbo-expander, was developed with a $6.8 million U.S. government grant on top of $3 million industry funding.

Manufacturers of power generation equipment like MAN Energy Solutions see hydrogen as a future alternative fuel source for its gas turbines, though switching from methane to hydrogen a conversion of the turbine combustion chamber to allow for higher firing temperatures. Demand for H2-solutions keeps rising as states like California aim for 100% clean energy by 2045.

Intermittency issues of wind and solar power supply are feared to jeopardize the stability of the U.S. power grid. To remedy this issue scientist at the Massachusetts Institute of Technology (MIT) have developed an “air-breathing” battery storage that, at the cheapest, run about $100/kWh and functions only in certain locations.

Swiss-based ABB and Rolls-Royce of the UK have entered a global partnership on microgrid technology and advanced automation, particularly for hybrid power systems. Mircogrids are critical to integrate rising volumes of renewable energy and benefit utilities and industrial users alike.

The Indian manufacturer ELGi Equipments is showcasing its new AB ‘Always Better’ air compressor series, a breakthrough in oil free compressed air technology, at Hannover Messe ComVac 2019 this week. Air Alert, an IoT-based, machine-monitoring platform is also on display at the trade show.

Siemens is supporting a study by the German Fraunhofer Institute for Energy Economics (IEE), and the French Grenoble Ecole de Management, on SF6 and F-gas free alternatives for medium voltage (MV) gas-insulated switchgear installations in Europe. The research – funded by Siemens and Schneider Electric Industries – has started in mid-March and is running until early 2020.

Uniper, formed in 2016 as a spin-off of E.ON's fossil power plant assets, has started producing methane gas from excess wind and solar power through electrolysis at its Falkenhagen Power-to-Gas (P2G) plant. The project demonstrates it is feasible to produce entirely green energy with qualities identical to natural gas.

MAN Energy Solutions is targeting ASEAN and Africa with its new integrated LNG-to-Power solutions. “We have new projects under development mainly in Asia and western- and northern Africa. But this is a business we are still building,” said business development manager Carsten Dommermuth. “For the entire project development up to the commercial operating date we allocate a time frame of 3 to 5 years.”

U.S. engine manufacturer Cummins will present its newly launched HSK78G gas generators at the Energy Hannover trade show on April 1-5, where the series will be showcased in Europe for the first time. With a power density from 1.6 to 2.0 MW from a 78L engine, the HSK78G generator can reach up to 44.2% electrical efficiency on 50Hz models.

China’s State Power Investment Corp (SPIC) and Siemens have signed a strategic partnership framework agreement, building on the companies' earlier agreed technology collaboration for heavy-duty gas turbines. The contract was sealed in Beijing today by SPIC chairman Qian Zhimin and Siemens CEO Joe Kaeser. The aim is to create a China-based supplier eco-system.

Eddyfi Technologies, a Canadian developer of inspection technology based in Québec, has launched Spyne – a non-destructive ECA-adaptable screening and testing screening tool that can detect cracks, fatigue and corrosion faster and with a higher probability than traditional tools. Spyne is applicable on pipelines, vessels or power generation equipment.

With more than a third of Germany’s electricity generated by renewables, the number of Power-to-X projects has surged in a bid to make use of this intermittent energy supply. Over 35 plants with over 50 kW of installed electrolysis capacity will be in operation by 2022 in Germany alone, according to forecasts by certification service provider TÜV SÜD.

As renewable energy combined with batteries are becoming part of modular power networks, natural gas the ideal fossil fuel source to supplement these power networks, says Craig Wilkins, Director Prime Power at Cummins. Headquartered in Indiana, U.S., the manufacturer has responded to the intermittency challenge of renewable power supply with the launch of its HSK78G gas-powered generator.

SSE, one of the UK’s Big Six energy companies with more than 7 million customers, has chosen Contigo’s energy nomination and scheduling platform, enVoy, for electronic data transfer with National Grid. Since going live, the system already handled approximately two million submissions.

News in Brief

Evol LNG helps power Australian gold mine

June 18 – Kirkalocka Gold Mine in Western Australia will use Evol LNG to fuel Zenith Energy’s 14.5 MW power station with regasified natural gas starting from September 2019. The mine is run by Adaman Resources and had been relying on diesel to cover its energy needs. Based on the current diesel price, Adaman Resources expects to reduce fuel costs by more than A$13 million (US$9 million) during the first six years of operation of the new onsite LNG-to-Power plant.

Shell Energy ordered to refund overcharged UK customers

June 17 – UK energy regulator Ofgem has ordered Shell Energy Retail to refund around 12000 customers who were overcharged after the Government’s cap on gas and electricity prices came into force in January. Shell Energy Retail s agreed to refund these customers by paying £29,000 in compensation (£5 per fuel), and also pay an additional £200,000 into Ofgem’s voluntary redress fund.

BASF enters battery market

June 14 – German chemical company BASF is using NGK Insulators’ sodium sulfur batteries as its entry point into the energy market. The Japanese manufacturer NGK is currently the only maker of the large-scale sodium sulfur (NAS) batteries, capable to store several hours of energy. A joint project in northern Germany uses NAS batteries that store energy for five hours, while a recently completed project in Abu Dhabi using 108MW / 648MWh of the systems with a full six hours storage duration.
