Engine+ Hybrid Energy, Wärtsilä's latest technology solution, pairs gas-fuelled engines with energy management systems and storage. It forms a fully integrated system that provides reliable power supply for operators and power producers of islanded grids. Payback periods can be as short as two years, the Finish manufacturer claims.
Six partners – Ansaldo Thomassen, Delft University, OPRA Turbines, Vattenfall, Nouryon and EMMTEC – have been granted €500 million by the Dutch Government for research into ‘High Hydrogen Gas Turbine Retrofit to Eliminate Carbon Emissions’. The aim is to develop a CO2-free hydrogen value chain, in line with the EU Energy Roadmap 2050.
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.
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.
