Siemens Energy AG is considering designing a new turbine to replace a system responsible for billions of euros in losses as one option to shore up its beleaguered wind energy business, people familiar with the matter said.

Die Siemens Energy AG erwägt die Entwicklung einer neuen Turbinengeneration, um das pannengeplagte System 5.X abzulösen, das für Verluste in Milliardenhöhe verantwortlich ist, berichten mit den Diskussionen vertraute Insider.

Adler Group SA’s €6 billion ($6.4 billion) debt restructuring faced fresh legal scrutiny in a London court as some creditors appealed the deal that saved the embattled German real estate firm from slipping into insolvency.

The cities of Amsterdam, Stockholm and Nantes offer good examples of how meaningful progress towards decarbonising the building sector can be achieved, while advancing the EU's broader climate objectives, writes Irene García.

In this research, a life cycle inventory (LCI) is developed for tungsten carbide–cobalt (WC-Co) coatings deposited via atmospheric plasma spray (APS), high-velocity oxy-fuel (HVOF), and cold gas spray (CGS) techniques. For the APS process, a mixture of Ar/H2 was used, while the HVOF process was fueled by H2. The carrier gas for CGS was N2. This study aims to determine and quantify the inputs (consumption of inputs and materials) and outputs (emissions to air, soil, water, and waste generation) that could be used in the life cycle analysis (LCA) of these processes. The dataset produced will allow users to estimate the environmental impacts of these processes using WC-Co feedstock powder. To obtain a complete and detailed LCI, measurements of electrical energy, gas, WC-CO powder, and alumina powder consumption were performed (the use of alumina was for sandblasting). Furthermore, emissions like carbon dioxide (CO2), carbon monoxide (CO), and noise were also measured. This practice allowed us to determine the input/output process quantities. For the first time, it was possible to obtain LCI data for the APS, HVOF, and CGS deposition processes using WC-12Co as a feedstock powder, allowing access to the LCI data to a broader audience. Comparisons were made between APS, HVOF, and CGS processes in terms of consumption and emissions. It was determined that the APS process consumes more electrical energy and that its deposition efficiency is higher than the other processes, while the HVOF process consumes a large amount of H2, which makes the process costlier. CGS has comparatively low electricity consumption, high N2 consumption, and low deposition efficiency. The APS, HVOF, and CGS processes analyzed in this study do not emit CO, and CO2 emissions are negligible.
