India ’ s floating solar power plant in Ramagundam excels Locus PI and Veolia collaborate on bio-based technologies
NTPC in 1978 came up with its first thermal unit in the town to generate power and supply to the southern state . Very soon , it became synonymous with Ramagundam . NTPC has grown into a 2640 MW capacity plant , one of its largest sites in the country . In mid 2022 , Ramagundam , now part of the Peddapalli district added a new first with the commissioning of the country ’ s largest Floating Solar Power Plant as of date by the NTPC . It ’ s about 5 km from the town . The 100 MW , Solar Photovoltaic ( PV ) unit executed by the BHEL is a 4-5 hour drive from Hyderabad
and is quite scenic , spread over the waters of the balancing reservoir of the NTPC Power plant . A unique feature of the project is that all the electrical equipment is floating on the reservoir . Engineers constructed ferro-cement floating platforms ( 15.5 m x8 m x 1.2 m ) on which Inverter , Transformer & HT breaker is placed . In just over six months into its operational phase , the project has raised the expectations of setting up similar plants and rapidly increasing the generation of a clean , renewable , and environmentally friendly power in the long term .
Locus Performance Ingredients ( Locus PI ) and Veolia Water Technologies & Solutions have announced their exclusive collaboration that will focus on developing new bio-based solutions tailored to address process , water , and wastewater sustainability and performance challenges . Both companies will combine their relevant expertise and resources : Veolia ’ s expansive water treatment technology and process experience renowned for helping customers optimize water resources and overcome process challenges ; and Locus PI ’ s proprietary fermentation and large-scale biosurfactant production capabilities . The sustainable water and process treatment ingredients will feature
Locus PI ’ s line of high-performance , multifunctional sophorolipids a type of biosurfactant in the glycolipid class — as a starting point . These bio-derived surfactants have many unique advantages over fossil-based and other bio-based surfactants typically used in water and process treatment and are produced from renewable agricultural materials in a carbon-neutral production process . Locus PI ’ s biosurfactants are also USDA certified for containing 100 % biobased content and meet global regulatory compliance requirements such as REACH registration , Toxic Substances Control Act ( TSCA ), and CleanGredients approval for use in Safer Choicecertified products , including for direct release applications .
GE demonstrates a scalable DAC system for CO 2 removal
Following successful testing of its first Direct Air Capture ( DAC ) prototype unit for carbon
dioxide ( CO 2
) removal in the lab , GE announced it is planning larger scale demonstrations in
2024 . GE Research and the GE Vernova business have been partnering closely with the U . S . Department of Energy ( DOE ), the Advanced Research Projects Agency ( ARPA-E ), and a host of other industry and academic research partners to accelerate new advancements in CO 2 removal . GE ’ s progress with DAC is one of more than a dozen technologies that the company is highlighting at the 2023 ARPA-E Innovation Summit , which is taking place this week in Washington D . C . Decarbonization , renewables acceleration , and electrification are key topics that GE leaders will be talking about as they engage with more than 2,100 top energy thought leaders from across the nation and beyond .
GE ’ s Carbon Capture Technology Breakout Team has developed a unique DAC system that couples its decades of experience designing thermal management solutions and heat exchangers for its power turbines and jet engine platforms with deep chemistry and material systems expertise to develop innovative sorbent materials for CO 2 capture . With GE ’ s DAC system , the thermal management design provides an optimal environment for the sorbent materials to remove
CO 2 from the air . The team is employing a similar approach in a project with the Defense Advanced Research Projects Agency ( DARPA ) to capture clean , potable water from extremely arid , desert-like air .
Fuel-saving simulations flow from STREAM
Clean Sky 2 ’ s STREAM has developed a simulation capability that enables the surface roughness characteristics from Additive Manufacturing to be factored into the design of heat exchangers used in aircraft engines . This weightsaving production process is vital for conserving energy , curbing fuelburn
, and cutting emissions . The STREAM project has evaluated and compiled invaluable data identifying key parameters and methodologies for modelling 3D printed heat exchangers , taking into account the unique surface characteristics of additive manufactured components .
This will help accelerate the availability of lighter and more thermally efficient heat exchangers that can be better integrated into the engine environment , leading to improved fuel consumption in aircraft engines . Clean Sky 2 ’ s STREAM ( Simulation of Turbulence and RoughnEss in Additive Manufactured parts )
project has successfully devised novel modelling strategies for the performance prediction of Additive-Manufactured ( AM ) heat exchangers . These are devices used to transfer heat between a source and a working fluid and can be used in aircraft engines for cooling and / or heating requirements .
