Alfa Laval achieves significant milestone in GCU
Alleima receives gold medal from EcoVadis
EcoVadis is a trusted provider of sustainability ratings and tools for global supply chains , using a methodology based on international standards and supervised by experts . It assesses how companies implement sustainability across their operations . “ We are proud to receive the EcoVadis gold medal , improving from last year ’ s silver . This
reflects our commitment to enhancing sustainability ,” says Johnny Ulander , Sustainability Manager at Alleima . “ EcoVadis helps us evaluate sustainability among suppliers , and our gold rating allows customers to assess us similarly ,” adds Håkan Sundström , Head of Sustainability at Alleima . Alleima minimizes its environmental impact by using recycled steel ( 83 %) and fossil-free electricity , while also managing water usage , chemicals , and by-products like slag and gases . EcoVadis evaluates 21 sustainability criteria across four themes : environment , labour and human rights , ethics , and sustainable procurement . Scoring is based on policies , actions , results , and input from third-party experts and stakeholders .
Alfa Laval has been granted Approval in Principle from DNV for its Gas Combustion Unit ( GCU ) to be used on liquid hydrogen carriers . The AiP affirms the technical feasibility and safety mechanism of the GCU design and concept . The boil-off gas technology is essential for liquid hydrogen carriers , as venting cargo is restricted and a GCU is needed to control tank pressure and temperature to safely combust hydrogen boil-off gas ( BOG ) from a vessel ’ s storage tank . DNV ’ s AiP signifies a major accomplishment for Alfa Laval ’ s hydrogen GCU design . It paves the
way for the development of a GCU prototype that will undergo further testing and type approval to create a safe and efficient system for managing BOG on liquid hydrogen carriers . Unlike Liquefied Natural Gas ( LNG ), hydrogen presents unique challenges for safe and efficient transportation at sea . Its incredibly low boiling point of -253 ° C leads to a higher boil-off rate during transport compared to LNG . Additionally , hydrogen ’ s inherent properties – being light , highly flammable , and easily ignitable – necessitate prioritizing safety in the design of a GCU for hydrogen carriers .
Expansion Joints for Heat Recovery Steam Generators ( HRSGs )
MACOGA has successfully manufactured and supplied a significant quantity of expansion joints specifically designed for Heat Recovery Steam Generators ( HRSGs ). This latest delivery has been made for one of the industry leaders in the HRSG sector , further solidifying MACOGA ’ s commitment to providing highquality , custom-engineered solutions for critical power generation equipment . This achievement highlights its expertise and dedication to supporting major projects in the energy sector . Expansion joints used in Heat Recovery Steam Generators ( HRSGs ) are critical for accommodating thermal expansion , vibrations , and other mechanical stresses in the system .
NewEnergyBlue acquires Inbicon biomass conversion technology
NewEnergyBlue , a cleantechnology designer of biomass refineries that turn agricultural waste into highly decarbonised
biofuels and biochemicals , has finalised its purchase of Inbicon biomass-conversion technology from Ørsted .
NewEnergyBlue ’ s acquisition extends its scope of operations worldwide , includes ownership of Inbicon ’ s international patent portfolio , and conveys global licensing . A previous licensing agreement was exclusive just to the Americas . “ Corn stalks from America , wheat straw from Canada and Europe , sugar bagasse in Brazil and India — all over the world , billions of tons of botanical waste are left behind after annual harvests ,” said Albury Fleitas , president of NewEnergyBlue . “ And on the horizon , perennial grasses grown in the planet ’ s expanding arid regions where food crops no longer thrive . They ’ re all
ideal feedstocks for our biomass refineries , more opportunities than ever to replace fossil fuels and chemicals with next-generation renewables .” NewEnergyBlue biomass refinery ’ s process design utilises Inbicon biotechnology to tightly adjust process thermodynamics and precisely control chemical reactions without caustic additives . One of the by-products is clean water . This smarter design aligns with global environmental and sustainability mandates so essential to meet this decade . Invented in Denmark 25 years ago , Inbicon technology proved its efficacy over a series of critical 10x scale-ups .
