GA-ASI signs new MoU with Conflux
Unigel and thyssenkrupp nucera sign MoU
thyssenkrupp nucera and Unigel have signed a Memorandum of Understanding ( MoU ) to increase the capacity of the green hydrogen plant that Unigel is developing in Bahia , Brazil , from 60 MW to 240 MW of water electrolysis . The signing ceremony was held in Belo Horizonte , during the visit of the German Federal Minister for Economic Affairs and Climate Action , Dr . Robert Habeck . This is a key step for both companies to continue their good collaboration to accelerate the green transformation through
the development of the green hydrogen economy worldwide . Unigel ’ s facility will be the first industrial-scale green hydrogen plant in Brazil . It is planned to be delivered at the end of the year . In the first phase , the plant will have a total water electrolysis capacity of 60 MW with thyssenkrupp nucera standard electrolyzers and an initial production capacity of 10,000 tons / year of green hydrogen and 60,000 tons / year of green ammonia . The new plant will be an important stimulus for the development of the entire region .
In an effort to further advance its Additive Manufacturing capability , General Atomics Aeronautical Systems , Inc . ( GA-ASI ) has established a new Memorandum of Understanding ( MoU ) with its longtime partner Conflux Technology . The new MoU , signed this week at the AVALON 2023 Australian International Airshow and Aerospace & Defence Exposition , is the culmination of several years of collaborative work between GA-ASI and Conflux to build a flight-qualified Fuel Oil Heat Exchanger ( FOHE ) for GA-ASI platforms . “ We continue to work closely with Conflux on the design and manufacture of FOHE for our aircraft ,” said Ken Loving , GA-ASI Regional Vice President for Indo-Pacific . “ Through this new MoU , we will
establish a clear path to production for the heat exchanger components used by multiple GA-ASI production lines .” GA-ASI is a leading developer of unmanned aircraft , and Conflux is a thermal management system solution company headquartered in Australia . Conflux is an industryleading expert , mastering Additive Manufacturing ( AM ) for heat exchanger applications . “ Our continued partnership with General Atomics is a milestone for the commercialization of additively manufactured heat exchangers within the aerospace and defence markets , carrying the significant weight and performance benefits offered by these technologies towards production ,” said Abe Masoud , Conflux Business Development Manager - North America .
Interenergy awarded construction contracts
The Lempa River Hydroelectric Executive Commission ( CEL ) has awarded the contracts for the construction of two geothermal power plants in El Salvador to the English-Panamanian consortium InterEnergy following a tender process announced in August 2022 . The aforementioned geothermal power plants are the Chinameca geothermal power plant with an installed capacity of 20 MW and the San Vicente geothermal power with an installed capacity of 10 MW . Plans for the construction of these power plants had previously been announced by CEL
President Daniel Alvarez . According to the proposal submitted by InterEnergy , project execution is expected to be completed within two years . The plans to expand the geothermal power capacity of CEL are part of the government of El Salvador ’ s commitment through the subsidiary company LaGeo . The project will require an estimated investment of USD 620M . The expansion plan is carried out through a BOT model ( Construction Operation Transfer ) for the construction of the new geothermal plants . In this model , the company awarded the contract will
handle the investment and construction . After 20 years , the power plants will become the property of the state-controlled CEL .
Special Projects continues works at Cranfield University
Briggs & Forrester Special Projects have been awarded the mechanical and electrical services installation on the B084 / B085 Hangar Decarbonisation project at Cranfield University alongside R G Carter and CDG . The project will see two pre-WWII RAF hangars receive a major refurbishment to improve their energy efficiency and carbon footprint . Briggs & Forrester will be responsible for the full design and build works for the GBP 2.5M
electrical , mechanical , and plumbing services package to the hangars helping to transform the thermal performance and efficiency of the hangars with the aim of significantly reducing the carbon footprints of the buildings . To provide a sustainable solution , CDG designed an insulated , airtight ‘ box within a box ’ which sits inside the hangar . Services include the installation of new district heating pipework to the plate heat exchangers with associated valves ,
control , and pumps within the plantroom and a specialist Jetflo air induction heating system in the hangars . The work is being made possible by an award through the Public Sector Decarbonisation Scheme ( PSDS ) which is funded by the Department for Business , Energy and Industrial Strategy ( BEIS ) and delivered by Salix Finance . Once the works are completed , the heating demand of the buildings will be reduced by 75 % and the carbon footprint reduced
even further when connected to the district heating newly fitted with air source heat pumps , also funded through the project .
