EUROfusion announces the successful completion of third and final series of deuterium-tritium experiments at the UKAEA’s Joint European Torus

EUROfusion announces the successful completion of third and final series of deuterium-tritium experiments at the UKAEA’s Joint European Torus.

This campaign was all about studying the processes that will come into play in future fusion power plants. Scientists investigated fuel retention in walls and how to counter it, the effect of fusion neutrons on electronics together with CERN, controlling how heat is spread out in the exhaust and more. A leap ahead in our understanding of #fusionenergy.

The Lithuanian Energy Institute joined the JET activities in 2012, when preparations for the calibration campaign of the neutron detectors in the JET reactor took place. Participation in the JET research program allowed to engage not only in numerical studies, but also to participate in the JET experiment campaigns, where LEI has been performing data analysis of the plasma power distribution in the JET reactor since 2014.

The second General Assembly of the European Horizon project REEFLEX was held

On 21-22 November 2023 the second General Assembly of the European Horizon project “REplicable, interoperable, cross-sector solutions and Energy services for demand side FLEXibility markets“ (project acronym REEFLEX) was held. It reviewed the achievements of the past year, discussed the challenges faced, and set goals and objectives for the next 12 months. The project aims to create niche opportunities for new cross-sectoral energy services to be provided by SMEs and start-ups in demand flexibility markets. The success of the implementation of the solutions depends to a large extent on the active involvement of energy consumers.

In the coming period, Lithuanian Energy Institute will be responsible for the implementation of Task 7.4 “Social acceptance and behavioral aspects of consumers’ acceptance of technologies”.

The innovative solutions developed in this ambitious project will be demonstrated and tested in four main demonstration sites (Spain, Greece, Switzerland and Bulgaria). In addition, the service catalogue will be further rolled out in three more European countries for wider coverage (Turkey, Portugal, Denmark) and adoption, for a total of seven countries over the life of the project.

Jonathan Glennie, founder of Global Nation, visited LEI

on November 16, Jonathan Glennie, the founder of the “Global Nation” organization and a well-known expert in the field of international development and global cooperation, visited the Lithuanian Energy Institute. During the meeting, the energy situation in Lithuania and Europe, geopolitical challenges, international cooperation and sustainable development were discussed.

GIFFT Project Ignites Sustainable Innovation in European Glass Industry

On October 12, 2023, Brussels, marks the official commencement of the GIFFT project, a European Union-funded initiative aimed at transforming the glass industry’s sustainability landscape. Held at the Lithuanian Research Development and Innovation Liaison Office in Brussels, the kick-off meeting signifies the beginning of a collaborative effort to revolutionize glass manufacturing.

A Vision for Sustainable Glass Manufacturing
Europe leads in glass production, but the industry’s high energy consumption and CO2 emissions present challenges. GIFFT aims to overcome these hurdles by developing a groundbreaking heat production technology. Utilizing plasma-assisted combustion and gasification systems, the project will integrate bio-based solutions, such as biomass and waste, into glass manufacturing processes.

Kick-Off Meeting Highlights

The kick-off meeting for the GIFFT project marked a promising start with welcoming remarks from the project coordinator Dr. Nerijus Striūgas. Project Officer Javier Sanchez Lopez provided a thorough overview, detailing the project’s structure and objectives. Work package leaders presented insights into concept development, gasification, and combustion system plans, highlighting the project’s multifaceted approach. The meeting laid a strong foundation for collaborative efforts among partners, setting the stage for GIFFT’s pursuit of sustainable innovation in the glass industry.

The kick-off meeting of the GIFFT project took place: researchers will develop solutions for a more sustainable European glass industry

On October 12 the kick-off meeting of the LEI-coordinated GIFFT (Sustainable Glass Industry with Fuel-Flexible Technology) project took place.

Europe is the world leader in glass making, a highly energy-intensive industry that emits high amounts of CO2. The past century has seen improvements in the production process, but they are now approaching their limits. The objective of GIFFT is to develop a sustainable, hybrid, and biofuel flexible heat production technology and process that can be integrated into industrial glass manufacturing through efficient use of plasma-assisted combustion and gasification systems. An integrated heat production technology and process for glass manufacturing will be developed utilising biomass/waste and excess or cheap renewable electricity for syngas production, what will contribute to Europe’s progress and leadership for bioenergy integration into industrial settings. GIFFT will then develop and validate in an industrially relevant environment a fuel-flexible entrained flow gasifier (EFG) with a novel e-gasification function and a new plasma-assisted fuel-flexible gas burner for hybrid operation in glass furnaces. This will help diversify feedstock and improve the technological performance as well as cost reduction of bioenergy, ensuring a better circularity and increased use of renewables. The techno-economic feasibility and environmental impact of the technology will also be assessed to confirm that GIFFT contributes to an increased sustainability of biomass combustion and gasification and bioenergy value chains while reducing emissions.

The first newsletter of the LEI-coordinated HARMONISE project has been published

A year ago, the project “Towards harmonisation in licensing of future nuclear power technologies in Europe” (HARMONISE) was launched, today we invite you to familiarize yourself with the first newsletter of the project:

In the framework of the Euratom Research and Training Programme, HARMONISE will study relevant research and cooperation activities in standardization and nuclear safety considering also the lessons learnt from the stress tests performed in the EU. The project is coordinated by LEI and involves nine ETSON members along with partners representing research organisations, regulators and industry.
