THE SEARCH AROUND THE STANDARD MODEL When the article Something more about particle accelerators (https://www.revistadyna.com/busqueda/algo-mas-sobre-aceleradores-de-particulas) appeared in DYNA in March 2012, the detection of the Higgs boson at CERN's Large Hadron Collider (LHC), which was made public on 4 July 2012, had not yet been announced. This completed the picture of elementary particles that we anticipated and that heads this news item, since the Higgs boson, together with the field that accompanies it, is what provides the mass to the other particles that interact with it.

EUROPEAN COMMUNITY SUPPORTS HYDROGEN The European Community intends to make a definitive effort for the deployment of hydrogen technology with a comprehensive action plan called IPCEI Hydrogen. It targets "innovation, demonstration and deployment of hydrogen technology" in the EC. It consists of four clusters of projects covering the entire hydrogen value chain: production, import, transport and end-use. The four clusters (waves) are: Hy2Tech, Hy2Use, Hy2Infra and Hy2Move. The first two were launched already in 2022 and the second two will be officially communicated in 2023 and 2024. Hy2Tech

A PROPOSAL FROM THE U.S. OFFICE OF NUCLEAR ENERGY. SMR (Small Modular Reactor) reactors are frequently mentioned in these NEWS items, although, except in China, where the first of them has been commissioned (https://www.revistadyna.com/noticias-de-ingenieria/nuclear-de-fision-unidades-grandes-o-pequenas-modulares), they are still only design projects or prototypes, more or less in their infancy. But the reality is that there is a favourable climate for the advancement of this technology.

GEOLOGICAL HYDROGEN EXTRACTION (GOLD): LIKE OIL? In the short time leading up to 2024, a wide range of reports have appeared in the media about the possibility of geological formations that have allowed the formation of areas in the subsoil with important gas deposits with a majority of hydrogen. Even the Financial Times asserts that "they could be a source of supply of this gas for hundreds of years".

THE HIDDEN PROBLEM BEHIND THE PROLIFERATION OF OFFSHORE WIND TURBINES In this section of DYNA, we have frequently reported on the efforts being made to find appropriate recycling for the blades removed from operating wind turbines (see https://www.revistadyna.com/noticias-de-ingenieria/el-primer-alabe-totalmente-reciclable-de-aerogenerador), although the results so far have not been encouraging: thousands of them are already piling up in landfills with no specific destination.

HOW DOES LITHIUM PROCUREMENT WORK FOR CAR MANUFACTURERS? The types of batteries most commonly found in electric vehicles contain lithium in weight percentages between 7.5 and 11%, so this material is considered basic to the advancement of these vehicles, and its procurement a key activity. But where does this material come from?

CO2 EMITTED CONTINUES TO INCREASE IN 2023, ALBEIT AT A LOWER INTENSITY According to the International Energy Agency (IEA), despite the growing demand for electricity, the expansion of solar photovoltaic and wind power generation, the maintenance of nuclear power and a growing fleet of electric vehicles, the increase in CO2 emissions in 2023 will be less pronounced than in 2022, when we were coming out of the pandemic.

FISSION NUCLEAR POWER: LARGE OR SMALL MODULAR UNITS? We are witnessing a debate in world nuclear fission energy technology that could mark its near future: whether the construction of large units (1,000 to 1,600 MW) of the EPR type will continue or whether the choice will be made in favour of small modular units, the so-called SMRs, which reach these powers by assembling several of them prefabricated in a single plant.

COLOURS OF HYDROGEN For the information of our readers, we take a look at the colours that in different texts usually appear as an attribute of the hydrogen that is produced or used.

THE ETERNAL RETURN OF THE HYPERLOOP More than ten years have passed since the visionary Elon Musk published his proposal for the much talked about tubular transport which, apart from having already had centuries of tests and experiences, had only consolidated itself as a modest means of movement for documents and/or parcels that other more modern means had ended up condemning to oblivion.
