In a broader sense, the problems and limits of Country Email List hydrogen are similar to those of renewable energy infrastructures: the dependence on fossil materials for its construction, the use of minerals Country Email List whose use until now has been of relatively low intensity and the hoarding of territories to the detriment of communities and ecosystems. That, without mentioning the heavy transmission and storage infrastructure that has been the source of several of the environmental conflicts in Latin America. Emblematic in Chile was the Country Email List fight against the HidroAysén project. Which would have intervened in Chilean Patagonia to Country Email List convey hydroelectric power to the center of the country . The International Energy Agency has already warned Regarding the mismatch between the immense demand for minerals that would mean decarbonizing in compliance with the climate commitments of the Paris Agreement: the needs will simply exceed the volume of what is considered economically available and exploitable today. To Country Email List understand the depth of the problem of blindly betting on green hydrogen as a replacement for hydrocarbons, it is crucial to recognize the intertwining of renewable infrastructures with the biophysical processes that sustain them. In other words, expand the boundaries of the system and look at the expanded material footprint of every turbine, blade, and Country Email List solar panel. Seen from this distance, and taking into account the problems of the territories where these infrastructures are planned to be established. The promise of "carbon neutral" may fall apart. The issue Country Email List of scale cannot be ignored. The disposability of many of these infrastructures –sometimes with a useful life of less than two decades–, as well as their direct and indirect impact on the territories where they are installed, The violation of the rights of indigenous communities and nations Country Email List has become, around this issue, an inescapable fact. The irreparable intervention of ecosystems due to the fragmentation of forests or the loss Country Email List of delicate soils.

Which reinforces the current energy supply systems: the corporate Country Email List model, centralized and ignorant of the needs of millions of people who live in energy poverty. In short, green hydrogen works today, at least rhetorically, because it offers all the benefits of fossil fuels while solving the uncomfortable issue of carbon emissions, which is increasingly difficult to ignore in the emergency context. weather we are going Country Email List through. Feasibility and limits International organizations such as the Hydrogen Council they insist that hydrogen is a “mature” technology and ready for governments, investors and industries to bet on it. But, despite the statements, many Country Email List questions remain unanswered. Most critics have pointed out the various technical safety and handling problems that the commitment to green hydrogen could entail. Without going any further, they have shown Country Email List that the problems may not be very different from those caused by fossil fuels. But, on the other hand, beyond the fuel itself, there are not a few voices that have emphasized the renewable energy infrastructures that should be built Country Email List in association with green hydrogen. The scales that are managed for this purpose set off alarms about the possible socio-environmental impacts of this development. In many of the bets on green hydrogen, the precautionary Country Email List principle is conspicuously absent. For example, Chile's National Strategy for Green Country Email List Hydrogen initiated in 2020 describes as a successful scenario having 300 gigawatts (GW) of renewable energy associated with hydrogen by 2050, when today there are only 8 GW of non-conventional renewable energies in the National Electric System. However, little Country Email List is said about the added effect that boosting the infrastructure could have in what would be the nodal zones of hydrogen production – Magallanes in the extreme south of the country and Antofagasta in the north . And little or Country Email Listnothing is said about the fact that 72% of that hydrogen is expected to be destined abroad.
