Waste from olive oil production, and in particular ground olive pits, could be recycled and transformed into clay bricks and cement paste to be used as building materials, for the manufacture of decorative furniture and even for the production of acoustic barriers.Is it time for hydrogen in the post-pandemic era? Corinna acosta by corinna acosta 14 mayo 2020 0 linkedinfacebooktwitterwhatsapp is it time for hydrogen in the post-pandemic era? The Spain Mobile Number List government is spending trillions on post-covid-19 stimulus, but should it be directed toward advancing green hydrogen technology? What kind of green stimulus does the world need? “technologies that reduce carbon emissions are one of the most important targets for the trillions of dollars of spending linked to stimulus programs to alleviate the economy after the coronavirus,” concluded more than 200 central bankers, ministers of finances from the group of 20 and leading academics in a study published this week. There are three sets of clean energy technologies that policymakers can focus on, each at different stages of development.



The most advanced are wind and solar, which are already cheaper to build than conventional energy almost everywhere in the world, and in many places they are even cheaper than the operation of current fossil energy generators. The best way for governments to increase the share of wind and solar generation is probably to encourage the construction of transmission networks and reform energy markets to reduce the advantages of fossil fuels, while leaving financing and construction real to private investors. There are also lithium-ion batteries that are in an early stage of development and are not very competitive with existing technologies. In most places, it still costs more to provide peak power to the grid with a backup battery than with a gas turbine, and the cost of an electric car is substantially higher than a gasoline one.







However, inroads are also being made there: electric vehicles are much cheaper to operate than conventional ones, and batteries large enough to support the high demand for energy generated can compete with gas by integrating generators. Wind and solar. As a result, batteries are on track to reduce the use of conventional technologies by the middle of this decade. It is tempting to conclude that the fundamentals of clean energy are so positive that they hardly need support. That ignores the fact that power generation, and passenger cars, are a surprisingly small part of the world's emissions. «if both sectors switched completely to zero carbon energy tomorrow, we would only have eliminated between 40% and 50% of our carbon output.
