Hydrogen produced by electrolysis of water corresponds to an international need. H2V PRODUCT produces it massively to adapt it to the world market. The quotation of "green" hydrogen (H2V) will be significant of the stock market values of the 21st century. By combining CO2 from neighboring industries with the hydrogen produced by H2V PRODUCT, we manufacture biogas (CH4) or synthetic fuels (CH3OH). These products enter the circular economy. The equipment in our plants generates heat which can be upgraded by exchanger as a high-temperature fluid (550°F).
