The evolution on the energy market of natural resources (ie. crude oil, natural gas, et al.) and forecasts of energy needs make it necessary to seek new alternative sources of energy. The biggest hope is biofuels and hydrogen as fuels of the future. The connections between “green” chemistry and “good” systems for environment are a main interest of the environmental engineering. Literature searches, based on the use of SciFinder Scholar database showed for the keywords „catalysed decomposition of biomass”, „biofuels”, "hyrdogen storage» and “green batteries” more than 5000 literature references, among them 200 publications devoted to friendly systems for environment. I would like show new studies and look of the chemist on few chemical systems ”good” for natural environment. These studies concentrate about four main problems: (i) new ways of use starch and cereal in the environmental engineering processes (collectors of heavy metal ions, soil stabilizers, drilling muds, biofuels), (ii) catalytic properties of ceramic materials containing Li ions and metal transition ions in the process of thermal decomposition botanical origin systems, (iii) new systems of carbon nanotubes, fulerenes and graphene functionalized with organophosphate anions of selenoacids and tioacids and organic disulfide derivatives as potential electrode materials in lithium-ion batteries and (iv) new advanced materials for hydrogen storage system on the base of new super-light lithium alloys and hybrid materials based on carbon nanotubes and new super-light lithium alloys.
