Renewables production technologies

In the short to medium term, renewable fossil based energy will remain important. C02 sequestration and the consequential importance of hydrogen imply a large interest in hydrogen production technologies, its storage and subsequent conversion. Electrocatalysis may be expected to be of increasing importance.

Production technology that enables hydrogen to be produced from domestic sources - initially natural gas and eventually clean coal, nuclear energy, biomass and other renewable sources. 

Goal Research and develop low cost, highly efficient hydrogen production technologies from diverse, domestic sources, including fossil, nuclear, and renewable sources. 

Despite the advantages of biosurfactants, they will not replace the synthetic ones unless there is a great improvement inbiosurfactant production technology in order to reduce its costs. Thus, the use of renewable, readily available, and relatively inexpensive raw materials, considering that B. subtilis may synthesize biosurfactants from different carbon sources (20,21), may account for the feasibility of this bioprocess.

Hydrogen production from fossil fuels will continue for the foreseeable future, given the large resource and the established industrial base. Research is focused on improving the environmental aspects of fossil fuel use, and a number of papers address advanced hydrogen production technologies that reduce or eliminate C02 emissions from the production process. In addition, hydrogen production from biomass, a renewable resource with the potential for zero net C02 emissions, is discussed.

At midsize scale, a few tens of megawatts, both natural gas and renewable energy technologies offer production possibilities. Megawatt-scale production is especially attractive for biomass-based energy sources. Natural gas production at this scale could provide an efficient response to early market demand for hydrogen, but could not offer sufficient scale economies to compete effectively in mature hydrogen markets.
