Current and Projected Costs for Biofuels from Algae and Pyrolysis

The presentation explored the question of whether the U.S. government is spending money on the right technology pathways. Costs were presented for biofuel produced from pyrolysis, algae, Fischer-Tropsch (FT), and methanol-to-gasoline (MTG) routes.

Germany: Siemens to Convert Wind Energy into Gas

Siemens AG (SIE) has revealed its intention to introduce technology in 2015 that will enable conversion of wind-turbine electricity into gas, providing wind farms with an alternative revenue stream when the grid is fully charged.

Michael Weinhold, Chief Technology Officer of Siemens’ Energy Businesses, says the electrolyser, a soccer-field sized plant that converts power into storable hydrogen, is in the testing phase, reports Bloomberg. It offers a promising capacity necessary for overcoming the challenge of how to harness fluctuating electricity output from wind farms, especially at night when demand is the lowest.

Munich-based Siemens allocates 1 billion euros ($1.3 billion) on annual bases to devising new technology for the energy industry. Wind farms have faced hardship in commercial terms because power cannot be stored on a large scale, however the converted hydrogen can be stored by feeding it into the gas grid.

“The main problem today is the mismatch of renewable power generation and demand,” Weinhold said in an interview. “If we can offer solutions to solve that, we have a business case.”
