2017-04-29 Report on opportunities and options for PtG in power systems
This report aims to investigate the role of Power-to-Gas (PtG) in the electrical system, in particular drawing its possible use in the different sectors of the electricity system (ES). Since one of the partners involved has special expertise in the operation of gas-fired power plants, coupling PtG with such plants was chosen as first application for a deeper investigation. The study includes the technical and legislative aspects involved in the use of Synthetic Natural Gas (SNG) as fuel for gas turbines.
2016-05-23 Review article on renewable Power-to-Gas: A technological and economic review
The Power-to-Gas (PtG) process chain could play a signiﬁcant role in the future energy system. Renewable electric energy can be transformed into storable methane via electrolysis and subsequent methanation. This article compares the available electrolysis and methanation technologies with respect to the stringent requirements of the PtG chain such as low CAPEX, high efﬁciency, and high ﬂexibility. Three water electrolysis technologies are considered: alkaline electrolysis, PEM electrolysis, and solid oxide electrolysis. Alkaline electrolysis is currently the cheapest technology; however, in the future PEM electrolysis could be better suited for the PtG process chain. Solid oxide electrolysis could also be an option in future, especially if heat sources are available.
