Wärtsilä and Hitachi Zosen have announced plans to jointly develop and market fuel cell-based power applications for Japanese distributed energy markets.

The combined heat and power applications can be fuelled by either city gas or bio gas and will feature Wärtsilä designed fuel cell technology.

Wärtsilä’s fuel cells can utilise natural gas, city gas and biogas as fuel, and produce negligible nitrogen oxide (NOx), sulphur oxide (SOx) and particulate emissions, the company said in a statement.

The technology will be marketed by Hitachi Zosen.
