Lolland, Denmark

Lolland, Denmark

  • Target: 100% renewable energy
  • Status: Achieved
  • RES: Wind energy
  • Implementation: By 2006, the island of Lolland off the coast of Denmark was already producing 50% more power from wind than it could consume. It was decided that the best use of the excess renewable electricity was for the production of hydrogen for a hydrogen fuel cell plant. A hydrogen fuel cell is similar to a battery but requires a continuous feed of hydrogen and oxygen to work. Energy is needed to split water molecules (H2O) into its components hydrogen (H) and oxygen (O2). By using wind energy for this purpose, the hydrogen fuel cell plant was 100% renewable. Several major milestones in fuel cell cogeneration development on Lolland are of note. In November 2006, the first demonstration facility for residential Hydrogen Fuel Cell Combined Heat and Power (CHP)was built in the island's town of Nakskov and began producing both electricity and usable heat . In 2008, the facility was connected to existing island buildings. Small 2 kW Hydrogen Fuel Cell CHP units were also installed in 5 homes to show that houses could become their own efficient, secure, decentralized production units of heat and power, without any need for large, centralized utilities. Between 2010 and 2012, the decentralized Fuel Cell CHP program was expanded to 35-40 homes.
