Carbon Minus House to Use Lithium-Ion Batteries

Keywords: Climate Change Energy Conservation Manufacturing industry 

Sumitomo Forestry Co., a major Japanese homebuilder, announced on September 15, 2010, that it would develop a life cycle carbon minus (LCCM) house by applying lithium-ion batteries (LIBs) as storage batteries. The company plans to utilize the LIBs installed in the Nissan Leaf, an electric vehicle (EV) to be released by Nissan Motor Co.

Sumitomo Forestry has been developing LCCM houses that produce negative emissions of carbon dioxide over their total life cycle. This goal can be achieved by introducing technology that thoroughly reduces the carbon dioxide released during construction, operation, deconstruction and disposal of the houses, by focusing on energy-efficient lifestyles to make full use of such technologies, and by using renewable energy sources such as solar.

The company has been jointly conducting validation tests on storage batteries using LIBs for electricity storage in residential houses with various companies, including NEC Corp. They will further conduct tests using LIBs developed for the Nissan Leaf aiming for the future commercialization of LCCM houses. The use of storage batteries is essential for the energy self-sufficiency of houses and promising for future second-life use of EV batteries. This will contribute to significant reductions in initial costs and the realization of a low-carbon society through efficient use of resources.
