Japan’s Energy Consumption Trends


Final energy consumption has increased about 1.
3

times since 1973, whereas
real
GDP
increased about 2.4 times in the same period.


Industrial sector energy consumption has leveled off, but a significant increase
in energy consumption has been observed in the consumer sector (commercial
and residential subsectors).

Outline of 2011 Strategy for Energy Efficiency Technologies


In order to achieve goals for 2030 included in the Basic Energy Plan, the 2011 Strategy for
Energy Efficiency Technologies aims to develop energy efficiency technologies, promote the
introduction and international deployment of such technologies, serve as a guideline for
stimulating economic growth and realize Japan’s aspiration to be the world’s leading nation in
terms of energy efficiency technologies.


This strategy therefore prioritizes wide
-
ranging energy efficiency technologies and selects key
technologies that can meaningfully contribute to Japan’s energy
-
saving efforts.

Strategic Innovation Program for Energy Efficiency Technologies


Based mainly on the 2011 Strategy for Energy Efficiency Technologies, the
New
Energy and Industrial Technology Development Organization (NEDO
) is promoting
seamless
development of key technologies that
are expected to achieve
significant energy
-
saving effects
following their
commercialization
.


(
FY2013 budget

by 2030
.



By introducing a stage gate evaluation system
, each technology development
plan will focus on achieving energy conservation targets.

Background and technology overview



Steam is depressurized to appropriate pressure levels by pressure reducing valves in order to be used in
manufacturing processes such as heating, distilling, drying and
sterilizing.
However, pressure energy released
in the depressurizing process is not utilized. Steam generators have been developed to generate electricity by
effectively recycling the untapped pressure energy.




Steam generators are equipped with screws that can rotate by a small amount of low
-
pressure steam. A
maximum power output of 160 kW has been achieved from steam at about 10 atmospheres.
