DNV Energy, in partnership with PGL, Airtricity
and Scottish
Enterprise have launched the WindStore Project.
As the use of renewable sources of energy,
including wind power, increases on a global level, the
effective storage of energy is a major challenge affecting both the economics
and efficiency of future renewable energy generation capacity. The WindStore
Project is focused on large scale energy storage concepts in the The study is expected to have a
significant impact on the more effective use of renewable energy sources
(particularly wind energy), the security of energy supply, reduction of
carbon emissions, and less dependency on connections to the national power
grid. Its findings are likely to have equal applicability to energy storage
in the non-renewable sector. Compressed air energy storage (CAES)
involves compressing air and pumping it into a subsurface void or reservoir
for storage. The compressed air can then be pumped to the surface when
required and used to drive a gas turbine and generate power. This has already
been done at two ~300 MW plants (in The WindStore
Project explores innovative ways of using the energy storage potential of
porous storage media and other options both onshore and offshore. It has the
potential to significantly improve the economics of wind power generation. |
