The
German
engineering
giant
unveiled
a
geothermal-friendly
variant
of
its
SST-400
steam
turbine,
which
is
already
used
in
industrial
applications
and
at
concentrating
solar
power
(CSP)
plants.
Siemens
says
global
installed
geothermal
capacity
is
expected
to
triple
to
31GW
by
2020.
The
German
group
names
the
US,
the
Philippines
and
Indonesia
as
existing
major
geothermal
markets,
with
untapped
potential
in
areas
including
East
Africa,
Russia
and
Turkey.
The
company
already
provides
a
range
of
equipment
to
geothermal
projects,
but
the
market
for
steam
turbines
is
dominated
by
Japanese
suppliers
such
as
Toshiba…
