Among the international efforts to
curb global warming, practical application of CO₂ removal technology
and improvement of power-generation efficiency — for reducing CO₂
emission from thermal power plants (which will probably remain the prime source
of power in future) — will, at the very least, become urgent issues over the
next several decades. Accordingly, the Hitachi Group is aiming at further
improving efficiency with the following main developments: 700°C USC coal-fired
thermal power, coal-gasification power generation, a high-efficiency turbine,
and a new thermal-cycle system. By performing CO₂-recovery tests on a
coal-gasification power plant and developing an oxy-combustion-system coal
boiler suited to CO₂ recovery, we are also actively engaged in
practical application of CCS technology which incurs low energy
loss.
