Japan’s CCS Initiative
The Japanese government is driving its 2050 carbon neutrality goal through strategic
investments and advanced initiatives in Carbon Capture and Storage (CCS) starting in 2023.
Target 2050: Carbon neutral 2050: 120-240 M CO2-ton /year CCS
 2030: 6 – 12 M CO2-ton /year CCS

Advanced CCS Support Program by METI
Expected Emission Area

Ship Transport
Pipeline Transport

Act 2024: Act on CCS
Including mandatory monitoring ofreservoir conditions to detect any
CO2 leakage
Program 2023Advanced CCS Support Program by METI

6Concept of Biaxial PASS

Signal arrival of long distance can be achievedby a large number of stacks of continuous
source sweep.

Monitoring
SignalFurther more, we confirmed the arrival of the PASS signal
down to 2,200 m (to be published)Characteristics of PASS
• Movable by human• Battery operation assures the flexibility of PASS sourceposition• Servo-motor control enables multi-PASS operations
Compact, but Powerful• Noise from PASS is very low, and it is possible
to shoot in urban areas.

10Further Development of PASSThe University of Tokyo is carrying out long-term PASS operation tests
with the solar battery. Commercialization will be conducted by Wavelet, Inc.

Wavelet’s Business Model & Service
Wavelet offers a service to provide imaging data tocustomers using its proprietary PASS system.
Exploration: temporarily deploy
Monitoring: permanently install
