Energy Technology Vision 2100

M. Akai; AIST 4


Development of “Energy Technology Vision 2100”

Purpose• To establish METI strategic energy R&D plan

– To consider optimum R&D resource allocation.– To prioritize energy R&D programs and specific

project of METI.• To prepare strategy for post-Kyoto and

further deep reduction of GHG• To develop technology roadmap to be

reflected in METI's energy, environmental and industrial policy

M. Akai; AIST 5


Why to consider Ultra Long-term?

• Timeframe for future risk or constraint– Resource (10s ~ 100yrs?)– Environment (100 ~ 1000 yrs)

• Long lead time for energy sector in general– Research and development to

commercialization– Market diffusion – Infrastructure development– Stock turnover time (10s yrs)

M. Akai; AIST 6


Scope of Work

• Timeframe – Vision: - 2100– Technology roadmap: -2100

• Benchmarking years: 2030 and 2050

• Approach– To introduce backcasting methodology– To compile experts' view – To confirm long-term goal using both top-

down and bottom-up scenario analysis

Methodology - Backcasting

Exploratory (opportunity-oriented):• what futures are likely to happen? ⇒ Forecasting

– starts from today’s assured basis of knowledge and is oriented towards the future

Normative (goal-oriented): • how desirable futures might be

attained? ⇒ Backcasting– first assesses future goals, needs, desires,

missions, etc. and works backward to the present

Basic Recognition on the Energy Sector

• Constraints on energy connect directly to the level of human utility (quantity of economic activity, quality of life).

• Consideration of future energy structure should take into account both resource and environmental constraints.

• The key to achieve a truly sustainable future is technology.

• However, there is great uncertainty because various kinds of options are selected in the actual society.

M. Akai; AIST 11


Premises

• Resource and environmental constraints do not degrade utility but enrich the human race (improve utility)

• To develop the technology portfolio for the future in order to realize it through development and use of the technologies.

• Not to set preference to specific technologysuch as hydrogen, distributed system, biomass, etc.

M. Akai; AIST 12


AssumptionsDeveloping a Challenging Technology Portfolio• The effect of modal shift or changing of

lifestyle were not expected.• Although the assumption of the future

resource and environmental constraints includes high uncertainties, rigorous constraints were assumed as "preparations".

• To set excessive conditions about energy structure to identify the most severe technological specifications. – As a result, if all of them are achieved, the

constraints are excessively achieved.

M. Akai; AIST 13


Desirable Futures

• Society where the economy grows and the quality of life improves

• Society where necessary energy can be quantitatively and stably secured

• Society where the global environment is maintained

• Society where technological innovation and utilization of advanced technology are promoted through international cooperation

• Society with flexible choices depend on national and regional characteristics

M. Akai; AIST 14


Assumptions towards 2100

• Population and economy– To increase continuously

• Energy consumption– To increase following the increase in

population and GDP

To Overcome Constraints ---

• Sector specific consideration– Residential/Commercial – Transport – Industry– Transformation (Elec. & H2 production)

• Definition of goal in terms of sector or sub-sector specific CO2 emission intensity.

• Identification of necessary technologies and their targets Demand sectors and their typical CO2 emission intensity

Industry : t-C/production volume = t-C/MJ × MJ/production volume Commercial : t-C/floor space = t-C/MJ × MJ/floor space Residential : t-C/household = t-C/MJ × MJ/household Transport : t-C/distance = t-C/MJ × MJ/distance (Transformation sector: t-C/MJ) Conversion

Significance of CCS in Case A(Fossil + CCS)

• ... while it can reduce CO2 emission generated from use of non-conventional fossil resources significantly, it is merely a transitional solution ... However, this has an immediate effect, and can be regarded as an emergency measure.

• Potential of CO2 sequestration is supposed to be high worldwide. On the other hand, there may be a limitation for geological sequestration potential in Japan. However, if ocean sequestration is realized, the potential in Japan becomes larger.

M. Akai; AIST 25


Sector Specific Considerations on CCS

• Transport– If we try to make CO2 emissions zero in

the transport sector, we have to supply energy to vehicles in the form of electricity or hydrogen which are supplied by nuclear power, renewables, or fossil fuels with CO2 capture and sequestration.

• Industry– The process and scale in this sector

enables CO2 capture and sequestration if required when using fossil resources.

Possible Solution with the Combination of Three Cases (1/2)

• ... capacity for geological sequestration is considered to have limitations. We have to consider ocean sequestration to satisfy the required capacity ...

• Case A (fossil + CCS) cannot be a long-term solution due to the limitation of fossil resources. Therefore, the combination of case C (renewable + energy-saving) and case B (nuclear) is desirable ... on a long-term basis, by avoiding rapid climate change by CCS as required on a mid-term basis.

M. Akai; AIST 28


Possible Solution with the Combination of Three Cases (2/2)

• ... combination of these cases can vary according to situations in the future. It is important to prepare technologies through R&D for social and economic changes at various occasions in the future.

• As a result, we can acquire an optimal and robust energy system structure...

• Also, if we prepare for the three extreme cases ..., their synergy effect enables the reduction of fossil resources consumption and CO2 emissions...

M. Akai; AIST 29


Ongoing and Future Tasks

• To coordinate with domestic activities on short- & mid-term energy strategy– Development of roadmaps based on

forecasting approach– Prioritization on energy R&D (incl. CCS) in

Council for Science and Technology Policy– Development of National Energy Policy– Revision of energy related action plans

• To coordinate with international activities

M. Akai; AIST 30


Related International Activities

• International Energy Agency– Energy Outlook 2006– Energy Technology Perspective– Response to Gleneagles Action Plan

• Suggesting cooperation of IEA and CSLF

• Asia-Pacific Partnership for Clean Development and Climate

• Work Plan includes collaboration on CCS

Implications from Scenario Study

• Case-A “Fossil + CCS” would contribute to hydrogen economy but not be a sustainable option from the viewpoint of resource depletion.

• Nuclear and CCS (especially as a mid-term option) would increase the flexibility of energy supply and demand structure.

• Energy efficiency is the key!

M. Akai; AIST 41


Concluding Remarks• On-going R&D under METI• Towards the Future of CCS

M. Akai; AIST 42


Towards the Future of CCS- Bridging over Science and Society -

• Social acceptance for the technology⇑

• Conformity with regulations– London Convention, OSPAR, Domestic Laws, etc.– Action for amendment, if necessary

• Definite recognition by IPCC and UNFCCC• Better communication

– Audience: general public, scientists, industries, policy makers, NGOs, etc.

⇑• Accumulation of scientific knowledge

M. Akai; AIST 43


CCS R&D Projects under METI

• Ocean Sequestration(Environmental Assessment for CO2 Ocean Sequestration)

– 1997 - 2001 (Phase-1)– 2002 - 2006 (Phase-2)

• Geological Sequestration– 2000 - 2004 (Phase-1)– 2005 - （Phase-2）

• ECBM– 2002 - 2006 (Phase-1)

M. Akai; AIST 44


Other CCS Research under METI

• Accounting Rules on CO2 Sequestration for National GHG Inventories [ARCS] (2002 -)– Development of accounting methodology– Contribution to NGGIP– Policy studies including CCS-CDM

• Environmental Impact and Safety Management based on Natural Analogue(2005 - )

• Methodology of Applicability of CCS to Kyoto Mechanism including CDM (2004 - )

• Public Perception on CCS (2002 - )– Cooperation with AGS Project

M. Akai; AIST 45


Strategic Action Plan on Putting CO2Sequestration on the Viable Policy Agenda
