Trends en Uitdagingen
3
Belangrijke trends en uitdagingen
• Vraagstuk van klimaatverandering door menselijk handelen: verdere toename uitstoot CO 2 ; verdere toename concentratie van CO 2 in de atmosfeer; enorme voorraden fossiele brandstoffen versus de noodzaak CO 2 emissies teruggedrongen te hebben tot nul (resp. negatief!) rond 2060-2070.
• Lokaal: naderende uitputting van conventionele voorraden fossiele brandstoffen / vergroting importafhankelijkheid van fossiele brandstoffen.
• Winning van (een overvloed aan) onconventionele voorraden, nu met name in Noord-Amerika (schaliegas, schalie-olie, teerzanden).
• Verandering in kosten van diverse energiebronnen en energietechnieken, leidend tot veranderingen in concurrentiepositie van alle opties.
• Doorbraak hernieuwbare energie – winning van hernieuwbare energie begint het energieparadigma te veranderen; kansen voor nieuwe bedrijvigheid.
• Problemen bij de ontwikkeling en toepassing van kernenergie, waarop door verschillende landen zeer veschillend wordt gereageerd (bijv. Duitsland vs UK).
• Onderbenutting van de grote potenties van energie- en materiaalbesparing.
• Moeizame introductie van de grootschalige toepassing van CCS.

emission budget, and required CO

price in GEA
• Climate Change: Allowable budget CO 2 period 2010-2100: 940-1460 GtCO 2 emissions in the in total.
Note: This budget is achieved in 30-45 years if we stay at present level of CO 2 emissions!
• CO 2 price in GEA: At least 15-45 $/tCO 2 now; up to 110 $/tCO 2 or above in later years.
Note: At present, the CO 2 price on the spot market is about 4 Euro per tonne CO 2 .

Major developments in renewables till 2011
• The
renewable resource base
is sufficient to meet potentially more than 10 times the present global energy demand.
•
Renewables grow strongly
in all end-use sectors (power; heating and cooling; transport).
•
In 2010 more than $230 bln investments
($-2005) in renewables. Investments in ’new renewables’ from about $2 bln in 1990, to about $190 bln in 2010. Global investments in RE increased further in 2011 (by 17%). •
Net investments in renewable power capacity
(including larger-scale hydropower)
exceeded that of fossil fuels
in 2011.
•
About half of the new electricity capacity installed
worldwide in 2011 was renewable based.
• Globally, an estimated
5 million people
work directly or indirectly in renewable energy industries.
•
At least 118 countries
now have renewable energy targets in place, and 109 countries have policies to support renewables in the power sector.

Towards a Sustainable Future
(based mainly on GEA chapter 17)
10
Objectives GEA Sustainable Development energy back-casting scenario for 2050
•
Support economic growth at recent historic rates
(2% a year increase of per capity income, on average
) .
•
Almost universal access to electricity and cleaner cooking by 2030
(diffusion of clean technology; extension of grids).
•
Reduce air pollution impacts on health, adhering to WHO guidelines
(reduced 5 million premature death due to air pollution by 50% by 2030).
•
Avoid dangerous climate change; stay below + 2 o C above pre industrial global mean temperature with more than 50% likelyhood
(CO2 emission peak by 2020; 30-70% reduction in 2050; negative emissions later).
•
Improve energy security through enhanced diversity, limited energy trade and resilience of energy supply by 2050
(reduce share oil import in primary energy by 30-80%; decrease energy intensity; increase local energy supply options; infrastructure expansion; storage and back-up capacity).
• And in the process:
address issues like peak oil and nuclear proliferation challenges.

Conclusions about a.o. the role of renewables in 2050 energy supplies
• At least the historical rate of improvement of the energy efficiency a year should be achieved, preferably more ( decrease en. intens.: 1.5-2.2% a year ).
• Low carbon energy shares in primary energy at least at 60-80% by 2050.
• Strong growth in renewable energy , beginning immediately and reaching 165-650 EJ a year by 2050 - about 30-75% of primary energy demand (and in some regions more than 90% of this demand in 2050).
• Increasing requirement for storage technologies , apart from measures like grid extension, to support system integration of intermittent renewable.
• Growth in bioenergy to 80-140 EJ a year by 2050. Strong growth of liquid biofuels in the short to medium term. Thereafter, the mix of liquid and gaseous fuels depends on transportation system choices.
• Nuclear energy may play an important role, but it is also possible to phase out nuclear, still meeting the GEA sustainability targets.
• Fossil CCS as an necessity or an optional bridge in the medium term; biomass plus CCS to achieve negative CO2 emission in longer term; cumulative storage of CO2 up to 250 GtCO2 by 2050.
20
Some essential technology-related requirements for radical energy transformation
GEA highlights the following essential requirements
: 1. Significantly larger investments in energy efficiency improvements , especially end-use, across all sectors; 2. Rapid escalation of investments in renewable energies (hydropower, wind, solar energy, modern bioenergy, and geothermal) as well as the smart grids, super grids and storage technologies that enable renewable energies to become the dominant sources of energy ; 4. Use of fossil fuels and bioenergy, with CCS, at the same facilities for efficient co-production of multiple energy carriers and chemicals; 5. Full-scale deployment of CCS ; and 6. On one extreme nuclear energy could make a significant contribution to the global electricity, but in the other, it could be phased out.
21
Major challenges for renewables, both technical and economic
• Reducing costs through learning and scale-up; • Creating a flexible (but predictable) investment environment that provides the basis for scale-up and diffusion; • Integrating renewable energies into the energy system; • Enhancing research and development to ensure technological advances; and • Assuring the sustainability of the proposed renewable technologies .
