Lithuanian Sustainable
Energy Vision 2050
The Lithuanian
Vision2050 is similar to the vision for EU; but developed to
fit the visions of the Lithuanian INFORSE member Atgaja. The proposed
development follows in general the same path as in the European vision,
but given the large biomass potential, the strong growth in construction
and transport, and the need to replace nuclear power without increasing
gas demand, the vision has a strong focus on actions that can be
implemented cost-effectively until 2020, and include more growth
than the vision for EU. It includes a transition of the energy
supply and demand with phase-out of fossil and nuclear energy over
a 50-year period,
starting with the closure of the Ignalina nuclear power plant in 2009.
This
Vision include a special
strategy for immediate actions (pdf
file), for Lithuania
until 2020.
The
Vision was developed in 2006, and the current version (December
2006) is still open for updates as more information becomes available.
Comments are welcome.
Factor 4 for Energy Efficiency
In line with INFORSE’s global vision for sustainable energy, the
Lithuanian Vision is based on increase of energy efficiency to reach
an average level in 2050 similar to best available technologies today.
Most energy consuming equipments will be changed several times until
2050, and if new generations of equipment are made with optimal energy
performance, and markets are made to promote the most efficient technology,
it will not be a problem to reach today's best available technology,
even though the efficiency gains required are very large, - in the order
of 4 times, similar to an annual increase of efficiency of over 2% per
year from 2010. This will not happen by itself, given that the "natural" technological
development in EU has been about 1% per year. It will require concerted
actions from stakeholders involved, but if it is done on EU-scale and
the market therefore is large for each new generation of efficient equipment,
the changes will be cost-effective. The extra equipment costs will be
off-set by energy savings. To realise this, it is, however, necessary
to go beyond the conservatism of many market players in this field, and
develop a truly enabling market for energy efficiency throughout the
society.
The Challenge of Reducing Heat Consumption
For buildings the situation is different from equipment because buildings
often have lifetimes of 100 years or more. Most of the houses to be heated
in 2050 are probably already built. For Lithuania, the proposed energy
conservation plans for domestic and service sectors should be realised
and the efforts should be continued in the following decades.
Efficient Transport
For transport is assumed that the conversion-efficiency from fuel to
transport-work is increased 2.5 times (from current 15- 20% in combustion
engine systems to 50% in fuel cell systems with break-energy recoverage;
direct electrically driven vehicles have even higher efficiency), and
that the vehicles will be equipped with recoverage of break-energy, so
the "end-use" of energy in transport is limited to the unavoidable
friction losses in transport (except for aviation). This increase is
expected to happen until 2050. Most of the changes are only expected
2030-2050, and the efficiency increase 2000-2030 is only expected
to be 22%. Faster improvements in transport efficiencies would be possible.
Growth Factors
The growth of energy services, i.e. heated floor space, transported goods
and people, energy consuming production, is expected to continue for
2-3 decades and then level off for most sectors towards the end of the
50-year period of the vision. Assumed growth in activities for Lithuania:
·
Floor space, households: 1% annual increase from 2010 (6% in total 2000-2010)
· Floor space service sectors: 2% annual increase until 2020, then reduced
to 1.5% 202-2030 and then to 1% per year in the following decades.
·
Electric appliances in households and service: 1–1.5% higher
annual growth than floor space. This will lead to a doubling in the service
sectors in the period 2000-2050 and a 65% increase in household
sector in the period.
·
Industry: no growth in physical production volume, i.e. 0% in growth
2000-2050; but increase electrification leading to 20% increase
in the drivers for electricity for industrial production.
·
Personal transport: the vision includes a doubling of private car use
2000-2030, following current high growth. Then we expect a stabilisation
while rail use is expected to increase 3 times and bus use 3.2 times
in the period.
· Freight transport: the vision includes a 3.4 times increase in the period
for road, rail and water transports, based on current strong growth.
Pipeline transport is expected to decrease 30% with decreased transport
of fossil fuels and a small development of hydrogen pipelines.

Renewable Energy
As a fraction of primary energy, renewable energy use is expected to
reach almost 15% in 2010, 37% in 2020, 45% in 2030, 60% in 2040 and over
95% in 2050. For electricity the renewable share is below the share of
primary energy 2000-2010, but the will change until 2020, where it will
be higher.
The most important developments are in windpower and biomass including
important use of agricultural land for biomass plantations, use of crops
for biofuels and use of straw for heating and for combined heat and power
(CHP) production. The use of agricultural land for energy plantations
for solid biomass is expected to be 2200 km2 until 2020 (7% of agricultural
land).
Also increase use of solar, geothermal and small hydro is included in
the vision.

Nuclear and Fossil Energy
Nuclear energy is expected to be phased out as the current nuclear reactor
in Ignalina is stopped in 2009. Fossil fuel use is expected to grow
until 2010 and then gradually be phased out until 2050.

Energy Conversion,
Hydrogen& Heat Pumps
The energy conversion system will also have to be changed. The electric
grid is likely to increase in importance, because electricity will also
be used for transport, directly or via conversion to hydrogen. The increasing
dependence on intermittent electricity supply makes it necessary to have
energy storage in some forms and maybe flexible electricity consumption.
Analysis shows that the current hydro pump storage will be sufficient
until 2030, maybe longer.
Gas networks are expected to have decreasing importance. They might play
a role for transportation of hydrogen or biogas, but probably not for
long-distance transport.

Graph: Development of electricity production and sources, following
Vision2050
An evaluation of
the hourly variation of electricity and heat loads and the windpower
production was made on the EnergyPlan model for the year
2020, with input data for the vision's energy balance for 2020 and
with variations from typical Danish conditions. The results were that
CHP
would cover 67% of electricity production, windpower 21%, hydro 7%
and power-only plants 5%. Of the district heat load, CHP would cover
55%
while the rest would be from heating plants. There would be no critical
electricity excess or lack of electricity in any hours, but electricity
export in some periods with high windpower. If the export is not possible,
windpower or CHP production could be reduced in these hours. The results
are consistent with the above results that is based on yearly energy
balances.

Energy Trade
Energy trade is expected to be much less than today, only a moderate
electricity exchange is expected. Electricity exchange with little
net import or export is likely to continue, to exchange electricity
from renewable sources such as hydropower (currently imported from
Latvia on seasonal basis) and wind power.
