CORPORATE RESPONSIBILITY 4. Current use and future of gas Estimates of global natural gas reserves available have increased along with the utilisation of unconventional gas reserves such as shale gas. At the moment natural gas is anticipated to last for around 100 years at the current rate of consumption. In 2009 the world’s proven natural gas reserves were 187,400 billion m3. The replacement of coal by natural gas is regarded as the fastest way to cut down carbon dioxide emissions at the global level. The availability of natural gas does not prevent greater use in Finland, either, but Finnish debate has had a focus on the increased use of biofuels and nuclear power. A total of 35% of district heat and 14% of electricity produced in Finland was generated using natural gas in 2010. Combined heat and power production (CHP) will also remain the biggest use for natural gas in the next few years. We promote the launch of new technologies and offer our customers diverse opportunities to utilise gas in a more energyefﬁcient and environmentally friendly manner. Our R&D activity supports our strategy to become Finland’s leading bio-based gas producer. As well as bio-based gases, we are studying options such as fuel cells, hydrogen technology, liqueﬁed natural gas (LNG) and carbon capture and storage (CCS). Biogas can be turned into a noteworthy biofuel for municipal CHP plants on the southern coast in particular through the utilisation of ﬁeld biomass at digestion facilities and through the production of bio-synthetic natural gas from wood using gasiﬁcation.The combined potential for bio-based gases in Finland is at least 15 TWh, which is around a third of current natural gas consumption. A broad raw material base increases diversity in gas sourcing, and a locally sourced fuel increases security of supply in gas sourcing.
