RENEWABLE ENERGY VIEW 2015
| Mixed Energy From Waste (Combustion, Pyrolysis, Gasification, Landfill Gas - CHP, Heat & Power)
Energy from waste includes a range of different technologies and feedstocks, with differing potential for deployment. The picture is further complicated as the technologies are, to some extent, in competition for the same raw material. Landfill gas continues to make a substantial contribution to renewable electricity generation, but is likely to decline rather than grow as policy has moved away from supporting new projects, and existing sites produce less gas over time. These technologies offer a range of benefits beyond electricity generation, including enhanced greenhouse gas savings from avoided methane emissions from landfill.
MIXED WASTE TO ENERGY CONTEXT
l Includes landfill and sewage gas, conventional incineration and advanced treatments such as gasification
l Planning issues remain a significant barrier
l Availability of feedstock an issue, with concerns over impact of exports of UK waste to Europe
l Financial incentives for renewables pay on the renewable content of waste. Difficult to demonstrate for solid waste without being overly burdensome
ENERGY FROM WASTE - HEAT PRODUCTION
l PwC estimate that £1,366m was invested in the sector between 2010 – 2013 l In 2014, PwC calculate that an additional £824m was invested l Over the period 2015 – 2020, PwC forecast a further £4,695m could be invested in the sector (£m, Real 2012)
