landfill bio methaneOrganisations from sectors including agriculture, renewable energy, utilities and finance have written to the COP26 President Alok Sharma asking for his support towards unlocking the Anaerobic Digestion (AD) industry’s potential to address climate change and boost economic growth across the UK by transforming organic wastes into valuable bioresources.

The letter, signed by 19 organisations, urges Minister Sharma to become an advocate for improving waste management in the UK in the fight against climate change, by ensuring that all organic wastes are captured and transformed into valuable bioresources through anaerobic digestion technology – which gets the most out of such material – in order to rapidly decarbonise UK’s key industries such as transport, heat, agriculture and food and drink.

The group also ask for an immediate commitment to swiftly develop a policy framework for the AD sector to enable the industry to thrive and support the UK’s Net Zero and Global Britain ambitions, in particular addressing methane emissions this decade - and it's practical utilisation within the energy sector.

“The UK is currently missing a huge opportunity to build on an existing UK success story”, they write. “By turning all its organic wastes into bioresources, the AD industry could help:

  • The UK achieve carbon neutrality, including delivering 30% of the 5th Carbon Budget shortfall
  • Build back greener by creating 60,000 green jobs this decade
  • Bring over £5bn of private sector investment
  • Boost the UK’s exports to a $1trn global industry growing exponentially
  • Support the UK’s agriculture sector and food and drink industry.”

With the letter to Mr Alok Sharma, the signatories seek the COP26 President’s support in unlocking the industry’s potential as fast as possible – thus helping place the UK at the heart of the fight against climate change as well as realise the government’s vision for an environmentally responsible and economically strong “Global Britain”..

The 19 signatories to the letter are: ADBA; Biogen; CCm Technologies; CNG Fuels; Country Land and Business Association (CLA); Energy Networks Association (ENA) ; Evonik Industries ; Food and Drink Federation (FDF); Gas Vehicle Network (GVN); GFD; Grissan; Institution of Gas Engineers & Managers (IGEM); National Farmers Union (NFU); Northumbrian Water; Privilege Finance; Scotch Whisky Association (SWA); Severn Trent; SGN and United Utilities.

In my last blog I called for more effort on energy from wastes. I showed some nice pictures of Anaerobic Digester Plant in the Czech Republic. Who listens? Not many, I was not bold enough in my delivery..

So lets show what wastes we are talking about:

Waste destinations
This is where London sends at least 50% of their DOMESTIC wastes
London is a great example. It generated hundreds and thousands of tons per year of domestic waste plus a further 16 million tons of commercial wastes (including construction materials). No, that is a lot of stuff.

Combined Heat and Power Systems

Using energy efficiently has become a goal across industries in the past decade. Rising energy prices, an increasingly competitive marketplace, and environmental regulation of harmful pollutant emissions have all incited commercial and industrial energy users to search out the most efficient and cleanest ways to use energy.

Geothermal is:
• Cheaper than fossil and other renewable heat sources in many Member States according to the International Energy Agency ADEME, the French energy agency, found that the levelised cost of geothermal district heating was €15 MWh compared to €51 MWh from fossil sources already in 2019.
• Good for property values: In Sweden, household retail agencies found houses with Geothermal Heat Pumps increased property prices by about €10-12,000.
• The ‘go to’ solution for urban and rural cities: Cities all over Europe are opting for large-scale geothermal district heating systems.
• Grid balancing: Geothermal provides baseload electricity solving security of power supply threats by removing dependence on the import of fossil fuels from third countries.
• Available everywhere. Heat reservoirs and basins have only been mapped in some regions and in some countries. Over 25% of the EU’s population can be supplied by geothermal district heating by using resources mapped in 2013. Combined with geothermal heat pumps , nearly half of the EU’s heat demand can be met by 2030.
 

The term ‘geothermal energy’ refers to any heat derived from the ground, from depths of a few metres to multiple kilometres beneath the Earth’s surface.

 Low-grade heat stored in the shallow subsurface (<200 m) is largely derived from solar radiation that is absorbed by the ground and distributed via natural groundwater systems and artificial structures such as flooded coal mines. The ground acts as a solar battery and, for this heat, utilisation usually requires a heat pump. This energy is widely described as ‘ground-source energy’ or ‘shallow geothermal energy’.

There is no strict definition for ‘deep geothermal energy’, but the UK Government has adopted the term to refer to heat resources derived from depths of >500 m. The heat of the Earth increases with depth, a phenomenon described as the geothermal gradient. This heat is partly the primordial heat from when the Earth was formed and partly heat generated from within the Earth’s crust from the decay of mildly radioactive elements. This upward heat flux varies across the globe, but in the UK is around 27°C/km (Busby, 2014). Assuming an average annual air temperature of 12°C, this means that subsurface temperatures at 1000 m, 3000 m and 5000 m are around 39°C, 89°C and 139°C, respectively.
