Elmar Theune: Climate-Smart Dairy Webinar

  1. 1. Climate-Smart Agriculture Webinars December 1st 2016 Manure digestion The valley of death Elmar Theune
  2. 2. Dutch Agriculture and greenhouse gas emissions • 2016: Dutch Agriculture is responsible for 14% of Dutch greenhouse gas emissions (26,4 Mton). • Since 1990 a reduction of 20%. 2 december 2016 Ministerie van Economische Zaken2

  4. 4. 2 december 2016 Ministerie van Economische Zaken4 Manure digestion • Methane production is the result of biological processes. • Rumen fermentation is hard to diminish. Research is ongoing. • The technology for manure digestion is available (prototypes; demonstration projects), but is not used. • The business case for manure digestion requires too much to subsidize (NB: the Dutch Subsidy for Sustainable Energy is a tender that subsidizes the cheapest options first)
  5. 5. Valley of death: • The manure digester has to be customized to each farm. Too expensive àNo renewable energy subsidy by the government. • Manure digestion is not the core business of farmers. àNo priority for investment and no willingness to do maintenance. • Few installations àNo teams available for failure management. • The banks had no confidence àNo business case; no finance. 2 december 2016 Ministerie van Economische Zaken5
  6. 6. Suggested solution by the dairy sector The Sustainable Dairy Chain (by mouth of FrieslandCampina) proposed a solution: • The sustainable Dairy Chain guaranties a certain quantity of installations. • The farmers are enabled to lease the digester. • Installation firms develop three standard manure digester and have teams for failure management. • The price can drop and the business case improves. • To make this possible the ministry is asked for a temporary subsidy. 2 december 2016 Ministerie van Economische Zaken6
  7. 7. Reaction of the Ministry of Economic Affairs The ministry is not in favor of specific subsidies. But: • Climate change and the energy transition are major policy issues. • The dairy sector has limited options for greenhouse gas reduction. • Manure digestion is a serious option for greenhouse gas reduction. • Methane is a source of renewable energy. So: • The minister has decided in favor of a specific subsidy for manure digestion. • A open tender on price is organized for about 200 mono-digesters. 2 december 2016 Ministerie van Economische Zaken7
