Powering Agri-food Value Chains with Geothermal Heat
This report is a guidebook for policy makers which provides recommendations for accelerating the deployment of geothermal energy in the agri-food value chains. The recommendations are derived from an analysis of key success factors that enabled the development of various agri-food applications in different part of the world. The guidebook benefited from the input of 23 experts drawn from 17 member countries and partner organisations of the GGA, and other organisations.
The proposed recommendations address challenges related to inadequate data on geothermal resources and existing heating demand for agri-food applications, absent or misaligned enabling framework conditions, inadequate financing, and lack of awareness. In addition, the guidebook recommends the adoption of methodologies to determine the tariff for geothermal heat as well as for quantifying the socio-economic impacts of deploying geothermal heat in the agri-food sector, as tools for supporting decision making.
Geothermal: The Solution Underneath
Geothermal energy has been improving in efficiency, and there are now more than 15.4 gigawatts (GW) of installed geothermal power plants globally. Estimates show that geothermal energy can supply about 8.3% of the total electricity needs of the world and serve about 17% of the global. Geothermal technology can produce clean, baseload and flexible power generation, making it a promising option for the transition to clean energy and a more sustainable economic model. In addition to power generation, geothermal energy has multiple applications as a heat source or sink in end-use sectors such as building, agrifood and industry.

United Nations framework Classification for Geothermal Energy: Pilot Applications in the Caribbean, Ethiopia and Indonesia
United Nations framework Classification for Geothermal Energy: Pilot Applications in the Caribbean, Ethiopia and Indonesia The joint report by IRENA, the International Geothermal Association (IGA) and the World Bank’s Energy Sector Management Program (ESMAP), supported by United Nations Economic Commission for Europe (UNECE), highlights the main challenges and way forward to adopt the United Nations Framework Classification (UNFC) for geothermal energy resources, based on experiences and lessons learned in a pilot programme carried out in the Caribbean, Ethiopia and Indonesia to adapt the broader UNFC specifications and guidelines to geothermal energy resources.
The UNFC guidelines and codes is a universal standardized language for reporting of resource potential in a manner that enables projects for different resources types and jurisdictions to be comparable, therefore facilitating decision making for investment.

Integrating low-temperature renewables in district energy systems Guidelines for policy makers
Integrating low-temperature renewables in district energy systems Guidelines for policy makers A report developed by IRENA in collaboration with Aalborg University and with the support of an Advisory Group of District Heating and Cooling Experts, drawn from the constituency of the GGA and other institutions. It provides guidelines to policy makers at the national and local level, urban planners, district heating and cooling utilities, etc. on the options and available tools for facilitating the integration of low temperature renewable energy resources, including geothermal and solar thermal, into new and existing district heating and cooling networks and buildings.
The key topics addressed in the report include strategic planning for heating and cooling; technical challenges and solutions on the integration of renewables into existing or new buildings and networks; and enabling regulatory conditions, business models, and financing.

Geothermal Development in Eastern Africa: Recommendations for power and direct use
This regional assessment of geothermal development for electricity and direct use in the countries of the East African Rift and the Comoros was carried out through a consultative process with relevant stakeholders, under the umbrella of the Global Geothermal Alliance.
The report provides an updated overview of the status (as of 2020) of geothermal development in selected countries of the East African Rift region, identifies bottlenecks hindering further development, and provides key recommendations to policy makers and key stakeholders regarding possible options to accelerate the deployment of geothermal energy in the region.
