Concentrated Solar Heat (CSH) Decarbonizing Process Heat

Concentrated Solar Heat (CSH) ‘Decarbonizing Process Heat’

About 54% of all energy delivered globally is deployed in the industrial sector, 67% for process heat,
75% of which is used at temperatures below 400 o Celsius. Further, according to The International
Renewable Energy Agency (IRENA), an estimated 60% of all heating demands required for industrial
purposes are met at temperatures below 250 °C.

Concentrated Solar Heat (CSH) technology could deliver a nationally significant fraction of this process heat requirement in the food & beverage, pharmaceutical, chemicals, mining, cosmetics, textile, pulp, agriculture and paper sectors, where a 500 kW t system (1, 000m 2 of collector area) will typically generate approximately 1.2 MWhrs of clean thermal energy/year, displacing approximately 175 tons of CO 2 emissions over the same period. This heat would be transported in water, air, thermic fluid or steam for cleaning, pasteurization, cooking, drying, dyeing, bleaching, sterilization, distillation, evaporation, heat
treatment, etc.

Parabolic Dishes: Thermofield Industrial’s proprietary designs of fixed – focus Scheffler parabolic dishes
come in sizes of 16 and 32 m 2 (6 and12 16 kWp) raising up to 600 O Celsius at the focus.
Parabolic dish technology is suited to small installations (<300 kW) delivering process heat at
temperatures above 300 o Celsius for distillation, large-scale cooking, pyrolysis and hot air/oven operations and applications that require some form of thermal energy storage (TES).

Linear Fresnel Lens Technology: Linear Fresnel lens technology is the state-of-the-art of high
temperature solar heat generation. Its flexibility, modularity, ease of deployment and low space
requirement makes it particularly suited to industrial and utility-scale installations operated at final
temperatures in the range of 100-200 o Celsius. Thermofield Industrial will launch its proprietary
Fresnel design in the form of a 32m 2 Industrial Solar Module (ISM 32) in the first quarter of 2026.
