Hybrid Solar-Biomass Plant Is Running
Two 20.5 MW heaters manufactured by Sugimat for Termosolar Borges, the world’s first solar thermal-biomass hybrid plant, are operating at full capacity after successful performance tests. The plant, unique in the world due to its process conditions, is the first to combine biomass and thermosolar energy through a field of parabolic trough mirrors. Thanks to this hybridization, the plant, located in Les Borges Blanques (Lleida, Spain), provides energy 24 hours a day. In addition to the heaters, Sugimat developed the remainder of the plant’s elements in turnkey mode.
Having successfully passed the performance tests, both heaters, fed with woody biomass and with a power of 20.5 MW, are now working in hybrid mode with a field of parabolic trough solar receivers up to 390ºC.
In addition to the boilers, Sugimat developed the heat recovery systems, integral control system and emission treatment.
Hybridization of thermal solar energy with biomass increases the plant’s operating time to 150%. In this way, an unmanageable energy asset such as a solar concentration plant is transformed into a manageable one, given that the plant can continue to produce electricity at night or on days without sun. Manageable plants with renewable energy are those required to carry out the decarbonization process, complementing the strong input of photovoltaic and wind power, thus guaranteeing the stability of the system and the balance between generation and consumption.
A proposed 450,000 metric tons per year industrial wood pellet mill to be built in Adel, Ga. is still an active project with nearly all of the pieces—including financing, equipment selection and air quality permit—in place, and construction expected to begin at mid-year 2022, according to Craig Whitlock, founder and…
Forest Service Backs Out Of Awarding Phase 2 Arizona Forests Restoration Contract; Uncertainties Persist For Novo Power
Anxious bidders for the Phase 2 contract that’s part of the federal 4 Forests Restoration Initiative (4FRI) seeking to treat and improve forest health conditions on more than 2.5 million acres across four Arizona national forests were told to wait a while longer after U.S. Forest Service (FS) officials abruptly…
Construction has started on Drax’s second satellite industrial wood pellet plant in Arkansas, this one in Russellville, Pope County, in northwestern Arkansas. Commercial operations are expected to begin at the plant in 2022. The move is part of a $40 million investment by Drax in the state…
