Engineered geothermal systems represent a significant unutilized energy source, with the potential to assist in meeting growing demands clean, renewable energy. Traditional use water as working fluid. An alternative fluid is carbon dioxide which offers benefits including favorable thermodynamic and transport properties for sequestration. important feature that CO2 does not dissolve mineral salts, this will serve reduce fouling corrosion problems afflict piping surface equipment conventional...

CO2-based enhanced geothermal systems (EGSs) have been examined from a reservoir-oriented perspective, and as result thermodynamic performance is well explored. Economics of the system are still not understood, however. In this study, economics EGS technology explored for an optimized power plant design best-available cost estimation data. We demonstrate that near-optimum turbine exhaust pressure can be estimated surface temperature. identify achievable cooling temperature important economic...

A 100,000 t/year demonstration project for carbon dioxide (CO 2 ) capture and storage in the deep saline formations of Ordos Basin, China, has been successfully completed. Field observations suggested that injectivity increased nearly tenfold after CO injection commenced without substantial pressure build-up. In order to evaluate whether this unique phenomenon could be attributed geochemical changes, reactive transport modeling was conducted investigate -water-rock interactions changes...

A new anisotropic soft material - a liquid crystal 'hydroglass' (LCH) is created from aqueous suspensions of nanocrystalline cellulose (NCC) colloidal rods. Under specific conditions, the NCC suspension separates into colloid-rich attractive glass matrix phase and coexisting phase. LCH provides similar viscoelastic properties to polymer gels, but permits reversibly-orientating rods through shear forces.

Abstract Avacopan, a C5a receptor antagonist (C5aR) presents new therapeutic option to improve outcomes in ANCA‐associated vasculitis (AAV). Here we present case report of patient initially requiring kidney replacement therapy (KRT), where avacopan was added as an additional adjunctive agent late the treatment course.

Ground source heat pumps (GSHPs) are one of the most widespread forms geothermal energy technology. They utilise near-constant temperature ground below frost line to achieve energy-efficiencies two or three times that conventional air-conditioners, consequently allowing a significant offset in electricity demand for space heating and cooling. Relatively mature GSHP markets established Europe North America. implementation Australia, however, is limited, due high capital price, uncertainties...
