Perovskite solar cells (PSCs) are promising candidates for the next generation of solar cells because they are easy to fabricate and have high power conversion efficiencies. However, there has been no detailed analysis of the cost of PSC modules. We selected two representative examples of PSCs and performed a cost analysis of their productions: one was a moderate-efficiency module produced from...

This paper proposes an approach for improving the plant efficiency by reducing the heat rejection temperature of power cycle using Kalina Cycle System 11 (KCS11) which is integrated at the steam condenser of a 500 MWe SubC (subcritical) coal-fired power plant. It is modelled by using power plant simulation software ‘Cycle Tempo’ at different plant operating conditions. Results show t...

Contrary to conventional fossil fuel-based electricity generation technologies, renewable energy centered specifically small hydropower, release a lesser amount of anthropogenic greenhouse gases but are normally more expensive. A major segment the capital investment in current hydropower scenario accounts for equipment and construction process costs. The cost administration generally limited an...

Green hydrogen development is still at a niche stage and faces several technical & commercial barriers. Among them the high LCOH (Levelized Cost of Hydrogen) green hydrogen, predominantly due to cost renewable electricity. In recent years, research studies have focused on finding most cost-effective electricity option feed electrolyzers for producing hydrogen. However, their findings su...

This paper presents a post-audit of a 1978 examination of economic impacts of geothermal energy development in the Imperial Valley Region of California. It is intended to demonstrate the usefulness of this approach in evaluating the validity of renewable resource development in general. The 1978 examination based its estimates on a projection of 4500 MW of electricity generation capacity develo...

The levelized cost of energy (LCOE) presents the energy-normalized cost of a generation asset by considering all associated costs (investment and operation) and total generated energy over its life cycle. As LCOE is a levelized value, it provides a quick and easy measure to compare different energy resource technologies with different characteristics. The LCOE calculation for large-scale power ...

This paper evaluates a novel receiver design concept that implements photovoltaic (PV) cells on heat shields and bellows shields to capture optical spillage from central receiver and parabolic trough concentrating solar power (CSP) plants, generating electricity from concentrated light that would otherwise be wasted. A combination of conventional silicon and multi-junction concentrating PV (CPV...
