Effect of Carbon Price Floor on Levelised Cost of Gas-Fired Generation Technology in the UK

The UK government implements carbon price floor to provide long-term incentive to invest in low-carbon technology, thus, fossil-fuel power plants have to face increasing carbon price. This report addresses the effect of carbon price floor on levelised cost of gas-fired generation technology through the levelised cost of electricity (LCOE) ap-proach with the estimation of carbon price floor. Finally, the comparison of levelised cost of electricity for all generation technology in the UK will be shown and discussed.

Forecasting the Impact of CCGT-CCS on the UK’s Electricity Market by LCOE

To achieve the target for building a low-carbon economy, the UK will have to build more low-carbon power plants to reduce carbon dioxide emissions from electricity generation. However, renewable energy is difficult to meet the increasing energy demand and keep lights on. This limitation of renewable could be solved by coal and gas-fired power station fitted with carbon capture storage (CCS) technology. CCS technology could capture up to 90% of carbon dioxide from emissions and allow fossil fuel power station to provide continuous low-carbon electricity power. This paper presents the levelised cost of electricity of CCGT with CCS and compared with renewable technology to forecast the impact of CCGT with CCS on the UK’s electricity market.

基于β-环糊精的有机小分子凝胶

环糊精是直链淀粉在环糊精葡萄糖基转移酶作用下生成的含有7个D-吡喃葡萄糖单元的环状低聚糖,具有斜截锥形空间立体结构,腔内疏水,腔外亲水。β-环糊精以其低廉的价格、良好的水溶性和生物相容性,在超分子化学领域得到广泛的应用。β-环糊精可用于凝胶的构筑,通常的方法是将β-环糊精接枝到高分子链上,再以得到的高分子链为凝胶因子构筑高分子凝胶。虽然基于β-环糊精的高分子凝胶得到了广泛的关注和研究,但是,直接以β-环糊精为凝胶因子构筑的有机小分子凝胶却鲜有报道。2010年,本课题组首次报道了一种基于β-环糊精和二苯胺的热致有机凝胶。此后,本课题组在β-环糊精有机小分子凝胶领域做了大量的研究工作。本文在实验室研究工作的基础上,首先介绍了β-环糊精有机小分子凝胶的分类和不同因素对凝胶形成的影响,然后深入探讨了β-环糊精有机小分子凝胶的形成机理,系统介绍了β-环糊精有机小分子凝胶的刺激响应性以及在药物载运领域的应用,最后,对β-环糊精有机小分子凝胶的发展前景进行了展望。
