IANOS: Innovative energy storage solutions for the decarbonization of geographical islands

Geographical Islands experience harsh climate conditions resulting in diminished reliability of their grid. IANOS, a project funded by the European Commission, is developing technologies to overcome these challenges and allow for the secure decarbonisation of islands. The project will deploy and use storage technologies in two islands: Terceira, in Portugal, and Ameland, in the Netherlands. These include a 100kW/3kWh flywheel; thirty-five 2kW private fuel cells; sixteen 3kW/3kWh electrochemical batteries; two large-scale Battery Energy Storage System (BESS); a biobased saline battery of 120kWh; and twenty-four heat batteries of 3.5kWhth. These technologies, managed by an intelligent Virtual Power Plant (iVPP) also developed within the project, will be used for the maximisation of demand-side self-consumption, as well as for the provision of ancillary services, targeting the maximum economic and environmental benefit for the population and the island’s grid. In this paper, the specifications of each storage technology are described, as well as the impacts on the grid stability. The role of storage technologies in the decarbonisation of geographical islands will be emphasized

Exposure to thioguanine during 117 pregnancies in women with inflammatory bowel disease

BACKGROUND: Safety of thioguanine in pregnant patients with inflammatory bowel disease (IBD) is sparsely recorded. This study was aimed to document the safety of thioguanine during pregnancy and in birth. METHODS: In this multicenter case series, IBD patients treated with thioguanine during pregnancy were included. Data regarding disease and medication history, pregnancy course, obstetric complications and neonatal outcomes were collected. RESULTS: Data on 117 thioguanine-exposed pregnancies in 99 women were collected. Most (78%) had Crohn's disease and the mean age at delivery was 31 years. In eighteen pregnancies (15%) IBD flared. Obstetric and infectious complications were seen in 15% (n=17) and 7% (n=8) of pregnancies, respectively. Ten pregnancies (8.5%) resulted in a first trimester miscarriage and one in a stillbirth at 22 weeks gestational age. Congenital abnormalities were observed in one induced abortion (trisomy 21) and in one of the live-born children (cleft palate) . In total 109 neonates were born from 101 singleton pregnancies and 4 twin pregnancies. In the singleton pregnancies, ten children were born prematurely and ten were born small for gestational age. Screening for myelosuppresion was performed in sixteen neonates (14.7%); two had anemia in umbilical cord blood. All outcomes were comparable to either the general Dutch population or to data from 3 Dutch cohort studies on the use of conventional thiopurines in pregnant IBD patients. CONCLUSION: In this large case series the use of thioguanine during pregnancy is not associated in excess with adverse maternal or neonatal outcomes
